Steps

  1. Pull the latest container (image ID ab59549aae7c) from DockerHub:

     $ docker pull mozilla/ssh_scan
 Using default tag: latest
 latest: Pulling from mozilla/ssh_scan
 Digest: sha256:5a039264d6786d1c0841252d2990e82bced5339d1e8f23b3cb04ec1fb7655b77
 Status: Image is up to date for mozilla/ssh_scan:latest
 docker.io/mozilla/ssh_scan:latest

  2. Run the example command from the README file:

     $ docker run -it mozilla/ssh_scan /app/bin/ssh_scan -t sshscan.rubidus.com
 Traceback (most recent call last):
        2: from /app/bin/ssh_scan:7:in `<main>'
 	1: from /usr/local/lib/ruby/2.7.0/rubygems/core_ext/kernel_require.rb:92:in `require'
 /usr/local/lib/ruby/2.7.0/rubygems/core_ext/kernel_require.rb:92:in `require': cannot load such file -- netaddr (LoadError)

Expected results
SSH scan runs and returns JSON output.

Actual results
See traceback above.

Technical
I was able to get ssh_scan to work by entering the container via a shell, then manually running gem install for each of its dependencies. I suspect something about the gem installation process is broken for the container build.
