feat: docker buildx context error

[tcurdt]

Provide more context for the error message and point to the documentation.

It gives the users more context on the error and instructions to fix the problem.

Fixes the issue discussed in #4392

Sorry for the commit message formats. Read that too late.
I hope you can fix that using a "squash and merge"?

[tcurdt]

It's a little weird. The message isn't quite what it should be though:

  ⨯ release failed after 1s                  error=docker build failed: failed to build tcurdt/foo:latest: exit status 1: ERROR: use `docker --context=default buildx` to switch to context "default"

while the error is

docker buildx not set to default context
Please switch with 'docker context use default'

Any idea why it's such a mixture?

probably some other function is wrapping it, lemme clone your branch and take a look

[caarlos0]

the proposed changes fixed it to me:

  • docker images
    • building docker image                          image=goreleaser/goreleaser:v1.21.3-next-arm64
    • building docker image                          image=goreleaser/goreleaser:v1.21.3-next-amd64
    • took: 2s
  ⨯ release failed after 12s                 error=docker build failed: docker buildx not set to default context, please switch using 'docker context use default'

no problem! I usually squash merge PRs, so its all good :)

[caarlos0]

also sorry for the delay, dunno what happened, I was debugging this, something happened, and I forgot it for 24hrs for some reason

No worries. Still much quicker than expected :)
Thanks for the review!

The changes made sense.
Hope it's ready for merge then.
