Nigel Poulton of Technical Deep Dive comments:
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!
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:[email protected]:/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! And yes, I know it’s been throwing “Warning: ‘–tree’ is deprecated” warnings at me since forever. I just never thought they’d actually go through with it.
And you know what right… I know it’s just a piece of software we’re talking about here.. but I’m seriously mortified by this. I don’t think I’ve ever had a more poignant lesson that it’s the litle things that make a big difference. Such a tiny command, that was so insanely powerful for Docker image management.
Great workaround for a missing command from Nigel.
