Fixes#2445
The default Kubernetes client rate limiter settings were too restrictive,
causing context cancellation errors when kubedog's reflector infrastructure
tried to watch multiple resources simultaneously. When the deployment becomes
ready before the rate limiter releases the request, the context gets canceled.
This fix:
- Increases default QPS from 5 to 100 and Burst from 10 to 200
- Makes QPS and Burst configurable per release via kubedogQPS and kubedogBurst
- Uses direct client-go configuration instead of kubedog's kube.Init
- Adds comprehensive documentation and examples
Users can now tune these settings based on their cluster size and requirements:
- Small clusters: QPS=50, Burst=100
- Medium clusters: QPS=100, Burst=200 (default)
- Large clusters: QPS=200, Burst=400

This commit adds comprehensive support for Helm 4 while maintaining
full backward compatibility with Helm 3. The implementation includes:
- Updated helm version detection to support both Helm 3 and Helm 4
- Added HELMFILE_HELM4 environment variable to control Helm version
- Modified helm execution paths to handle version-specific binaries
- Updated helm plugin installation to support split architecture
- Helm 4: Uses split plugin architecture (3 separate .tgz files)
- helm-secrets.tgz
- helm-secrets-getter.tgz
- helm-secrets-post-renderer.tgz
- Helm 3: Continues using single plugin installation
- Updated Dockerfiles, CI workflows, and core installation code
- Helm 4 requires post-renderers to be plugins, not executable scripts
- Created Helm plugin structure for integration tests
- Updated helmfile.yaml templates to dynamically select renderer type
- Added test plugins: add-cm, add-cm1, add-cm2
- Updated integration tests for Helm 3/4 compatibility
- Created Helm 4 variant expected output files
- Fixed test determinism issues (repo cleanup between iterations)
- Added version-specific output filtering for warnings/messages
- Updated workflows to test both Helm 3 and Helm 4
- Matrix testing across Helm versions
- Updated helm-diff to v3.14.0 for compatibility
- Updated README and docs with Helm 4 information
- Added migration guidance
- Updated version requirements
All changes are backward compatible - existing Helm 3 users will
see no behavior changes.
fix: update Helm 4 lint expected output to match filtered output
The grep filter removes the semver warning, so the expected output
should not include it. Updated lint-helm4 files to match the filtered
output (warning removed, no extra blank line).
