Tomcat server sample app hosting

A very basic structure for hosting sample application on tomcat application server.

Prerequisities

1. Docker is installed on the machine
2. Ansible is installed on the machine
3. Python/Pytest is installed on the machine on default location /usr/local/bin/pytest
4. Port 8080 is available

Steps

• Clone git repo to your local repository
• Run ansible playbook with predefined hosts file : sudo ansible-playbook -i hosts main.yml
• All done - application should be hosted on http://localhost:8080/sample

Description

• Folder /docker contains Dockerfile and sample app (sample.war).
• File hosts contains localhost address - our app destination.
• File main.yml is playbook containing complete server deployment procedure.
• File test-avialability.py checks if our app is up and running at desired address.

Main.yml structure

• Ansible first checks via pytest if our app is currently up and running, and if yes, skip whole process.
• If our application is not running at http://localhost:8080/sample, first docker image is build, then run at localhost:8080.
• After that pytest check runs again to make sure that app is up and running.
