Learning Objectives

Search and pull images from Docker Hub

Understand image tags and versioning

Inspect image layers and metadata

Manage local images efficiently

Step 1

Docker Hub is the default registry for Docker images. Let's search for popular images.

docker search nginx

docker search --filter stars=1000 nginx

The `docker search` command queries Docker Hub for images. The filter option helps you find popular, well-maintained images with many stars.

You'll see a list of nginx-related images with columns for NAME, DESCRIPTION, STARS, OFFICIAL, and AUTOMATED.

1
Look for OFFICIAL images (marked [OK]) - they're maintained by Docker or the software vendor
2
High star count usually indicates a well-maintained, popular image
3
Check the image description for specific use cases
