Does anybody know how to create a custom bridge network in Portainer? I am testing a NanoPi M4 on OMV 5 and am unable to setup Nextcloud using Letsencrypt/Nextcloud/Duckdns/Mariadb containers because docker-compose does not work on aarch64 boards. I have read about it in Docker and Portainer documentation but fail to find instructions on how to actually create a custom bridge network in order to connect the containers together.
Or is there another way to do it?
