Dockerfile of Kafka with consul template

Kafka with consul-template

How to run:

docker run -d --name kafka -p 9200:9200 -v /home/core/shared/templates/kafka-templates:/templates --label SERVICE_NAME=kafka --dns=172.17.9.101 --dns-search=service.consul stakater/kafka-with-consul-template

Note:

• The --dns option must specify the address of the consul agent, which will be the private IP of the host instance/machine. (usually it can be founded by the hostname -i command)
• Provide the volume mapping (-v) if you want to use a custom template for kafka. If the one provided in this repo is enough for your use, you can skip this mapping.

Sample Template

We have provided a sample template (in the templates directory).

To be able to use that template, you must make sure the following preconditions are met:

Preconditions

Consul services:

• You must have atleast 1 zookeeper service running registered in consul by the name zookeeper-2181

You can run zookeper as follows:

docker run -d --name zookeeper --label SERVICE_NAME=zookeeper -p 2181:2181 zookeeper

Consul Key-Value entries:

1. The host required to tell clients where to find the broker as well as to communicate with the broker itself.

   key: kafka/advertisedHost

   Example: 172.17.9.101

   Usually this would be the private IP of the instance/machine that is running kafka

2. The port for the advertised host.

   key: kafka/advertisedPort

   Example: 9200

   This port must be same as the one exposed during running the docker container
