This is the script to create cluster in Digital Ocean (DO).

1. Droplet bootstrap script

There are 2 files in droplet-u22, which used for droplet ubuntu 22.10. After creating Droplets, SSH to Droplets and run these script as the role below:

control-plane.sh
worker.sh

You can run the fast script using this command:

git clone https://github.com/kumcp/k8s_learning_example.git
cd ./k8s_learning_example/
git checkout develop
cd ~
sh ./k8s_learning_example/dotest/droplet-u20/control-plane.sh

2. Terraform script

To start cluster with terraform script, you will need to follow these steps:

Step 1: Create an API keys in your DO account:

Go to your project -> Click on API -> Tokens -> Generate new Tokens -> Copy the new token generated

Step 2: Config API Key for project

Option 1: Assign key directly into project. (This is fast, but it is not recommended in the production project)

File terraform.tfvars can be created from terraform.tfvars.example. Using this command inside ./self-manage-cluster:

cp terraform.tfvars.example terraform.tfvars

Make changes to newly created terraform.tfvars file.

do_token = "<input your api key here>"

Option 2: Using environment variables:

You can use this command in your environment

export DIGITALOCEAN_ACCESS_TOKEN=<your-token-here>

Step 3: Generate terraform project inside this folder and you can create cluster:

terraform init
terraform apply
