Setting up Kafka Connect, cannot rename group ID

QUESTION

Setting up Kafka Connect, cannot rename group ID

Asked 2021-Dec-04 at 15:29

I am using this Github repo and folder path I found: https://github.com/entechlog/kafka-examples/tree/master/kafka-connect-standalone

The issue I am having is that, as a matter of access control, I must specify my group ID by adding a prefix to it, let's call it abc-. When I build this Docker image, I check my logs and I can see that the group ID ends up being connect-bq-sink-connector, which I am assuming is a concatenation of the word connect- along with the variable CONNECTOR_NAME seen in the docker-compose file. When I change the connector name variable, my group ID also changes (but the connect- prefix always remains). You will also see a variable called CONNECT_GROUP_ID in the docker-compose file. This variable appears to have absolutely no effect on the Kafka connect instance. The Docker logs give this (in this order):

WARN The configuration 'group.id' was supplied but isn't a known config. (org.apache.kafka.clients.admin.AdminClientConfig:380)

and then later...

...

group.id = connect-bq-sink-connector

The final error, which is mostly unimportant as I know it is due to lack of permissions, is simply:

...

If you want to change connect group id, add environment variable name CONNECTOR_ properties section under the service kafka-connect and set a value you want.

The github example starting steps as follows.

In file docker/Dockerfile, a startup command is /etc/confluent/docker/run and you cant find the file in docker/include/etc/confluent/docker.
Start a container with simple step configure and launch in the docker/include/etc/confluent/docker/run file.
In file docker/include/etc/confluent/docker/configure, Check mandatory environment variables such as CONNECT_BOOTSTRAP_SERVERS, CONNECT_KEY_CONVERTER, CONNECT_VALUE_CONVERTER... are set, and call templating function with kafka-connect-standalone.properties.template and kafka-connect.properties.template.

So if there is a configuration that you want to add to the kafka-connect-standalone.properties file, you must specify an environment variable starting with CONNECTOR_.

You can find all configuration for kafka connect in the following link.
