an example azure ubuntu virtual machine
# Usage (on a Ubuntu Desktop)
Install the tools:
```bash
./provision-tools.sh
```
Login into azure:
```bash
az login
```
List the subscriptions:
```bash
az account list --all
az account show
```
Set the subscription:
```bash
export ARM_SUBSCRIPTION_ID=""
az account set --subscription "$ARM_SUBSCRIPTION_ID"
```
Review `main.tf` and maybe change the `location` variable.
Initialize terraform:
```bash
make terraform-init
```
Launch the example:
```bash
make terraform-apply
```
At VM initialization time [cloud-init](https://cloudinit.readthedocs.io/en/latest/index.html) will run the `provision-app.sh` script to launch the example application.
After VM initialization is done (check the boot diagnostics serial log for cloud-init entries), test the `app` endpoint:
```bash
while ! wget -qO- "http://$(terraform output --raw app_ip_address)/test"; do sleep 3; done
while ! wget -qO- "http://[$(terraform output --raw app_ipv6_ip_address)]/test"; do sleep 3; done
```
Open a shell inside the VM, and poke it:
```bash
ssh "$(terraform output --raw app_ip_address)"
sudo cat /etc/netplan/50-cloud-init.yaml
ip addr
ip -4 route
ip -6 route
ping -6 -n -c 3 2606:4700:4700::1111 # cloudflare dns.
ping -6 -n -c 3 2606:4700:4700::1001 # cloudflare dns.
ping -6 -n -c 3 ff02::1 # all nodes. # NB does not work in azure.
ping -6 -n -c 3 ff02::2 # all routers. # NB does not work in azure.
ping -4 -n -c 3 ip6.me
ping -6 -n -c 3 ip6.me
dig -4 aaaa ip6.me
dig -6 aaaa ip6.me @2606:4700:4700::1111
curl -4 https://ip6.me/api/ # get the vm public ipv4 address.
curl -6 https://ip6.me/api/ # get the vm public ipv6 address.
curl http://ip6only.me/api/ # get the vm public ipv6 address.
curl http://10.1.1.4/test # try the app private ipv4 endpoint.
curl http://[fd00::4]/test # try the app private ipv6 endpoint.
ipv6_public_test_url="http://[$(curl -6 -s https://ip6.me/api/ | awk -F, '{print $2}')]/test"
curl "$ipv6_public_test_url" # try the app public ipv6 endpoint.
echo "go to https://dnschecker.org/server-headers-check.php and test the app ipv6 url:
$ipv6_public_test_url"
exit
```
Destroy the example:
```bash
make terraform-destroy
```
