Release docker image

[eddycharly]

This is a try to configure goreleaser to publish docker images.

I don't know much about goreleaser so there are chances that it's not perfect.

Feel completely free to close the PR if it is not something you want to support, no worries.

Would also welcome this one, I actually just wanted to fork and contribute, then I saw this :) However, I would also create a GitHub actions pipeline for it. e.g.

.github/workflows/release.yaml

name: Release

on:
  push:
    tags:
    - "*"

jobs:
  goreleaser:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v1
    - uses: actions/setup-go@v2-beta
      with:
        go-version: '^1.14.1'
    - uses: actions/cache@v1
      with:
        path: /home/runner/go/pkg/mod
        key: go-mod-release
    - name: Login to Docker hub
      run: docker login -u ${{ secrets.DOCKER_HUB_USER }} -p ${{ secrets.DOCKER_HUB_PASSWORD }}
    - uses: goreleaser/goreleaser-action@v1
      with:
        args: release
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

@norwoodj would then only need to setup the Docker Hub user credentials in the repo secrets by creating a Token on Docker Hub in the account profile, so that no personal password is required.

@eddycharly thanks for the contribution! I'll merge and release this shortly. @ccremer I think this is a good idea, but I don't know anything about actions, so I'll probably leave that for a later issue. Please feel free to open an issue about adding an action like you've described.
