Summary of the issue you are facing:
I’m trying to set up the Deploy Daemon for the api but I cannot get it to register on the port 2375.
Steps to replicate it (hint: details matter!):
- Install Docker on Nextcloud Server
- Install and run the nextcloud-appapi
- Try to setup the daemon in the AppAPI in Nextcloud
The instance cannot be found according to testing the connection in Nextcloud. If I look at the docker instance in the server, the container is running fine but there is no port associated and if I look at the ports running on the server, that one doesn’t show up. I’m not sure if there is a trick to exposing the port to the host of the server.
