Self Signed Certs for MQTT Connector with TLS


How to set up Kafka Connect to deploy an MQTT connector with TLS Connection using Self Signed Certificates

Example files 

CA.crt: Root Cert with complete ca-chain needed for the connection
User.crt: User certificate
User.key: User key-pair


First locate the JVM you are using to launch Kafka Connect. If the JVM is the default system’s JVM then JAVA_HOME env will do

Then import the root cert (CA.crt) specific jvm cacerts truststore

keytool -importcert -file /path/to/CA.crt -keystore "${JAVA_HOME}/lib/security/cacerts"
