This repository contains Cert Manager Operator designed for OpenShift. The operator runs in openshift-cert-manager-operator
namespace, whereas its operand in cert-manager
. Both those namespaces are hardcoded.
The Operator uses the upstream deployment manifests. It divides them into separate files and deploys using 3 controllers:
- cert_manager_cainjector_deployment.go
- cert_manager_controller_deployment.go
- cert_manager_webhook_deployment.go
The Operator automatically deploys a cluster-scoped CertManager
object named cluster
if it's missing (with default values).

Connect to your OpenShift cluster and run the following command:
make local-run
This command will install all the necessary Operator manifests as well as all necessary CRDs. After this part is complete, it will run the Operator locally.
Connect to your OpenShift cluster and run the following command:
make operator-clean operator-push-bundle operator-run-bundle IMAGE_REGISTRY=<registry>/<org>
This command will:
- remove any existing operator that might be in your cluster
- build and push the bundle into
<registry>/<org>/cert-manager-operator-bundle:latest
- download Operator SDK if necessary
- install the bundle into your cluster
!!! WARNING !!!
As for the time-being, the bundle uses a hardcoded image in slaskawi
's repo. This will change when we start building
the Operator images on each commit.

Check the changes in the bindata/

The testsuite assumes, that Cert Manager Operator has been successfully deployed in the cluster and
it also successfully deployed Cert Manager (the operand). This is exactly what Prow is doing in cooperation with
make test-e2e-wait-for-stable-state
.
If you'd like to run all the tests locally, you need to ensure the same requirements are met. The easiest way to do it is to:
make local-deploy-manifests local-run
Then, let it run for a few minutes. Once the operands are deployed, just invoke:
make test-e2e -o test-e2e-wait-for-stable-state
The -o test-e2e-wait-for-stable-state
skips checking if the operator is deployed. Depending on how do you're testing it,
you may or may not want to invoke it.
It is possible (although not supported) to specify custom settings to each Cert Manager image. In order to do it,
you need to modify the certmanager.operator/cluster
object:
apiVersion: operator.openshift.io/v1alpha1
kind: CertManager
metadata:
name: cluster
spec:
managementState: "Managed"
unsupportedConfigOverrides:
# Here's an example to supply custom DNS settings.
controller:
args:
- --v=2
- --cluster-resource-namespace=$(POD_NAMESPACE)
- --leader-election-namespace=kube-system
- --dns01-recursive-nameservers-only
- --dns01-recursive-nameservers=8.8.8.8:53,8.8.4.4:53
