This repo contains code to provision infrastructure in AWS and runs a Kafka cluster of 3 nodes there. Terraform creates instances in VPC, which are available from admin IP only. Ansible installs Zookeeper and Kafka through Bastion.

Fulfill the following manual steps to prepare local environment to provision infrastructure:

• Create AWS Elastic IP resource for bastion instance and assign its Allocation Id to TF_VAR_ec2_bastion_eip_id environment variable
• Generate AWS Key Pairs to access EC2 instances with SSH and assign its Name to TF_VAR_ec2_ssh_key_name environment variable
• Take IP address of your machine and assign it to TF_VAR_admin_static_ip environment variable

From ./provision directory run terraform apply -auto-approve, or make provision.

To prepar Kafka configuration code move to ./configure directory and run the following:

• Install cp-ansible collection by running ansible-galaxy install -r requirements.yml
• Copy ssh.example.cfg to .ssh.cfg (with mv ssh.example.cfg .ssh.cfg for ex.) and replace: {bastion.example.com} with bastion public DNS address (can be taken from Terraform output); {path-to-ec2-ssh-key} path to created earlier AWS Key Pairs

To run the code execute make configure or:

• Ensure Ansible can connect to all the node instances by running ansible all -m ping
• Run installation and configuration ansible-playbook confluent.platform.all --tags=zookeeper,kafka_broker

After launch is finished successfully, run kafkacut to query Kafka metadata from instances:

docker run --rm -t confluentinc/cp-kafkacat kafkacat -b {node_public_dns}:9092 -L -J
