Different Docker image tags for release and snapshot

[mih-kopylov]

The goal is to make goreleaser release --snapshot to build and push a docker image with {{ .Tag }}-SNAPSHOT tag only, while goreleaser release will push an image with all tags, including latest.

I've prepared two docker profiles for that, but struggling how to pass an id to goreleaser release command.

dockers:
  - id: release
    image_templates:
      - "repo/name:{{ .Tag }}"
      - "repo/name:{{ .Major }}"
      - "repo/name:{{ .Major }}.{{ .Minor }}"
      - "repo/name:latest"
  - id: snapshot
    image_templates:
      - "repo/name:{{ .Tag }}-SNAPSHOT"

How to do that?

you can't pass ids to the release command.

you can use {{.IsSnapshot}} in the templates though.

PS: empty image names are ignored, so if you could do something like:

dockers:
  - 
    image_templates:
      - "{{ if not .IsSnapshot }}repo/name:{{ .Tag }}{{ end }}"
      - "{{ if not .IsSnapshot }}repo/name:{{ .Major }}{{ end }}"
      - "{{ if not .IsSnapshot }}repo/name:{{ .Major }}.{{ .Minor }}{{ end }}"
      - "{{ if not .IsSnapshot }}repo/name:latest{{ end }}"
      - "{{ if .IsSnapshot }}repo/name:{{ .Tag }}-SNAPSHOT{{ end }}"

finally, if you want to push snapshots, you'll need to do it manually, or use the nightly feature from goreleaser-pro.
