Map NetherNet properties and fix healthcheck - #675

TRANSPORT/SERVER_UDP_PORTS/SERVER_IP were ignored; latest BDS also fails the RakNet healthcheck. Leave TRANSPORT unset so pinned RakNet versions keep zip defaults.

I think it should be opt-in. Only the given environment variables are applied to properties, so normally the bedrock supplied defaults have to be assumed correct. If not, that’s Mojang’s issue to fix. |

There was a problem hiding this comment.
I would like to enhance mc-monitor to support this; however this wrapper script is needed even for that and this is a good reference implementation.

Summary
TRANSPORT,SERVER_UDP_PORTS, andSERVER_IPthroughproperty-definitions.jsonso env vars are written intoserver.propertieslike the other BDS keys. Fixes ignoredTRANSPORT=/SERVER_UDP_PORTS=on current BDS (see Nethernet and latest version (1.26.51.1) - unable to connect #673).EXPOSE 19132/tcp. Healthcheck isbds-healthcheck:GET /v1/joinonly whenTRANSPORT=nethernet, otherwise the existingmc-monitorRakNet ping.examples/nethernet/compose.yml. Existing compose/k8s examples are unchanged.TRANSPORTis not defaulted in the Dockerfile so pinned RakNetVERSION=still gets zip defaults.Open question
Should
