provioning-instance-and-updating-inventory-dynamically

This is useful when we need to provision ec2-instance and configure any thing into it without updating IP in inventory file.

Pre - instruction for this tasks --->

1. Install the ansible using pip module
   #pip3 install ansible
   
2. Install sshpass software using epel release repo
   #yum install sshpass
   
3. Install boto3 library for using aws API
   #pip3 install boto3 --> for using aws_automate1.yml
   #pip3 install boto --> for using aws_automate.yml
   
4. Create directory using command - #mkdir /etc/ansible
   
5. Put the file "ansible.cfg" into /etc/ansible folder
   #mv ansible.cfg /etc/ansible --> clone the repo in root folder
   
6. Change directory by #cd /aws
   i) Edit only "aws_var.yml" and put all informations there
   ii) After modifying the "aws_var.yml" file run any of the playbook i.e., aws_automate.yml or aws_automate1.yml
   
   

Now let start -->

Provisioning EC2-instance and configuring Web Server into it

Step 1 - Provisioning EC2-Instance on the aws

• m ec2_instance:
     -a " Key_name: key_pair name
      instance_type: t2.micro
      image_id: image id which you want to launch as OS[ ami-xxxxx]
      name: "Your OS name"
      vpc_subnet_id: subnet-xxxxxx #your subnet id
      network:
         assign_public_ip: yes
      region: region name
      state: present
      security_group: sg-xxxxxxxxxxxx #your precreated security group
      aws_access_key: Your_access_keys #created from using IAM servive of aws
      aws_secret_key: your_secret_keys #created from using IAM servive of aws
  
  
  

Step 2 - Retrieving the IP and copying into the inventory file

   -m copy

Step 3 - Installing Webserver into this instance

   -m package

Step 4 - creating the webpage
   -m copy

Step 5 - Starting the httpd services
   -m service
