# Apache Kafka (Experimental)
|
|
|
|
### Info:
|
|
|
|
This template creates, scale in and scale out a multinodes kafka broker cluster on top of Rancher. The configuration is generated with confd from Rancher metadata.
|
|
Cluster size are variable after deployment, and get reconfigured after refresh interval.
|
|
|
|
|
|
### Usage:
|
|
|
|
Select Apache Kafka from catalog.
|
|
|
|
Enter the number of nodes, mem and refresh interval for the kafka cluster.
|
|
|
|
Change the following kafka default parameters, if you need:
|
|
|
|
- kafka_scale=3 # kafka scale to deploy.
|
|
- kafka_mem=512 # kafka broker memory.
|
|
- kafka_log_dir="/opt/kafka/logs" # Kafka log dir.
|
|
- kafka_log_retention="168" # kafka log retention.
|
|
- kafka_num_partitions="1" # Kafka partitions number
|
|
- kafka_delete_topics="false" # kafka delete topics
|
|
- kafka_pub_ip= < true | false > # Advertise public ip to zookeeper.
|
|
- zk_link="kafka-zk/zk" # zookeeper stack/service to connect to.
|
|
|
|
Click deploy.
|
|
|
|
Kafka can now be accessed over the Rancher network.

|
|
|
Note: When you scale the cluster, zero downtime is not guaranteed..yet..
