* feat: support Helm 4 --rollback-on-failure alongside deprecated --atomic (#2712) Helm 4 renamed the `--atomic` flag to `--rollback-on-failure` (helm/helm#13629). The old flag still works under Helm 4 but is deprecated (prints a warning) and slated for removal in Helm 5. Add a `rollbackOnFailure` key to both `helmDefaults` (HelmSpec) and `releases[]` (ReleaseSpec) that emits `--rollback-on-failure`. It requires Helm 4+ (errors otherwise) and is mutually exclusive with `atomic`. Additionally, when the resolved Helm binary is v4+, an existing `atomic: true` now emits `--rollback-on-failure` instead of `--atomic`, so users are migrated off the deprecated flag automatically without any config change. On older Helm, `atomic: true` continues to emit `--atomic`. Updated the spew-based values-ID hashes in temp_test.go that change whenever ReleaseSpec gains a field (same approach as the --force-conflicts change in #2480). Closes #2712. Signed-off-by: yxxhero <aiopsclub@163.com> * test: add integration test for rollback-on-failure / atomic migration (#2712) Covers the end-to-end plumbing that unit tests cannot (real helm version detection + cluster deploy) via test/integration/run.sh: 1. atomic: true parses, deploys a ConfigMap, and emits the version-correct flag: --rollback-on-failure on Helm 4 (auto-migration of the deprecated --atomic) and --atomic on Helm 3. 2. rollbackOnFailure: true emits --rollback-on-failure on Helm 4 and is rejected with a clear Helm-4-required error on Helm 3. Flag assertions grep the `exec: helm upgrade --install` lines logged under --debug, matching flags as standalone tokens so the release name "issue-2712-atomic" cannot be confused with the "--atomic" flag. Verified locally against Helm 4.2.3: both atomic:true and rollbackOnFailure:true emit --rollback-on-failure with no --atomic.

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:
