* Initial plan * Fix helmfile init not updating outdated helm plugins with Helm v4 - UpdatePlugin now handles secrets plugin with Helm 4 by using the split plugin architecture (uninstall old + install via installHelmSecretsV4) - UpdatePlugin falls back to uninstall + reinstall when helm plugin update fails (e.g., with Helm 4 or tarball-installed plugins) - Fix string-based semver comparison for helm-secrets version check in both AddPlugin and UpdatePlugin using proper semver comparison - Add helmSecretsRequiresSplitInstall helper for reuse and correctness - Add tests for update failure fallback scenarios Agent-Logs-Url: https://github.com/helmfile/helmfile/sessions/533f1b1c-dda6-4934-af27-051e4eaa9927 Co-authored-by: yxxhero <11087727+yxxhero@users.noreply.github.com> * Address reviewer feedback: preserve update error context and add version assertions in tests - exec.go: include original update error in fallback log message; wrap both errors (update + reinstall) when reinstall also fails so callers get full context - init_test.go: add semver import and GetPluginVersion assertions after CheckHelmPlugins to verify plugins are at required versions on disk Agent-Logs-Url: https://github.com/helmfile/helmfile/sessions/c784db7d-7d4c-40a0-97f0-a31eb8901cd6 Co-authored-by: yxxhero <11087727+yxxhero@users.noreply.github.com> * Address second round of reviewer feedback - exec.go: rename UpdatePlugin parameter path→repo for clarity - exec.go: fix uninstallPlugin to only emit INFO log when err == nil - exec_test.go: add Test_helmSecretsRequiresSplitInstall table-driven tests covering v4.6.9, v4.7.0, v4.8.0, v4.10.0, pre-release, invalid and empty - exec_test.go: add Test_UpdatePlugin_Helm4SecretsUsesUninstallReinstall verifying that Helm 4 + secrets uses uninstall+reinstall (not plugin update) Agent-Logs-Url: https://github.com/helmfile/helmfile/sessions/cbd3f8c9-ec7d-4500-b168-cb1c2f7c87bc Co-authored-by: yxxhero <11087727+yxxhero@users.noreply.github.com> * Add len(args) >= 3 guards in test mock for plugin update/uninstall cases Agent-Logs-Url: https://github.com/helmfile/helmfile/sessions/ea0f5afc-d52d-473b-b759-853a8f841a26 Co-authored-by: yxxhero <11087727+yxxhero@users.noreply.github.com> * Return early with combined error when uninstall fails in UpdatePlugin fallback Agent-Logs-Url: https://github.com/helmfile/helmfile/sessions/bb9a675c-309d-4b06-83d4-a6fe078dce64 Co-authored-by: yxxhero <11087727+yxxhero@users.noreply.github.com> --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: yxxhero <11087727+yxxhero@users.noreply.github.com>
Helmfile
Deploy Kubernetes Helm Charts
English | 简体中文
About
Helmfile is a declarative spec for deploying helm charts. It lets you...
- Keep a directory of chart value files and maintain changes in version control.
- Apply CI/CD to configuration changes.
- Periodically sync to avoid skew in environments.
To avoid upgrades for each iteration of helm, the helmfile executable delegates to helm - as a result, the following must be installed
Highlights
Declarative: Write, version-control, apply the desired state file for visibility and reproducibility.
Modules: Modularize common patterns of your infrastructure, distribute it via Git, S3, etc. to be reused across the entire company (See #648)
Versatility: Manage your cluster consisting of charts, kustomizations, and directories of Kubernetes resources, turning everything to Helm releases (See #673)
Patch: JSON/Strategic-Merge Patch Kubernetes resources before helm-installing, without forking upstream charts (See #673)
Status
May 2025 Update
- Helmfile v1.0 and v1.1 has been released. We recommend upgrading directly to v1.1 if you are still using v0.x.
- If you haven't already upgraded, please go over this v1 proposal here to see a small list of breaking changes.
Installation
1: Binary Installation
download one of releases
2: Package Manager
- Archlinux: install via
pacman -S helmfile - openSUSE: install via
zypper in helmfileassuming you are on Tumbleweed; if you are on Leap you must add the kubic repo for your distribution version once before that command, e.g.zypper ar https://download.opensuse.org/repositories/devel:/kubic/openSUSE_Leap_\$releasever kubic - Windows (using scoop):
scoop install helmfile - macOS (using homebrew):
brew install helmfile - Linux/macOS/Windows (using mise):
mise use -g helmfile@latest
3: Container
For more details, see run as a container
Make sure to run
helmfile initonce after installation. Helmfile uses the helm-diff plugin.
Getting Started
Let's start with a simple helmfile and gradually improve it to fit your use-case!
Suppose the helmfile.yaml representing the desired state of your helm releases looks like:
repositories:
- name: prometheus-community
url: https://prometheus-community.github.io/helm-charts
releases:
- name: prom-norbac-ubuntu
namespace: prometheus
chart: prometheus-community/prometheus
set:
- name: rbac.create
value: false
Sync your Kubernetes cluster state to the desired one by running:
helmfile apply
Congratulations! You now have your first Prometheus deployment running inside your cluster.
Iterate on the helmfile.yaml by referencing:
