Modify kubeconfig files

Eric Paris Jan 2015

Synopsis

kubectl config [OPTIONS]

Description

Modify kubeconfig files using subcommands like "kubectl config set current-context my-context"

The loading order follows these rules:

  1. If the --kubeconfig flag is set, then only that file is loaded. The flag may only be set once and no merging takes place.
  2. If $KUBECONFIG environment variable is set, then it is used as a list of paths (normal path delimiting rules for your system). These paths are merged. When a value is modified, it is modified in the file that defines the stanza. When a value is created, it is created in the first file that exists. If no files in the chain exist, then it creates the last file in the list.
  3. Otherwise, ${HOME}/.kube/config is used and no merging takes place.

--logtostderr=true log to standard error instead of files

--machine-id-file="/etc/machine-id,/var/lib/dbus/machine-id" Comma-separated list of files to check for machine-id. Use the first one that exists.

--match-server-version=false Require server version to match client version

-n, --namespace="" If present, the namespace scope for this CLI request

--profile-output="profile.pprof" Name of the file to write the profile to

--referenced-reset-interval=0 Reset interval for referenced bytes (container_referenced_bytes metric), number of measurement cycles after which referenced bytes are cleared, if set to 0 referenced bytes are never cleared (default: 0)

--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.
