Logstash 無法加載，文件不可讀

Question

嘗試按照此答案在 MongoDB 和 Elasticsearch 之間使用MongoDbJdbcDriver進行同步。 我使用docker-compose進行開發，這就是logstash ：

  logstash:
    image: logstash:7.9.1
    container_name: logstash
    volumes:
      - ./logstash/jars/gson-2.8.6.jar:/usr/share/logstash/logstash-core/lib/jars/gson-2.8.6.jar:ro
      - ./logstash/jars/mongojdbc2.3.jar:/usr/share/logstash/logstash-core/lib/jars/mongojdbc2.3.jar:ro
      - ./logstash/jars/mongo-java-driver-3.12.6.jar:/usr/share/logstash/logstash-core/lib/jars/mongo-java-driver-3.12.6.jar:ro
      - ./logstash/config/pipelines.yml:/usr/share/logstash/config/pipelines.yml
      - ./logstash/pipeline/mongo-to-elasticsearch.conf:/usr/share/logstash/pipeline/mongo-to-elasticsearch.conf
    command: logstash
    depends_on:
      - elasticsearch

我運行docker-compose up它給出了這個錯誤：

...
logstash         |   Error: unable to load mongojdbc2.3.jar from :jdbc_driver_library, file not readable (please check user and group permissions for the path)
logstash         |   Exception: LogStash::PluginLoadingError
...

我已經在我的機器上檢查了mongojdbc2.3.jar文件權限，為我和 docker 組提供了讀寫權限。 但是，當我檢查logstash容器內部時，所有者不是root而是logstash ：

// ls -l /usr/share/logstash/logstash-core/lib/jars

...
-rw-r--r-- 1 logstash logstash  2315317 Jul 24 15:13 mongo-java-driver-3.12.6.jar
-rw-r--r-- 1 logstash logstash    83500 Sep  8 01:30 mongojdbc2.3.jar
-rw-rw-r-- 1 logstash root       107210 Sep  1 23:32 org.eclipse.core.commands-3.6.0.jar
...

我嘗試更改容器內的所有權，但由於沒有sudo權限，因此無法更改。

請幫忙，如何在 MongoDB 和 Elasticsearch 之間成功同步？

嘗試創建包含 jars 的新圖像

  logstash:
    build: ./logstash/
    container_name: logstash
    volumes:
      - ./logstash/config/pipelines.yml:/usr/share/logstash/config/pipelines.yml
      - ./logstash/pipeline/mongo-to-elasticsearch.conf:/usr/share/logstash/pipeline/mongo-to-elasticsearch.conf
    command: logstash
    depends_on:
      - elasticsearch

./logstash/Dockerfile

FROM docker.elastic.co/logstash/logstash:7.9.1

COPY ./jars/ /usr/share/logstash/logstash-core/lib/jars
