Provide mechanism similar to rcon-cli about docker-minecraft-bedrock-server

[itzg]

Actually that's a great question...but unfortunately they haven't implemented rcon in the bedrock edition so including the cli wouldn't help.

Over here #8 (comment) I show a work around where you can docker attach to the bedrock container and issue commands.

There was a ticket logged in September 2018 on Mojang's bug-tracker Jira about the lack of RCON in BDS, but it was invalidated as it was a feature request, not a bug.

Feature requests should go to the suggestions subreddit.

I have made such a request here.

Off the back of the Reddit request, it has now been added to the feature parity list on the official wiki.

I guessed that was the case with rcon-cli thanks @itzg

Appreciate the pointer - just a quick one for yourself (or Nitrosito really) - what would the docker-compose equivalent look like? Not having much luck with:

...snip...
    ports:
      - 19132:19132/udp
    restart: unless-stopped
    command: run --rm -i  -e EULA=TRUE

Then,

# docker attach minecraft-bedrock
[2019-11-11 22:07:22 INFO] Server started.
/help
^P/help
help
^Ztime="2019-11-11T22:07:32Z" level=debug msg="Forwarding signal" signal=stopped

[itzg]

Here is a compose file that allows for using docker attach where it's the last two lines that are relevant:

version: '3.3'

services:
  bedrock:
    image: itzg/minecraft-bedrock-server
    environment: 
      EULA: "TRUE"
    ports:
      - 19132:19132/udp
    stdin_open: true
    tty: true

BTW, the command field is tempting, but it's typically for specifying the command arguments to run within the container.

@itzg That works perfectly, nice trick indeed, quite correct in my assumption about the command field - noted.

Tab-completion would be nice if it worked but this is way better than nothing at all, thanks!

Awesome @macchie ! I can add that to the community solutions section if you're interested.

Of course! :)
I'll make sure to make it better and more useful!

Thank you very much! I'm currently working on server commands feedback on Telgram and the HTTP API to execute commands.

how download?

Hello, I found a way to send commands to the server, when it was not started with the -it flags.

The docker image used is very simple so it lacks a few basic linux commands, lis ps.
Anyway, this is what you have to do:

1. get bash on the container with docker exec -it <bedrock id> /bin/bash
2. send your command to the server process' STDIN echo "<your command>" > /proc/10/fd/0

That is it.
The process that has the console running is /data/bedrock_server-1.19.11.01, you can find the correct id with
find /proc -mindepth 2 -maxdepth 2 -name exe -exec ls -lh {} \; 2>/dev/null

Since we have the same image, I would guess we get the same PID for that process: 10

so you can just send commands like
echo "gamerule showcoordinates true" > /proc/10/fd/0
echo "op myuser_please" > /proc/10/fd/0

And you can be a little more clear? For the little ones in this topic. And how to do it on windows?

[mattholy]

Actually you can use the docker api to send commands into the Minecraft server. I believe it’s the best practice when you want to control your server by telegram

[itzg]

@mattholy can you clarify that? The previous suggestion made sense to me adapt into a script that can be exec'ed in the container.

please read this https://docs.docker.com/engine/api/v1.41/#tag/Container/operation/ContainerAttach
if still a question, fell free to ask me

[itzg]

Now I understand. Doesn't need to be an API call though

The suggestion from @Bass-03 has now been bundled into the image as send-command and documentation has been updated:
