Monitoring VM

This project is an example VM defined using Terraform in CSC's Pouta service. Pouta uses openstack on the backend, therefore, this example uses openstack provider for Terraform.

Requirements

• Terraform
• git-crypt if you are the lucky one to actually deploy everything in this repository

Installation

Pouta credentials

The easiest way to obtain your credentials and allow Terraform manage your resources just download OpenStack RC File from the dropdown menu in the upeer right corner on https://pouta.csc.fi After downloading just use it like that:

-> source <project>-openrc.sh

and it will ask for your password and set your environment correctly. Remember to switch to a proper project before downloading the file.

Installations steps

To actually use everything included here, after cloning the repository unlock the secrets with

-> git-crypt unlock

If you are not a collaborator but want to test things:

• replace secrets/setup.sh with a script you want to run after deployment (or an empty file for a clean test).
• replace secrets/public_keys with a file containing you public ssh key, or an empty file if ~/.ssh/id_rsa.pub is the only key you want to use.

For clean environment on the backend, instance name is defined using an included script set-name.sh. Swift backend doesn't allow to just use variables for the backend file name, that is why we need to define it before executing Terraform.

-> ./set-name.sh kitten
Call: terraform init [-reconfigure] -backend-config=tf-backend.tfvars
-> terraform init -reconfigure -backend-config=tf-backend.tfvars

Initializing the backend...

Successfully configured the backend "swift"! Terraform will automatically
use this backend unless the backend configuration changes.

Initializing provider plugins...
- Reusing previous version of hashicorp/null from the dependency lock file
- Reusing previous version of terraform-provider-openstack/openstack from the dependency lock file
- Using previously-installed hashicorp/null v3.1.0
- Using previously-installed terraform-provider-openstack/openstack v1.35.0

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.
-> terraform apply

At the end you should see the address of your new VM like this

Outputs:

address = "128.214.254.127"
