Is your feature request related to a problem? Please describe.
spinach configuration allows you to skip all checks for a container or codes for all containers in a pod. I'd like to skip particular codes on specific containers.

e.g. I know my 'fred' pod has a 'jim' container that has to run as root, but would like to check other problems on that container and other containers in the same pod running as root

Describe the solution you'd like
Allow specification of a list of codes on a container. Something like

popeye:
  excludes:
    v1/pods:
    - name: rx:fred
      containers:
        - name: jim
          codes:
              302

Describe alternatives you've considered
Could alternatively have a different field e.g. 'containercodes' which is a map of container names to lists of codes, rather than redefining 'containers' to be structured
At present I need to leave codes unsuppressed and postprocess the Popeye output.
