Full list of KafkaClientAuthenticationPlain schema properties
To configure SASL-based PLAIN authentication, set the type property to plain. SASL PLAIN authentication mechanism requires a username and password.
The SASL PLAIN mechanism will transfer the username and password across the network in cleartext. Only use SASL PLAIN authentication if TLS encryption is enabled.
77.1. username
Specify the username in the username property.
77.2. passwordSecret
In the passwordSecret property, specify a link to a Secret containing the password.
You can use the secrets created by the User Operator.
If required, create a text file that contains the password, in cleartext, to use for authentication:
echo -n PASSWORD > MY-PASSWORD.txt
You can then create a Secret from the text file, setting your own field name (key) for the password:
oc create secret generic MY-CONNECT-SECRET-NAME --from-file=MY-PASSWORD-FIELD-NAME=./MY-PASSWORD.txt
Example Secret for PLAIN client authentication for Kafka Connect
apiVersion: v1 kind: Secret metadata: name: my-connect-secret-name type: Opaque data: my-password-field-name: LFTIyFRFlMmU2N2Tm
The secretName property contains the name of the Secret and the password property contains the name of the key under which the password is stored inside the Secret.
Do not specify the actual password in the password property.
