概要

公式のDockerイメージを利用してKibanaを利用しているとき、kibana.ymlをマウントしないでできる範囲ってどこなの？　ということが気になったので、ちょっと調べてみた。

ポイントは、docker cmdに割り当たっている /usr/local/bin/kibana-dockerの中にありました。

指定できる環境変数

kibana-dockerの中には、以下の設定項目が用意されています。

また、冒頭にはこのように記述されています。

# Run Kibana, using environment variables to set longopts defining Kibana's
# configuration.
#
# eg. Setting the environment variable:
#
#       ELASTICSEARCH_STARTUPTIMEOUT=60
#
# will cause Kibana to be invoked with:
#
#       --elasticsearch.startupTimeout=60

つまり環境変数で指定するときは、大文字で、ピリオドを_にした文字列で指定すれば良いということになりますな。

たとえばKibanaの日本語化

なので、i18n.localeという設定項目であれば、環境変数は I18N_LOCALE=ja-JP　とすれば良いということなりますね。

  kibana:
    image: docker.elastic.co/kibana/kibana:7.2.0
    container_name: kibana
    environment:
      - I18N_LOCALE=ja-JP
    ports:
      - 5601:5601
    depends_on:
      - elasticsearch
    links:
      - elasticsearch:elasticsearch
    networks:
      - esnet
