[feature request] plugin to work with Docker containers filesystems

[unxed]

Currently Docker suggests using docker cp <src-path> <container>:<dest-path> to copy files to/from container. Not very friendly way if you need to copy large number of files from/to different folders.

It would be nice to have far2l plugin allowing to work with docker containers filesystems just like netrock allows to work with remote filesystems.

May be even as NetRocks protocol handler that would simplify implementation

Please note that container FS is available within the host FS tree if you know the PID of the main process of the container.
For example, this is how you can get to it in bash:

❯ docker inspect -f '{{ .State.Pid }}' 11e4ad105ecc
2932
❯ sudo -i
[sudo] password for user: 
❯ cd /proc/2932/root
❯ ll
total 48K
lrwxrwxrwx   1 root root    7 Nov  1 23:15 bin -> usr/bin
drwxr-xr-x   2 root root 4.0K Apr 18  2022 boot
drwxr-xr-x   5 root root  360 Feb 14 11:31 dev
...skipped...
drwxr-xr-x  14 root root 4.0K Nov  1 23:15 usr
drwxr-xr-x  11 root root 4.0K Nov  1 23:18 var

Or you can launch far2l within the correct directory with the following one-liner:

sudo far2l -cd "/proc/$(docker inspect -f '{{ .State.Pid }}' 11e4ad105ecc)/root"

I think it means that you don't need protocol handler, because all FS operations already work.
Far2l just needs some fix for using the same instance for entering this /proc/<pid>/root directory.

is available within the host FS tree

Is it read-only access or writing is also enabled?

Yes, both read and write access is supported.

try next python plugin :) udocker, some methods are still missing: mkdir, rm, rmdir
