Kafka CentOS cluster deployment

Use Ansible playbook to create Kafka cluster on remote machines.

Originally forked from git@github.com:lloydmeta/ansible-kafka-cluster.git.

Usage

1. Install the dependencies on your machine

For Mac, this can be done with Homebrew:

brew install ansible

For Ubuntu, use apt:

sudo apt-get install ansible

Make sure you are running Ansible v2.1 or higher with ansible --version. Ansible documentation.

2. Clone this repository

git clone git@github.com:ScreamingUdder/ansible-kafka-centos.git
cd ansible-kafka-centos

3. Prepare cluster machines

Cluster machines should have CentOS installed and sshd running. The playbook expects to have access over ssh to root.

4. Configure host names

If you are deploying to physical machines then put the required host names in hostname_vars.yml and hosts.ini.

5. Change version numbers

If you want different versions of Java, Kafka or Zookeeper then change the variables in the defaults/main.yml file for each role.

6. Update Conan template

If you are deploying a Conan.io server, don't forget to update the secrets and user details in /roles/conan/templates/server.conf.j2.

7. Update passwords

If you want to change the default passwords for things before deploying, do so manually. Do not push these to the git repository!

8. Run the playbook!

To deploy use:

ansible-playbook --inventory-file=hosts.ini site.yml

It can be useful to ignore your ssh known hosts:

export ANSIBLE_HOST_KEY_CHECKING=False
