version: Use linker flag Embedding the version file is slightly annoying for packaging, because the release tarball is not a git repository and so "go generate" would fail. Instead a packager would have to manually create the version.txt file. With using a linker flag, the version string has a graceful fallback. 2023-02-16 13:06:21 +01:00			`RUN go build -ldflags="-X main.version=$(git describe --long)" -o /app/ntfy-alertmanager`
