1. Push code to GitHub

2. Jenkins job triggers

3. Code testing ( we can use Teamcity )

4. If all tests pass then Jenkins job builds the Docker image and pushes it to our Docker Hub

5. On our server we run periodic checks with cronjobs, ECR ( Elastic Container Registry ) where there we keep another copy of the update Docker image for failove scenarios explained earlier on Application Pipeline.
