Docker Security for Confluent Platform

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	Tests
Confluent Control Center	HTTPS
Kafka Connect	None
Kafka	SASL, SSL
REST Proxy	HTTPS
Schema Registry	HTTPS
ZooKeeper	SASL

Managing secrets

When you enable security for the Confluent Platform, you must pass secrets (e.g., credentials, certificates, keytabs, Kerberos configiguration, etc.) 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 admin 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.

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