Generally, I think you should build docker images and perform testing and linting against those using the functionality of the pipeline of your favorite git service. You can then trigger deployments with services that leverage docker images, and you feed it the same build images you were testing for deployments. Different applications have different deployment details, but whatever the application, if you can dockerize it then you can generally roll it out with little to no downtime, and it’s usually fairly portable to other services at that point too.
