docker - 通过 Docker-Compose 为 ElasticSearch 使用持久主机卷

Question

使用以下 docker-compose.yml 运行 Elasticsearch正在抛出错误

Java.nio.file.AccessDeniedException: /usr/share/elasticsearch/data/nodes

这似乎是由于试图挂载 /usr/share/elasticsearch/data在 Docker 容器中到 ./data/elasticsearch/data在主机上。

尝试设置 user: "1000:1000"确定以下信息后，但仍然收到相同的错误。

/usr/share/elasticsearch/data/nodes 的所有者/组成为 elasticsearch:elasticsearch

/usr/share/elasticsearch/data 的所有者/组成为 elasticsearch:root

uid=1000(elasticsearch) gid=1000(elasticsearch) groups=1000(elasticsearch)

问题:是否可以挂载到主机卷 ./data/elasticsearch/data ，而不是使用匿名或命名卷？

使用 docker-compose 1.24.0、docker 19.03.6-rc1、Ubuntu 18.04.3。

docker-compose.yml

version: '3'
services:

  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch-oss:6.8.2
    user: "1000:1000"
    volumes:
      - ./data/elasticsearch:/usr/share/elasticsearch/data
    environment:
      - http.host=0.0.0.0
      - transport.host=localhost
      - network.host=0.0.0.0
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:

Answer 1

在自行启动容器并对其进行检查后，我看到数据目录归 1000:root 所有.所以我只是在目录上复制了这个来绑定(bind)和弹性启动，没有任何问题:

$ cd /tmp
$ mkdir -p so_test_elastic/data
$ cd so_test_elastic
$ sudo chown 1000:root data
$ docker run -it --rm --name es -v $(pwd)/data:/usr/share/elasticsearch/data docker.elastic.co/elasticsearch/elasticsearch-oss:6.8.2
