Searching for Images

In this step, you will search for essential Docker images in the repository and gain insights into their details.

1. Search for an Alpine Linux Docker image using the docker search command:

   docker search alpine

   Explanation: The docker search command allows you to explore available Docker images in the repository. The search term "alpine" in this example represents the image you are looking for.

2. Explore the details of the "hello-world" Docker image:

   docker search hello-world

   Explanation: This command helps you gain a deeper understanding of the "hello-world" Docker image.

   - name: Check Hello-World Image Search
     script: |
       #!/bin/bash
       if docker search hello-world | grep -q "hello-world"; then
         exit 0
       else
         exit 1
       fi
     error: "Hello-World image search failed."

Refining Search Results

In this step, you will refine your search by filtering the results to find the most suitable Docker images.

1. Refine the search for Docker images related to NGINX:

   docker search --filter is-official=true nginx

   Explanation: The --filter option allows you to refine your search based on specific criteria. In this case, you are filtering for official NGINX images.

Summary

In this lab, you have delved into the art of searching for Docker images in the repository. By mastering the docker search command and refining your search criteria, you have gained valuable insights into sourcing the most relevant Docker images for your specific needs. This knowledge will undoubtedly contribute to the wisdom of Atlantis and further empower its inhabitants in their technological pursuits.
