![]() ![]() GitOps uses merge requests (MR) as a point of collaboration across teams, simultaneously providing a record for audit and troubleshooting. If disaster strikes, the latest version will be automatically redeployed. Connecting these tools to your Git repository ensures your deployed infrastructure conforms to the latest approved version. These tools keep your infrastructure configuration versioned, backed up, and reproducible from source control. You may already be using IaC tools such as Chef and Puppet that can provision servers on demand. When it comes to GitOps, there are three core principles that you need to understand: Here are some key things you should know if you're considering adopting GitOps. GitOps feeds the CI/CD pipeline, automating the delivery of the declared infrastructure to cluster(s) in development, staging, production, or other environments. Once a configuration file is committed to Git, it's the job of GitOps to deploy and maintain that configuration in the designated state. People often ask if GitOps is infrastructure-as-code (IaC) or if GitOps is CI/CD. ![]() What to keep in mind if you're considering GitOps It's simple to find out “what changed?” because everyone can go directly to the answer. Git tracks everything, making repeatability easy. GitOps helps organizations enforce security best practices and provides audit trails that identify the details of infrastructure changes (such as authorship and origin, deployment date and time, and affected resources). This results in faster, more frequent deployments. ![]() GitOps workflows provide a convenient audit log of all cluster changes in the Git repository, allowing you to audit changes and roll back to the previous state if necessary.Ĭontinuous deployment of source-controlled infrastructure reduces configuration errors, saving time for DevOps teams and allowing multiple teams to work on different infrastructure components without interfering with each other’s work. If you're deploying the same applications across multiple clusters, GitOps can ensure that all clusters are identical, without the errors that are common with manual operations. Incorporating infrastructure configuration updates in the CI/CD pipeline allows application and infrastructure changes to occur in lockstep, reducing configuration errors. GitOps automates the management of infrastructure as a part of your DevOps practice. The major advantage of GitOps is that it provides a single consistent model for making changes to infrastructure, applications, Kubernetes, and Kubernetes add-ons. Teams reduce time spent on provisioning and managing infrastructure resources, and can prioritize proactive delivery of additional services and capabilities. Once a change is triggered in Git by a developer, it's applied throughout the environment with little or no involvement from operations. Applying GitOps principles can simplify the developer experience for declarative infrastructure and provide a central point of coordination that streamlines collaboration, CI/CD, version control, code review, and configuration management. Process automation is one of the essential components of efficient DevOps, making GitOps a natural addition. Essentially, GitOps enables self-service for Dev, while using well-understood Git capabilities to ensure that everything is properly reviewed, logged, and audited. Using GitOps, developers can deploy new code (and the infrastructure configuration necessary to support that code) without waiting for anyone in Dev to make it happen. Configuration files are pushed to the infrastructure (or pulled by the infrastructure) in a coordinated manner along with application files, ensuring that the infrastructure is correctly configured. A Git repository-such as GitHub, GitLab, or a private Git repository-serves as the single source of truth for infrastructure running in development, staging, production, etc. With the GitOps approach, Git is used to version and store the necessary infrastructure configuration files. ![]() Applying GitOps principles to your operations brings the benefits of Git to infrastructure management and deployment pipelines. Expanding on this basic GitOps definition, GitOps simplifies the management of cloud native infrastructure by applying the Git best practices from software development to infrastructure configuration, using an infrastructure-as-code (IaC) approach. GitOps is an operational model that applies the principles of Git-an open source version control system-to infrastructure configuration. ![]()
