– Hey, why is the shell prompt on the production server red now?
– Earlier: me@prod:~$ docker container remove --force the-application
Protip: If you’re used to shutting down your computer via the CLI, make it a habit to use an alias like off

This way you will never, ever turn off a remote server by accidentally using throwing poweroff
at a residual SSH connection.
the fact that you can shell in from your local environment is more concerning than the fact that you killed prod.
hope you aren’t supposed to hold any compliance requirements!
funny story though, you’ll use this when you’re mentoring later and some dumbass noob will still do it.
Here we simply have a tool that on dangerous commands like power off or reboot asks for the host name of the machine in question. Didn’t stop me from accidentally rebooting a machine once, but no matter
sounds interesting. do you have the name of the tool or is it a custom script
