Start Using Terraform on a Proxmox Server

Install

From tutorial:

apt -y install lsb-release software-properties-common

Add the HashiCorp GPG key:

curl -fsSL https://apt.releases.hashicorp.com/gpg | apt-key add -

Add the repo:

apt-add-repository "deb [arch=amd64] https://apt.releases.hashicorp.com $(lsb_release -cs) main"

Install Terraform:

apt update && apt install -y terraform

Use API-keys for Authentication

1. Create a datacenter user. In the Datacenter/Permissions/User add, e.g. alex, realm: Linux PAM.

2. Verify in Proxmox console using pveum user list

3. Create a new API token. In the Datacenter/Permissions/API Tokens, add:

• user: alex@pam
• token id: new_token_id
• privilege separation: unchecked
• Secret fuji: ebf02232-ec86-480c-acdf-4e83fed2c2e6
• Secret suprox: edf8b941-c633-48f2-bc70-9bf5dea85668

1. add a role PVEAdmin to the newly created user alex: pveum acl modify / --roles PVEAdmin --users alex@pam

• user permission - Path=/storage/local-lvm, User=asokolsky@pam, Role=Administrator, Propagate=true

Partner and community providers are signed by their developers.
If you'd like to know more about provider signing, you can read about it here:
https://www.terraform.io/docs/cli/plugins/signing.html

Terraform has created a lock file .terraform.lock.hcl to record the provider
selections it made above. Include this file in your version control repository
so that Terraform can guarantee to make the same selections by default when
you run "terraform init" in the future.

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
