Quick overview & setup. If you want to define several containers and also get them up and running, docker-compose is an efficient tool. First, you need to kick things off with a config file (docker-compose.yml) that encompasses images for both Nginx and certbot. You start by drawing a rectangle around the foreground image. Algorithm then segments the image. There can be some misclassifications. There you provide some nice touchups specifying this area is background, this area is foreground etc. Again segment the image to get very nice results.
