[FEATURE REQUEST] support image list layers, find file, view file contents, integration with DIVE

[Slach]

Is your feature request related to a problem? Please describe.
Sometimes I need to view actual file content of pulled images, currently, I try to use https://github.com/wagoodman/dive for it, but it cant show me contents of files which exist in layers wagoodman/dive#224

Describe the solution you'd like
I would like plugin integration between dive and k9s but the definition of done is ability to view file content inside image

Does not solve your problem but you could use the plugin function of k9s for dive:

plugin:
  dive:
    shortCut: d
    description: "Dive image"
    scopes:
      - containers
    command: dive
    background: false
    args:
      - $COL1

@derailed there seems to be a little bug with this when you have multiple containers in one pod, the $COL1 does not always select the correct row (tested with k9s 0.17.5)

@mycrEEpy I tried your suggestion, but it didn't work for me (k9s version 0.19.2). I think this feature would be awesome!! Thanks @derailed for this utility btw, I love k9s! 😍

@mycrEEpy this is the error I see:

10:36AM ERR Plugin Args match failed error="no environment matching key \"$COL1\":\"COL1\""

[mycrEEpy]

@yashbhutwala With k9s v0.17.7 the column reference for plugins changed from index to named columns. Above v0.17.7 it should work with:

plugin:
  dive:
    shortCut: d
    description: "Dive image"
    scopes:
      - containers
    command: dive
    background: false
    args:
      - $COL-IMAGE
