  2. You can confirm it is there with:

    docker images
Pull the latest `httpd` image.
  1. Pull the latest httpd image:

    docker pull httpd:latest

    Note: If you don’t put the version, the latest version is assumed.

Pull nginx 1.15.
  1. Pull nginx version 1.15:

    docker pull nginx:1.15
  2. To confirm that it is there:

    docker images
Compare the history.
  1. Look at the history for both the httpd and nginx images.

    docker history httpd
