Now you know a lot about Docker stacks. You can easily create application definitions with a compose file and then deploy those applications using the stack deploy command. You can explore the details of your deployed stacks with the ls, ps, and services commands. You can scale your applications with easy modifications to your compose file and by executing the same command used to deploy your app. Finally, you can remove an application that has reached the end of its life with the stack rm command. With great power comes great responsibility, so be very careful with that remove command. You have enough information to create and orchestrate world-class enterprise-grade applications now, so get busy! However, if you would like to learn how to use Docker with Jenkins, you'll be pleased to know that that's the topic of Chapter 8, Docker and Jenkins, so turn the page and start reading!
