[i-love-linux-and-reject-gender]

I've had a semi irrational fear of continer software (docker, cubernates etc) for a while, and none of my self hosting needs have needed more than a one off docker setup occasionally but i always ditch it fairly quickly. Any reason to use kubernates you wanna soap box about? (Features, use cases, stuff u've used it for, anything)

the main reasons why i like Kubernetes are the same reasons why i like NixOS (my Kubernetes addiction started before my NixOS journey)

both are declarative, reproducible and solve dependency hell

i will separate this a bit,

advantages of container technologies (both plain docker but also kubernetes):

every container is self-contained which solves dependency problems and "works on my machine" problems. you can move a docker container from one computer to another and as long as the container version and the mounted files stay the same and it will behave in the same way

advantages of docker-compose and kubernetes:

declarativeness. the standard way of spinning up a container with `docker run image:tag` is in my opinion an anti pattern and should be avoided. it makes updating the container difficult and more painful than it needs to be. instead docker compose allows you to write a yaml file instead which configures your container. like this:

```

version: "3"

services:

myService:

image: "image:tag"

```

you can then start up the container with this config with `docker compose up`. with this you can save the setup for all your docker containers in config files. this already makes your setup quite portable which is very cool. it increases your reliability by quite a bit since you only need to run `docker compose up -d` to configure everything for an application. when you also have the config files for that application stored somewhere it's even better.

kubernetes goes even further. this is what a simple container deployment looks like: (i cut out some stuff, this isn't enough to even expose this app)

this sure is a lot of boilerplate, and it can get much worse. but this is very powerful when you want to make everything on your server declarative.

for example, my grafana storage is not persistent, which means whenever i restart my grafana container, all config data gets lost. however, i am storing my dashboards in git and have SSO set up, so kubernetes automatically adds the dashboards from git

the main point why i love kubernetes so much is the combination of a CI/CD pipeline with a declarative setup.

there is a software called ArgoCD which can read your kubernetes config files from git, check if the ones that you are currently using are identical to the ones in git and automatically applies the state from git to your kubernetes.

i completely forgot to explain of the main features of kubernetes:

kubernetes is a clustered software, you can use one or two or three or 100 computers together with it and use your entire fleet of computers as one unit with kubernetes. i have currently 3 machines and i don't even decide which machine runs which container, kubernetes decides that for me and automatically maintains a good resource spread. this can also protect from computer failures, if one computer fails, the containers just get moved to another host and you barely use any uptime. this works even better with clustered storage, where copies of your data are distributed around your cluster. this is also useful for updates, as you can easily reboot a server for updates without causing any downtime.

also another interesting design pattern is the architecture of how containers are managed. to create a new container, you usually create a deployment, which is a higher-level resource than a container and which creates containers for you. and the deployment will always make sure that there are enough containers running so the deployment specifications are met. therefore, to restart a container in kubernetes, you often delete it and let the deployment create a new one.

so for use cases, it is mostly useful if you have multiple machines. however i have run kubernetes on a singular machine multiple times, the api and config is just faaaaaaar too convenient for me. you can run anything that can run in docker on kubernetes, which is (almost) everything. kubernetes is kind of a data center operating system, it makes stuff which would require a lot of manual steps obsolete and saves ops people a lot of time. i am managing ~150 containers with one interface with ease. and that amount will grow even more in the future lol

i hope this is what you wanted, this came straight from my kubernetes-obsessed brain. hope this isn't too rambly or annoying

it miiiiiiiight be possible to tell that this is my main interest lol

Microsoft Azure Fundamentals AI-900 (Part 5)

Microsoft Azure AI Fundamentals: Explore visual studio tools for machine learning

What is machine learning? A technique that uses math and statistics to create models that predict unknown values

Types of Machine learning

Regression - predict a continuous value, like a price, a sales total, a measure, etc

Classification - determine a class label.

Clustering - determine labels by grouping similar information into label groups

x = features

y = label

Azure Machine Learning Studio

You can use the workspace to develop solutions with the Azure ML service on the web portal or with developer tools

Web portal for ML solutions in Sure

Capabilities for preparing data, training models, publishing and monitoring a service.

First step assign a workspace to a studio.

Compute targets are cloud-based resources which can run model training and data exploration processes

Compute Instances - Development workstations that data scientists can use to work with data and models

Compute Clusters - Scalable clusters of VMs for on demand processing of experiment code

Inference Clusters - Deployment targets for predictive services that use your trained models

Attached Compute - Links to existing Azure compute resources like VMs or Azure data brick clusters

What is Azure Automated Machine Learning

Jobs have multiple settings

Provide information needed to specify your training scripts, compute target and Azure ML environment and run a training job

Understand the AutoML Process

ML model must be trained with existing data

Data scientists spend lots of time pre-processing and selecting data

This is time consuming and often makes inefficient use of expensive compute hardware

In Azure ML data for model training and other operations are encapsulated in a data set.

You create your own dataset.

Classification (predicting categories or classes)

Regression (predicting numeric values)

Time series forecasting (predicting numeric values at a future point in time)

After part of the data is used to train a model, then the rest of the data is used to iteratively test or cross validate the model

The metric is calculated by comparing the actual known label or value with the predicted one

Difference between the actual known and predicted is known as residuals; they indicate amount of error in the model.

Root Mean Squared Error (RMSE) is a performance metric. The smaller the value, the more accurate the model’s prediction is

Normalized root mean squared error (NRMSE) standardizes the metric to be used between models which have different scales.

Shows the frequency of residual value ranges.

Residuals represents variance between predicted and true values that can’t be explained by the model, errors

Most frequently occurring residual values (errors) should be clustered around zero.

You want small errors with fewer errors at the extreme ends of the sale

Should show a diagonal trend where the predicted value correlates closely with the true value

Dotted line shows a perfect model’s performance

The closer to the line of your model’s average predicted value to the dotted, the better.

Services can be deployed as an Azure Container Instance (ACI) or to a Azure Kubernetes Service (AKS) cluster

For production AKS is recommended.

Identify regression machine learning scenarios

Regression is a form of ML

Understands the relationships between variables to predict a desired outcome

Predicts a numeric label or outcome base on variables (features)

Regression is an example of supervised ML

What is Azure Machine Learning designer

Allow you to organize, manage, and reuse complex ML workflows across projects and users

Pipelines start with the dataset you want to use to train the model

Each time you run a pipelines, the context(history) is stored as a pipeline job

Encapsulates one step in a machine learning pipeline.

Like a function in programming

In a pipeline project, you access data assets and components from the Asset Library tab

You can create data assets on the data tab from local files, web files, open at a sets, and a datastore

Data assets appear in the Asset Library

Azure ML job executes a task against a specified compute  target.

Jobs allow systematic tracking of your ML experiments and workflows.

Understand steps for regression

To train a regression model, your data set needs to include historic features and known label values.

Use the designer’s Score Model component to generate the predicted class label value

Connect all the components that will run in the experiment

Average difference between predicted and true values

It is based on the same unit as the label

The lower the value is the better the model is predicting

The square root of the mean squared difference between predicted and true values

Metric based on the same unit as the label.

A larger difference indicates greater variance in the individual  label errors

Relative metric between 0 and 1 on the square based on the square of the differences between predicted and true values

Closer to 0 means the better the model is performing.

Since the value is relative, it can compare different models with different label units

Relative metric between 0 and 1 on the square based on the absolute of the differences between predicted and true values

Closer to 0 means the better the model is performing.

Can be used to compare models where the labels are in different units

Also known as R-squared

Summarizes how much variance exists between predicted and true values

Closer to 1 means the model is performing better

Remove training components form your data and replace it with a web service inputs and outputs to handle the web requests

It does the same data transformations as the first pipeline for new data

It then uses trained model to infer/predict label values based on the features.

Create a classification model with Azure ML designer

Classification is a form of ML used to predict which category an item belongs to

Like regression this is a supervised ML technique.

Understand steps for classification

True Positive - Model predicts the label and the label is correct

False Positive - Model predicts wrong label and the data has the label

False Negative - Model predicts the wrong label, and the data does have the label

True Negative - Model predicts the label correctly and the data has the label

For multi-class classification, same approach is used. A model with 3 possible results would have a 3x3 matrix.

Diagonal lien of cells were the predicted and actual labels match

Number of cases classified as positive that are actually positive

True positives divided by (true positives + false positives)

Fraction of positive cases correctly identified

Number of true positives divided by (true positives + false negatives)

Overall metric that essentially combines precision and recall

Classification models predict probability for each possible class

For binary classification models, the probability is between 0 and 1

Setting the threshold can define when a value is interpreted as 0 or 1.  If its set to 0.5 then 0.5-1.0 is 1 and 0.0-0.4 is 0

Recall also known as True Positive Rate

Has a corresponding False Positive Rate

Plotting these two metrics on a graph for all values between 0 and 1 provides information.

Receiver Operating Characteristic (ROC) is the curve.

In a perfect model, this curve would be high to the top left

Area under the curve (AUC).

Remove training components form your data and replace it with a web service inputs and outputs to handle the web requests

It does the same data transformations as the first pipeline for new data

It then uses trained model to infer/predict label values based on the features.

Create a Clustering model with Azure ML designer

Clustering is used to group similar objects together based on features.

Clustering is an example of unsupervised learning, you train a model to just separate items based on their features.

Understanding steps for clustering

Prebuilt components exist that allow you to clean the data, normalize it, join tables and more

Requires a dataset that includes multiple observations of the items you want to cluster

Requires numeric features that can be used to determine similarities between individual cases

Initializing K coordinates as randomly selected points called centroids in an n-dimensional space (n is the number of dimensions in the feature vectors)

Plotting feature vectors as points in the same space and assigns a value how close they are to the closes centroid

Moving the centroids to the middle points allocated to it (mean distance)

Reassigning to the closes centroids after the move

Repeating the last two steps until tone.

Maximum distances between each point and the centroid of that point’s cluster.

If the value is high it can mean that cluster is widely dispersed.

With the Average Distance to Closer Center, we can determine how spread out the cluster is

Remove training components form your data and replace it with a web service inputs and outputs to handle the web requests

It does the same data transformations as the first pipeline for new data

It then uses trained model to infer/predict label values based on the features.

Kubernetes with HELM: Kubernetes for Absolute Beginners

Welcome to the world of Kubernetes with HELM: Kubernetes for Absolute Beginners! If you're new to Kubernetes, Helm, or both, you’re in the right place. Kubernetes, often referred to as K8s, is a game-changer in the tech world. It helps automate the deployment, scaling, and management of containerized applications. Meanwhile, Helm, often called the "Kubernetes Package Manager," simplifies your life by making it easier to manage Kubernetes applications. Together, these tools provide a powerful foundation for building, deploying, and managing modern applications.

But don’t worry if all of this sounds a bit overwhelming right now! This blog is designed for absolute beginners, so we’ll break everything down in simple, easy-to-understand terms.

What is Kubernetes?

In simple words, Kubernetes is an open-source platform that automates the deployment and scaling of containerized applications. Think of it as an organizer for your containers. When you have an app that’s broken down into multiple containers, Kubernetes takes care of how they’re connected, how they communicate, and how they scale.

Imagine you have a business with multiple stores (containers). Kubernetes makes sure that each store operates efficiently, knows how to communicate with others, and can expand or reduce operations based on customer demand, without needing constant manual attention. That’s the kind of magic Kubernetes brings to the world of software.

What is Helm?

Now that we’ve introduced Kubernetes, let’s talk about Helm. In the simplest terms, Helm is a package manager for Kubernetes. It’s like a toolbox that helps you manage your Kubernetes applications more easily.

Helm uses something called "charts." These Helm charts are basically packages that contain all the configuration files you need to run an application in Kubernetes. With Helm, you can deploy applications with just a few commands, manage upgrades, and even roll back to previous versions if something goes wrong. It’s like hitting the "easy button" for Kubernetes.

2. Install Helm

Once you have Kubernetes set up, it’s time to install Helm.

Download Helm from the official website.

Install Helm using your package manager (like Homebrew on macOS or Chocolatey on Windows).

Initialize Helm in your Kubernetes cluster.

It’s that simple! You’re now ready to use Helm with Kubernetes.

Deploying Your First Application with Helm

Now that you have both Kubernetes and Helm set up, it’s time to deploy your first application.

Choose a Helm Chart: Helm charts are packages that define the Kubernetes resources for an application. You can either use pre-built charts or create your own.

Install the Chart: Once you have your chart, installing it is as easy as running a single command. Helm will handle the rest.

Manage and Monitor: Helm makes it easy to monitor your app, make updates, and roll back changes if necessary.

For example, you can deploy a simple web server using a Helm chart by typing:

bash

Copy code

helm install my-nginx bitnami/nginx

With that one command, you’ll have a fully functioning Nginx web server running in Kubernetes!

New GKE Ray Operator on Kubernetes Engine Boost Ray Output

GKE Ray Operator

The field of AI is always changing. Larger and more complicated models are the result of recent advances in generative AI in particular, which forces businesses to efficiently divide work among more machines. Utilizing Google Kubernetes Engine (GKE), Google Cloud’s managed container orchestration service, in conjunction with ray.io, an open-source platform for distributed AI/ML workloads, is one effective strategy. You can now enable declarative APIs to manage Ray clusters on GKE with a single configuration option, making that pattern incredibly simple to implement!

Ray offers a straightforward API for smoothly distributing and parallelizing machine learning activities, while GKE offers an adaptable and scalable infrastructure platform that streamlines resource management and application management. For creating, implementing, and maintaining Ray applications, GKE and Ray work together to provide scalability, fault tolerance, and user-friendliness. Moreover, the integrated Ray Operator on GKE streamlines the initial configuration and directs customers toward optimal procedures for utilizing Ray in a production setting. Its integrated support for cloud logging and cloud monitoring improves the observability of your Ray applications on GKE, and it is designed with day-2 operations in mind.

- Advertisement -

Getting started

When establishing a new GKE Cluster in the Google Cloud dashboard, make sure to check the “Enable Ray Operator” function. This is located under “AI and Machine Learning” under “Advanced Settings” on a GKE Autopilot Cluster.

The Enable Ray Operator feature checkbox is located under “AI and Machine Learning” in the “Features” menu of a Standard Cluster.

You can set an addons flag in the following ways to utilize the gcloud CLI:

gcloud container clusters create CLUSTER_NAME \ — cluster-version=VERSION \ — addons=RayOperator

- Advertisement -

GKE hosts and controls the Ray Operator on your behalf after it is enabled. After a cluster is created, your cluster will be prepared to run Ray applications and build other Ray clusters.

Record-keeping and observation

When implementing Ray in a production environment, efficient logging and metrics are crucial. Optional capabilities of the GKE Ray Operator allow for the automated gathering of logs and data, which are then seamlessly stored in Cloud Logging and Cloud Monitoring for convenient access and analysis.

When log collection is enabled, all logs from the Ray cluster Head node and Worker nodes are automatically collected and saved in Cloud Logging. The generated logs are kept safe and easily accessible even in the event of an unintentional or intentional shutdown of the Ray cluster thanks to this functionality, which centralizes log aggregation across all of your Ray clusters.

By using Managed Service for Prometheus, GKE may enable metrics collection and capture all system metrics exported by Ray. System metrics are essential for tracking the effectiveness of your resources and promptly finding problems. This thorough visibility is especially important when working with costly hardware like GPUs. You can easily construct dashboards and set up alerts with Cloud Monitoring, which will keep you updated on the condition of your Ray resources.

TPU assistance

Large machine learning model training and inference are significantly accelerated using Tensor Processing Units (TPUs), which are custom-built hardware accelerators. Ray and TPUs may be easily used with its AI Hypercomputer architecture to scale your high-performance ML applications with ease.

By adding the required TPU environment variables for frameworks like JAX and controlling admission webhooks for TPU Pod scheduling, the GKE Ray Operator simplifies TPU integration. Additionally, autoscaling for Ray clusters with one host or many hosts is supported.

Reduce the delay at startup

When operating AI workloads in production, it is imperative to minimize start-up delay in order to maximize the utilization of expensive hardware accelerators and ensure availability. When used with other GKE functions, the GKE Ray Operator can significantly shorten this startup time.

You can achieve significant speed gains in pulling images for your Ray clusters by hosting your Ray images on Artifact Registry and turning on image streaming. Huge dependencies, which are frequently required for machine learning, can lead to large, cumbersome container images that take a long time to pull. For additional information, see Use Image streaming to pull container images. Image streaming can drastically reduce this image pull time.

Moreover, model weights or container images can be preloaded onto new nodes using GKE secondary boot drives. When paired with picture streaming, this feature can let your Ray apps launch up to 29 times faster, making better use of your hardware accelerators.

Scale Ray is currently being produced

A platform that grows with your workloads and provides a simplified Pythonic experience that your AI developers are accustomed to is necessary to stay up with the quick advances in AI. This potent trifecta of usability, scalability, and dependability is delivered by Ray on GKE. It’s now simpler than ever to get started and put best practices for growing Ray in production into reality with the GKE Ray Operator.

Best Practices for Deploying Kubernetes in Production Environments

Kubernetes has emerged as the go-to solution for container orchestration, enabling organizations to efficiently manage, scale, and deploy containerized applications. Whether you're deploying Kubernetes in the cloud or on-premises, following best practices is essential to ensuring a smooth, scalable, and secure production environment. In this blog, we'll explore the key best practices for deploying Kubernetes in production and how these practices can help businesses optimize their infrastructure.

We'll also touch upon the "Docker Swarm vs Kubernetes" debate to highlight why Kubernetes is often the preferred choice for large-scale production environments.

1. Plan for Scalability from Day One

One of the main reasons companies adopt Kubernetes is its ability to scale applications seamlessly. To take full advantage of this feature, it’s important to design your architecture with scalability in mind from the beginning.

Cluster Size: Initially, it might be tempting to start with a smaller cluster. However, it’s a good idea to think ahead and choose an appropriate cluster size that can handle both current and future workloads. Use node autoscaling to dynamically adjust your cluster size based on demand.

Resource Requests and Limits: Properly configure resource requests and limits for CPU and memory for each pod. This ensures that your application can handle increased workloads without overwhelming the cluster or causing bottlenecks.

By following these scalability practices, you can ensure your Kubernetes environment is built to grow as your business and application demands increase.

2. Use Namespaces to Organize Resources

Namespaces are essential for organizing resources in a Kubernetes cluster. They allow you to logically divide your cluster based on environments (e.g., development, staging, and production) or teams.

Separation of Concerns: Using namespaces, you can separate concerns and prevent different teams or environments from affecting each other.

Resource Quotas: Kubernetes allows you to set resource quotas per namespace, ensuring no single namespace consumes all available resources. This is particularly helpful when managing multiple teams or projects on the same cluster.

Network Policies: Network policies can be configured per namespace to ensure secure communication between different services within a namespace and restrict unwanted access from other namespaces.

Implementing namespaces effectively will help maintain order within your Kubernetes cluster, making it easier to manage and scale.

3. Automate Everything with CI/CD Pipelines

Continuous Integration and Continuous Deployment (CI/CD) pipelines are crucial for deploying updates efficiently and consistently. Automation not only reduces the chance of human error but also speeds up deployment processes.

Integration with Kubernetes: Your CI/CD pipeline should be able to automate Kubernetes deployments, ensuring that any changes made to the application or infrastructure are automatically reflected in the cluster.

Helm Charts: Use Helm charts to package, manage, and deploy Kubernetes applications. Helm makes it easier to automate deployments by allowing you to define, version, and share application configurations.

Rollbacks: Ensure that your CI/CD pipeline has a rollback mechanism in place. If an update fails or introduces issues, a rollback feature can quickly revert your environment to a previous stable version.

Automation ensures that your Kubernetes environment is always up-to-date and that any new code is deployed with minimal manual intervention.

4. Prioritize Security

Security in a Kubernetes production environment should be a top priority. Kubernetes has multiple layers of security that need to be configured correctly to avoid vulnerabilities.

Role-Based Access Control (RBAC): RBAC is essential for limiting what users and service accounts can do within your cluster. Ensure that you’re using the principle of least privilege by granting users the minimal permissions they need to do their job.

Secrets Management: Use Kubernetes Secrets to store sensitive information, such as passwords and API keys, securely. Ensure that your Secrets are encrypted at rest.

Pod Security Policies (PSPs): Enable Pod Security Policies to control the security settings of your pods. This can help prevent privilege escalation, limit the capabilities of your containers, and define safe deployment practices.

Network Security: Use network policies to restrict traffic between pods. By default, all pods in Kubernetes can communicate with each other, but you can create rules that control which pods are allowed to communicate and which aren’t.

Implementing these security measures from the start ensures that your Kubernetes cluster is resilient against potential threats and attacks.

5. Optimize Resource Usage

Efficient resource utilization is crucial to running Kubernetes cost-effectively, especially in a production environment.

Horizontal Pod Autoscaling (HPA): Use HPA to automatically adjust the number of pods in a deployment based on CPU utilization or other custom metrics. This allows your application to handle varying loads without manually scaling resources.

Vertical Pod Autoscaling (VPA): While HPA scales the number of pods, VPA adjusts the CPU and memory limits for individual pods. This ensures that your application is always running with optimal resources based on its current workload.

Cluster Autoscaler: Enable Cluster Autoscaler to automatically add or remove nodes from the cluster depending on the resource requirements of your pods. This helps in managing costs by ensuring that you’re not running unnecessary nodes during low traffic periods.

Optimizing resource usage ensures that your infrastructure is cost-effective while still being able to handle large spikes in traffic.

6. Monitor and Log Everything

In a production environment, visibility into what’s happening in your Kubernetes cluster is vital. Proper monitoring and logging ensure that you can detect, troubleshoot, and resolve issues before they become critical.

Monitoring Tools: Use tools like Prometheus and Grafana for monitoring your Kubernetes cluster. These tools can track performance metrics such as CPU, memory usage, and the health of your applications.

Logging Tools: Implement centralized logging using tools like Elasticsearch, Fluentd, and Kibana (EFK stack). Centralized logging helps you troubleshoot issues across multiple services and components.

Alerting: Configure alerting systems to notify your team when certain thresholds are breached or when a service fails. Early detection allows you to address problems before they affect your users.

With robust monitoring and logging in place, you can quickly detect and resolve issues, ensuring that your applications remain available and performant.

7. Use Blue-Green or Canary Deployments

When deploying new versions of your application, it’s important to minimize the risk of downtime or failed releases. Two popular strategies for achieving this in Kubernetes are Blue-Green deployments and Canary deployments.

Blue-Green Deployments: This strategy involves running two identical environments: one for production (blue) and one for testing (green). Once the new version of the application is tested in the green environment, traffic is switched over to it, ensuring zero downtime.

Canary Deployments: In a Canary deployment, a small percentage of traffic is routed to the new version of the application while the rest continues to use the previous version. If the new version works as expected, more traffic is gradually routed to it.

Both strategies reduce the risk of introducing issues into production by allowing you to test new versions before fully rolling them out.

Docker Swarm vs Kubernetes: Why Kubernetes is the Preferred Choice for Production

While Docker Swarm provides a simpler setup and is easier for smaller deployments, Kubernetes has become the preferred solution for large-scale production environments. Kubernetes offers greater flexibility, better scalability, and a more robust ecosystem of tools and plugins. Features like horizontal autoscaling, advanced networking, and better handling of stateful applications give Kubernetes a significant advantage over Docker Swarm.

By following these best practices, businesses can ensure that their Kubernetes production environments are secure, scalable, and efficient. Whether you're just starting with Kubernetes or looking to optimize your existing setup, the right approach will save time, reduce costs, and improve the overall performance of your applications.
