You have talked your development team and relevant people into using containers, and everything is going great. Now you need to deploy your app, but how do you do it? How do you manage multiple environments like Staging and Production? How do you get your container images where they need to go? Do you need a full stack of orchestration like Mesos or Kubernetes? Each application and deployment situation is different, but one tool can help small and medium-sized applications manage all these containers floating around. Follow along as we look at Rancher, a free and open source management software for your containers, which will provide you not only with server and container management, but deployment options as well.
