Usage

This image should be a drop-in replacement for the upstream opa/gatekeeper image. See the full documentation for installation and usage.

See for the examples.

We can use the Chainguard image that we’ve built for Gatekeeper with the Helm chart of the project using the following commands.

First, you need to install the Helm repository:

helm repo add gatekeeper https://open-policy-agent.github.io/gatekeeper/charts

Once you did this, you can install Gatekeeper to the target cluster:

   helm install --name-template=gatekeeper \
		--namespace gatekeeper-system \
		--create-namespace \
	    --set image.repository="cgr.dev/chainguard/gatekeeper" \
	    --set image.release="latest" \
        gatekeeper/gatekeeper
