Add the --server-side flag to , matching helm v4's upgrade command. The flag accepts "true", "false", or "auto" (default "auto") and is forwarded to helm when running Helm v4: - (HELM_DIFF_USE_UPGRADE_DRY_RUN=true): all values including "auto" are forwarded. - : only "true"/"false" are forwarded, since template registers --server-side as a bool (default true) that does not accept "auto". The flag is Helm v4 only — it is accepted but not forwarded when running Helm v3 (the flag does not exist there). Note: --server-side has no effect on manifest rendering in dry-run mode. It is forwarded for semantic correctness and wrapper compatibility so that helm-diff can be used with the same flags as . Closes #1020 Signed-off-by: yxxhero <aiopsclub@163.com>
The engineerd/setup-kind@v0.6.2 tag points to a commit that lacks the compiled dist/main/index.js entry point, causing all integration test jobs to fail with: File not found: '.../setup-kind/v0.6.2/dist/main/index.js' Switch to helm/kind-action@v1.14.0, the official Helm project kind action, which properly commits its build artifacts.
