Automating EC2 creation - Stopping - Starting using Ansible

 

Requirements

Requirements (on host that executes modules):

1. python 3
2. awscli
3. boto - Ansible will connect to AWS using the boto SDK. So, we need to install the boto and boto3 packages. :

   $ pip3 install boto boto3

add this configuration to the ansible hosts file

Here is the hosts file:

[local]
localhost ansible_python_interpreter=/usr/share/python3   

you can fallow below commands ro find path 

root@ip-172-31-23-165:/home/ubuntu# python3 --version

Python 3.10.6

root@ip-172-31-23-165:/home/ubuntu# whereis python 3

python: /usr/share/python3

Note that we set the ansible_python_interpreter configuration option to /usr/share/python3. The ansible_python_interpreter configuration option is usually set per-host as an inventory variable associated with a host.

EC2 Creation 

create a file named ec2-creation.yml 

---

- name: stop EC2 instance

  hosts: all

  gather_facts: yes

  vars:

      region: us-east-1

      instance_type: t2.nano

      ami: ami-08c40ec9ead489470  # Ubuntu 20.04 LTS

      keypair: Laptop # pem file name

      subnetid: subnet-057cf54a81b45d203

  tasks:

    - name: Create an ec2 instance

      ec2:

         key_name: "{{ keypair }}"

         group: default  # security group name

         instance_type: "{{ instance_type }}"

         image: "{{ ami }}"

         wait: true

         region: "{{ region }}"

         count: 1  # default

         count_tag:

            Name: Demo

         instance_tags:

            Name: Demo

         vpc_subnet_id: "{{ subnetid }}"

         assign_public_ip: yes

         state: stopped

      register: ec2

      

      

execute this playbook 

anisble-playbook ec2-creation.yml 

EC2 Stopping 

create the playbook named ec2-stop.yml

 

- name: stop EC2 instance

  hosts: all

  gather_facts: yes

  vars:

    instance_ids:

      - 'i-0aca0590e709cc531'

    region: us-east-1

  tasks:

    - name: Stop the sandbox instances

      ec2:

        instance_ids: '{{ instance_ids }}'

        region: '{{ region }}'

        state: stopped

        wait: True

        vpc_subnet_id: subnet-057cf54a81b45d203

        assign_public_ip: yes

Execute them same way using command 

ansible-playbook ec2-stop.yml

EC2-Starting 

create the playbook named ec2-start.yml

- name: stop EC2 instance

  hosts: all

  gather_facts: yes

  vars:

    instance_ids:

      - 'i-0aca0590e709cc531'

    region: us-east-1

  tasks:

    - name: Stop the sandbox instances

      ec2:

        instance_ids: '{{ instance_ids }}'

        region: '{{ region }}'

        state: started

        wait: True

        vpc_subnet_id: subnet-057cf54a81b45d203

        assign_public_ip: yes

Execute them same way using command 

ansible-playbook ec2-start.yml
