Using Ansible Modules to Manage File Content in Your Environment

When your web devs come up with an update to an application and you need to deploy it to 100 servers (sometimes more) doing so manually is a difficult task. While there are many ways to automate this process Ansible can handle it in addition to everything else it does. This lab will walk through a method of doing so. *This course is not approved or sponsored by Red Hat.*

Challenge

Deploy `index.html`

Your playbook should look something like:

---
- name: copy webapp
  hosts: webservers
  become: yes
   
  tasks:
   - name: install webapp
     copy:
      src: /root/index.html
      dest: /var/www/html/index.html
      owner: apache
      group: apache
      mode: 0644

Challenge

Copy and Execute the `db deploy` (deploy.sh) Script

There are two different methods of doing this in a playbook.

The first is to use script, but it is commented out. Both can be seen in this code snippet.

- name: copy db script
  hosts: dbservers
  become: yes

  tasks: 
   - name: copy deploy script
#    script: /root/deploy.sh
     copy:
      src: /root/deploy.sh
      dest: /opt/deploy.sh
      owner: root
      group: root
      mode: 0755

   - name: Execute the script
     command: sh /opt/deploy.sh

Run the playbook with this:

ansible-playbook filedeploy.yml

Challenge

Redeploy `index.html`

You should not include the db deploy in this playbook.

---

- name: copy webapp
 hosts: webservers
 become: yes

 tasks:
  - name: install webapp
    copy:
     src: /root/index2.html
     dest: /var/www/html/index.html
     owner: apache
     group: apache
     mode: 0644

Run the playbook again:

ansible-playbook filedeploy.yml
