Minimum Kubernetes Version

The minimum supported Kubernetes version for Gatekeeper is aligned with the Kubernetes releases listed in the Kubernetes Supported Versions policy. For more information, please see supported Kubernetes versions.

Note: Gatekeeper requires resources introduced in Kubernetes v1.16.

RBAC Permissions

For either installation method, make sure you have cluster admin permissions:

  kubectl create clusterrolebinding cluster-admin-binding \
--clusterrole cluster-admin \


Deploying a Release using Prebuilt Image

If you want to deploy a released version of Gatekeeper in your cluster with a prebuilt image, then you can run the following command:

kubectl apply -f

Deploying a Release using development image

If you want to deploy latest development version of Gatekeeper, you can use openpolicyagent/gatekeeper:dev tag or openpolicyagent/gatekeeper:<SHA>.

Images are hosted in OPA Docker Hub repository.

Deploying HEAD Using make

Currently the most reliable way of installing Gatekeeper is to build and install from HEAD:

  • Make sure that:
    • You have Docker version 19.03 or later installed.
    • Kubebuilder and Kustomize are installed.
    • Your kubectl context is set to the desired installation cluster.
    • You have a container registry you can write to that is readable by the target cluster.
  • Clone the Gatekeeper repository to your local system:
    git clone
  • cd to the repository directory.
  • Define your destination Docker image location:
  • Build and push your Docker image:
  • Finally, deploy:

Deploying via Helm

A basic Helm chart exists in charts/gatekeeper. If you have Helm installed, you can deploy via the following instructions for Helm v3:

helm repo add gatekeeper
helm install gatekeeper/gatekeeper --name-template=gatekeeper --namespace gatekeeper-system --create-namespace

If you are using the older Gatekeeper Helm repo location and Helm v3.3.2+, then use force-update to override the default behavior to update the existing repo.

helm repo add gatekeeper --force-update

Please note that this chart is compatible with Helm v3 starting with Gatekeeper v3.1.1. When using Helm v3, it is expected to see warnings regarding to crd-install hook. This is due to maintaining backwards compatibility with Helm v2 and should not impact the chart deployment.

You can alter the variables in charts/gatekeeper/values.yaml to customize your deployment. To regenerate the base template, run make manifests.


Using Prebuilt Image

If you used a prebuilt image to deploy Gatekeeper, then you can delete all the Gatekeeper components with the following command:

kubectl delete -f

Using make

If you used make to deploy, then run the following to uninstall Gatekeeper:

  • cd to the repository directory
  • run make uninstall

Using Helm

If you used helm to deploy, then run the following to uninstall Gatekeeper:

helm delete gatekeeper --namespace gatekeeper-system

Helm v3 will not cleanup Gatekeeper installed CRDs. Run the following to uninstall Gatekeeper CRDs:

kubectl delete crd -l

This operation will also delete any user installed config changes, and constraint templates and constraints.
