Docker applications

A lot of applications are provided in the form of Docker images that can be downloaded from the internet. If we knew the image name, then it would be enough to run it in the same way we did with the hello world example. How can we find the desired application image on the Docker Hub?

Let's take MongoDB as an example. If we like to find it on the Docker Hub, we have two options:

• Search on the Docker Hub Explore page (https://hub.docker.com/explore/)
• Use the docker search command

In the second case, we can perform the following operation:

$ docker search mongo
