So I'm not sure what's actually happening here, but ulimit isn't an executable, it's a built-in to your shell:

$ which ulimit || echo "couldn't find it"
couldn't find it

A number of things:

• Try changing your command to bash -c "ulimit -Sn".
• The environment variables might not be the same as in your shell session during the Goss execution.
• degoss could be executing as a user you don't expect.

We'd need to extend the degoss module to add env_vars to be able to set your environment the way you'd expect. I removed environment variables in a previous major release, might have to add them back in for this use case.

I'd try using a become_user on your degoss role if you want a very specific user to execute things:

- name: my play
  roles:
    - role: degoss
      # ...
      become: true
      become_user: doctorstevebrule
