IAC Kubernetes cluster

• The terraform modules create supporting infrastructure for a kube cluster like VPC's, RDS, Peering connection, bucket etc
• The create_cluster script uses the kOps library to setup kube cluster configuration into terraform which can then be applied onto previously created resources

To set up networking and other aws resources:

cd main

Change variables in terraform.tfvars

terraform init
terraform plan
terraform apply

Note: The values for cluster configuration can be shown through terraform output *after resources are set up

For setting up the cluster:

cd cluster
export AWS_PROFILE=kops_user

bash create_cluster.sh [-n cluster_name] [-v vpc_id] [-b bucket_name] [-c new-key-path] [-e existing-public-key-path] [-s public-subnets] [-p private subnets]

This will generate tf file into the current folder, to apply the cluster resources:

terraform init
terraform plan
terraform apply

Validating cluster:

kops validate cluster --state=s3://<BUCKET_NAME> --name=<CLUSTER_NAME> --wait 10m
