I am trying to copy all the files from an image to a volume. However, kubernetes seems to not interpret the wildcard correctly. So, when I use the following, it fails with “not found”:

initContainers:
- name: init-container-name
  image: <image path>
  command:
  - cp
  - /foo/bar/*
  - /output

How can I get Kubernetes to interpret the * correctly? Is there a way to copy the contents without the surrounding bar folder?

I can copy the whole folder:

initContainers:
- name: init-container-name
  image: <image path>
  command:
  - cp
  - -r
  - /foo/bar
  - /output

But this results in an /output/bar when I just want the files themselves in output. I’ve also tried - "/foo/bar/*" and - "/foo/bar/"* but that doesn’t work either.
