HYPERFLEET-1218 - chore: remove helm-git plugin from E2E image#158ciaranRoche wants to merge 1 commit into
Conversation
Remove helm-git plugin installation from Dockerfile. E2E tests use local chart paths (helm upgrade --install <chart-dir>) and do not require helm-git plugin for chart consumption. HyperFleet charts migrated to OCI distribution (HYPERFLEET-1216).

WalkthroughThe Dockerfile no longer declares Estimated code review effort: 1 (Trivial) | ~2 minutes Merge Risk: 🟠 High · up to The image build still installs a Helm plugin from a mutable Git reference, allowing changed or compromised upstream content to enter the E2E image.

Helm 3 plugin install --version semantics helm-diff GitHub release source
💡 Result:
To install a specific version of a Helm plugin like helm-diff from GitHub using the --version flag, you can use the following command structure: helm plugin install https://github.com/databus23/helm-diff --version v3.15.7 Key points regarding this process include: 1. Version Syntax: The --version flag supports Semantic Versioning (SemVer 2) [1][2]. When provided, Helm uses this to target the corresponding tag in the remote version control system (VCS) repository [1][3]. 2. Plugin Compatibility: While the --version flag works well for many plugins [3], some newer Helm environments (notably Helm 4) may impose stricter verification requirements or changes to plugin installation workflows [4][5]. If you encounter verification errors (e.g., missing.prov files), common workarounds include using --verify=false [6][5] or manually downloading the release archive (e.g.,.tgz) from the GitHub releases page and installing it from the local file path [7][4][5]. 3. Verification: By default, Helm verifies plugin signatures when installing from tarballs [6][8]. Installing directly from a GitHub VCS URL typically relies on the Git tag matching the specified --version [3]. 4. Troubleshooting: If you experience issues with conflicting plugin names or installation errors, ensure no previous versions are installed [3][9] or verify that the plugin repository is compatible with your current Helm version [7][10]. For the most reliable installation in restricted or production environments, downloading the official release artifact directly from the plugin's GitHub releases page and running helm plugin install /path/to/extracted-plugin/ is often recommended [7][5].

site:github.com/helm/helm pkg/plugin installer VCS --version git checkout helm plugin install source
💡 Result:
To install a Helm plugin from a Version Control System (VCS) like Git, you use the helm plugin install command [1][2]. Command Syntax: helm plugin install --version Key Details: 1. VCS Detection: Helm automatically detects VCS repositories (such as GitHub) if the URL is correctly formatted [3]. If you encounter a "Cannot detect VCS" error, you can force Git usage by appending.git to the repository URL (e.g., https://github.com/org/repo.git) or by using the git:// protocol [3]. 2. Versioning: Use the --version flag to specify a Git tag, branch, or commit [2]. If the --version flag is omitted, Helm will clone the default branch of the repository [4][5]. 3. Mechanism: When a version is specified, the Helm plugin installer performs a git clone of the repository and executes a git checkout for the requested version [5]. 4. Best Practices: Always ensure the URL points to the root of the repository. If you are behind an internal proxy or using a non-standard VCS host, explicit.git suffixes or protocol prefixes are often required for successful detection [3]. For further assistance, you can run helm plugin install --help to view the specific options available in your installed version of Helm [1][6].

Pin the Helm plugin to immutable content.
--version ${HELM_DIFF_VERSION} checks out a Git ref. It does not verify the commit or artifact checksum. A moved tag or compromised repository can inject plugin code during the image build (CWE-494, CWE-829). Use a reviewed commit SHA or a release artifact with a verified checksum or signature.

What
Remove helm-git plugin installation from E2E Dockerfile.
Changes
Why
E2E tests use local chart paths via filesystem. No helm-git plugin needed.
HyperFleet charts now published to OCI registry (HYPERFLEET-1216). Plugin not required for OCI consumption.
Testing
E2E Dockerfile builds successfully without helm-git plugin.
