Dockerize the application

[jonaustin09]

Describe the solution you'd like Implement a docker-compose.yml file to run the build "app" service and run the application as a docker container. Set a volume host to the project root to map all the changes from the project to the docker container. Make sure the server is restarted inside the docker container on every file change.

I've worked with goreleaser a few times to publish docker containers as part of the release process. I didn't originally find it straightforward, but ultimately was satisfied with the results. The goreleaser philosophy does the full build once, outside the container and then expects to copy the binaries from an earlier step into the container. This negates the need for multi-stage builds and encourages consistency at the binary level. It also sets up the context for the docker build within the dist/ directory as appropriate for the architecture.

If useful, I can add this content to a PR or add more details.

Changes requried include two files. The first adds a dockers stanza to the .goreleaser.yaml file and a the second is a dedicated Dockerfile for the release. Here's an example of both:

goreleaser.yaml

dockers:
  - image_templates:
      - ghcr.io/versity/{{.ProjectName}}:latest
      - ghcr.io/versity/{{.ProjectName}}:{{ .Tag }}
      - ghcr.io/versity/{{.ProjectName}}:{{ .Major }}
      - ghcr.io/versity/{{.ProjectName}}:{{ .Major }}.{{ .Minor }}
    build_flag_templates:
      - "--pull"
      - "--label=org.opencontainers.image.created={{.Date}}"
      - "--label=org.opencontainers.image.title={{.ProjectName}}"
      - "--label=org.opencontainers.image.revision={{.FullCommit}}"
      - "--label=org.opencontainers.image.version={{.Version}}"
    extra_files:
      - LICENSE
      - README.md
    dockerfile: Dockerfile.goreleaser
