Sebastopol: O’Reilly Media, 2016. - 65c. Docker is one of the most exciting open source projects right now. By packaging the application in a container with all the other software it needs to run, Docker enables an application developed on a laptop to run in the same way on a production server.Being in production, however, introduces a whole host of challenges that you don’t always think about in development. Now you have to worry about connectivity, load balancing to scale and handle increased load, being secure against malicious users, and sharing resources with potentially hundreds of other apps (or microservices) running within the same environment. Having a good Docker networking and service discovery architecture in place is key to being successful with your Docker-based applications.In this report, author Michael Hausenblas addresses the challenges of networking and service discovery with Docker.Though not always top of mind in development, building a good networking and service discovery story early on will save you more than a few bad days when you’re in production.
