chore: simplify docker build process.

[appleboy]

• git tag v1.9.2 will publish docker tags 1, 1.9 and 1.9.2
• git tag v1.9.2-alpha.1 will publish docker tag 1.9.2-alpha.1

See the folllowings:

pipeline:
  publish_latest:
    image: plugins/docker
    repo: octocat/hello-world
-   tags: latest
+   default_tags: true
    when:
-     event: push
+     event: [ push, tag ]

- publish_release:
-   image: plugins/docker
-   repo: octocat/hello-world
-   tags: $DRONE_TAG
-   when:
-     event: tag

But will it keep only master branch for latest?

@lafriks Yes. it always does that since nobody can't create any branch on Gitea repo expect owner. Every need to fork this project to self-account and create a new branch, then send the PR.

[appleboy]

@lafriks I created new PR to fix your problem. drone-plugins/drone-docker#160

[lafriks]

@appleboy but there is also release branches that could possibly make latest not to be from master branch

[appleboy]

@lafriks Yes. so I created new PR to fix the condition for multiple branches.

[lafriks]

Would leaving branch: [ master ] would build only master branch and tags? If so that would work for us I think

[appleboy]

@lafriks We don't need to leave branch: [ master ].

[appleboy]

The docker plugin only builds image when branch equal to default branch of the project and push the tag event.

🤔

[bkcsoft]

Seeing as the announcement was Oct '17 (17.10) should we have to update this image tag as well?

[appleboy]

Done. f16eac1

[bkcsoft]

[appleboy]

Done. f16eac1

The above review comment should've been a "request change" 🙄
