Microservices are tough to learn. Not only do you have to learn deep and complicated tools. You must also learn to build a distributed application. This requires new design patterns, protocols and methods of communication. That’s a lot to learn!

Have you ever written a large body of code and then suffered a feeling of dread before testing it?

Larger bodies of code hide more bugs and are more difficult to test.

👇 While coding, bugs creep in and hide.

The longer we code without feedback, the more bugs we accumulate.

The process of troubleshooting and debugging our code is often time consuming.

The "docker run" command allows you to instantiate a container from an image. That means you can easily create an instance of an application, server or microservice.

Here's a quick visual guide:

#docker Here's the general format of the command:

Yesterday I posted some of the amazing graphics that @ManningBooks have done for my book Bootstrapping Microservices!

Today I show you some examples of how awesome the code listings are with annotations rendered in their final form...
