Self-Host Guide with Docker

• Build locally:

docker build -t delphitools:latest .
# Optional: stamp the in-app version label (shown when hovering the logo).
# .git is not in the build context, so pass the SHA explicitly:
docker build --build-arg COMMIT_SHA=$(git rev-parse --short HEAD) -t delphitools:latest .

• Run locally:

# serve on http://localhost:3000 
docker run --rm -p 3000:80 delphitools:latest

• With docker-compose:

## to start the container
docker-compose up -d --build
## stamp the version label too (otherwise it shows "dev"):
COMMIT_SHA=$(git rev-parse --short HEAD) docker-compose up -d --build
## to stop the container
docker-compose down
