Get This Release

Install the OCM CLI

curl -sfL https://ocm.software/install-cli.sh | OCM_VERSION=0.19.0 bash

For alternative installation options, see the installation guide.

You can also run the OCM CLI in a container without installing it:

docker run --rm -t ghcr.io/open-component-model/cli:0.19.0 --help

See the container image guide for more details.

Deploy the OCM Controller

Install into a Kubernetes cluster via Helm:

helm install ocm-k8s-toolkit oci://ghcr.io/open-component-model/kubernetes/controller/chart \
--version 0.19.0 \
--namespace ocm-k8s-toolkit-system \
--create-namespace

See the controller setup guide for full configuration options.

OCM Component Distribution (for existing OCM users)

Every OCM release is published as OCM component versions to ghcr.io/open-component-model - the same distribution mechanism OCM enables for your own software. Components in this release:

Component Contents
ocm.software/ocm:0.19.0 Product wrapper referencing CLI + controller
ocm.software/cli:0.19.0 CLI binaries and OCI image
ocm.software/kubernetes/controller:0.19.0 Controller image and Helm chart

Inspect the full product component:

ocm get component-version ghcr.io/open-component-model//ocm.software/ocm:0.19.0 -o yaml

Download a CLI binary directly via OCM (requires OCM CLI already installed; replace os and architecture as needed — e.g. linux/amd64, darwin/arm64):

ocm download resource ghcr.io/open-component-model//ocm.software/cli:0.19.0 \
--identity os=linux,architecture=amd64
