9 kubectl config - Modify kubeconfig files
10
14 kubectl config [OPTIONS]
15
19 Modify kubeconfig files using subcommands like "kubectl config set cur‐
20 rent-context my-context"
21 The loading order follows these rules:
24 1. If the --kubeconfig flag is set, then only that file is
27 loaded. The flag may only be set once and no merging takes
28 place.
29 2. If $KUBECONFIG environment variable is set, then it is used
31 as a list of paths (normal path delimiting rules for your
32 system). These paths are merged. When a value is modified,
33 it is modified in the file that defines the stanza. When a
34 value is created, it is created in the first file that ex‐
35 ists. If no files in the chain exist, then it creates the
36 last file in the list.
37 3. Otherwise, ${HOME}/.kube/config is used and no merging
39 takes place.
