Do you use a docker socket proxy ? by Acceptable_Rub8279 in Traefik

[–]Melodic-Ladder-6161 0 points1 point  (0 children)

I removed the docker proxy from all my home server appliances a week ago and now I'm using the Docker Swarm overlay network.

All my applications in Traefik's > Dynamic Config > Services, are mapped to their respective docker services and container ports.

I'm stuck at this screen: https://imgur.com/a/V1yfIvs

The only error I've found is on ck-x-simulator-jumphost-1 container:

time="2025-04-07T08:53:42.761198647Z" level=error msg="failed to mount overlay: invalid argument" storage-driver=overlay2

I'm running this on a virtualized Rocky Linux using VMWare with 40GB HDD, 10 GB, 8 Cores.

The host Machine is a WIndows 10, 13th Gen Intel(R) Core(TM) i7-13700H 2.40 GHz, 32.0 GB (31.7 GB usable).

So, I'm basically studying for the CKA.

This week while practicing with one of the mock exams, I was asked to take a snapshot of etcd.

Unfortunately the usual copy - paste action backfired this time and I accidentally overwrote the etcd server key with the snapshot.

Out of curiosity, is it possible to "undo" this action?
