How to Release Binaries

See goreleaser's requirements here.

Get a GitHub Personal Access Token and add the repo scope. Set GITHUB_TOKEN to this value:

export GITHUB_TOKEN=...

See here for more information on github tokens.

Choose a tag/release name, create and push a tag:

TAG=v0.0.1

git tag $TAG
git push origin $TAG

You'll need to be logged in to dockerhub from the command line, in order to push images: docker login

Cut a release:

goreleaser release --clean

Make a test release:

goreleaser release --snapshot --clean
