ansible-web-deploy

Ansible playbooks that allow you to deploy a simple web app with apache2 web servers and haproxy load balancer.

Deploy:

1. Edit hosts_template file to specify your web servers and load balancer hosts. Replace field with your own addresses and/or add more hosts if necessary. Then run sudo mv hosts_template hosts.
2. There must be an user with NOPASSWD option in sudoers file on the hosts.
3. Build an lightweight Ansible docker image: docker build -t ansible .
4. Run provisioning tasks with command docker run --rm --network=host -it -v $(pwd)/log:/log ansible install-site.yml -e '{"username":<username>,"userpass":<password>}'

Rollback:

1. Run purge tasks with command docker run --rm --network=host -it -v $(pwd)/log:/log ansible purge-site.yml -e '{"username":<username>,"userpass":<password>}'

Notes:

1. You can specify modified hosts file without rebuilding docker image by adding mount with -v $(pwd)/hosts:/ansible/hosts to docker run command.
2. You can also specify another web app by editing roles/apache/tasks/install.yml. The app repo defined with the string: git: repo=<some repo URL> dest=/var/www/awesome-app
