Preparing Docker Apps for Production from Pluralsight

It's easy to run your apps in containers, but "docker run" isn't going to get you very far in production. This course will teach you all the best practices for packaging and running your apps with Docker, Docker Compose and Kubernetes.

Containers need to work with the features of the platform they're using if you're going to get the most out of them. In this course, Preparing Docker Apps for Production, you’ll learn all the best practices for setting up and running containerized applications.

First, you’ll see how to separate app configuration from the container image, so you can configure apps independently. Next, you’ll see how to push application logs out from containers and collect them in a centralized store. Then you'll take advantage of self-healing features by adding health checks and dependency checks to your containers. Finally, you’ll learn how to manage network traffic so you can route incoming requests to the right containers.

When you’re finished with this course, you’ll have understanding of how containers work in production, so you can plan your path to go live with Docker.
