# terraform.azure.automation

Terraform repository to perform automatic tasks in Azure cloud.

## Requirements
First you must have *terraform* installed on host who run your automatism.

To install *terraform*, you should have **wget** and **unzip**.
```bash
sudo apt install wget unzip
```
```bash
wget -O terraform_0.12.20_linux_amd64.zip https://releases.hashicorp.com/terraform/0.12.20/terraform_0.12.20_linux_amd64.zip \
&& wget -O terraform_0.12.20_SHA256SUMS https://releases.hashicorp.com/terraform/0.12.20/terraform_0.12.20_SHA256SUMS \
&& sha256sum --ignore-missing -c terraform_0.12.20_SHA256SUMS \
&& unzip -qn terraform_0.12.20_linux_amd64.zip \
&& mv terraform ${PATH%%:*}/ \
&& rm terraform_0.12.20_linux_amd64.zip terraform_0.12.20_SHA256SUMS 
```

To run terraform against Azure cloud, you should have Azure variable
(credentials and location) set in environment

```
$ export ARM_CLIENT_ID="00000000-0000-0000-0000-000000000000"
$ export ARM_CLIENT_CERTIFICATE_PATH="/path/to/my/client/certificate.pfx"
$ export ARM_CLIENT_CERTIFICATE_PASSWORD="Pa55w0rd123"
$ export ARM_SUBSCRIPTION_ID="00000000-0000-0000-0000-000000000000"
$ export ARM_TENANT_ID="00000000-0000-0000-0000-000000000000"
```

## Run
To run terraform, we'll use wrapper script run.sh
To run default infrastructure playbook *infra.tf* who create all the infra
```
./run.sh -v
```
To only play another state file *state.tf*
```
TERRAFORM_FILE=state.tf ./run.sh -v
```

## Docker
We'll have a Dockerfile in order to generate a docker image to use it for
running play in an controled environment.
- Build image: ```docker build -t devops-docker .```
- Run terraform using this image:
```
docker run -e "TERRAFORM_FILE=state.tf" --entrypoint "./run.sh"
devops-docker -v
```
