* Use goreleaser to build and push docker images * Update CircleCI config to install goreleaser dependencies * Update goreleaser.sh to create a temporary tag when CIRCLE_TAG is not set * Update Dockerfile for goreleaser * Update goreleaser.sh to trap errors and cleanup temporary git branch, for local runs * Update goreleaser.sh to envsubst specific variables, to not break the `sign` section using signature and artifact variables * Fix goreleaser.sh logic to only release when CIRCLE_TAG is set
