Getting started

1. Write terraform-bundle.hcl

#
# Configuration used by terraform-bundle to fetch all required plugins ONCE.
#
# (see https://github.com/hashicorp/terraform/tree/master/tools/terraform-bundle)
# (why https://github.com/hashicorp/terraform/issues/15801)
#

terraform {
  version = "0.11.10"
}

providers {
  aws = ["~> 1.38"]
  null = ["~> 1.0"]
  template = ["~> 1.0"]
  terraform = ["~> 1.0"]
}

2. Create Terraform S3 backend

# create_backend: Create Terraform S3 backend
docker run --rm -it \
    -e BACKEND_S3_REGION=ap-northeast-2 \
    -e BACKEND_S3_BUCKET=your-bucket-name \
    ridibooks/tfenv \
    create_backend

# delete_backend: Delete Terraform S3 backend
docker run --rm -it \
    -e BACKEND_S3_REGION=ap-northeast-2 \
    -e BACKEND_S3_BUCKET=your-bucket-name \
    ridibooks/tfenv \
    delete_backend

3. Run Terraform commands

# Commands:
#  - init [TARGET_PATH]
#  - plan [TARGET_PATH]
#  - apply [TARGET_PATH]
#  - get [TARGET_PATH]
#  - destroy [TARGET_PATH]
#  - output [TARGET_PATH]
#  - state [TARGET_PATH] [COMMAND]
#  - import [TARGET_PATH] [RESOURCE_ADDR] [ID]
#  - force-unlock [LOCK_ID]

# Example: terraform init
docker run --rm -it \
    -e BACKEND_S3_REGION=ap-northeast-2 \
    -e BACKEND_S3_BUCKET=your-bucket-name \
    -v /your/project/root:/app
    ridibooks/tfenv \
    init prod/resource1
