About this Hands-on Lab

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.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

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
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
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

Additional Resources

Notice: Ansible is installed as the root user, so please work on all tasks after elevating to the root user.

You received a ticket to upgrade the application and database for servers in your environment. There is an index.html and deploy.sh script in the /root directory on your Ansible Host. Write a playbook that deploys the index.html file to the webserver (in /var/www/html/), then deploys deploy.sh script to the dbserver in /opt, and finally executes that deploy.sh script. Use curl to test your deployment.

Once that deployment has finished, your developers let you know they found and fixed a major bug, and this fix needs to be deployed immediately. Deploy the /root/index2.html file to address this issue.
