To install the terraform command in linux ubuntu I sent these commands to work in my virtual box machine:

terraform plan
sudo snap install terraform
sudo apt install terraform
sudo apt update && sudo apt install -y gnupg software-properties-common curl
curl -fsSL https://apt.releases.hashicorp.com/gpg | sudo gpg --dearmor -o /usr/share/keyrings/hashicorp-archive-keyring.gpg
echo "deb [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 -y terraform

Example Project with OpenStack: Video Tutorial

git clone https://github.com/hasanashik/openstack-terraform

cd openstack-terraform

terraform init

terraform plan

terraform validate

terraform apply

SOLUTION: Find the controller ip address:

openstack endpoint list

Got error:  Missing value auth-url required for auth plugin password
solultion:
$ source /opt/stack/devstack/openrc admin admin

 If successful, look for the Service Type: identity and the Interface: public row. That URL is your controller's main API address.
