Review follow-ups for --allow-failed-releases (#2616): - Track per-release chart preparation failures in PrepareCharts (returned as a map keyed by release) and remove those releases from the state in Run.WithPreparedCharts when --allow-failed-releases is set, so a failed release is never executed against its original, un-prepared chart reference (which could either fail again with a duplicate error or, for charts requiring chartify, bypass patches/dependency modifications and produce an unintended result). All failures are still reported at the end via the aggregated MultiError. - Complete the release identity on error results from prepareChartForRelease so failures are attributed to the correct release. - With --allow-failed-releases, continue building dependencies of the remaining charts when 'helm dep build' fails for one release, and skip the affected releases during execution. - Wire --allow-failed-releases into 'helmfile unittest' and 'helmfile status'; remove the dead flag wiring for write-values and list (both never prepare charts, see commandsSkipChartPrep). - Simplify control flow (guard clauses, errors.As, drop dead code and redundant else branches). - Add end-to-end coverage in pkg/app/issue_2616_test.go and extend the state-level tests; document the flag in docs/cli.md and CHANGELOG.md.

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.
4: Build from source
requirements: Go
go install github.com/helmfile/helmfile@latest
Getting Started
Let's start with a simple helmfile and gradually improve it to fit your use-case!
Generate a project scaffold with best-practice directory structure:
helmfile create my-project && cd my-project
Or create a helmfile.yaml manually. 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:
