See #49

It could also be that it's an issue with the networking layer in docker.

On my WD-MyCloud EX 2 Ultra the Release MyCloudEX2Ultra_docker_19.03.8.bin doesnt work.
Port 9000 = connection refused.
I looked in the File /mnt/HD/HD_a2/Nas_Prog/docker/daemon.sh
Line 211 is ${DOCKERD} -D >> /var/lib/docker/docker.log 2>&1 & and not ${DOCKERD} -D --ip-masq=true >> /var/lib/docker/docker.log 2>&1 & like in the Source.
I changed it and restartet the Nas, but it doesnt work...

Its only working, if i bind the container to the Host Network with the Command "docker run -d --network="host" ..." like https://community.wd.com/t/package-docker-v18-03-1-ce-for-wd-my-cloud/222305/71

Has somebody any Ideas?

Just a note. After I upgraded to OS5 portainer started to work, but I didn't install the now separate Twonky app, but I do have Plex Server installed and the DNLA service on the Plex Server is enabled.

I installed 19.03.08 via the bin file then replaced the docker contents with 20.10.7 and ran a modified version of update_portainer.sh with a different port. When I tried to start the portainer container I get the following error:
Error response from daemon: runtime "io.containerd.runc.v2" binary not installed "containerd-shim-runc-v2": file does not exist: unknown

If the contents of the directory in the first snippet does not match the file names above it will cause an issue and then if the symbolic links in the second snippet are not created in /sbin, this will also cause an issue. These should be created by the start scripts for docker though.

Thank you @JediNite (very appropriate name if I do say so myself.) It would appear I ran into an IDT10 error when replacing the files yesterday and had missed containerd-shim-runc-v2. I also misunderstood how to setup the port forwarding to the container which fixed the connection issue.

Still unable to get Docker running due to port 9000 use by Twonky. Followed #49 and #58 to know avail.

@scuba-fan,

You have not given any more details on what the issue is you are seeing here exactly. Couple possible ways to resolve :
1.) Disable the use of Twonky Server and use something different for media streaming.
2.) Change portainer to use a different port. You can edit the "update_portainer.sh" script so that portainer runs on a different port (eg. change "9000:9000" to "9001:9000" within the script). This would then remap a different port on the NAS to the portainer container port 9000.

Cheers,
