Questions about community version cp-ansible

[ChenZhaobin]

Qustion1: How to clean hosts deployed by cp-ansible? After I run the command :" yum remove $(yum list installed | grep 'confluent' | awk '{ print $1}') ",the data in kafka still exists,and some services still running such as control center . Qustion2: How to down grade enterprise version to community version Question3 : what will happen if I deployed using enterprise version ,and time expired ,will everything works fine except control-center? Question4: what the differents between opensource kafka and community version of confluent-kafka? Are they using the same source code or not?

For the first question, I solved it by running below command:

yum remove $(yum list installed | grep 'confluent' | awk '{ print $1}')  &&  \

rm -rf /var/lib/confluent&& \
rm -rf /var/lib/kafka&& \
rm -rf /var/lib/kafka-streams &&  \
rm -rf /var/lib/zookeeper &&  \

rm -rf /etc/kafka&& \
rm -rf /etc/kafka-rest &&  \
rm -rf /etc/confluent-control-center && \
rm -rf /etc/confluent-metadata-service&&  \
rm -rf /etc/confluent-rebalancer &&  \

rm -rf /var/log/confluent/&& rm -rf /var/log/kafka/ &&  \

rm -rf /etc/systemd/system/confluent-zookeeper.service.d && \
rm -rf /etc/systemd/system/confluent-kafka.service.d && \
rm -rf /etc/systemd/system/confluent-kafka-rest.service.d && \
rm -rf /etc/systemd/system/confluent-server.service.d && \
rm -rf /etc/systemd/system/confluent-schema-registry.service.d && \
rm -rf /etc/systemd/system/confluent-kafka-connect.service && \
rm -rf /etc/systemd/system/confluent-control-center.service.d && \
rm -rf   /usr/lib/systemd/system/confluent-zookeeper.service &&  \
rm -rf   /usr/lib/systemd/system/confluent-kafka.service && \
rm -rf   /usr/lib/systemd/system/confluent-kafka-rest.service && \
rm -rf   /usr/lib/systemd/system/confluent-server.service &&\
rm -rf  /usr/lib/systemd/system/confluent-schema-registry.service.d&&\

Hello @ChaoqunCHEN to answer your questions:

2. You can choose which version of Confluent platform you wish to install via the inventory file as outlined here: https://github.com/confluentinc/cp-ansible/blob/6.1.1-post/hosts_example.yml#L113
3. If the 30 day trial expires, then various components will fail to work, including the brokers, as Confluent-Server contains a lot of extra features that are not available in Confluent-Kafka.
4. Confluent Server builds on top of Confluent Kafka (Full Open source) to add additional features which require a license. It's an OpenCore model.

You can find more details here: https://docs.confluent.io/platform/current/platform.html#cp-vs-ak-key-differences

Thanks for the questions!
