Ansible Collections: Extending Ansible’s Capabilities

Ansible is a powerful automation tool used for configuration management, application deployment, and task automation. One of the key features that enhances its flexibility and extensibility is the concept of Ansible Collections. In this blog post, we'll explore what Ansible Collections are, how to create and use them, and look at some popular collections and their use cases.

Introduction to Ansible Collections

Ansible Collections are a way to package and distribute Ansible content. This content can include playbooks, roles, modules, plugins, and more. Collections allow users to organize their Ansible content and share it more easily, making it simpler to maintain and reuse.

Key Features of Ansible Collections:

Modularity: Collections break down Ansible content into modular components that can be independently developed, tested, and maintained.

Distribution: Collections can be distributed via Ansible Galaxy or private repositories, enabling easy sharing within teams or the wider Ansible community.

Versioning: Collections support versioning, allowing users to specify and depend on specific versions of a collection. How to Create and Use Collections in Your Projects

Creating and using Ansible Collections involves a few key steps. Here’s a guide to get you started:

1. Setting Up Your Collection

To create a new collection, you can use the ansible-galaxy command-line tool:

ansible-galaxy collection init my_namespace.my_collection

This command sets up a basic directory structure for your collection:

my_namespace/

└── my_collection/

├── docs/

├── plugins/

│ ├── modules/

│ ├── inventory/

│ └── ...

├── roles/

├── playbooks/

├── README.md

└── galaxy.yml

2. Adding Content to Your Collection

Populate your collection with the necessary content. For example, you can add roles, modules, and plugins under the respective directories. Update the galaxy.yml file with metadata about your collection.

3. Building and Publishing Your Collection

Once your collection is ready, you can build it using the following command:

ansible-galaxy collection build

This command creates a tarball of your collection, which you can then publish to Ansible Galaxy or a private repository:

ansible-galaxy collection publish my_namespace-my_collection-1.0.0.tar.gz

4. Using Collections in Your Projects

To use a collection in your Ansible project, specify it in your requirements.yml file:

collections:

- name: my_namespace.my_collection

version: 1.0.0

Then, install the collection using:

ansible-galaxy collection install -r requirements.yml

You can now use the content from the collection in your playbooks:--- - name: Example Playbook hosts: localhost tasks: - name: Use a module from the collection my_namespace.my_collection.my_module: param: value

Aviators Expands Collaboration with Google Cloud Developers

Aviators expand Google Cloud

Even though Google has spent a lot of money on engineering productivity over the past 20 years, until a few years ago, most of the industry did not priorities this area of study. However, as companies seek to improve the productivity of their engineering teams, this data-driven discipline has gained prominence due to the rise of remote work and the quickly changing AI landscape.

Google have intimate knowledge of the difficulties (and possibilities) involved in increasing engineering efficiency because they were once employees of Google. For this reason, Cloud set out to create Aviator, an engineering productivity platform that enhances performance at every stage of the development lifecycle and assists teams in removing tedious but vital chores from their workdays.

Utilizing Google Cloud to Create a Scalable Services

Scalable Services

Building Aviator from the ground up on Google Cloud was an obvious choice, since they goal is to provide every developer with productivity engineering on par with Google. Additionally, They applied to and were accepted into the Google for Startups programme, which provides extensive credits for cloud products, business help, and technical training. This allowed our team to investigate a number of cloud possibilities without having to worry too much about price.

Google Cloud guiding principles were the main metrics that the DORA (DevOps Research and Assessment) team produced. With Google Cloud, They created a platform that provides:

Quicker and more adaptable code reviews: Automated code review guidelines, real-time reviewer input, and predetermined response time targets enhance code review cycles. With the help of these tools, developers may release code more quickly, increase the velocity of their development teams, and shorten the time it takes for code to enter production.

Stack pull requests (PRs), which are modest code changes that can be independently reviewed in a predetermined order and then synchronised to remove development bottlenecks and prevent merge conflicts, are a useful tool for accelerating review cycles.

Simplified, adaptable merging: Take command of crowded repositories with a high-throughput merge queue designed to handle thousands of pull requests while lowering out-of-date pull requests, merge conflicts, inconsistent modifications, and malfunctioning builds. Because isolated code changes are verified before being merged back into the main line of development, this increases the frequency of deployments and decreases the rate of change failures.

Shrewd release notes tailored to a service: With a single dashboard that assists teams in automatically creating release notes and managing deployments, rollbacks, and releases across all environments, you can do away with disorganized release notes and clumsy verification procedures. Development teams may provide more dependable products and systems and shorten the time it takes to recover from production failures by using the releases framework, which also increases deployment frequency and rollbacks.

Their scalable service was implemented using multiple Google Cloud products. For instance, Aviator’s architecture mainly depends on background activities to carry out automated actions. In order to scale Aviator to thousands of active users and millions of code changes, Google decided to adopt Google Kubernetes Engine (GKE). This allowed us to expand Aviators Kubernetes pods horizontally as use increased.

Furthermore, They were able to handle deployments with Google Cloud without requiring us to keep credentials on the CD platform. Additionally, They made use of the cutting-edge IAM architecture of Google Cloud to offer more flexibility in permission management.

Aviator

With these extra features, Aviator may further simplify management and collaboration for engineers by utilising Google Cloud:

Monitoring the health of the system

An open-source monitoring tool called Prometheus gathers time series data from configured targets, like applications and infrastructure, using a pull paradigm. Google were able to build up complete monitoring and alerting for Aviator without worrying about scalability or dependability thanks to Managed Service for Prometheus. In addition to our Prometheus data, Cloud Monitoring offers us access to over 6,500 free metrics that provide us a comprehensive overview of the functionality, availability, and overall health of our service in one location.

Management of logs

Aviator uses API calls as a main method of communication with external services like GitHub, PagerDuty, and Slack. Due to these services’ unreliability or network problems, these API calls frequently fail. In order to ensure that Google could quickly troubleshoot and fix any issues that are reported, They employed Google Cloud’s powerful log management features to handle this issue. This also made it simple to develop structured queries, filter the logs for various services, and even set up alarms depending on predetermined criteria.

Detection of slow queries

They picked Cloud SQL, a fully managed PostgreSQL database service from Google Cloud, for our primary database since it offers high availability and performance right out of the box. In order to identify sluggish queries on Aviator, They have been investigating query labelling with Sqlcommenter more recently.

Google can easily identify the cause of each sluggish query by using this open-source tool, which samples and tags every query. Additionally, They make use of the Python module Sqlcommenter, which works nicely with the backend of our application.

Management of rate limits

Since our team uses so many third-party services, controlling rate restrictions was essential to ensuring that our users had a continuous experience while adhering to the third-party services’ permitted limits. Furthermore, there are many APIs in Aviator itself that require rate limitations. To make monitoring and enforcing rate restrictions for both inbound and outbound API calls easier, Google Cloud used Memory store for Radis.

Cloud-based, self-hosted, and single-tenant

Because Aviator can accommodate engineering teams of any size from 20 engineers to over 2,000 installations might differ substantially. They felt that Aviator had to be able to accommodate a wide range of demands and specifications.

Currently, when configuring Aviator, a developer has the choice of choosing cloud, self-hosted, or single tenant installation. Let’s examine each in more detail:

Installation of Clouds

This version is the easiest for users to set up and is fully controlled by Aviator through a Kubernetes cluster in Google Cloud. They also perform a regular daily deployment to update it.

Independent

A self-hosted version of Aviator that they can install on their own private cloud is preferred by certain users. In this configuration, They upload new versions of the Aviator programme as Docker images to Google Cloud’s Artefact registry and publish Helm charts to a private repository.

They generate a new IAM service account with an authentication key and read-only access to the private repository where Google Cloud host our Docker images for each self-hosted customer. This account is then shared with our users. This facilitates our users’ installation of a self-hosted version of Aviator in a straightforward and safe manner.

Tenant alone

The self-hosted version and the single-tenant installation are nearly identical, with the exception that Aviator oversees the installation through our personal Google Cloud account. Users now have more flexibility over their Aviator setting and improved security as a result.

AI Research

Even more intriguing options for expanding engineering productivity have been shown by recent advances with LLMs. At Aviator, They’ve already begun investigating a number of AI-powered solutions that can help at different phases of the development lifecycle, such as:

Test generation: By using AI to create test cases on its own, developers may save a tonne of time and identify possible flaws early in the development process.

Code auto-completion: AI-powered solutions like GitHub Copilot propose code snippets in real time, helping engineers write code faster and more accurately.

Predictive test selection: AI can speed up development by lowering the number of tests run each cycle and identifying code changes that will fail tests.

Google is a leader in AI innovation with over ten years of expertise. This lets Google Cloud offer cutting-edge AI solutions like Vertex AI and Gemini. Aviator’s AI base from Google Cloud streamlines development and lets us launch next-generation AI features quickly.

In summary

More than just a performance indicator, engineering productivity is a key factor in the success of businesses. Through improved developer collaboration and efficiency, businesses may shorten time-to-market and respond faster to shifting consumer expectations. In this journey, Google Cloud has shown to be an excellent collaborator.

It is specially suited to enable quick iterations while abstracting away complexity thanks to its unique combination of dependability, speed, and performance as well as its state-of-the-art AI capabilities. At Aviator, Google Cloud are eager to keep using these technologies to increase engineering productivity to new heights.
