Prepare

if you use assume role, you can do,

$ head -1 local.env.sample > local.env
$ vi local.env
$ ( cd .. && git clone https://github.com/clairvy/assume_role.git )   # you can modify your .aws setting
$ ( cd ../assume_role && docker-compose run --rm app ruby -I lib bin/assume_role ) >> local.env

Run

$ mkdir tf
$ docker-compose run --rm app sh -x /mnt/terraforming.sh /mnt/tf
$ docker-compose run --rm tf plan

docker-compose.yml

app:
    image: quay.io/dtan4/terraforming:latest
    volumes:
        - .:/mnt
    env_file:
        - ./local.env
tf:
    image: uzyexe/terraform
    volumes:
