kubeadm config --help
There is a ConfigMap in the kube-system namespace called "kubeadm-config" that kubeadm uses to store internal configuration about the
cluster. kubeadm CLI v1.8.0+ automatically creates this ConfigMap with the config used with 'kubeadm init', but if you
initialized your cluster using kubeadm v1.7.x or lower, you must use the 'config upload' command to create this
ConfigMap. This is required so that 'kubeadm upgrade' can configure your upgraded cluster correctly.
Usage:
kubeadm config [flags]
kubeadm config [command]
Available Commands:
images Interact with container images used by kubeadm
migrate Read an older version of the kubeadm configuration API types from a file, and output the similar config object for the newer version
print Print configuration
Flags:
-h, --help help for config
--kubeconfig string The kubeconfig file to use when talking to the cluster. If the flag is not set, a set of standard locations can be searched for an existing kubeconfig file. (default "/etc/kubernetes/admin.conf")
Global Flags:
--add-dir-header If true, adds the file directory to the header of the log messages
--log-file string If non-empty, use this log file (no effect when -logtostderr=true)
--log-file-max-size uint Defines the maximum size a log file can grow to (no effect when -logtostderr=true). Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
--one-output If true, only write logs to their native severity level (vs also writing to each lower severity level; no effect when -logtostderr=true)
--rootfs string [EXPERIMENTAL] The path to the 'real' host root filesystem.
--skip-headers If true, avoid header prefixes in the log messages
--skip-log-headers If true, avoid headers when opening log files (no effect when -logtostderr=true)
-v, --v Level number for the log level verbosity
