Cloud Shell's Terraform version is too old for slurm-on-gke

[janetkuo]

slurm-on-gke instruction recommends using Cloud Shell, which has Terraform v1.5.7, and therefore will cause errors when running terraform commands.

For example,

│ Error: Unsupported Terraform Core version
│ 
│   on .terraform/modules/cluster-1-nodepool-1/modules/gke-nodepool/versions.tf line 16, in terraform:
│   16:   required_version = ">= 1.7.4"
│ 
│ Module module.cluster-1-nodepool-1 (from git::https://github.com/terraform-google-modules/cloud-foundation-fabric.git//modules/gke-nodepool?ref=v33.0.0) does not support
│ Terraform version 1.5.7. To proceed, either choose another supported Terraform version or update this version constraint. Version constraints are normally set for good
│ reason, so updating the constraint may lead to other errors or unexpected behavior.

Users can't upgrade Terraform in Cloud Shell. Here's how I resolved it:

1. Go to the Terraform downloads page: https://www.terraform.io/downloads
2. Find the latest version for Linux (amd64).
3. In Cloud Shell, use wget to download the zip file. e.g. wget https://releases.hashicorp.com/terraform/1.10.2/terraform_1.10.2_linux_amd64.zip
4. Unzip it unzip terraform_1.10.2_linux_amd64.zip
5. Run terraform using ./terraform instead of terraform (sudo mv terraform /usr/local/bin doesn't work)

in cloudshell terminal , run below command to upgrade the terraform.

wget -O - https://apt.releases.hashicorp.com/gpg | sudo gpg --dearmor -o /usr/share/keyrings/hashicorp-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hashicorp.list
sudo apt update && sudo apt install terraform
