Challenge
Generate an encryption key and include it in a Kubernetes data encryption config file.
To accomplish this task, do the following on the workspace server:
ENCRYPTION_KEY=$(head -c 32 /dev/urandom | base64) cat > encryption-config.yaml << EOF kind: EncryptionConfig apiVersion: v1 resources: - resources: - secrets providers: - aescbc: keys: - name: key1 secret: ${ENCRYPTION_KEY} - identity: {} EOF -
Challenge
Copy the file to the Kubernetes controller servers.
Copy
encryption-config.yamlto each Kubernetes controller by running these commands from the workspace server. Be sure to replace the placeholders with the actual IP addresses of the controller servers.scp encryption-config.yaml cloud_user@<controller 1 public ip>:~/ scp encryption-config.yaml cloud_user@<controller 2 public ip>:~/
