🎀 OC ADM OCP-CERTIFICATES(1) 🎀

okay bestie, this page comes from the Openshift CLI User Manuals, dated June 2016, and it's giving very specific cert-regeneration energy. let's go. 💅

🌸 NAME 🌸

oc adm ocp-certificates regenerate-machine-config-server-serving-cert — regenerate the machine config operator certificates in an OpenShift cluster.

✨ SYNOPSIS ✨

oc adm ocp-certificates regenerate-machine-config-server-serving-cert [OPTIONS]

🦋 DESCRIPTION 🦋

Regenerate the Machine Config Operator certificates for an OCP v4 cluster. This is the certificate used to verify the MCS contents when a new node attempts to join the cluster.

Experimental, bestie: this command is under active development and may change without notice. 👀

💖 OPTIONS 💖

• --update-ignition=true — if true, automatically update user-data secrets (ignition) in the machine-api namespace. Not useful if node scaling is not backed by a MachineSet.

👑 OPTIONS INHERITED FROM PARENT COMMANDS 👑

These cuties come from the parent command, so don't forget they're in the group chat too:

• --as="" — username to impersonate for the operation. User could be a regular user or a service account in a namespace.
• --as-group=[] — group to impersonate for the operation; this flag can be repeated to specify multiple groups.
• --as-uid="" — UID to impersonate for the operation.
• --as-user-extra=[] — user extras to impersonate for the operation; this flag can be repeated to specify multiple values for the same key.
• --cache-dir="/homeless-shelter/.kube/cache" — default cache directory.
• --certificate-authority="" — path to a cert file for the certificate authority.
• --client-certificate="" — path to a client certificate file for TLS.
• --client-key="" — path to a client key file for TLS.
• --cluster="" — the name of the kubeconfig cluster to use.
• --context="" — the name of the kubeconfig context to use.
• --disable-compression=false — if true, opt-out of response compression for all requests to the server.
• --insecure-skip-tls-verify=false — if true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure.
• --kubeconfig="" — path to the kubeconfig file to use for CLI requests.
• --kuberc="" — path to the kuberc file to use for preferences. This can be disabled by exporting KUBECTL_KUBERC=false feature gate or turning off the feature KUBERC=off.
• --match-server-version=false — require server version to match client version.
• -n, --namespace="" — if present, the namespace scope for this CLI request.
• --profile="none" — name of profile to capture. One of (none|cpu|heap|goroutine|threadcreate|block|mutex).
• --profile-output="profile.pprof" — name of the file to write the profile to.
• --request-timeout="0" — the length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests.
• -s, --server="" — the address and port of the Kubernetes API server.
• --tls-server-name="" — server name to use for server certificate validation. If it is not provided, the hostname used to contact the server is used.
• --token="" — bearer token for authentication to the API server.
• --user="" — the name of the kubeconfig user to use.
• --warnings-as-errors=false — treat warnings received from the server as errors and exit with a non-zero exit code.

🍓 EXAMPLE 🍓

# Regenerate the MCO certs without modifying user-data secrets
oc adm ocp-certificates regenerate-machine-config-server-serving-cert --update-ignition=false

# Update the user-data secrets to use new MCS certs
oc adm ocp-certificates update-ignition-ca-bundle-for-machine-config-server
