Demo of Terraform, Ansible and Kubespray integration

With the code in this repository you can deploy kubernetes cluster on top of GIG Edge Cloud

This consists of

• terraform configuration to manage the cloudspaces and create the virtual machines
• ansible configuration for the virtual machines
• kubespray configuration to deploy the kubernetes cluster
• ansible playbook to install persistent volume for the kubernetes cluster

** ansible ( >= 2.8.0) ansible installation guide

Using this repository

Import submodule:

git config --global status.submoduleSummary true
git submodule init
git submodule update

Requirements:

• Itsyou.online account (retrieve a client ID and client secret and get a JWT) (https://github.com/gig-tech/terraform-provider-ovc#authentication)
• Necessary permissions on a G8 (cloudspace account), that is linked to your Itsyou.online account
• Edit terraform/terraform.tfvars as needed (may need to update account and server_url)
• The terraform-inventory script: https://github.com/nbering/terraform-inventory/ , already provided in the repo
• The ansible provider plugin https://github.com/nbering/terraform-provider-ansible , download the latest release and put the file at ~/.terraform.d/plugins/terraform-provider-ansible
• The OVC provider plugin https://github.com/gig-tech/terraform-provider-ovc, download the latest release and put the file at ~/.terraform.d/plugins/terraform-provider-ovc
• Your ssh public key will be added when deploying with Terraform

Before starting update Terraform configuration in config.env file with your own data. You can also add Terraform variables to terraform/terraform.tfvars. It is important that server_url, client_jwt and account are given as environmental variables, as they are used in further steps.
