GitOps applied to Kubernetes environments

GitOps applied to Kubernetes environments

GitOps employs a set of techniques to deploy infrastructure, just like how DevOps and CI/CD use techniques to deploy applications.

Today, cloud-native apps are taking over the market due to their seamless performance and enhanced efficiency. But managing complex cloud architecture is a bit difficult, even with myriads of resources in place to run them as microservices. Greater the number of microservices, the more challenges you are likely to face to keep the cloud architecture up and running.

For this issue, automation is the ultimate solution. We know Kubernetes is supported by various new management tools and technologies, but the need for robust cloud architecture still remains. 

That’s when you can use GitOps for Kubernetes!

Let’s get to know more about what GitOps is, how it works, and its overall impact on your operational workflows:

What is GitOps?

As stated above, container-based applications that run in cloud can be challenging to manage, even with a tech-giant like Kubernetes platform. 

Watch the video below to understand how is GitOps in action:

GitOps is an innovative set of practices that employs techniques from CI/CD and DevOps to simplify such cloud management. 

Key to GitOps is its ‘Infrastructure as code’ objective. Here not only the applications but their core networks and host machines are also defined in files, which can be considered as code across an automated version control system. This code is the ONLY crucial source of truth that signifies how the real-world application should look like during its production stage.

 

In short, GitOps is a new approach to CI/CD and it leverages Git as its sole ‘source of truth’ for critical applications and their underlying infrastructure. It provides complete change as well as revision control.

GitOps can be outlined as:

  • A new operating model for Kubernetes platform and cloud-native, that employs the best set of practices across deployment, monitoring, and management of container-based applications and clusters
  • Fully automated CI/CD workflows use Git for better end-to-end management, development and operations.
  • Git revision control system reviews and approves changes made to the runtime environment and infrastructure
  • A developer-centric experience for excellent application management

How GitOps works?

In GitOps, a system operates by submitting pull requests, reviewing and merging the commit, in order to match the ideal state of the system as described in a Git repository.

For Kubernetes platform, GitOps provides state-of-the-art 'infrastructure-as-code’ via declarative CD (Continuous Delivery) systems. Such a new declarative approach is what reaps maximum benefits out of the Kubernetes platform for seamless deployment, management, monitoring of Kubernetes applications.

After merging a commit, there is an automatic process that takes place in the reconciliation system of the GitOps framework. Then, this reconciliation system finalizes the ideal state to the runtime environment, as defined in Git.

GitOps framework seamlessly integrates with any CI/CD pipeline, even if it is natively managed by third-party tools. It can simplify and optimize your CI/CD workflows without actually changing the way you develop or deploy your microservices.

Also with GitOps, troubleshooting becomes quicker and easier, as it uses a pull request to solve a production issue rather than interrupting a running system.

Impact and Benefits of GitOps on Enterprises:

GitOps empowers enterprises with innovative abilities to fulfil the evolving needs to manage clustered systems and microservices.

Below given are some of the key benefits of GitOps to operations and development teams:

Better visibility

GitOps allows for better visibility, tracing, monitoring and logging so development teams can keep track of every single breaking point. This will help them address delivery problems before they even occur.

Versioned control and change management

GitOps allows for versioned deployments, thus, teams can seamlessly streamline workflows, audit them, and adapt to changes if any problems occur.

Quick Adoption

Most development teams already use Git, so they need not learn new tools or techniques, nor do they need to adapt to a whole new environment. They can easily write and deploy Git requests.

Faster Development

GitOps uses Git with best practices to quickly and easily manage features and upgrades to the Kubernetes platform. This helps enterprises with faster deployments, so they can be more agile and fulfill customer demands faster than the competition.

Better Ops

GitOps provides one model for a complete end-to-end pipeline across an enterprise. 

It drives your CI/CD (Continuous Integrations/Continuous Deployments) pipelines through pull requests. Plus, it is also able to completely reproduce your operations tasks using Git. So, all add-on changes to your applications, infrastructure, and Kubernetes are manageable through one robust GitOps model.

Robust Security

Git features robust security, powered by strong cryptography to trace down and manage changes across the platform. Moreover, it can also sign changes to prove origin and authority, thereby enhancing the security of the desired state of the cluster.

GitOps allows for better incident response, as it uses a single immutable ‘source of truth’ to produce a new system in case of a security breach. This new system is completely independent of the breached one, thus preventing downtime.

Improves Productivity

Development teams can easily update or make changes to applications that run in live production. This saves a lot of time that developers generally take to roll out updates.

Aids Audits and Compliance

Compliance and auditing become much easier, as cluster changes are securely tracked and logged in Git. The use of Git makes it easier to track down every single action of a commit. Thus, DevOps teams can quickly trace down the root cause of a problem that has occurred. Teams can meet SOC 2 compliance, as they get hold of a complete audit log of which changes were made by whom to your cluster.

 

Why CloudMatos?

CloudMatos leverages best GitOps practices to help organizations with faster and seamless deployments, management, and monitoring of Kubernetes applications.
