Dual-line MOTD with docker-compose

[Ahptt]

Hello, this is a rather minor issue but I'm unable to perform a line break in my MOTD. Also, when manually editing a MOTD in the server.properties, I'm able to add spaces to center my MOTD. When my docker-compose runs, the spaces aren't passed along. After passing the below MOTD in my compose file, half of the message is oddly placed further down the server.properties file.

docker-compose.yml
server.properties

Newlines in server properties values need an extra backslash to escape the backslash 😃

This

version: "3"

services:
  mc:
    image: itzg/minecraft-server
    environment:
      EULA: "true"
      MOTD: "line one\nline two"
    ports:
      - "25565:25565"

results in

Worked like a charm. Of course it's the one backslash! 🤣

FYI I'm going to add some info to the MOTD section since that one character makes a big difference 😃

This no longer appears to work. \\n now becomes \\\\n in server.properties. I've also tried with \u005Cn and \u005C\n, but both cause this error:

[mc-image-helper] 18:57:43.308 ERROR : 'set-properties' command failed. Version is 1.38.14
java.lang.IllegalArgumentException: character to be escaped is missing

However, using YAML's multi-line syntax, it works:

# example
MOTD: |
  line one
  line two

What you discovered matches what is documented

https://docker-minecraft-server.readthedocs.io/en/latest/configuration/server-properties/#message-of-the-day

I should also include a compose/yaml example like you ended up with.

Docs have been updated. Thanks for pointing this out @Pyroglyph
