How to set new logging configuration settings as environment variables in Kibana docker container

[apt-get_install_skil]

Hey there,

we're running Kibana in a docker container and all configuration is provided via injected environment variables - hence we do not mount a kibana.yml file.

As stated in the documentation, the "syntax" for the docker environment is different.

E.g. elasticsearch.hosts is ELASTICSEARCH_HOSTS.

So far so good.

However, I don't know how to "translate" the settings for the new logging capabilities listed here.

I've tried to built

logging:
  appenders:
    console-meta:
      type: console
      layout:
        type: pattern
        pattern: "[%date] [%level] [%logger] [%meta] %message"
  root:
    appenders: [default, console-meta]

the following way but without success

LOGGING_APPENDERS[]=[CONSOLE-META]
LOGGING_APPENDERS_CONSOLE-META_TYPE=console
LOGGING_APPENDERS_CONSOLE-META_LAYOUT_TYPE=pattern
LOGGING_APPENDERS_CONSOLE-META_LAYOUT_PATTERN="[%date] [%level] [%logger] [%meta] %message"

LOGGING_ROOT_LEVEL=info
LOGGING_ROOT_APPENDERS[]=[default, CONSOLE-META]

This also didn't work:

LOGGING_APPENDERS_0=console-meta
LOGGING_APPENDERS_0_TYPE=console
LOGGING_APPENDERS_0_LAYOUT_TYPE=pattern
LOGGING_APPENDERS_0_LAYOUT_PATTERN="[%date] [%level] [%logger] [%meta]"

LOGGING_ROOT_LEVEL=info
LOGGING_ROOT_APPENDERS_0=default
LOGGING_ROOT_APPENDERS_1=console-meta

If possible I'd like to avoid mounting a kibana.yml file but I'm not sure how to handle the arrays.

Could you please clarify?
Thanks in advance.
