* fix: helmDefaults.postRendererArgs not passed to helm commands (#2508)
The commit b5eb8793 (#1839) added template support for postRendererArgs
by copying HelmDefaults.PostRendererArgs to each release and then
niling out HelmDefaults.PostRendererArgs. However, the nil-out
prevented the fallback in appendPostRenderArgsFlags from ever being
reached, causing helmDefaults.postRendererArgs to be silently ignored
when no release-level postRendererArgs was set.
Remove the nil-out line so that HelmDefaults.PostRendererArgs remains
available as a fallback while still supporting template expressions
via the copy-to-release mechanism.

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:
