# This Dockerfile is not intended for general use, but is rather used to
|
|
# package up official Terraform releases (from releases.hashicorp.com) to
|
|
# release on Dockerhub as the "light" release images.
|
|
#
|
|
# The main Dockerfile in the root of the repository is more generally-useful,
|
|
# since it is able to build a docker image of the current state of the work
|
|
# tree, without any dependency on there being an existing release on
|
|
# releases.hashicorp.com.

|
|
# - Download the indicated release along with its checksums and signature for the checksums
|
|
# - Verify that the checksums file is signed by the Hashicorp releases key
|
|
# - Verify that the zip file matches the expected checksum
|
|
# - Extract the zip file so it can be run
