Helm charts¶
Helm charts are packages that define, install, and upgrade Kubernetes applications.^[400-devops-04-ci-cd-pipelines-helm.md]
Components and Usage¶
A Helm chart typically includes a values file that allows users to override default configurations.^[400-devops-04-ci-cd-pipelines-helm.md] For example, when deploying a database like MySQL, users can retrieve the chart using a pull command (e.g., helm pull) and then customize the deployment by overwriting these specific values.^[400-devops-04-ci-cd-pipelines-helm.md]
Prerequisites¶
Utilizing Helm charts effectively requires a pre-existing containerization environment.^[400-devops-04-ci-cd-pipelines-helm.md] Specifically, [[Docker]] must be installed and configured on the system before proceeding with Helm operations.^[400-devops-04-ci-cd-pipelines-helm.md]
Distribution¶
Charts are often distributed and discovered through centralized repositories.^[400-devops-04-ci-cd-pipelines-helm.md] A primary public registry for finding and sharing these packages is the Artifact Hub.^[400-devops-04-ci-cd-pipelines-helm.md]
