An improved version of the project learn-terraform. In project learn-terraform, there are still several manual steps, which I hope to reduce with terraform in v2.0:

1. [done] Generate ssh key pair for mylinux
2. [done] Use multipas blueprint docker to create mylinux2 so that I don't need to
   • install docker engine
   • configure non-root user to run docker
3. Add mylinux's public ssh key to mylinux2

In this project, I'll create 2 Ubuntu virtual machines on my Windows 11 Pro laptop to practice terraform.

• mylinux
  • Ubuntu 22.04
  • runs terraform
• mylinux2
  • Ubuntu 22.04
  • docker 20.10.24
  • target machine, to be provisioned by terraform

Follow the instruction on https://multipass.run/ to install multipass on Windows 11 Pro. Or just do below in Windows Terminal.

> winget Canonical.Multipass

Issue below commands in Windows Terminal

> multipass launch -n mylinux
> multipass launch docker -n mylinux2

On mylinux

$ git clone https://github.com/zhongzhu/learn-terraform.git
$ cd learn-terraform/infra
$ terraform init
$ terraform plan
$ terraform apply

Append the content of mylinux's ~/.ssh/id_ed25519.pub to mylinux2's ~/.ssh/authorized_keys.

On mylinux

$ cd learn-terraform
$ terraform init
$ terraform plan
$ terraform apply

Below is the execution output.
