Solved docker gui doesn't show any info

[spar09]

I am running a 418play with an extra RAM module for a total of 8GB of RAM. I have been running docker applications for the last 6 or so months without much problem. As of today the docker gui on the DSM has stopped displaying any details of the containers running on the system. I tried a reboot but that did not help.

Some of the containers auto-started(as I had set them up to, I think) after the reboot and are working as expected. But I cannot configure or control any other containers due to lack of the output on the gui.

I also tried to run docker ps through ssh but the command doesn't complete. I have to ctrl-c to get back to the prompt.

Any suggestions would be appreciated. Thanks.

what is answer for SSH:
synoservice --is-enabled pkgctl-Docker

# synoservice --is-enabled pkgctl-Docker pkgctl-Docker is enabled.

did you tried to upgrade the Docker package?
Similar symptoms for me in April, when upgrade process hung in Synology package centre.

No, I did not do anything. I was away for the day and once I came back some containers weren't behaving as expected. So started investigating and noticed the GUI was not showing anything.

synopkg stop Docker
synopkg status Docker
then restart NAS
then: synopkg start Docker

That worked.

I am curious though about how the steps you suggested differ from what happened when I tried a shutdown - start cycle earlier. I would think that all services are stopped on shutdown and started on boot. Is that not the case ?

you welcome,
it was just my “analytical” approach
i thing it wasn’t problem of Docker pkg, but Syno GUI

Alright, thanks a lot for your help.
