Docker Compose Fails on Nanopi M4 and OMV5

I have been trying to install Plex using docker compose according to @macom‘s [How-To] on a NanoPi M4 and OMV5. My docker-compose.yml file fails to deploy when I send the command docker-compose up -d. I get the response /usr/local/bin/docker-compose: line 1: Not: command not found. I know docker-compose is installed because I just ran apt install docker-compose which returns that the current version is already installed. Here’s a copy of my yml file:

---
version: "2"
services:
  plex:
    image: linuxserver/plex
    container_name: plex
    network_mode: host
    environment:
      - PUID=1001
      - PGID=100
      - VERSION=public
    volumes:
      - /srv/dev-disk-by-label-m4disk1/AppData/Plex:/config
      - /srv/dev-disk-by-label-m4disk1/AppData/Transcode:/transcode
      - /srv/dev-disk-by-label-m4disk1/Media/Movies:/Movies
      - /srv/dev-disk-by-label-m4disk1/Media/TV:/TV
      - /srv/dev-disk-by-label-m4disk1/Media/Music:/Music
      - /srv/dev-disk-by-label-m4disk1/Media/Photos:/Photos
      - /srv/dev-disk-by-label-m4disk1/Media/Videos:/Videos
    restart: unless-stopped

Can anyone please help with this?

Well I guess that solves my problem...sort of.

That has been the frustrating thing for me because docker-compose has worked beautifully for me on an Odroid H2 which has an Intel processor in it.

Is that also why Cockpit refuses to install on the NanoPi M4? It works perfectly on the H2 and an old HP Compaq?

Now to figure out how to create a custom bridge network on the M4 using Portainer (or command line) because getting Nextcloud set up on the NanoPi M4 (OMV5) has been my end game. Plex in Portainer is a breeze. I’ll start a fresh thread for that.

@ryecoaaron thanks for looking into this and the (sad) solution.

@ryecoaaron is there a way to install Cockpit without the kvm modules? I’ve seen instances of it on arm boards on the web but never could figure out how to install it with OMV5.

There are instructions for Jessie and Stretch here but nothing about Buster. I’ll keep looking.

Or This site where it shows a bunch of screenshots and gives these two lines:
apt -y install Cockpit
systemctl enable cockpit.socket

I have tried that several times and it always fails. Returns something about that kvm module being not available. I’m away from my computer right now so I don’t recall the exact response.

Fix in omv-extras 5.1.3

Works! Thank you very much.

Quote from macom

Alternative would be to uninstall and install from CLI with apt-get

There is a arm64 version of the Buster distro of Docker Here and the first seven hits when I search "Install Docker on Debian Buster" look doable. But questions loom? what will this do to OMV-Extras? Hey, I don't have any data on the machine. What the heck. I'm sure it is more complicated than I am seeing.

Any advice?

I’m sorry. I need to get on my computer and see but as far as I know Portainer works and Cockpit works now but docker compose and docker network does not. I thought that was what you were talking about in the thread just above with @Morlan. I’m trying by hook or by crook to get Nextcloud/Letsencrypt working on the M4 in OMV5, via either compose or a custom network. I have it on an Odroid H2 (amd64) but I’m not (never?) content.

I’ll go back and see. When I said “Works!” I meant Cockpit installs from OMV-Extras. The terminal works great and the docker image download is wonderful, allowing me to download multiple images in succession without having to wait for each completion. I still prefer Portainer for building containers, but compose via command line on the H2 is so slick and (I’m too old to use this word) cool. I want it on the M4.
