Chris Halcrow asked:
I was passed the following, which does a dry run of the creation of a kubernetes secret from an
appsettings.json file, which is then piped to a kubernetes
apply. I think that the
-f will take the filename of the
--dry-run created secret and use that when applying the secret, but I’m wondering if the trailing
- has any significance or if it’s just a typo?
kubectl create secret generic test --from-file=appsettings.json --dry-run -oyaml | kubectl apply -f -
- is a parameter to the
-f option, which means to accept input from standard input instead of a named file. Hundreds of UNIX/Linux commands have options like this.
