Hi I am unable to create a container due to the error

I have installed Docker and Portainer , however the config.yml file is on my Mac whereas the host for the docker container i Proxmox on a headless mini pc . How can i get the config file to from the MAC to the Container?

Any advice would be appreciated as i am a newbie to docker. Thanks in advance

The error message indicates that you mapped a directory into the container path /config/config.yml. Either you need to map a host file into a container file (I am not even sure if this is possible on Docker for Desktop) or even better map a host directory into a container directory.

Hi I realised and understood the error i have now changed them around and now i have a different error
Error parsing config: [Errno 2] No such file or directory: ‘/config/config.yml’ ??? I have created a config file thru nano in the container , however i am unsure how to mount it. If I create a directory for the file i will receive the error again as it is a directory ??

So confusing.

Don’t you think it’s time to share details about how you create the container?

I created the docker container in Proxmox lxc. Ubuntu 21.04 privileged and Nesting 1, with portainer. I run the docker-compose and config.yml

As a newbie i hope that this help and i look forward to your comments.

The error message indicates that /mnt/data/frigate/config.yml is a folder and not a file. Even though your container side of the volume mount looks like a file, docker mounts host folders into container folders - in your case a folder that happens to have a name that looks like a file name. Nginx on the other hand expects a file, not a folder. If you want a bind-mount volume to map a file from the host to the container, you have to specify a file on the host side of the mapping - apparently this is what you want to do, but don’t do.

Since /mnt/date/frigate seems to be a mountpoint that mounts a remote share, you will always end up with trouble. As mount propagation will be an issue: what the mounted remote share becomes available/unavailable/stale while the container is running?

You will either want to copy the config file to the docker host - or build your own image, where you copy the config file into the image and make it a fixed part of the resulting image.
