Connecting to a server's CLI

docker exec -it <container_name> rcon-cli --password thanksitzg https://github.com/itzg/docker-minecraft-server#interactive-and-color-console https://github.com/itzg/docker-minecraft-server#use-rcon-commands

Updating MC-Router mappings

MC-Router must be running for all active MC connections. Restarting it kicks everyone off their servers

To update the mappings while running, use docker exec mc-router /mc-router --mapping <new-mapping string>

Before Starting a Server

Check the following server.properties values:

Parameter	Value	Why
allow-flight	true	Many modded features trigger Minecraft's flight detection. Allow flight to prevent wrongful bans.
enable-rcon	true	This overrides any rcon settings in the compose file. Enable rcon to interact with the server's command line
max-tick-time	600 normally, 120000 when pre-genning chunks	Increase the max tick time to prevent the hang watchdog from killing the server when pregenning chunks
rcon.password	thanksitzg	Set a simple password to protect the rcon port
rcon.port	25575	Set this to what itzg's rcon-cli expects as default
view-distance	10 for lightweight servers, 6 for heavy servers	View distance has great impact on server load
