Check if the cert-manager API is ready:

cmctl check api

Check the status of a certificate:

cmctl status certificate {{cert_name}}

Create a new certificate request based on an existing certificate:

cmctl create certificaterequest my-cr --from-certificate-file {{cert.yaml}}

Create a new certificate request, fetch the signed certificate, and set a maximum wait time:

cmctl create certificaterequest my-cr --from-certificate-file {{cert.yaml}} --fetch-certificate --timeout {{20m}}
