ansible

brew install ansible

Setting up the instance

Once the AMI is created successfully, launch an instance with it and run the k8s_setup.sh script as shown below.

ubuntu@instance_local_ip~$ source k8s_setup.sh

Conclusion

When this is done, you will have access to a jenkins instance that has: awscli, kops, kubernetes, docker, docker-compose, kubectl and nginx for reverse proxy to the Jenkins server.

Running the script will also create a cluster as set in the user defined variables section. Be sure to edit this section with the appropriate variables.
