Output in terminal

[hot22shot]

Hello,

I'm running code-server in a docker container and I have an issue regarding an application I use (node.js based).

When executing the command from a terminal in code-server :
$./myapplication --version
return nothing (I tried to redirect the output to a file to check it wasn't just not displayed).

If I log in the container directly from my server (through docker exec -it mycontainer /bin/bash) and try the same command :
$./mybinaryfile --version
It works (same user, same shell).

I tried with sh/bash and there's nothing in the logs of code-server.

I suppose it is coming from my application but of course I won't get any support from the vendor as code-server is not a supported environment blablabla.

Any leads on what or where I could/should look into ?

Regards

Maybe code-server's terminal is using sh and somehow that's affecting things? Could try running bash first and then the --version command.

Other than that I'm not sure what could cause the difference. If that doesn't solve it could you post a Dockerfile that replicates it?

I tried with sh and bash within code-server with the same result.
That being said I also made some tests with strace, I narrowed down the problem to a perm issue as it works with sudo.
I suppose sudo gives my user within code-server more permissions to execute my application.

For the time being I've set the setuid bit so that my app executes with root permissions.

My host is a DS-916+ from Synology, and here's my docker-compose file :

version: "2"
services:
    vscode:
        container_name: vscode
        network_mode: bridge
        environment:
            - TZ=Europe/Paris
            - "HASHED_PASSWORD=zapped"
        volumes:
            - '/volume1/docker/vscode/.config/:/home/coder/.config:rw'
            - '/volume1/docker/vscode/.local:/home/coder/.local/share/code-server:rw'
        ports:
            - 8443:8080
        restart: unless-stopped
        image: codercom/code-server:latest

And the application I'm trying to use is that one :

@hot22shot Can you try running docker-compose again with these two environment variables. I think assigning these two environment variables shall fix the perm error.

-e "DOCKER_USER=host-username"  
-e "USER=host-username"

Please report back if this solved your issue, otherwise I may dig deeper into your problem.

Have a great day ahead!

Still the same issue, I assumed host-username should be replaced with my user ?

I checked the userid of the user coder inside the container, it is still mapped to 1000, my host username is 1026.
How does these environments variables should work ?

edit :

I forced my UID/GID by adding user : "1026:100" to docker-compose which are my respective userid and groupid on my docker host, but still no change :(
