Role Name

This is a role which will configure Slave Node of a Multi Node Kubernetes Cluster on Public Cloud. Here, I have used AWS as my Public Cloud Provider.

Requirements

Requirements for these are: 1.) Pre-created Instanes 2.) 2 files: ec2.py script and ec2.ini file 3.) Public Key, attached to these Instances 4.) Master Node pre-Configured with it's token saved in a file.

Role Variables

There are various Variables used in this role: docker_repo_url: This is used to take Docker Repo URL docker_pkg: This will take the name of the docker package docker_svc: Service Name of Docker k8s_repo_url: Kubernetes Repo URL k8s_gpg_url: Gpgkey URL, may be used in OS other than Centos(like Redhat). k8s_repo_pkg: List of Kubernetes Packages to install docker_driver_path: Path of file to change the driver warning2_pkg: iproute-tc Package cidr_range: Range of Pods k8s_conf_path: Kubernetes Configuration Path k8s_dir_path: Kubernetes Directory Path flannel_url: Url to install flannel file_dest: Path to file in which token is stored.

Dependencies

Generally, no dependency is there internally, but it is preferrable to use my Master role for configuring Master first and then by adding this role also in the same play to a SLave host will be much preferrable to do. Otherwise If you have all the Requirements fullfilled, then just run this role in a play.

Example Playbook

• hosts: tag_Name_Slaves ignore_errors: yes
  become: yes vars_files: - vars.yml roles: - slave
