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.yaml to 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@&lt;controller 1 public ip>:~/
scp encryption-config.yaml cloud_user@&lt;controller 2 public ip>:~/
```
