Versions

• Module tested for Terraform 1.0.1.
• GCP provider version 4.11.0.
• main branch: Provider versions not pinned to keep up with Terraform releases.
• tags releases: Tags are pinned with versions (use ).

Usage

Option 1:

terrafrom init
terraform plan -var='teamid=tryme' -var='prjid=project1'
terraform apply -var='teamid=tryme' -var='prjid=project1'
terraform destroy -var='teamid=tryme' -var='prjid=project1'

Note: With this option please take care of remote state storage

Option 2:

Recommended method (stores remote state in S3 using prjid and teamid to create directory structure):

• Create python 3.8+ virtual environment

python3 -m venv <venv name>

• Install package:

pip install tfremote --upgrade

• Set below environment variables:

export TF_GCLOUD_BUCKET=<remote state bucket name>
export TF_GCLOUD_PREFIX=<remote state bucket prefix>
export TF_GCLOUD_CREDENTIALS=<gcp credentials.json>

• Updated examples directory with required values.

• Run and verify the output before deploying:

tf -c=gcloud plan -var='teamid=foo' -var='prjid=bar'

• Run below to deploy:

tf -c=gcloud apply -var='teamid=foo' -var='prjid=bar'

• Run below to destroy:

tf -c=gcloud destroy -var='teamid=foo' -var='prjid=bar'
