Terraform Docker Release Build
This directory contains configuration to drive the Dockerhub automated build for Terraform. This is different than the root Dockerfile (which produces the "full" image on Dockerhub) because it uses the release archives from releases.hashicorp.com. It is therefore not possible to use this configuration to build an image for a commit that hasn't been released.
How it works
Dockerhub runs the hooks/build script to trigger the build. That uses
git describe to identify the tag corresponding to the current HEAD. If
the current commit isn't tagged with a version number corresponding to
a Terraform release already on releases.hashicorp.com, the build will fail.
What it produces
This configuration is used to produce the "latest", "light", and "beta" tags in Dockerhub, as well as specific version tags.
- "latest" and "light" are synonyms, and are built from a branch in this repository called "stable".
- "beta" is built from a branch called "beta".
All of these branches should be updated only to tagged commits, and only when it is desirable to create a new release image.
The full and master images image
This configuration does not produce the "full" image. That is instead produced
by the Dockerfile in the repository root, driven by updates to the "stable"
branch.
The "master" tag is updated for every commit to the master branch of the Terraform core repository. It is not recommended to use these images for any production use, but they can be useful for testing bleeding-edge features that are not yet included in a release.
