SYNOPSIS

11       oc extract [OPTIONS]
12

DESCRIPTION

16       Extract files out of secrets and config maps
17
18
19       The  extract command makes it easy to download the contents of a config
20       map or secret into a directory. Each key in the config map or secret is
21       created  as a separate file with the name of the key, as it is when you
22       mount a secret or config map into a container.
23
24
25       You may extract the contents of a secret or config map to standard  out
26       by passing '-' to --to. The names of each key will be written to stdan‐
27       dard error.
28
29
30       You can limit which keys are extracted with the  --keys=NAME  flag,  or
31       set the directory to extract to with --to=DIRECTORY.
