I have progress :

tried a few different layouts of that line in the Putty CLI and eventually got this to run the file.

sudo docker exec -u root nginx php /config/www/EXDdata/exdgo.php

seems like the '/config' already points to the first 'www' so only needed the second 'www'

Am testing in the OMV Scheduled Tasks now

Should the php file be run as root?

i have no idea ( subject unknown to me )

I did try changing 'root' to 'pi' and the message was simply 'error occurred' and the details show :

Oh sorry:

docker exec nginx sudo -u root php /config/www/www/EXDdata/exdgo.php

still results in an error :

Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; export SHELL=/bin/sh; sudo --shell --non-interactive --user=root -- docker exec nginx sudo -u root php /config/www/www/EXDdata/exdgo.php 2>&1' with exit code '126': OCI runtime exec failed: exec failed: container_linux.go:349: starting container process caused "exec: \"sudo\": executable file not found in $PATH": unknown

You could either add cron to the docker container via a container mod.

Or you could run it via schedule jobs in omv. With this method you need pass the command with docker exec. For example create a scheduled job as root: docker exec sudo -u abc php /config/www/myscript.php

set the Command in the OMV Scheduled Tasks :

docker exec sudo -u root php /config/www/www/EXDdata/exdgo.php

Got this error :

Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; export SHELL=/bin/sh; sudo --shell --non-interactive --user=root -- docker exec sudo -u root php /config/www/www/EXDdata/exdgo.php 2>&1' with exit code '1': Error: No such container: sudo

What's the correct way to run a recurring task ?

Previously on OMV 4 with the Nginx plugin, I simply added a OMV Scheduled Task with the 'command' pointing to the php file.

Now on OMV 5, Nginx is running in a Docker Container.

Do I use the same Scheduled Task method ?

How do I determine the correct path to add for the Command ?

solved

Simple solution was to add a line right before the ftp_put php code :

ftp_pasv($ftp_conn, TRUE);

Problem with linux php ftp nginx portainer docker openmediavault problem.

With some awesome assistance and guidance by Morlan, I have managed to get Nginx installed and can access the files.

Next problem is uploading files using php ftp_put from the Nginx based php scripts, to a remote ftp web server.

Was running OMV4 on RPi3B+ with Nginx as a plugin. Worked 100%.

Upgraded to RPi4 4Gb and OMV5.

OMV5 does not have plugin for Nginx, so has to be in a Container in Docker.

So Installed Docker, Portainer, and created a Stack in Portainer for Nginx.

In the stack script, I set the Volume to my existing Shared Folder, and I can map network drive to my PC and view & edit these files from my PC. All good so far.

Started testing php script, and had to make a few small path changes, then everything worked 100%, except for an ftp_put command.

The ftp connect and Login both work, but the ftp_put simply creates a zero sized file on the destination online ftp server, and after about a minute, then pc browser says : " 504 Gateway Time-out ".

Found an error log that contains :

2020/10/21 18:27:46 [error] 333#333: *1 upstream timed out (110: Operation timed out) while reading response header from upstream, client: 192.168.1.91, server: _, request: "GET /EXDdata/testupload.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "192.168.1.136"

I know this script worked perfectly when on the RPi3B+ on OMV4 with Nginx as a plugin, so I assume the problem is related to the new Pi, Docker, Portainer Container settings, or some config on Nginx.

Anyone able to diagnose this ?

something went wrong :

ran this as a stack :

---
version: "2.1"
services:
  nginx:
    image: linuxserver/nginx
    container_name: nginx
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Africa/Johannesburg
    volumes:
      - /svr/dev-disk-by-label-NAShd1/www:/config
    ports:
      - 80:80
      - 443:443
    restart: unless-stopped

seemed to install correctly, but ...

when I browse to the IP from my PC ( 192.168.1.136 ) then I get a page saying :

Welcome to our server

The website is currently being setup under this address.

but when I go to the shared www folder, it contains my original pages ( including the original index.html page ) and not this page that I am seeing.

There are no new files in the www shared folder

Quote from Morlan

I suggest to use the container by linuxserver https://hub.docker.com/r/linuxserver/nginx

The images are well documented. You need to bind your www folder to the http root in the container

Thanks for the advice.

would that be through Portainer ?
Is the Bind in the settings, or a command line instruction ?

Which Nginx container are you using?

I have since deleted it ( multiple times ) and removed the Volumes and Images

Quote from Morlan

Which Nginx container are you using?

it was listed under Portainer > App Templates > NGINX Container

I simply can't find anything that tells me how to use nginx after installing a Container in Docker.

Not even where to put the html / php files, how to access that folder, nothing.

Looks like it may be a better option to scrap OMV 5 and go back to OMV 4 and use nginx as a plugin

I can not get this to work, and know i must be missing something simple ( likely lack of understanding on my part )

Just upgraded Pi3 ( OMV 4 ) to Pi4 and installed OMV 5 ( technoDad video guides ).

Have Docker running, and Portainer installed.

Used 'Add Templates' to create a Container for nginx

I need ( want ) to use an existing Sharedfolder ( www/ ) that I have on the HDD that was used by nginx on the Pi3 and contains my html and php files.

How do I tell nginx to use that folder ?

I also want to be able to access that folder from my win PC, which I can do as the www/ folder is a shared folder and listed in SMB

after a load of digging with Cloud Commander, I found the default index.html page here :

/var/lib/docker/volumes/c045ac8ef091973de611ad602b647cbfdf8e8181d470b9ee2d13f26e60cb6a46/_data

Verified by editing the file, changing a character, and saving. When viewed from my PC browser, the change is visible.

So having found the location of the files, I tried adding the path as a Shared Folder in OMV5, and added to SMB so I can map as a network drive from my win PC.

The network map connects, but I can't see any of the 3 files that are in the folder on the Pi.

Is this a setting, or better solution - how do I specify the folder for nginx to use, as a different shared folder ?

I am completely lost.

Replacing Pi3B+ ( OMV4 ) with Pi4 ( OMV5 ), and found that I can't simply move the SD card from Pi3 to Pi4.

Followed TechnoDad videos to get a new image on to the SD and install OMV. OK to this point.

On the OMV4 / Pi3, I had nginx running as a plugin.

If I understand correctly now, with OMV5, these plugins ( which had system wide access ) should now be run in a self-containing bubble, Docker.

I guess Docker is the OS for these bubbles, and Portainer is the User Interface for the bubbles / dockers.

So using Portainer > App Templates, I found nginx and 'Deploy Container' ( I assume this is the equivalent of an install )

Next, went to Portainer > Containers and I see the "PiWeb' named container in the list.

I can browse ( on my PC on same network ) to the IP of the Pi4, and I get the " Welcome to nginx " screen.

On the Pi3, I had the web folder that nginx set as a shared folder, so that I can access it from my local PC as a network folder.

The nginx plugin listed the server root as : /dev-disk-by-label-NAShd1/www/

How / where do I change the settings in nginx / Portainer to use that same specific folder for the web pages ?

Quote from ryecoaaron

If you have everything up to date it should be fine. You might have to run omv-firstaid if the network adapter doesn't get an IP address.

Thanks. I use a mikrotik router so I think I can just delete the existing Static IP / MAC link, and create a new Static IP for the Pi based on the Pi's new MAC Address..

Hi

Running OMV 4.1.36 on a Pi 3B+

If I replace with a Pi4, can I simply move the microSD from the Pi3B+ to the Pi4, and expect everything to work ?

update - decided better to set up a web server on the Pi, and run this in php

Does this sound correct ?

Starting to set up a small web server on my Pi.

Installed Nginx, mySQL and php7

Testing using php to send mail ( code known to work on another online php server ) and found I need a mail server installed.

Dug around and found that Postfix is already installed - I guess that was added as part of OMV as I was able to send mails from OMV when that was the only thing running on the Pi.

Could not get php to send mails - nothing worked and ( completely clueless ) tried for hours to find a way to make it work.

Eventually I thought - maybe I should test the mail sending from OMV > System > Notifications just to check the Pi can actually send mail.

The 'General Settings' was disabled ( probably because I didn't understand the mails it was sending me anyway ).

As soon as I enabled it, a load of mails arrived on my PC from the php script. They must have been sitting in a queue somewhere.

So it appears that the 'enabled' setting in OMV, also controls the sending of mail from php scripts.

ok. I think this is working now

messing around with some google searches, and came across this :

First, remove the symlink you just created by running:

rm -rf /usr/share/nginx/www

That won’t delete phpMyAdmin, it’ll just delete the symlink. Now we’ll create a new one using:

sudo ln -s /usr/share/phpmyadmin/ /var/www/html/phpmyadmin

which I edited to :

sudo ln -s /usr/share/phpmyadmin/ /sharedfolders/www/phpmyadmin

I can now browse to the myPhpAdmin page

Hope this helps someone else in the future
