Digest and Test

Let’s refresh our memory by summarizing the main ideas discussed in this chapter:

• We learned how to dockerize a Django application. We started by looking into Docker and its use in the development of modern applications.

• We also learned how to build a Docker image and run a container using this image—this introduced us to some limitations of Dockerization using Dockerfiles.

• This led us to learn more about Docker Compose and how it can help us manage multiple containers with just one configuration file.

• This directed us to configure a database and an NGINX web server with Docker to launch the Postagram API.
