# About
This shows how to create a [Azure Container Instances Container Group](https://docs.microsoft.com/en-us/azure/container-instances/container-instances-container-groups) with [Caddy (for Let's Encrypt TLS Certificate)](https://hub.docker.com/_/caddy) reverse proxy for an internal test container.
This is wrapped in a vagrant environment to make it easier to play with this stack without changing your local machine.
## Usage
If you are using Hyper-V, [configure Hyper-V in your local machine](https://github.com/rgl/windows-vagrant#hyper-v-usage).
If you are using libvirt, you should already known what to do.
Start the vagrant environment:
```bash
vagrant up --no-destroy-on-error
```
Enter the created vagrant environment and play with the example terraform project:
```bash
# enter the vagrant environment.
vagrant ssh
# login into azure.
az login
# list the subscriptions.
az account list --all
az account show
# set the subscription.
export ARM_SUBSCRIPTION_ID=""
az account set --subscription "$ARM_SUBSCRIPTION_ID"
# provision the example infrastructure.
cd /vagrant
export CHECKPOINT_DISABLE=1
export TF_LOG=TRACE
export TF_LOG_PATH=terraform.log
terraform init
terraform plan -out=tfplan
time terraform apply tfplan
# use the app.
wget -qSO- "$(terraform output -raw url)"
# show the app logs.
# NB to show all the containers logs omit --container app.
az container logs \
--resource-group rgl-terraform-container-instances-example \
--name example \
--container app \
--follow
# destroy the infrastructure.
terraform destroy
```
## Caveats
* [There is no way to known the end-user client IP address](https://feedback.azure.com/d365community/idea/c81db3f3-0c25-ec11-b6e6-000d3a4f0858).
* **NB** The ACI container is behind a load balancer that does not preserve the client IP address.
