Port view on zima

Insight & Feedback
1

i was wondering if there is a way to see all the ports used and by what application

2

If you open terminal and sign in, or via ssh you can run this and get a list of docker assignments

sudo docker ps -a --format "table {{.Names}}\t{{.Image}}\t{{.Ports}}"

It will get you names with image name and then ports.
This will get a list with each assigned port group on a new line , separated for easy import to excel.


	 sudo docker ps -a --format '{{.Names}},{{.Image}},{{.Ports}}' \
| while IFS=    echo "$ports" | tr ',' '\n' | sed 's/^ *//;s/ *$//' | while read port; do
        [ -n "$port" ] && echo "$name,$image,$port"
    done
done >  /DATA/Documents/PortUsage.txt, read -r name image ports

It would be very cool if something along these lines could be built into ZimaOS Maybe a GUI list of Docker App to Port list.
I’m sure it could be refined, but it’s what I came up with quickly.

thank you. do you know of a way to release for like 80 and 443 cause they some how got stuck to a previous install of nginx

4

Port 80 and 443, 80 for sure is tied to the Zima OS UI, I would assume 443 is. If it is also tied to another nginx I don’t know.

you are right id love to see a list in the settings menue

Have a look at Dockpeek in the ZimaOS App Store, it gives a full overview of all Docker containers and clearly shows which ports are in use and which app is using them.

So, I just installed dockpeek, and it has nothing showing up.

Dockpeek works because /var/run/docker.sock is mounted and DOCKER_HOST=unix:///var/run/docker.sock is set.
If someone sees an empty list, they should compare their settings to this screenshot.

Thank you for that!

By default we have been trained to change the volume on the ZimaOS side to the standard
/DATA/AppData/AppName See How to understand Docker App's paths On ZimaOS | Zimaspace Docs

So, when I install stuff from the IceWhale store I tend to trust the paths. But I’ve learned from all the 3rd party stores, to change the shared volume. Since this is a BigBear app not an IceWhale app by default I changed that. I just uninstalled and reinstalled it and didn’t touch that this time and now it works.

I didn’t even compute that .sock part
So yeah I missed that. This is one that the only thing you need to touch is username/password/secret key

I don’t have any idea what the secret key is used for.

No worries at all, easy mistake to make.

Dockpeek is a bit different because it must keep the /var/run/docker.sock mapping intact. Changing it to /DATA/AppData/... breaks its access to Docker, which is why nothing shows up.

For this app, you’re right:

  • Leave the volume mappings exactly as installed
  • Only adjust username / password / secret key
  • Reinstalling without touching the volumes is the quickest fix

The secret key is just used by Dockpeek for its own internal auth/session handling. If you’re not exposing it publicly, the default value is fine.
