Point in time releases

The following Docker image tags are built once and can be used for reproducible builds. Its version never changes so you will have to update tags in your pipelines from time to time in order to stay up-to-date.

πŸ“‚ Docker mounts

The working directory inside the Docker container is /data/ and should be mounted to your local filesystem where your Terragrant project resides. (See Examples for mount location usage.)

πŸ’» Usage

docker run --rm -v $(pwd):/data cytopia/terragrunt terragrunt <ARGS>
docker run --rm -v $(pwd):/data cytopia/terragrunt terraform <ARGS>

πŸ”  Environment variables

The following environment variables will ease your life when mounting directories into the docker container by maintaining file system permissions.

Variables Default Description
RUN_NON_ROOT 0 Set to 1 to run commands as user instead of root.
UID 1000 Set to the uid of your local user (id -u) if you want to run as non root.
GID 1000 Set to the gid of your local user (id -g) if you want to run as non root.

ℹ️ Examples

1. Simple: Provision single sub-project on AWS

1.1 Project overview

Let's assume your Terragrunt project setup is as follows:

/my/tf                                              # Terragrunt project root
β”œβ”€β”€ backend-app
β”‚   β”œβ”€β”€ main.tf
β”‚   └── terragrunt.hcl
β”œβ”€β”€ frontend-app
β”‚   β”œβ”€β”€ main.tf
β”‚   └── terragrunt.hcl
β”œβ”€β”€ mysql                                           # MySQL sub-project directory
β”‚   β”œβ”€β”€ main.tf
β”‚   └── terragrunt.hcl
β”œβ”€β”€ redis
β”‚   β”œβ”€β”€ main.tf
β”‚   └── terragrunt.hcl
└── vpc
    β”œβ”€β”€ main.tf
    └── terragrunt.hcl

The MySQL sub-project you want to provision is at the releative path mysql/.

1.2 To consider

  1. Mount the terragrunt root project dir (/my/tf/) into /data/ into the container
  2. Use the workding dir (-w or --workdir) to point to your project inside the container
  3. Add AWS credentials from your environment to the container

1.3 Docker commands

# Initialize the MySQL project
docker run --rm \
  -e AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID \
  -e AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY \
  -e AWS_SESSION_TOKEN=$AWS_SESSION_TOKEN \
  -u $(id -u):$(id -g) \
  -v /my/tf:/data \
  -w /data/mysql \
  cytopia/terragrunt terragrunt init

# Plan the MySQL project
docker run --rm \
  -e AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID \
  -e AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY \
  -e AWS_SESSION_TOKEN=$AWS_SESSION_TOKEN \
  -u $(id -u):$(id -g) \
  -v /my/tf:/data \
  -w /data/mysql \
  cytopia/terragrunt terragrunt plan

# Apply the MySQL project
docker run --rm \
  -e AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID \
  -e AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY \
  -e AWS_SESSION_TOKEN=$AWS_SESSION_TOKEN \
  -u $(id -u):$(id -g) \
  -v /my/tf:/data \
  -w /data/mysql \
  cytopia/terragrunt terragrunt --terragrunt-non-interactive apply

2. Complex: Provision single sub-project on AWS

2.1 Project overview

Let's assume your Terragrunt project setup is as follows:

The VPC sub-project you want to provision is at the relative path envs/aws/dev/eu-centra-1/infra/vpc-k8s/.

2.2 To consider

  1. Mount the terragrunt root project dir (/my/tf/) into /data/ into the container
  2. Use the workding dir (-w or --workdir) to point to your project inside the container
  3. Add AWS credentials from your environment to the container

2.3 Docker commands

# Initialize the VPC project
