Docker

Image

Published to GitHub Container Registry on every GitHub Release:

ghcr.io/danielgtmn/domain-mcp

Tags

When you publish a release tagged v1.2.3, the workflow pushes:

Tag	Example
Full version	1.2.3
With v prefix	v1.2.3
Major.minor	1.2
Major	1 (stable releases only)
latest	floating tip (stable releases only; not on prereleases)

Prereleases (GitHub “This is a pre-release”) skip latest and the bare major tag.

Pull & run

docker pull ghcr.io/danielgtmn/domain-mcp:latest

# stdio MCP — keep -i so the client can talk to the process
docker run -i --rm ghcr.io/danielgtmn/domain-mcp:0.1.0

Build locally

docker build -t domain-mcp:local .
docker run -i --rm domain-mcp:local

Release pipeline

Workflow: .github/workflows/release-docker.yml

1. Maintainer publishes a GitHub Release with tag vX.Y.Z.
2. Action checks out that tag.
3. Multi-arch build (linux/amd64, linux/arm64).
4. Push to ghcr.io/<owner>/domain-mcp with version-derived tags.

Manual re-run: Actions → Release Docker Image → Run workflow (optional tag input).

First-time GHCR visibility

New packages may default to private. In GitHub:

Package settings → Change visibility → Public

so others can docker pull without auth.
