image history issues

[apostasie]

Description

This ticket is meant to list all current issues with nerdctl image history when compared with docker image history.

• 1. fails if multiple tags point to the same image
  • These are fundamentally the same image, with different tags.
  • Resolution here ties partly into the overall issue of image IDs (see nerdctl images displays the wrong image id #3011), and partly into the way we lookup images (which is currently being reworked in Image inspect rework #3017).
• 2. outputs spurious "Snapshot" property
  • We can just remove this - or leave it if it serves a purpose.
• 3. does not has "CreatedAt"
  • Easy to do, as we already have the info (used for CreatedSince)
• 4. size formatting leaves to be desired:

  • spurious space between number and unit "XXX B"

  • does not strip irrelevant digits (eg: 0.0 B)

  • Responsible package is in containerd (progress/humaans.go), which actually uses docker/go-units under the hood.

  • We are using it a few other places.

  • We could just drop the intermediary dependency and use go-units directly for better display.

• 5. does not list ID
  • This one also ties into nerdctl images displays the wrong image id #3011 and Image inspect rework #3017, and might be more involved to get done.
• 6. fails when using "format" and "quiet" together
• 7. does not implement the "human" flag - and overall doesn't display local time
• 8. "Snapshot" takes a lot of space with the table display, and should be truncated unless --no-trunc or --quiet

Steps to reproduce the issue

For 1:

nerdctl pull debian
nerdctl tag debian testtag
nerdctl image history fac2c0fd33e8

> FATA[0000] 1 errors:
multiple IDs found with provided prefix: fac2c0fd33e8

For 2:

nerdctl image history debian | jq .Snapshot

For 3:

nerdctl image history debian | jq .CreatedAt

For 4:

nerdctl image history debian | jq .Size

For 5:

nerdctl image history debian | jq .ID

For 6:

nerdctl image history --format json --quiet debian

Describe the results you received and expected

Expect to behave like docker.

I will send a PR that fixes the easy / non-controversial ones.
Let me know what you think about the other ones.

Thanks.
