Ansible Approach

• Find all the manual steps to deploy application
• Group steps into some common activity and consider this for playbook.
• For each manual step create a task and find the right module of ansible.

Lets install an application which runs on tomcat server

• I need a linux server
  • Ubuntu 20.04
• Then execute the following commands

sudo apt update
sudo apt install openjdk-8-jdk -y
sudo apt install tomcat9 -y
wget https://referenceapplicationskhaja.s3.us-west-2.amazonaws.com/gameoflife.war
sudo cp gameoflife.war /var/lib/tomcat9/webapps/
sudo systemctl restart tomcat9.service

• Lets figure out modules
  1. apt is the command
     
  2. wget
     
  3. cp
     
  4. systemctl
