Create an Ansible playbook to launch the EC2 instance and configure minikube in it

Prerequisites:

• Ansible Installed
• Inventory Configured
• AWS CLIv2 installed and Configured

Step-1)Configuring Dynamic inventory

• Here I am using dynamic inventory because we have to configure minikube in ec2 instance.
• For the dynamic inventory, download ec2.py and ec2.ini from this given URL, and paste in the inventory folder:

https://github.com/ansible/ansible/tree/stable-2.9/contrib/inventory

• Now add this path in ansible.cfg
• After that, you also need to copy the key.pem for the ec2 instance launch.
• After copying your key, make it executable by the following command:

chmod 600 Key_Name.pem

• Here you also need privilege escalation because in aws we have to configure all the configurations done by the user root only.
• After this edit your ec2.py

• change your python path in my case it is /usr/bin/python3.
• Save it.
• After this make this file executable by the following command:

chmod +x ec2.py

Step-2)Launching ec2 instance

- hosts: localhost
  tasks:
  - name: Launching OS
    ec2:
      key_name: key
      instance_type: t2.medium
      image: ami-04b1ddd35fd71475a
      wait: yes
      count: 1
      instance_tags:
        Name: k8s_minikube
      vpc_subnet_id: subnet-c08fce8c
      assign_public_ip: yes
      region: ap-south-1
      state: present
      group_id: sg-011aaeeafb6ee8fff

• Here u need to add some info for launching aws ec2 instance like key_name, ami_id,vpc name, etc.

Step-3)Configuring minikube in ec2 instance

- hosts: tag_Name_k8s_minikube
tasks:
  - name: conf repo for kubectl
    yum_repository:
      name: Kubernetes
      description: Kubectl
      baseurl: https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64
      gpgcheck: yes
      gpgkey: https://packages.cloud.google.com/yum/doc/yum-key.gpg https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
      repo_gpgcheck: yes

• The first step is to setup the repo.

- name: Installing kubectl
    yum:
      name: kubectl
      state: present- name: Installing Docker
    yum:
     name: docker
     state: present- name: Installing conntrack
    yum:
      name: conntrack
      state: present

• Here I am installing kubectl(we have already setup a repo), we need docker because minikube needs docker, conntrack because if u don’t install it’ll not start minikube.

- name: Downloading minikube
    get_url:
      url: https://storage.googleapis.com/minikube/releases/latest/minikube-latest.x86_64.rpm
      dest: /root/minikube-latest.x86_64.rpm- name: Installing minkube
    yum:
      name: /root/minikube-latest.x86_64.rpm
      state: present- name: Starting Minikube driver using none
    command: minkube start --driver=none

• The final setup is to installing minikube I use get_url to download minikube, and after yum for installing, at last, minikube start — — driver=none (driver=none because we are going to install minikube on the top of os without using any driver like(Virtualbox, etc).

Output

ec2 instance launched

minikube installed
