[Help]: exec /entrypoint.sh: no such file or directory

[andrzej-dunowski]

Controller Version

v5

Describe Your Issue or Question

I recently launched the Omada Controller in a container on a Synology NAS DS925+.
It worked for a few days. I saw that an image update was available, so I updated it.
The container no longer starts. I get the error "exec /entrypoint.sh: no such file or directory" in the log.
I tried using earlier versions, but it didn't help. I have no idea what I did wrong.

Expected Behavior

Just run

Steps to Reproduce

Run it

So are you building the image from the cloned repo or pulling from Docker Hub? I am running the latest image just fine. Could you do a docker compose pull and then try to run the container again?

[andrzej-dunowski]

The image is downloaded from Docker hub

# docker compose pull
[+] Pulling 1/1
 ✔ omada-controller Pulled

# docker compose up -d
[+] Running 1/1
 ✔ Container omada-controller  Started

# docker compose logs
omada-controller  | exec /entrypoint.sh: no such file or directory

Are you directly deploying it with compose or are you using Portainer or Synology Container Manager directly? I've seen other issues where the entrypoint or CMD have weird configurations or they're misinterpreting them.

You can always to just try a very simple docker run as docker run -it --rm mbentley/omada-controller:5 to see if it starts without an persistent data, no ports mapped, etc just to make sure it does indeed run on your system.

I'm deploying it via Synology Container Manager.
At your request, I ran it from the terminal.

I ran it in a different directory so it wouldn't be linked to this project.

# docker run -it --rm mbentley/omada-controller:5
exec /entrypoint.sh: no such file or directory
failed to resize tty, using default size

Very strange. I do not know right offhand what's happening but you're running the exact same image as I am. I am curious about a few additional things:

1. Can you show me the output of this: docker run --rm --entrypoint /bin/sh mbentley/omada-controller:5 -c "ls -la /entrypoint.sh" as I want to see what is in the container.
2. Output of docker version
3. Output of docker info

Something tells me it's something weird with the docker version and/or something related to btrfs but I have nothing to really go off of on that - just a guess on where the problem may most likely be.

Yeah, there is absolutely something weird about your setup as this all works fine here:

docker run --rm --entrypoint /bin/sh mbentley/omada-controller:5 -c "ls -la /entrypoint.sh"
-rwxr-xr-x 1 root root 22816 Oct 13 20:13 /entrypoint.sh

The docker info says that your docker daemon is containerized which is odd - are you doing anything strange like running vDSM? The version of Docker they ship is old too but I do not know if that has anything to do with it.

With it saying your docker daemon is containerized, I do not know if there are any issues with using btrfs in a docker in docker situation - I've never tried it.

[andrzej-dunowski]

You pointed me to the possibility that Container Manager might be malfunctioning. I removed the package, along with the images and containers, and reinstalled it, and it works. I don't know what happened.
Thank you so much for your help!
