That's a great question! Since Docker Hub is a massive library, there are images for almost every type of software you can imagine.
Commonly used Docker images are usually "Official Images" that serve as building blocks for developers. Here are some of the most popular ones:
-
Operating Systems (Lightweight versions):
alpine: An incredibly tiny Linux distribution (only about 5MB!).ubuntu: A very popular choice for a full Linux environment.
-
Web Servers:
nginx: Used for serving websites and acting as a proxy.httpd: The classic Apache web server.
-
Databases:
mysqlorpostgres: For storing relational data.redis: A fast, in-memory data store.mongodb: A popular NoSQL database.
-
Programming Languages/Runtimes:
python: Pre-configured with Python and pip.node: Everything you need to run JavaScript/Node.js apps.openjdk: For running Java applications.
-
Tools:
hello-world: A tiny image used just to test if Docker is working correctly (you'll likely use this in the next step!).
In the next part of this lab, you'll learn how to "pull" these images from Docker Hub to your own environment. Click Continue when you're ready
