This repository can be used to spin a Kubernetes cluster on DigitalOcean with very little effort. The overall flow is taken from Janakiram MSV's tutorial
- Clone this repository
- Generate a Kubeadm token using following command:
python -c 'import random; print "%0x.%0x" % (random.SystemRandom().getrandbits(3*8), random.SystemRandom().getrandbits(8*8))' - Create a file called terraform.tfvars with following content:
do_token = "YOUR_DIGITALOCEAN_TOKEN"
# Generate a new token via following command line:
# python -c 'import random; print "%0x.%0x" % (random.SystemRandom().getrandbits(3*8), random.SystemRandom().getrandbits(8*8))'
#
k8s-token = "USE_TOKEN_FROM_PREVIOUS_STEP"
#
# Location of public and private key files
#
private_key_file = "ssh/harshal-ic.ppk"
public_key_file = "ssh/harshal-ic-pub.txt"
- Run
terraform apply. Once the process finishes, 1 master and 2(default) workers will be created and admin.conf to work with kubernetes cluster will get copied to the PWD location.
Note: Variables defined in variables.tf can be overwritten by updating them in terraform.tfvars
- Once the process finishes, run following command to work with your kubernetes cluster:
kubectl --kubeconfig ./admin.conf get nodes
