* feat: add per-release continue-on-error support

Work in progress for discussion #2799.

This introduces the initial release-level configuration needed to
continue processing independent releases after a deployment failure.
The DAG execution and failure propagation behavior are still being
implemented.

* fix: address review findings for continueOnError

Review fixes for the per-release continueOnError feature:

1. Regenerate values-file ID hashes in pkg/state/temp_test.go — adding
   ContinueOnError to ReleaseSpec shifts generateValuesID hashes, which
   broke TestGenerateID (the test file notes these must be regenerated
   whenever ReleaseSpec changes).

2. Remove the dead skippedErrors variable in withBatches and instead log
   each skipped release with logger.Warnf at decision time, so users see
   why a release never ran instead of only learning from the final error
   list.

3. Aggregate all errors from a state file instead of returning only
   errs[0] in visitStatesWithContext/processStateFileParallel. With
   continueOnError, multiple releases can fail or be skipped in one run;
   reporting only the first error hid the skip errors (and other
   failures), contradicting the feature's contract. Single-error
   rendering is unchanged.

4. Gate tolerated errors on ReleaseErrorCodeFailure so that non-failure
   release errors (e.g. helm-diff's "changes detected" exit code 2 can
   never enable continuation or block dependents.

5. Report skipped-release messages with the dependency's plain release
   name instead of its kubeContext/namespace-qualified needs id
   (e.g. dependency database instead of default/default/database),
   matching the documented message format.

6. Restructure the withBatches helpers into guard-clause style
   (filterBlockedReleases, toleratesBatchErrors) and drop the test-only
   logger nil-guards in favor of a nop logger in tests.

7. Add end-to-end coverage through App.Sync with the exectest fake helm:
   independent releases continue after a tolerated failure, dependents
   are skipped with an explicit error, the exit code stays non-zero, and
   fail-fast remains the default without continueOnError. Also cover the
   non-failure error code case at the withBatches level.

8. Use new(true) instead of a boolPtr helper (CI-enforced check-modernize)
   and document the failure-handling interaction in docs/releases.md.

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 helmfile assuming 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 init once 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:
