Step 10: Full workflow when performing updates to web apps - Alex-Burgess/ansible-demo GitHub Wiki

Placeholder - describe how to create a branch, make changes, process to merge back into master. Include how changes get deployed to staging and production. Update once final pipeline is in place.

Initial notes on how to create a branch, etc.

1. Create and checkout a new git branch on local machine:

   $ git checkout -b poc-site-features
   

2. Make changes to web content. e.g. edit index.html:

   vi index.php
   ...
   <font>new content</font>
   ...
   

3. Test content on local machine. Run php server and browser to index.php.

   php -S localhost:8000
   

4. Commit changes to git on local machine:

   $ git add helloworld.com/httpContent/html/index.html
   $ git commit -m "Updating content of index.html"
   

5. Push changes to remote branch:

   $ git push -u origin poc-site-features
   

6. On test Ansible controller, run playbook to deploy changes to web servers:

   $ sudo -i -u ansible
   $ cd /app/ansible/AnsibleWebDeployment
   $ ansible-playbook -i inventories/testing/webappA_hosts main.yml -e "git_branch=poc-site-features"
   

7. Test load balancer url in browser: http://ansiblehelloworld-test-lb-1998216944.eu-west-1.elb.amazonaws.com/
