Docker - common command to install Terraform, AWS-Vault, Terragrunt and grant gitlab access

Docker image to install Terraform, AWS-Vault, Terragrunt and grant gitlab access

When build image, you can run:

docker build -t docker_name:tag . --force-rm --build-arg SSH_PRIVATE_KEY=""

To use local AWS environment, you can run docker image like:

docker run -ti --env-file <(aws-vault exec your_role -- env | grep -e ^AWS_) docker_name:tag 

In that case, you don't need to put aws-vault when you run .sh command. instead, you can just execute
