nelm — multi-arch Docker image

Docker image packaging werf/nelm, a Helm alternative for deploying Helm Charts to Kubernetes. The image also bundles the latest stable kubectl.

Published to:

• Docker Hub: hsww/nelm
• GHCR: ghcr.io/hsw/nelm

Platforms: linux/amd64, linux/arm64. Binaries are verified against the upstream GPG signature during build.

About nelm

Nelm is a Kubernetes deployment tool built on a partially rewritten Helm codebase. Compared to Helm it adds, among other things:

• terraform plan-style release planning
• improved CRD management
• out-of-the-box secrets management
• advanced resource ordering and lifecycle
• continuous streaming of logs, events, and resource status during deploy
• hundreds of Helm bug fixes

It is backward-compatible with Helm Charts and Helm Releases — no migration needed.

See the upstream README for the full feature list, CLI reference, and documentation.

Usage

# Show version
docker run --rm hsww/nelm:stable nelm version

# Render a chart from the current directory
docker run --rm -v "$PWD:/chart" -w /chart hsww/nelm:stable \
  nelm chart render

# Deploy using your host kubeconfig
docker run --rm \
  -v "$HOME/.kube:/root/.kube:ro" \
  -v "$PWD:/chart" -w /chart \
  hsww/nelm:stable \
  nelm release install -n myproject -r myproject

Default command is nelm. Both nelm and kubectl are on PATH, so any command can be overridden (e.g. docker run --rm hsww/nelm:stable kubectl version --client).

Tag policy

• Semver tags (x.y.z, x.y, x) follow nelm releases.
• Quality labels (ea, stable, rock-solid, latest) move to newer versions automatically, matching upstream promotions.

The tag-to-version mapping shown at the top of this page is refreshed daily by CI.
