Terraform: Deploy VM

Description

After following “Create Terraform Service Principle”, I did the following to deploy a VM following the official guide here.

To Resolve:

1. Since cloudshell already has Terraform cli installed, I just did the following in cloudshell Bash:

   # first, make sure environmental vars are populated from previous steps (see reference to previous post)
   printenv | grep ^TF_VAR*
   
   cd clouddrive
   mkdir terra
   cd terra
   

2. Upload main.tf using the upload tool.

3. Now we just run a series of commands using terraform cli:

   # Init and install modules
   terraform init
   
   # Create a plan => Tells you what actions it will do like create resources but doesn't do it
   terraform plan -out main.tfplan
   
   # Apply the plan => Creates resources
   terraform apply main.tfplan
   

4. SSH into the VM

   terraform output -raw tls_private_key
   # Copy/paste to c:\scripts\key.txt
   
   # now open powershell and type:
   wsl
   cp /mnt/c/scripts/key.txt /home/gerry/key.txt
   
   mv /home/gerry/key.txt /home/gerry/mykey
   chmod 400 mykey
   # replace the IP on next step with public IP of your Ubuntu VM
   ssh -i ./mykey azureuser@13.90.207.214
   
   # notice I can ssh in with key and also have root access, 'sudo su' for example
   

5. Now that we have deployed an environment, let’s tear it down to not incur any costs:

   terraform plan -destroy
   terraform apply -destroy
