Documentation: Document the needed access rights to apply to the mounted home folder for a user

[OhmegaStar]

Hi,

I've created a ftp server, mounted a folder in my docker host as the /home/ftpusers directory

I ran the
a folder has been created there for the user by this command (a .sh script):
pure-pw useradd $1 -f /etc/pure-ftpd/passwd/pureftpd.passwd -m -u ftpuser -d /home/ftpusers/$1

the directory was created. The user cannot upload any files to the home folder (access denied).. i guess theres something wrong with the access the the folder (is created by root):
drwxr-xr-x 2 root root 4096 Mar 30 14:07 testuser

???????

Hope for some help

Hi @OhmegaStar ,
Sorry for my delayed reply, have you found any answers around this?

I've not run into any user permission issues yet myself, but it might be an issue outside this docker image. Is this of any use to you? https://denibertovic.com/posts/handling-permissions-with-docker-volumes/

Hi @stilliard
thanks for answering & asking.

Yes, it seems it's an issue with setting the UID/GID of the ftp user so it matches a UID/GID on the host servicing the docker image / the mounted folder.

It would be nice if the UID/GID of the ftpuser could be configured as an env var to the image / or alternatively to:
pure-pw useradd $1 -f /etc/pure-ftpd/passwd/pureftpd.passwd -m -u ftpuser -d /home/ftpusers/$1
oh - and it seems you can:
pure-pw useradd test-user -u 1234 -g 1234 -d /path/to/my/dir

then maybe a documentation update is all that is needed ??

Ah sure that makes sense.
I'll update the docs for this shortly thank you!

Hello guys,
How do I find out the -u and -g parameter to use in this scenario?

Thanks

[OhmegaStar]

@marcoskichel you would have to look at the docker host that has the folder that is mounted into the docker image, that folder will have user & group access information, that can then be translated into the numerical values you need. the translation probably depends some on the *nix flavor you run on the host server.

/# pure-pw useradd www -f /etc/pure-ftpd/passwd/pureftpd.passwd -m -u root -g root -d /home/ftpusers/www
You must give (non-root) uid and gid
Unable to open the passwd file: No such file or directory

Same problem, I can't figure out it for now

Edit: Ok I got it, you have to specify the -u (for uid) and -g (for gid) number. Choose one that you want but not the 0 which is for the root. I hope that will fix your issue @fjarcticfox

What if the host that has the folder is owned by root? like named volumes located in /var/lib/docker/volumes ?
