Summary

In this chapter, we have introduced Docker Swarm, which, next to Kubernetes, is the second most popular orchestrator for containers. We have looked into the architecture of a swarm, discussed all the types of resources running in a swarm, such as services, tasks, and more, and we have created services in the swarm and deployed an application that consists of multiple related services.

In the next chapter, we are going to explore how to deploy services or applications onto a Docker Swarm with zero downtime and automatic rollback capabilities. We are also going to introduce secrets as a means to protect sensitive information.

Beginning DevOps with Docker

Beginning DevOps with Docker

Making sure that your application runs across different systems as intended is quickly becoming a standard development requirement. With Docker, you can ensure that what you build will behave the way you expect it to, regardless of where it's deployed. By guiding you through Docker from start to finish (from installation, to the Docker Registry, all the way through to working with Docker Swarms), we'll equip you with the skills you need to migrate your workflow to Docker with complete confidence.
