A Brief Guide about Docker for Developer in 2023

What is Docker? Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. Docker is based on the idea of containers, which are a way of packaging software in a format that can be easily run on any platform.

Docker provides a way to manage and deploy containerized applications, making it easier for developers to create, deploy, and run applications in a consistent and predictable way. Docker also provides tools for managing and deploying applications in a multi-container environment, allowing developers to easily scale and manage the application as it grows.

What is a container? A container is a lightweight, stand-alone, and executable package that includes everything needed to run the software, including the application code, system tools, libraries, and runtime.

Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package. It allows developers to package an application with all of its dependencies into a single package, making it easier to deploy and run the application on any platform. This is especially useful in cases where an application has specific requirements, such as certain system libraries or certain versions of programming languages, that might not be available on the target platform.

What is Dockerfile, Docker Image, Docker Engine, Docker Desktop, Docker Toolbox? A Dockerfile is a text file that contains instructions for building a Docker image. It specifies the base image to use for the build, the commands to run to set up the application and its dependencies, and any other required configuration.

A Docker image is a lightweight, stand-alone, executable package that includes everything needed to run the software, including the application code, system tools, libraries, and runtime.

The Docker Engine is the runtime environment that runs the containers and provides the necessary tools and libraries for building and running Docker images. It includes the Docker daemon, which is the process that runs in the background to manage the containers, and the Docker CLI (command-line interface), which is used to interact with the Docker daemon and manage the containers.

Docker Desktop is a desktop application that provides an easy-to-use graphical interface for working with Docker. It includes the Docker Engine, the Docker CLI, and other tools and libraries for building and managing Docker containers.

Docker Toolbox is a legacy desktop application that provides an easy way to set up a Docker development environment on older versions of Windows and Mac. It includes the Docker Engine, the Docker CLI, and other tools and libraries for building and managing Docker containers. It is intended for use on older systems that do not meet the requirements for running Docker Desktop. Docker Toolbox is no longer actively maintained and is being replaced by Docker Desktop.

A Fundamental Principle of Docker: In Docker, an image is made up of a series of layers. Each layer represents an instruction in the Dockerfile, which is used to build the image. When an image is built, each instruction in the Dockerfile creates a new layer in the image.

Each layer is a snapshot of the file system at a specific point in time. When a change is made to the file system, a new layer is created that contains the changes. This allows Docker to use the layers efficiently, by only storing the changes made in each layer, rather than storing an entire copy of the file system at each point in time.

Layers are stacked on top of each other to form a complete image. When a container is created from an image, the layers are combined to create a single, unified file system for the container.

The use of layers allows Docker to create images and containers efficiently, by only storing the changes made in each layer, rather than storing an entire copy of the file system at each point in time. It also allows Docker to share common layers between different images, saving space and reducing the size of the overall image.

Some important Docker commands: – Here are some common Docker commands: – docker build: Build an image from a Dockerfile – docker run: Run a container from an image – docker ps: List running containers – docker stop: Stop a running container – docker rm: Remove a stopped container – docker rmi: Remove an image – docker pull: Pull an image from a registry – docker push: Push an image to a registry – docker exec: Run a command in a running container – docker logs: View the logs of a running container – docker system prune: Remove unused containers, images, and networks – docker tag: Tag an image with a repository name and tag There are many other Docker commands available, and you can learn more about them by referring to the Docker documentation.

How to Dockerize a simple application? Now, coming to the root cause of all the explanations stated above, how we can dockerize an application.

First, you need to create a simple Node.js application and then go for Dockerfile, Docker Image and finalize the Docker container for the application.

You need to install Docker on your device and even check and follow the official documentation on your device. To initiate the installation of Docker, you should use an Ubuntu instance. You can use Oracle Virtual Box to set up a virtual Linux instance for that case if you don’t have one already.

Caveat Emptor Docker containers simplify the API system at runtime; this comes along with the caveat of increased complexity in arranging up containers.

One of the most significant caveats here is Docker and understanding the concern of the system. Many developers treat Docker as a platform for development rather than an excellent optimization and streamlining tool.

The developers would be better off adopting Platform-as-a-Service (PaaS) systems rather than managing the minutia of self-hosted and managed virtual or logical servers.

Benefits of using Docker for Development and Operations:

Docker is being talked about, and the adoption rate is also quite catchy for some good reason. There are some reasons to get stuck with Docker; we’ll see three: consistency, speed, and isolation.

By consistency here, we mean that Docker provides a consistent environment for your application through production.

If we discuss speed here, you can rapidly run a new process on a server, as the image is preconfigured and is already installed with the process you want it to run.

By default, the Docker container is isolated from the network, the file system, and other running processes.

Docker’s layered file system is one in which Docker tends to add a new layer every time we make a change. As a result, file system layers are cached by reducing repetitive steps during building Docker. Each Docker image is a combination of layers that adds up the layer on every successive change of adding to the picture.

The Final Words Docker is not hard to learn, and it’s easy to play and learn. If you ever face any challenges regarding application development, you should consult 9series for docker professional services.

Open Platform For Enterprise AI Avatar Chatbot Creation

How may an AI avatar chatbot be created using the Open Platform For Enterprise AI framework?

I. Flow Diagram

The graph displays the application’s overall flow. The Open Platform For Enterprise AI GenAIExamples repository’s “Avatar Chatbot” serves as the code sample. The “AvatarChatbot” megaservice, the application’s central component, is highlighted in the flowchart diagram. Four distinct microservices Automatic Speech Recognition (ASR), Large Language Model (LLM), Text-to-Speech (TTS), and Animation are coordinated by the megaservice and linked into a Directed Acyclic Graph (DAG).

Every microservice manages a specific avatar chatbot function. For instance:

Software for voice recognition that translates spoken words into text is called Automatic Speech Recognition (ASR).

By comprehending the user’s query, the Large Language Model (LLM) analyzes the transcribed text from ASR and produces the relevant text response.

The text response produced by the LLM is converted into audible speech by a text-to-speech (TTS) service.

The animation service makes sure that the lip movements of the avatar figure correspond with the synchronized speech by combining the audio response from TTS with the user-defined AI avatar picture or video. After then, a video of the avatar conversing with the user is produced.

An audio question and a visual input of an image or video are among the user inputs. A face-animated avatar video is the result. By hearing the audible response and observing the chatbot’s natural speech, users will be able to receive input from the avatar chatbot that is nearly real-time.

Create the “Animation” microservice in the GenAIComps repository

We would need to register a new microservice, such “Animation,” under comps/animation in order to add it:

Register the microservice

@register_microservice( name=”opea_service@animation”, service_type=ServiceType.ANIMATION, endpoint=”/v1/animation”, host=”0.0.0.0″, port=9066, input_datatype=Base64ByteStrDoc, output_datatype=VideoPath, ) @register_statistics(names=[“opea_service@animation”])

It specify the callback function that will be used when this microservice is run following the registration procedure. The “animate” function, which accepts a “Base64ByteStrDoc” object as input audio and creates a “VideoPath” object with the path to the generated avatar video, will be used in the “Animation” case. It send an API request to the “wav2lip” FastAPI’s endpoint from “animation.py” and retrieve the response in JSON format.

Remember to import it in comps/init.py and add the “Base64ByteStrDoc” and “VideoPath” classes in comps/cores/proto/docarray.py!

This link contains the code for the “wav2lip” server API. Incoming audio Base64Str and user-specified avatar picture or video are processed by the post function of this FastAPI, which then outputs an animated video and returns its path.

The functional block for its microservice is created with the aid of the aforementioned procedures. It must create a Dockerfile for the “wav2lip” server API and another for “Animation” to enable the user to launch the “Animation” microservice and build the required dependencies. For instance, the Dockerfile.intel_hpu begins with the PyTorch* installer Docker image for Intel Gaudi and concludes with the execution of a bash script called “entrypoint.”

Create the “AvatarChatbot” Megaservice in GenAIExamples

The megaservice class AvatarChatbotService will be defined initially in the Python file “AvatarChatbot/docker/avatarchatbot.py.” Add “asr,” “llm,” “tts,” and “animation” microservices as nodes in a��Directed Acyclic Graph (DAG) using the megaservice orchestrator’s “add” function in the “add_remote_service” function. Then, use the flow_to function to join the edges.

Specify megaservice’s gateway

An interface through which users can access the Megaservice is called a gateway. The Python file GenAIComps/comps/cores/mega/gateway.py contains the definition of the AvatarChatbotGateway class. The host, port, endpoint, input and output datatypes, and megaservice orchestrator are all contained in the AvatarChatbotGateway. Additionally, it provides a handle_request function that plans to send the first microservice the initial input together with parameters and gathers the response from the last microservice.

In order for users to quickly build the AvatarChatbot backend Docker image and launch the “AvatarChatbot” examples, we must lastly create a Dockerfile. Scripts to install required GenAI dependencies and components are included in the Dockerfile.

II. Face Animation Models and Lip Synchronization

GFPGAN + Wav2Lip

A state-of-the-art lip-synchronization method that uses deep learning to precisely match audio and video is Wav2Lip. Included in Wav2Lip are:

A skilled lip-sync discriminator that has been trained and can accurately identify sync in actual videos

A modified LipGAN model to produce a frame-by-frame talking face video

An expert lip-sync discriminator is trained using the LRS2 dataset as part of the pretraining phase. To determine the likelihood that the input video-audio pair is in sync, the lip-sync expert is pre-trained.

A LipGAN-like architecture is employed during Wav2Lip training. A face decoder, a visual encoder, and a speech encoder are all included in the generator. Convolutional layer stacks make up all three. Convolutional blocks also serve as the discriminator. The modified LipGAN is taught similarly to previous GANs: the discriminator is trained to discriminate between frames produced by the generator and the ground-truth frames, and the generator is trained to minimize the adversarial loss depending on the discriminator’s score. In total, a weighted sum of the following loss components is minimized in order to train the generator:

A loss of L1 reconstruction between the ground-truth and produced frames

A breach of synchronization between the lip-sync expert’s input audio and the output video frames

Depending on the discriminator score, an adversarial loss between the generated and ground-truth frames

After inference, it provide the audio speech from the previous TTS block and the video frames with the avatar figure to the Wav2Lip model. The avatar speaks the speech in a lip-synced video that is produced by the trained Wav2Lip model.

Lip synchronization is present in the Wav2Lip-generated movie, although the resolution around the mouth region is reduced. To enhance the face quality in the produced video frames, it might optionally add a GFPGAN model after Wav2Lip. The GFPGAN model uses face restoration to predict a high-quality image from an input facial image that has unknown deterioration. A pretrained face GAN (like Style-GAN2) is used as a prior in this U-Net degradation removal module. A more vibrant and lifelike avatar representation results from prettraining the GFPGAN model to recover high-quality facial information in its output frames.

SadTalker

It provides another cutting-edge model option for facial animation in addition to Wav2Lip. The 3D motion coefficients (head, stance, and expression) of a 3D Morphable Model (3DMM) are produced from audio by SadTalker, a stylized audio-driven talking-head video creation tool. The input image is then sent through a 3D-aware face renderer using these coefficients, which are mapped to 3D key points. A lifelike talking head video is the result.

Intel made it possible to use the Wav2Lip model on Intel Gaudi Al accelerators and the SadTalker and Wav2Lip models on Intel Xeon Scalable processors.

Nothing encapsulates my misgivings with Docker as much as this recent story. I wanted to deploy a PyGame-CE game as a static executable, and that means compiling CPython and PyGame statically, and then linking the two together. To compile PyGame statically, I need to statically link it to SDL2, but because of SDL2 special features, the SDL2 code can be replaced with a different version at runtime.

I tried, and failed, to do this. I could compile a certain version of CPython, but some of the dependencies of the latest CPython gave me trouble. I could compile PyGame with a simple makefile, but it was more difficult with meson.

Instead of doing this by hand, I started to write a Dockerfile. It's just too easy to get this wrong otherwise, or at least not get it right in a reproducible fashion. Although everything I was doing was just statically compiled, and it should all have worked with a shell script, it didn't work with a shell script in practice, because cmake, meson, and autotools all leak bits and pieces of my host system into the final product. Some things, like libGL, should never be linked into or distributed with my executable.

I also thought that, if I was already working with static compilation, I could just link PyGame-CE against cosmopolitan libc, and have the SDL2 pieces replaced with a dynamically linked libSDL2 for the target platform.

I ran into some trouble. I asked for help online.

The first answer I got was "You should just use PyInstaller for deployment"

The second answer was "You should use Docker for application deployment. Just start with

FROM python:3.11

and go from there"

The others agreed. I couldn't get through to them.

It's the perfect example of Docker users seeing Docker as the solution for everything, even when I was already using Docker (actually Podman).

I think in the long run, Docker has already caused, and will continue to cause, these problems:

Over-reliance on containerisation is slowly making build processes, dependencies, and deployment more brittle than necessary, because it still works in Docker

Over-reliance on containerisation is making the actual build process outside of a container or even in a container based on a different image more painful, as well as multi-stage build processes when dependencies want to be built in their own containers

Container specifications usually don't even take advantage of a known static build environment, for example by hard-coding a makefile, negating the savings in complexity

[v-for-violet]

i fucking hate modern devops or whatever buzzword you use for this shit

i just wanna take my code, shove it in a goddamn docker image and deploy it to my own goddamn hardware

no PaaS bullshit, no yaml files, none of that bullshit

just

code -> build -> deploy

please 😭

Unleashing Efficiency: Containerization with Docker

Introduction: In the fast-paced world of modern IT, agility and efficiency reign supreme. Enter Docker - a revolutionary tool that has transformed the way applications are developed, deployed, and managed. Containerization with Docker has become a cornerstone of contemporary software development, offering unparalleled flexibility, scalability, and portability. In this blog, we'll explore the fundamentals of Docker containerization, its benefits, and practical insights into leveraging Docker for streamlining your development workflow.

Understanding Docker Containerization: At its core, Docker is an open-source platform that enables developers to package applications and their dependencies into lightweight, self-contained units known as containers. Unlike traditional virtualization, where each application runs on its own guest operating system, Docker containers share the host operating system's kernel, resulting in significant resource savings and improved performance.

Key Benefits of Docker Containerization:

Portability: Docker containers encapsulate the application code, runtime, libraries, and dependencies, making them portable across different environments, from development to production.

Isolation: Containers provide a high degree of isolation, ensuring that applications run independently of each other without interference, thus enhancing security and stability.

Scalability: Docker's architecture facilitates effortless scaling by allowing applications to be deployed and replicated across multiple containers, enabling seamless horizontal scaling as demand fluctuates.

Consistency: With Docker, developers can create standardized environments using Dockerfiles and Docker Compose, ensuring consistency between development, testing, and production environments.

Speed: Docker accelerates the development lifecycle by reducing the time spent on setting up development environments, debugging compatibility issues, and deploying applications.

Getting Started with Docker: To embark on your Docker journey, begin by installing Docker Desktop or Docker Engine on your development machine. Docker Desktop provides a user-friendly interface for managing containers, while Docker Engine offers a command-line interface for advanced users.

Once Docker is installed, you can start building and running containers using Docker's command-line interface (CLI). The basic workflow involves:

Writing a Dockerfile: A text file that contains instructions for building a Docker image, specifying the base image, dependencies, environment variables, and commands to run.

Building Docker Images: Use the docker build command to build a Docker image from the Dockerfile.

Running Containers: Utilize the docker run command to create and run containers based on the Docker images.

Managing Containers: Docker provides a range of commands for managing containers, including starting, stopping, restarting, and removing containers.

Best Practices for Docker Containerization: To maximize the benefits of Docker containerization, consider the following best practices:

Keep Containers Lightweight: Minimize the size of Docker images by removing unnecessary dependencies and optimizing Dockerfiles.

Use Multi-Stage Builds: Employ multi-stage builds to reduce the size of Docker images and improve build times.

Utilize Docker Compose: Docker Compose simplifies the management of multi-container applications by defining them in a single YAML file.

Implement Health Checks: Define health checks in Dockerfiles to ensure that containers are functioning correctly and automatically restart them if they fail.

Secure Containers: Follow security best practices, such as running containers with non-root users, limiting container privileges, and regularly updating base images to patch vulnerabilities.

Conclusion: Docker containerization has revolutionized the way applications are developed, deployed, and managed, offering unparalleled agility, efficiency, and scalability. By embracing Docker, developers can streamline their development workflow, accelerate the deployment process, and improve the consistency and reliability of their applications. Whether you're a seasoned developer or just getting started, Docker opens up a world of possibilities, empowering you to build and deploy applications with ease in today's fast-paced digital landscape.

openjdk - Official Image | Docker Hub

[rejszelde]

véres verejtékkel kb 2 hét alatt felkapartam a tudást abszolút nulláról a következőkben:

- docker kezelés (image build, container indítás)

- hogyan építünk fel egy imaget .net szerverhez, react apphoz

- docker compose up-down

- github workflow action (hogy egyáltalán mi az, hogy működik)

- full ci build github workflowban

- docker containerek indítása github workflowban

- teljes kicheck-becheck, fájlok manipulálása build előtt github workflowban, context behatárolása

- artifactok feltöltése-letöltése, verziószámok kezelése github workflowban

- docker adminisztrálása a github workflowban

jelzem, mindezt úgy 2 hét alatt, hogy előtte soha, egy betűt sem ismertem ezekből külön-külön sem, de maga a containerization témakör is nagyon távoli volt számomra.

egy dolgot nem tudok csak megoldani:

github workflowban felpattintok 3 különböző docker containert, amik közül az egyik az api szerver, a másik a react app, ami használná az apit, a harmadik meg egy cypress teszt, ami a react appra targetál. az istenért nem tudom a networkot összelőni. tudom, hogy az api containere definiálja az api_default networkot, látom a docker networkok között, és a react app containere is látja elvileg, mivel a compose fájlban beállítottam external networknek. ennek ellenére a cypress nem tud rácsatlakozni. már csak ez hiányzik, hogy befejezzem a missiont.

[meguminmaniac]

I can see how someone might cut corners and not cross-compile or use a cross-building docker image and just dump the source code on the device to compile locally. But shipping a Raspberry Pi image logged into Slack is pretty wild.

first rule of software development is just deploy that shit baby

[agapi-kalyptei]

man, i LOVE the rush you get in the days before burning out

Took me a few days but I managed to upgrade a bunch of old code and packages, opened literally hundreds of documentation and troubleshooting tabs (and closed most of them! only about 1152 to go), BUT I managed to get the Heptapod runners to actually build and push docker images on commit, AND it deploys it to my kubernetes cluster.

And yeah I know that someone who just uses some free tier cloud services would take 2.4 minutes to do the same, but I get the extra satisfaction of knowing I can deploy a k8s cluster onto literally any machine that's connected to the internet, with ssl certificates, gitlab, harbor, postgres and w/e. Would be also nice to have an ELK stack or Loki and obviously prometheus+grafana, and backups, but whatever, I'll add those when I have actually something useful to run.

Toying with the idea of making my own private/secure messaging platform but it wouldn't be technically half as competent as Signal; However I still want to make the registration-less, anon ask + private reply platform. Maybe. And the product feature request rating site. And google keep that properly works in Firefox.

Anyway, realistically though I'll start with learning Vue 3 and making the idle counter button app for desktop/android, which I can later port to the web. (No mac/ios builds until someone donates a macbook and $100 for a developer license, which I don't want anyway.) This will start as a button to track routine activities (exercise, water drinking, doing dishes), or a button to click when forced to sit tight and feeling uncomfortable (eg. you can define one button for boring work meetings, one for crowded bus rides, one of insomnia, etc). The app will keep statistics per hour/day/etc. Maybe I'll add sub-buttons with tags like "anxious" "bored" "tired" "in pain" etc. I'm going to use it as a simpler method of journaling and keeping track of health related stuff.

After that I want to extend the app with mini-games that will be all optional, and progressively more engaging. At the lowest end it will be just moving mouse left and right to increase score, with no goal, no upgrades, no story, etc. This is something for me to do when watching a youtube tutorial but feeling too anxious/restless to just sit, and too tired to exercise.

On the other end it will be just whatever games you don't mind killing time with that are still simple and unobtrusive and only worth playing when you're too tired and brain dead to Do Cool Stuff. Maybe some infinite procedurally generated racing with no goals, some sort of platformer or minecraft-like world to just walk around in, without any goals or fighting or death. Or a post-collapse open world where you just pick up trash and demolish leftovers of capitalism. Stardew Valley without time pressure.

I might add flowcharts for ADHD / anxieties, sort of micro-CBT for things that you've already been in therapy for, but need regular reminders. (If the app gets popular it could also have just a these flowcharts contributed from users for download).

Anyway, ideas are easy, good execution is hard, free time is scarce. I hope I get the ball rolling though.

Step-by-Step Guide to Building a Generative AI Model from Scratch

Generative AI is a cutting-edge technology that creates content such as text, images, or even music. Building a generative AI model may seem challenging, but with the right steps, anyone can understand the process. Let’s explore steps to build a generative AI model from scratch.

1. Understand Generative AI Basics

Before starting, understand what generative AI does. Unlike traditional AI models that predict or classify, generative AI creates new data based on patterns it has learned. Popular examples include ChatGPT and DALL·E.

2. Define Your Goal

Identify what you want your model to generate. Is it text, images, or something else? Clearly defining the goal helps in choosing the right algorithms and tools.

Example goals:

Writing stories or articles

Generating realistic images

Creating music

3. Choose the Right Framework and Tools

To build your AI model, you need tools and frameworks. Some popular ones are:

TensorFlow: Great for complex AI models.

PyTorch: Preferred for research and flexibility.

Hugging Face: Ideal for natural language processing (NLP).

Additionally, you'll need programming knowledge, preferably in Python.

4. Collect and Prepare Data

Data is the backbone of generative AI. Your model learns patterns from this data.

Collect Data: Gather datasets relevant to your goal. For instance, use text datasets for NLP models or image datasets for generating pictures.

Clean the Data: Remove errors, duplicates, and irrelevant information.

Label Data (if needed): Ensure the data has proper labels for supervised learning tasks.

You can find free datasets on platforms like Kaggle or Google Dataset Search.

5. Select a Model Architecture

The type of generative AI model you use depends on your goal:

GANs (Generative Adversarial Networks): Good for generating realistic images.

VAEs (Variational Autoencoders): Great for creating slightly compressed data representations.

Transformers: Used for NLP tasks like text generation (e.g., GPT models).

6. Train the Model

Training involves feeding your data into the model and letting it learn patterns.

Split your data into training, validation, and testing sets.

Use GPUs or cloud services for faster training. Popular options include Google Colab, AWS, or Azure.

Monitor the training process to avoid overfitting (when the model learns too much from training data and fails with new data).

7. Evaluate the Model

Once the model is trained, test it on new data. Check for:

Accuracy: How close the outputs are to the desired results.

Creativity: For generative tasks, ensure outputs are unique and relevant.

Error Analysis: Identify areas where the model struggles.

8. Fine-Tune the Model

Improvement comes through iteration. Adjust parameters, add more data, or refine the model's architecture to enhance performance. Fine-tuning is essential for better outputs.

9. Deploy the Model

Once satisfied with the model’s performance, deploy it to real-world applications. Tools like Docker or cloud platforms such as AWS and Azure make deployment easier.

10. Maintain and Update the Model

After deployment, monitor the model’s performance. Over time, update it with new data to keep it relevant and efficient.

Conclusion

Building a generative AI model from scratch is an exciting journey that combines creativity and technology. By following this step-by-step guide, you can create a powerful model tailored to your needs, whether it's for generating text, images, or other types of content.

If you're looking to bring your generative AI idea to life, partnering with a custom AI software development company can make the process seamless and efficient.

Podman for Beginners: Understanding Rootless Containers

In the fast-evolving world of containerization, Podman has emerged as a powerful, user-friendly, and secure alternative to Docker. One of its standout features is the support for rootless containers, which allows users to run containers without requiring elevated privileges. If you're new to Podman and curious about rootless containers, this guide is for you.

What is Podman?

Podman (Pod Manager) is an open-source container engine that enables users to create, manage, and run containers and pods. Unlike Docker, Podman operates without a central daemon, which enhances its security and flexibility.

What Are Rootless Containers?

Rootless containers allow users to run containers as non-root users. This significantly reduces security risks, as it minimizes the impact of potential vulnerabilities within containers. With rootless containers, even if a container is compromised, the damage is limited to the privileges of the user running it.

Benefits of Rootless Containers

Enhanced Security Rootless containers reduce the risk of privilege escalation, making them an ideal choice for running containers in development and production environments.

User-Specific Containers Each user can manage their container ecosystem independently, avoiding conflicts and ensuring isolation.

No Root Privileges Required Rootless containers eliminate the need for administrative access, making them safer for shared environments and CI/CD pipelines.

How to Get Started with Podman Rootless Containers

Step 1: Install Podman

Ensure you have Podman installed on your system. For most Linux distributions, you can install Podman using the package manager:

sudo apt install podman # For Debian-based systems sudo dnf install podman # For Fedora-based systems

Step 2: Verify Installation

Run the following command to check if Podman is installed correctly:

podman --version

Step 3: Create and Run a Rootless Container

Switch to a non-root user and run the following commands:

Pull an image:podman pull alpine

Run a container:podman run --rm -it alpine sh

This runs an Alpine Linux container in a rootless mode.

Step 4: Manage Containers

You can list running containers using:

podman ps

And stop a container using:

podman stop <container_id>

Limitations of Rootless Containers

While rootless containers are highly secure, there are some limitations:

Networking: Networking features may be restricted due to the lack of root privileges.

Performance: Certain operations may have slight performance overheads.

Compatibility: Not all container images or workloads are fully compatible with rootless containers.

When to Use Rootless Containers

Rootless containers are ideal for:

Development environments where security and isolation are essential.

CI/CD pipelines that don’t require root access.

Scenarios where multi-user isolation is necessary.

Conclusion

Podman’s rootless containers offer a seamless and secure way to work with containers, especially for users who value security and flexibility. By enabling rootless operations, Podman empowers developers to build and manage containers without compromising system integrity.
