Minecraft Bedrock Server Docker FAQ

Q1. How do i attach to the Minecraft Bedrock Server console when using this Docker container?

A1. Minecraft Bedrock Server uses a program called 'screen' in order to allow you to connect and disconnect from the running console. In order to connect to the console once the container is running you would issue the following command from your hosts shell:-

docker exec -u nobody -it <name of container> screen -r minecraft

You will then be able to execute 'help' in order to see available commands.

In order to disconnect from the running Minecraft console without stopping the server, you press:-

CTRL + a then release and press d

Use command 'clear' to clear the screen of any previous output, you can then re-connect to the session again if required using the command above.

Note If you do press CTRL + c by accident then you will need to restart the container in order to be able to connect to the console again, as this will kill the running Minecraft Server.

Q2. I'm struggling to work out how you can add a texture pack to the Minecraft Bedrock server, can you please give me a step by step guide on how to do this?

A2. Sure!, the steps below were taken from a forum post by member 'PeteAsking':-

  1. Stop the Minecraft Bedrock Server container.
  2. Download a texture pack, e.g. https://mcpedl.com/fuserealism-resource-pack/ ensuring the filename does not contain spaces, change the extension to .zip
  3. Copy the downloaded texture pack to /config/minecraft/resource_packs/
  4. Also copy the texture pack to /config/minecraft/worlds/<name of your world>/resource_packs/ - this is so people joining get the texture pack installed on their Minecraft client, otherwise they must have it pre-installed on their device.
  5. Rename file /config/valid_known_packs.json to a new name.
  6. Start and stop the container to auto regenerate the above file with the correct UUID and version values for the texture pack.
  7. Open the file /config/valid_known_packs.json and make a note of the 'uuid' value - this will be required in a step below.
  8. Create a file /config/minecraft/worlds/<name of your world>/world_resource_packs.json with the following content, replacing the value of 'pack_id' with the uuid identified in step 7.:-
[
    {
        "pack_id" : "<value of uuid in step 7.>",
        "version" : [ 0, 0, 1 ]
    }
]
  1. Open the file config/server.properties and change texturepack-required=true if you want to force people to use the pack. otherwise leave it false to make the texture pack optional.
  2. Start the Docker container.
  3. The texture pack should now be visible in your Minecraft world.

Note If you at any stage get the message 'invalid_resource_pack file' then the pack you downloaded is incompatible with the version of Minecraft Bedrock server that you are running, try another texture pack.

Q3. I would like to execute a specific Minecraft Bedrock console command on a scheduled basis, how can i do this?

A3. You can execute arbitrary commands on the Minecraft Bedrock console by re-attaching to the 'screen' session and then 'stuff'ing commands into the input buffer, syntax is as follows:-

docker exec -u nobody -i <name of container> screen -S minecraft -p 0 -X stuff "<command to execute>^M"

To verify this worked simply re-attach to the session (as documented above in Q1) and you should see the command has been executed.

Notes
If you do re-attach to verify the command executed and then try to run another arbitrary command from another exec'd session then you will see a 'permission denied' message and the command will NOT execute, you need to detach from the running session for the command to execute correctly.

If you want to run this on a scheduled basis either from a bash script or via cron job then you will need to ensure you do not specify the '-t' flag for the command, otherwise it will attempt to create a terminal which will not be available when run via cron/bash (non interactive).

Q4. I can see in the log file /config/supervisord.log that the Minecraft server has started but when i attempt to connect to the console via the web ui i see the message There is no screen to be resumed matching Minecraft, what is the cause and how can i fix it?.

A4. This issue can be related to the browser used to connect to the web ui, switching browser normally allows a user to authenticate and view the console.

Q5. I have not hard set the 'seed' value for my World in Minecraft Bedrock, how do i now know what the auto generated seed value is?.

A5. One way to identify the 'seed' is by using Minecraft Pocket Edition (PE), this can be installed from the 'Google Play' Store, once installed connect to your world then click on the icon at the top that looks like a pause symbol, click on Settings, then click on World, then click on Game and scroll down and the seed value should be shown (its greyed out as you cannot change this from in-game).
