This topic explains how to specify a custom Kubernetes namespace for
cert-manager.
In most cases, cert-manager runs in the cert-manager namespace. Some users may have
company policies restricting the creation of new Kubernetes namespaces or have policies requiring
cert-manager to be run in a different namespace, for example kube-system.
Verify that cert-manager installed correctly in the new namespace with the
kubectl get pods command:
kubectl get pods -n new-cert-manager-namespace
NAME READY STATUS RESTARTS AGE
cert-manager-1234567-abcde 1/1 Running 0 21s
cert-manager-cainjector-23456789a-bcdef 1/1 Running 0 22s
cert-manager-webhook-3456789ab-cdef0 1/1 Running 0 20s
If cert manager had previoiusly been running, delete the cert-manager instance in
the cert-manager namespace by following the instructions in
Uninstall
in the cert-manager documentation.
