Deploy Secure Confluent Platform Docker Images

Confluent Platform supports cluster encryption and authentication, including a mix of authenticated and unauthenticated, and encrypted and non-encrypted clients. Using security is optional. These security features are supported on the Confluent Platform Docker images:

Component Feature
Confluent Control Center HTTPS
Kafka Connect None
Schema Registry HTTPS
ZooKeeper SASL

For details on the available security features in Confluent Platform, see the Confluent Platform Security Overview Documentation.

Manage secrets

When you enable security for the Confluent Platform, you must pass secrets such as credentials, certificates, keytabs, Kerberos configuration, and more to the container. The images handle this by expecting the credentials to be available in the secrets directory. The containers specify a Docker volume for secrets and expect the administrator to map it to a directory on the host that contains the required secrets. For details about how to configure secrets protection in Docker containers, refer to Configuring secrets for Docker.
