logs folder permission

[ove...@gmail.com]

Hello everyone. Everytime I create a new containers on Kubernetes, new log folders in /var/lib/docker/containers get created. The permission is automatically set to drwx------ . That doesn't allow me to correctly collect the content and read it through FluentD. Any suggestion on how to fix the situation?
Thank you so much in advance.

It happens also if you run the docker image on your local PC, right?

Probably you need to create it and chmod in your dockerfile, but remember that docker storage is not persistent and it gets erased every time the container is removed (on deploy, container crash, node drain, etc.)

`/var/lib/docker/` is managed by docker and it is not intended to be consumed outside of docker directly. IIUC, `docker logs` is the interface that users are expected to use. Is running "fluentd" as root user an option?

Unfortunately FluentD runs with a user called FluentD

I think there must be a way to do what I am trying to do.

I don't think I can do that. Isn't Dockerfile just handling docker configuration? I don't have access to folders on the guest machine.

Oh, I see what you mean now. 

I don't know how to tell docker the ownership, maybe you can set a umask? Maybe there are flags too, don't know much about docker.
