Orchestration: Jenkins, Docker
Automation tools: Ansible, bash
CI description:
by hook:
- build docker image
scheduled:
- backup runned application once a day
checks:
- deployment after installation/update
- check if application is accessible every 15 minutes
After Dockerfile is pushed to pipeline repo in image/<version> branch, Docker Hub builds this docker image.
In Jenkins parametrized pipeline we select the version to deploy. It polling image and running it as pod via docker-compose.
Ansible implements Nginx's reverse proxy for the application.
The pipeline is same for new and upgrade deployments, but for new deployment we should check the "InitialDeployment" boolean parameter which is skipping backup proccess before the deployment starts.
Before the deployment proccess is started (the only exception is "InitialDeployment" boolean is checked) we start job "Backup" which backups database and application content (directory wp-content) and stores it as Jenkins' artifacts.
The last step of deployment pipeline is to check every one second until timeout if the application is accessible after the deployment proccess is done. If it fails we suppose that entire deployment proccess is failed. In this case previous version of application is deployed and the database and the application content is restored (just for case).
Backup and restore processes also can be runned manually.
