OC-ADM-OCP-CERTIFICATES-UPDATE-IGNITION-CA-BUNDLE-FOR-MACHINE-CONFIG-SERVER(1)

🌸 NAME 🌸

Bestie, welcome to the OC ADM OCP-CERTIFICATES(1) manual page — aka the home of oc adm ocp-certificates and its sub-command update-ignition-ca-bundle-for-machine-config-server. The short version? It updates user-data secrets in an OpenShift cluster so they use updated MCO certfs. Slay. 💅

---

✨ SYNOPSIS ✨

oc adm ocp-certificates update-ignition-ca-bundle-for-machine-config-server [OPTIONS]

---

🦋 DESCRIPTION 🦋

Okay so this command regenerates the Machine Config Operator certificates for an OCP v4 cluster. This is the certificate used to verify the MCS contents when a new nodes attempts to join the cluster. That's literally the whole plot, bestie. 🎀

Experimental, no cap: This command is under active development and may change without notice. So don't act brand new when it shifts. 😭

💖 OPTIONS INHERITED FROM PARENT COMMANDS 💖

These are the parent-command flags you inherit, fr fr. Every flag, default, and value below is exactly what you get:

• --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 🎀

Here's the vibe in actual commands, copied exactly:

# 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
