Creating K8s Cluster

Configuring kOps Environment

1. Open the Linux shell inside the VM.

2. Set the AWS credentials (AWS access key ID and AWS secret access key) as environment variables:

   export AWS_ACCESS_KEY_ID=<your-access-key-id>
   
   export AWS_SECRET_ACCESS_KEY=<your-secret-access-key>
   

3. Set the applicable AWS region:

   export AWS_DEFAULT_REGION=<your-aws-region>
   

   e. g.

   export AWS_DEFAULT_REGION=eu-central-1
   

4. Set the S3 location in AWS for kOps to store the configuration files:

   export KOPS_STATE_STORE=s3://<your-s3-location>
   

   e. g.

   export KOPS_STATE_STORE=s3://kops-clusters.eu1.edge.siemens.cloud
   

Deploying K8s Cluster

1. Use a unique name for the K8s cluster, which must be a valid DNS name and for which you have access to the domain to configure the DNS:

   export CLUSTER_NAME=<your-cluster-name.your-DNS>
   

   e. g.

   export CLUSTER_NAME=cluster-kops.eu1.edge.siemens.cloud
   

2. Create the cluster on AWS (consider the applied AWS region):

   kops create cluster --zones eu-central-1a $CLUSTER_NAME
   

   The K8s cluster will start and should be ready in few minutes.
