Couple different packages not installing properly

Docker Desktop for Mac

Expected behavior

A build using an image form a Dockerfile derived form the official drupal image on hub.docker.com. I have added in drush and SSH installations. The output of the build indicates that everything went as expected. ie SSH was installed, drush was installed…

Actual behavior

When I run the buid and interactivly connect (docker exec -it live-web bash) and inspect the box, the /usr/local/bin/drush file is not there nor is ssh installed or the ssh_config files (since ssh never installed the /etc/ssh directory.) The same is true of just about everything else I install (composer, etc…) but those are commented out in the Dockerfile.

Worth noting I can install drush by hand by running the same commands directly on the interactive shell in the web container.
