Hi, This is Venkatesh Sarivisetty and today I am going to write about a blog on a good practice that helps on on-premises/ Public/Private Clouds to do a continuous Delivery of your code and make sure GIT which acts as a single source of truth about the code.
In GitOps, the entire software delivery pipeline, from code development to production deployment, is automated and managed through Git repositories and Git-based workflows.
The basic idea behind GitOps is to treat infrastructure management and application deployment as code. This means that infrastructure configurations, deployment scripts, and application code are version-controlled in Git repositories, and changes are made through pull requests and code reviews. When a new code change is pushed to a Git repository, the GitOps pipeline automatically builds, tests, and deploys the changes to the target environment.
Here are some reasons why organizations use GitOps:
Consistent and Reliable Deployments: GitOps ensures that infrastructure configurations and application deployments are consistent across all environments, from development to production. This eliminates the risk of configuration drift and ensures that deployments are reliable and predictable.
Faster time-to-market: With Gitops, developers can push code changes to production faster and with more confidence. The automated deployment pipelines ensure that changes are tested and validated before they are deployed, reducing the risk of production issues.
Improved Collaboration: GitOps promotes collaboration between developers, operations teams, and other stakeholders by providing a single source of truth for infrastructure and application configurations. This makes it easier for teams to work together and share knowledge.
Simplified Management: By using Git as a single source of truth for infrastructure and application deployments, organizations can simplify the management of their software delivery pipelines. This reduces the complexity of managing multiple tools and technologies and makes it easier to troubleshoot issues when they arise.
How to Use GitOps
To use GitOps, Organizations need to set up a GitOps pipeline that automates the build, test and deployment of applications and infra changes. Here are the basic steps to set up a GitOps pipeline:
Create Git Repositories: Create Git repositories for infrastructure configurations, deployment scripts, and app code. These repositories will serve as the single source of truth for all changes to the software delivery pipeline.
Define infrastructure as code: Use tools like Terraform, Ansible or Kubernetes to define infrastructure as code. These configurations should be stored in Git repositories and version-controlled like any other code.
Automate the deployment pipeline: Use continuous Integration/Continuous Deployment(CI/CD) tools like Jenkins, TravisCI or GitLab CI/CD to automate the deployment pipeline. This tool should be configured to listen for changes in the Git repositories and trigger the build, test, and deployment process automatically.
Monitor and Audit changes: Use tools like Prometheus or Grafana to monitor the performance of the GitOps pipeline and audit changes to the infra and application configurations.
There are popular Continuous Delivery tools like Flux and Argo. I will post those details in my next Blog.
Thanks for reading and share you comments/suggestions :)
