Show tree only for a specific image

[omerlh]

First, thanks - this is a really nice tool :)
Instead of showing the tree for all the images, I want to show the tree only for a specific image - is that something that is supported?

[omerlh]

Found it: dockviz images microsoft/dotnet:2.1-aspnetcore-runtime -t.

[omerlh]

Sorry for the mess, this is not what I wanted - this show all images based on this image, I want the opposite behavior - all the children of this image.

[justone]

No worries.

Can you show me some example output so I can see what you mean?

[omerlh]

This is the output of docker inspect:

OmerL-Mac:api omerl$ docker inspect local/api:1 -f "{{.RootFS.Layers}}"
[sha256:cdb3f9544e4c61d45da1ea44f7d92386639a052c620d1550376f22f5b46981af sha256:3cf68b57ae879122a4c012a92d4948e7a3e64c48a0d09ee0cfbcbf5742367837 sha256:324d9a4273a97e634a3bda9490cd77689c5549f5bd512f40c853b047f7e814d6 sha256:9f652cc2dda0dedd64b65868fca54329b4794f60cb808669d26b079d6d94619c sha256:0636369cabe0f083672fad3295d3c0092c1252c53cb1a72f59c46881444b6216 sha256:588e6933c934fc4b9c34a2543bd86a0162d53eff10adf4aa5efe42ab233ac436 sha256:36ceea3b65f51467a8723dc6ec0abeaa809e89ca1e8d0b7a484d064cc6eaf17e]

I want to visualize this tree - starting from my local image up to the first image.
Also - Is there a way to fetch image names even if it's not on my machine?

So, given this tree of images:

└─735f80812f90 Virtual Size: 83.5 MB Tags: ubuntu:latest
  └─290405e733b3 Virtual Size: 218.1 MB
    └─888dd32677de Virtual Size: 218.1 MB Tags: test:first
      └─69029a86ab24 Virtual Size: 220.6 MB
        └─6afb04494dd1 Virtual Size: 220.6 MB Tags: test:second

When you run dockviz images -t test:first, you get this:

└─888dd32677de Virtual Size: 218.1 MB Tags: test:first
  └─69029a86ab24 Virtual Size: 220.6 MB
    └─6afb04494dd1 Virtual Size: 220.6 MB Tags: test:second

What I think you're asking for is something that will show this:

└─735f80812f90 Virtual Size: 83.5 MB Tags: ubuntu:latest
  └─290405e733b3 Virtual Size: 218.1 MB
    └─888dd32677de Virtual Size: 218.1 MB Tags: test:first

Is that correct?

[omerlh]

yep that correct.

[justone]

Ah. So you'd like to see the ancestry for a particular image. Could you use docker history [imageid] instead?

And to answer your other question (Is there a way to fetch image names even if it's not on my machine?). No, you can't fetch the other names. This is a limitation that Docker imposes.

[omerlh]

Thanks. Currently I do using docker-history, just thought visualization could be nice :)

Yep.. having visualization of a specific image and the ancestry would be awsome.
