Docker it’s a software which allows you to run containers(apps) into a server(or desktop) WO too much hassle and compatibility issues, docker containers comes with everything needed to run the program independent of which distro you are using, you just need the docker image be available for your architecture and you will be able to run the container on any software/hardware you have.
In Armbian+orange pi you just need to install docker(I suggest you to use docker.io package over debían derivates like Armbian), restart your server and then run the “docker run” command:
Sudo apt install docker.io
Sudo restart -f
And then run the docker command and it will download, install and run the container into your server(make sure you use the appropriate flags into it).
I suggest you to read some information about the use of docker on servers for you to get more into it’s use.
