Keep Secrets Secure
Secrets in Kubernetes are digital credentials that provide authentication and authorization for various CI/CD applications and services on the Kubernetes cluster. They can be exposed through a source control system like GitHub during a CI/CD pipeline deployment. So, it is always considered a best practice to keep secrets encrypted and outside of the container for maximum security and reliability.
Implement Git-based Workflows (GitOps)
Triggering CI/CD pipelines by Git-based operations have multiple benefits in terms of collaboration and usability. All the pipeline changes and source code are stored in a unified source repository, allowing developers to review changes and eliminate errors before they are deployed.
Also, support for building snapshots and integration of chat tools (eg, Slack) provides help in tracking and recovering changes when there are failures.
