How to Enable Auto Approval of CSR in Openshift v3.11

Page content

Nodes certificates are not Completely redeployed through playbook but through a different mechanism.

Parts of the Openshift series

SSL Certificates will be valid for the period of 1 year and at 85% of the certificate the node will trigger a CSR that would have to be approved for the certificate to be redeployed.

The Only certificates that are renewed/redeployed through CSR’s mechanism are the kubelet/nodes certificates. Any other certificates e.g, router, master, api certs, etcd, docker-registry, etc are still redeployed through the usual playbooks.

If triggered CSR is not approved either manually or in automated way then after one year all nodes will go to NotReady State.

Check and approve csr’s manually

oc get csr
oc describe csr <csr_name>
oc adm certificate <approve csr_name>

oc get csr -o name | xargs oc adm certificate approve

Approve csr’s automaticle

ansible-playbook /usr/share/ansible/openshift-ansible/playbooks/openshift-master/enable_bootstrap.yml \
-e openshift_master_bootstrap_auto_approve=true
