Did you try the instructions from docker’s official site? All it should take is either adding their repos and apt installing the few necessary packages or downloading and executing the script found at https://get.docker.com

I am using raspsberry pi as a docker host. Though, I was able to create some virtual IP's in my host machine, but that not actually doing what I wanted to. So, is it possible to achieve through some short of plugin? Its possible on podman via CNI plugins leasing ips podman . But, something like that on docker would be very useful for my projects. There is a plugin docker net dhcp, but its x86 only, also there is another experimental driver experimental libinetwork driver that I am not sure how to install or it is also x86. Any help will be highly appreciated.

docker net dhcp : This shows error : [email protected]:~ $ sudo docker plugin ls ID NAME DESCRIPTION ENABLED c9ff714bd90b devplayer0/net-dhcp:latest Docker host bridge DHCP networking false [email protected]:~ $ sudo docker plugin enable c9ff714bd90b Error response from daemon: dial unix /run/docker/plugins/c9ff714bd90b282648abed6a833812ad1a6e56d5cdfa1270a80046c4acc98eae/net-dhcp.sock: connect: no such file or directory
