This Docker image is pulling the atlantis image from runatlantis/atlantis, and additionaly installs Terraform and Terragrunt for further use. The Dockerfile was adapted from https://github.com/chenrui333/atlantis-terragrunt

For building you can overwrite your desired versions with the following three Makefile variables:

• ATLANTIS
• TERRAFORM
• TERRAGRUNT

make build
make build TERRAFORM=0.12.31
make build TERRAFORM=0.12.31 TERRAGRUNT=0.25.5
make build TERRAFORM=0.12.31 TERRAGRUNT=0.25.5 ATLANTIS=0.16.1

Immutable images are created when this git repository is tagged. The Docker image tags are in the following format:

flaconi/atlantis-terragrunt:<ATLANTIS_VERSION>-<TERRAFORM_VERSION>-<TERRAGRUNT_VERSION>-<GIT_TAG>

Mutable images are created on release-* branches and master merge

# On release-* branch
flaconi/atlantis-terragrunt:<ATLANTIS_VERSION>-<TERRAFORM_VERSION>-<TERRAGRUNT_VERSION>-release-<SUFFIX>

# On master
flaconi/atlantis-terragrunt:<ATLANTIS_VERSION>-<TERRAFORM_VERSION>-<TERRAGRUNT_VERSION>

This Docker entrypoint will look for env var GITHUB_USER_KEY, in case it exists, it will do the following to set a private key on the atlantis docker task.

echo "${GITHUB_USER_SSH_KEY}" | base64 -d | gunzip > "${HOME}/.ssh/id_rsa"
