+# This Dockerfile builds on golang:alpine by building Terraform from source

+# This produces a docker image that contains a working Terraform binary along
+# with all of its source code, which is what gets released on hub.docker.com
+# as terraform:full. The main releases (terraform:latest, terraform:light and
+# the release tags) are lighter images including only the officially-released
+# binary from releases.hashicorp.com; these are built instead from
+# scripts/docker-release/Dockerfile-release.
