Hands on 3 - Deploying
The goal of this hands-on is to:
- deploy Flatcar instances with IaC (Terraform)
- manipulate Terraform code
- write Flatcar provisioning with Terraform
- deploy Flatcar on OpenStack with Terraform
This is a bundle of hands-on-1 and hands-on-2 but it’s not a local deployment and everything is as code.
git clone https://github.com/tormath1/flatcar-tutorial; cd flatcar-tutorial/hands-on-3 # go into the terraform directory cd terraform # update the config for creating index.html from previous hands-on vim server-configs/server1.yaml # init the terraform project locally terraform init # get the credentials and update the `terraform.tfvars` consequently # generate the plan and inspect it terraform plan # apply the plan terraform apply # go on the horizon dashboard and connect with terraform credentials # find your instance
One can assert that it works by accessing the console (click on the instance then “console”)
NOTE: it’s possible to SSH into the instance but at the moment, it takes a SSH jump through the openstack (devstack) instance.
ssh -J user@[DEVSTACK-IP] -i ./.ssh/provisioning_private_key.pem -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null core@[SERVER-IP]
To destroy the instance:
# if you are happy, destroy everything terraform destroy
