Ansible role for java 8 and its installation on CentOS 7

In our previous article, we discussed how to install java 8 on CentOS 7. Having the ability to install java 8 from a single command is a wonderous thing. So, in this post, we will see java installation using Ansible playbook or role to do just that.

Also we have already discussed regarding how to create Ansible Playbooks and Ansible Roles, so lets jump directly into the usage and examples of Ansible Roles/Playbooks.

Install Java 8 with Ansible

We have already created and submitted Ansible Role to install java 8 to Ansible Galaxy, so in this section we will see how to get download role from ansible galaxy into your work-space and how we can use it.
Install or download from Ansible Galaxy:

ansible@localhost$ ansible-galaxy install avinash6784.oracle-java -p ./roles

See Ansible Galaxy help for more options

ansible@localhost$ ansible-galaxy --help

Download from direct github:
Download manually from github like as below,

ansible@localhost$ git clone https://github.com/avinash6784/ansible-oracle-java.git

The code should reside in the roles directory of your ansible playbooks work-space. ( See ansible documentation for more information on roles ), in a folder oracle-java.
Run the playbook: 
First create a playbook like as below,

ansible@localhost$ vim test.yml
- name: Install Oracle Java
  hosts: localhost
  become: true
  roles:
    - oracle-java

ansible@localhost$ ansible-playbook -i hosts test.yml
