DryRun Security Summary

The GitHub Actions workflows were updated to improve security and reliability by implementing SHA pinning, defining specific triggered events, and automating the Helm chart release process with pinned dependency versions.

Summary:

The provided code changes focus on improving the security and reliability of the GitHub Actions (GHA) workflows used in the repository. The key changes include:

1. SHA Pinning: The .github/workflows/gha-pin.yml workflow uses the suzuki-shunsuke/pinact-action GitHub Action to check the SHA pins of the GitHub Actions used in the workflow. This helps ensure that the specific versions of the actions are used, reducing the risk of unintended changes or potential security vulnerabilities.

2. Triggered Events: The .github/workflows/gha-pin.yml workflow is triggered on three events: workflow_dispatch (manual trigger), push, and pull_request. This ensures that the SHA pin check is performed whenever changes are made to the repository.

3. Helm Chart Release Process: The .github/workflows/release-x-manual-helm-chart.yml workflow automates the release process for a Helm chart. It includes steps to update the Docker image tag in the Helm chart values, create a new GitHub release with the packaged Helm chart, and update the Helm repository index file. The workflow also pins the versions of the dependencies used, such as the "azure/setup-helm" and "mikefarah/yq" actions.

These changes demonstrate a strong focus on security and reliability, ensuring that the GitHub Actions used in the repository are well-managed and the Helm chart release process is secure and automated.

Files Changed:

1. .github/workflows/gha-pin.yml: This workflow checks the SHA pins of the GitHub Actions used in the repository, helping to maintain the integrity of the actions and reduce the risk of security vulnerabilities.

2. .github/workflows/release-x-manual-helm-chart.yml: This workflow automates the release process for a Helm chart, including steps to update the Docker image tag, create a new GitHub release, and update the Helm repository index file. The workflow also pins the versions of the dependencies used, improving security and reliability.
