Terraform module to create Azure Virtual Network

Versions

• Module tested for Terraform 1.0.1.
• Azure provider version 2.90.0
• main branch: Provider versions not pinned to keep up with Terraform releases
• tags releases: Tags are pinned with versions (use in your releases)

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 storage 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_AZURE_STORAGE_ACCOUNT=tfstatexxxxx # Output of remote_state.sh
export TF_AZURE_CONTAINER=tfstate # Output of remote_state.sh
export ARM_ACCESS_KEY=xxxxxxxxxx # Output of remote_state.sh

• Updated examples directory to required values

• Run and verify the output before deploying:

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

• Run below to deploy:

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

• Run below to destroy:

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