Lab 4.0: Ansible

Summary

This lab was very interesting I want to understand Ansible more thought because I feel I don’t fully understand it.

Ansible Commands and Steps

• sudo apt install ansible sshpass python3-paramiko - This installs all dependencies and ansible
• Make user with the same passwork to be used as deployer
• keygen -t rsa -C <user>
• ssh-copy-id -i ~/.ssh/mykey.pub <user>@<host>
• vi /etc/sudoers.d/sys265 - to look like the following | this allows a user to enter sudo without password

 <user>           ALL=(ALL)           NOPASSWD: ALL

• Now create inventory.txt if applicable make this in a dir called ansible

[role_name]
<host_ip> or <hostname>

• ansible all -m ping -i inventory.txt - This is an easy way to test if the inventory is setup right
• ansible-galaxy install <package> -p <dir>/ - This is used to install packages for ansible
• ansible-playbook -i invetory.txt <dir>/<path.yml>

My Playbook for java

• ansible-galaxy install gantsign.java

- hosts: java
  roles:
         - roles: gantsign.java
