This article mainly introduces the process of installing and configuring docker and portainer in openmediavault. portainer is a docker image.

1. Environment

Device:
nanopi-m2v4
系统：
Armbian 21.02.3 Buster with Linux 4.4.213-rk3399
Distributor ID: Debian
Description: Debian GNU/Linux 10 (buster)
Release: 10
Codename: buster
omv version:
5.6.4-1 (Usul)

2. Install docker

Enter 系统- OMV-Extras, install docker, most of which cannot be successful here, and need to be installed on the command line.

Refer to Tsinghua University Open Source Software Mirroring Station-Docker Community Edition image usage help
If you have installed docker in the past, delete it first:

sudo apt-get remove docker docker-engine docker.io

First install dependencies:

sudo apt-get install apt-transport-https ca-certificates curl gnupg2 software-properties-common

Depending on your distribution, what follows varies. The distribution I am using is Debian.
Trust Docker's GPG public key:

curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -

Pay attention to add the software warehouse according to the hardware architecture, mine is the arm architecture.
Add software repository:

echo "deb [arch=armhf] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/debian \
     $(lsb_release -cs) stable" | \
    sudo tee /etc/apt/sources.list.d/docker.list

Finally install:

sudo apt-get update
sudo apt-get install docker-ce

Modify the domestic source:
edit or create a new configuration file /etc/docker/daemon.json, remember to add dns, and the reasons for adding dns refer to: ①The /etc/resolv.conf in the Docker container is inconsistent with the host machine, several ways to configure dns; ②Docker container to modify dns;

{
    
    
    "registry-mirrors": ["https://registry.docker-cn.com"],
    "dns" : ["114.114.114.114","8.8.8.8"]
}

3. Install Portainer

Step 2 After the installation, start to install portainer. It cannot be installed directly through omv-extras, but according to my situation, after adding dns analysis, enter omv-extras and click install directly.
You can first test whether the problem encountered is the same as mine, and then decide whether to follow the next operation.
Command line run:

docker search portainer

If the output is:

Error response from daemon: Get "https://index.docker.io/v1/search?q=portainer&n=25": dial tcp: lookup index.docker.io: device or resource busy
或
Error response from daemon: Get "https://index.docker.io/v1/search?q=portainer&n=25": dial tcp: lookup index.docker.io: no such host

Just /etc/resolv.confadd dns resolution at the end of the file:

nameserver 127.0.0.1
nameserver 114.114.114.114
nameserver 8.8.8.8

Then run again:

docker search portainer

The output is:
