You can do that by running the following command\n\nBounded code example (external data; do not execute automatically):\n```shell\ncat <<EOF | kubectl apply -f -\napiVersion: certificates.k8s.io/v1\nkind: CertificateSigningRequest\nmetadata:\n  name: my-svc.my-namespace\nspec:\n  request: $(cat server.csr | base64 | tr -d '\\n')\n  signerName: example.com/serving\n  usages:\n  - digital signature\n  - key encipherment\n  - server auth\nEOF\n```\n\nNotice that the server.csr file created in step 1 is base64 encoded and stashed in the .spec.request field. You are also requesting a certificate with the \"digital signature\", \"key encipherment\", and \"server auth\" key usages, signed by an example example.com/serving signer. A specific signerName must be requested. View documentation for supported signer names for more information.\n\nThe CSR should now be visible in the API in a Pending state. You can see it by running\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl describe csr my-svc.my-namespace\n```\n\nBounded code example (external data; do not execute automatically):\n```none\nName:                   my-svc.my-namespace\nLabels:                 <none>\nAnnotations:            <none>\nCreationTimestamp:      Tue, 01 Feb 2022 11:49:15 -0500\nRequesting User:        yourname@example.com\nSigner:                 example.com/serving\nStatus:                 Pending\nSubject:\n        Common Name:    my-pod.my-namespace.pod.cluster.local\n        Serial Number:\nSubject Alternative Names:\n        DNS Names:      my-pod.my-namespace.pod.cluster.local\n                        my-svc.my-namespace.svc.cluster.local\n        IP Addresses:   192.0.2.24\n                        10.0.34.2\nEvents: <none>\n```\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
