First up…. this has nothing to do with saving trees – at least of the botanical variety. This has everything to do with Docker in the enterprise!

Background

So… I spun up some new Docker hosts the other day… and it wasn’t long before I needed my trusty old friend `docker images –tree`. Well what was my horror when I got bitch-slapped with this:

npoulton@ip-10-0-0-90:/home/ubuntu$ sudo docker images –tree flag provided but not defined: –tree See ‘docker images –help’.

Basically the `–tree` flag’s been pulled from the code!…
