Podman

Hi everyone! I want to be able to access a (fuse-type) cloud drive mounted inside a container as the binary is proprietary and I do not want to mount it on the host for security and privacy purposes. I have tried to quickly spin a podman container and bind the folder that corresponds with the drive with the rshared flag but the folder appears to be empty on the host while inside the container it works just fine.

I am running the following commands:

$ podman unshare mount --make-shared --bind /clouddrive /clouddrive
$ podman run -i -t --cap-add=sys_admin --network host \
	--security-opt label=type:container_runtime_t \
	-v /cloudbinary:/bin/cloudbinary:ro \
	-v /clouddrive:/clouddrive:shared \
	--device /dev/fuse:/dev/fuse \
	-v /bin:/bin:ro \
	-v /lib64:/lib64:ro \
	--privileged --name=name image /bin/bash

Inside the rootless container I run:

# cloudbinary login username
<enter password>
<successful login>
# ls /clouddrive
file1 file2 file3

But on the host /clouddrive is empty:

$ ls /clouddrive
<nothing>

Running findmnt -o TARGET,PROPAGATION /clouddrive inside the container yields:

TARGET      PROPAGATION
/clouddrive shared,slave

Running findmnt -o TARGET,PROPAGATION /clouddrive on the host yields:

TARGET      PROPAGATION
/clouddrive shared,slave

I have almost no prior experience with podman but I read something about how a rootless container might not work because the user and group owning the folder is not the right one. Does anybody have an idea on how to fix this? Thank you.

Update: It seems the cloud binary is unmounting any drive with the same name at startup and mounting it's own drive. Would that be a problem? Running findmnt still shows shared but the slave label has disappeared after the binary mounts it's own drive. Is there anyway to "reshare" it at runtime/dynamically?

Hello,

I have two Podman containers. One container that contains Linkstack and another container for the Nginx Proxy Manager. Now I want the Nginx Proxy Manager to retrieve the website from the Linkstack container. Unfortunately this does not work.

I integrate the two containers in a network. I realize this with podman-compose.

First, I created the network with "podman network create n_webservice".

Compose.yaml

services: NGINXPM: networks: - n_webservice container_name: NGINXPM volumes: - /home/fan/pod_volume/npm/data/:/data/ - /home/fan/pod_volume/npm/letsencrypt/:/etc/letsencrypt ports: - 8080:80 - 4433:443 - 9446:81 image: docker.io/jc21/nginx-proxy-manager:latest linkstack: networks: - n_webservice container_name: linkstack ports: - 4430:80 image: docker.io/linkstackorg/linkstack networks: n_webservice: external: n_webservice

I have tried everything possible in the Nginx Proxy Manager with the entry, but unfortunately I can't get any further. The destinations http://linkstack:4430 and http://127.0.0.1:4430 are not working.

Can someone please help me how I can access the linkstack container from the NGINXPM container?
