Show Containers in a Clean Triage Table
You need a fast view of container state, image, uptime, and published ports without wrapped columns hiding the important parts.
Command
docker ps -a --format 'table {{.Names}}\t{{.Status}}\t{{.Image}}\t{{.Ports}}'What changed
Nothing changes. Docker prints container metadata in a narrower table.
Danger
safe
When to use it
Use during first-response container triage to see what is running, stopped, restarting, or exposing ports.
When not to use it
Do not treat it as an application health check; it reports Docker state, not whether the app works.
Undo or recovery
No undo needed because this command is read-only.
Expected output
A table with container names, statuses, images, and port mappings.

YouTube Short
Readable docker ps.
When Docker output wraps into a mess, format it. Names, status, image, and ports are the first fields you need.
LinkedIn hook
Turn noisy docker ps output into the few fields operators scan first.
Question: What fields do you always want in your first Docker triage view?

A: Turn noisy docker ps output into a clean table.
B: Your first Docker triage command should be readable.
