Container fails to start when running on Mac - bind failed: Operation not permitted #38

Open antmerlino opened 2 years ago

antmerlino commented 2 years ago

Behaviour

I am trying to run this container on Mac and the container immediately exits. Enabling a higher log level, I get the following:

added interface eth0 ip=172.17.0.2 bcast=172.17.255.255 netmask=255.255.0.0
smbd version 4.15.5 started.

Steps to reproduce this issue

 docker run -p 445:445 -v "$(pwd)/data:/data" -e SAMBA_LOG_LEVEL=3 --name samba-test crazymax/samba

config.yml

    gid: 1000
    password: bar
  - user: baz
    group: xxx
    uid: 1100
    gid: 1200
    password_file: /run/secrets/baz_password

global:
  - "force user = foo"
  - "force group = foo"

Expected behaviour

Container should run and be able to bind.

Actual behaviour

Container immediately exits

Do you have the same issue with this cap?:

$ docker run --cap-add=sys_nice -p 445:445 -v "$(pwd)/data:/data" -e SAMBA_LOG_LEVEL=3 --name samba-test crazymax/samba
antmerlino commented 2 years ago

@crazy-max Yes same issue. No differences.

I'm not able to repro on an M1 mac mini (macOS Monterey 12.3.1) with Docker Desktop 4.10.1:

Not sure what the issue is

antmerlino commented 2 years ago

The only thing I notice is that you are running Monterey 12.3.1 and I'm running 12.5. Perhaps they updated something security-wise that's having an effect?

ludelafo commented 1 year ago

I'm having the same issue on my MacBook Pro (Intel) running macOS Ventura 13.1 (22C65).

I'm ready to help debugging this issue if needed.

ludelafo commented 1 year ago

I'm able to start the container without any apparent issues with the following command:

$ docker run -p 445:445 -v "$(pwd)/data/config.yml:/data/config.yml" -e SAMBA_LOG_LEVEL=3 --name samba-test crazymax/samba

The only difference is the direct mapping of the configuration file instead of the entire data directory. Could it be permissions related?

Edit

A working example is available here: https://gitlab.com/coloc-malakof/coloc-malakof/-/tree/main/samba

I've been able to keep the cache directory as a Docker volume as the lib directory inside /data seems to cause the issue.

Thanks for that, super helpful!
