Goal: Learn how to create Container Group resources on Azure using Terraform.

Explanation

Azure can host containers for you, taking away the need to maintain your own infrastructure.

Howto

Use azurerm_container_group to spin up a few containers.

Demo

See this example repository.

Assignment

• Use the example mentioned in the documentation.

Once applied, the container group gets an IP address. (See the Azure portal)

The terraform code in the documentation show what port you may visit.

• Try to visit the IP address. (https://IP_ADDRESS/)

This does not work. Inspect the Azure Portal to understand what’s wrong. (Hint below, but give yourself time to figure it out.)

• Fix the problem by changing the Terraform code.
• Apply again and try to visit the IP address.

You should now have a working website. Let’s reduce the allocated memory and CPU, and likely save a bit of money.

• Check in the Azure Portal how much memory the containers use.
• Change the memory parameter to 0.1 for both containers and apply the code.

Questions

1. Do you see a use-case for your situation to use container groups?
2. Does each container have a unique IP-address?
3. What does your container group cost per month?

Hints

• The port used in the Terraform code example is 443, but the container just exposes 80.
