Docker中的Solr，如何在挂载卷目录中创建共享的分布式集合

Question

我正试图在 docker 内设置太阳云。我正在使用 docker-compose 来启动云。我创建了一个云，其中包含 3 个动物园管理员和 4 个 solrs（solr1、solr2、solr3、solr4）容器。创建 4 个分片和 2 个副本的分布式集合很酷。问题是当它在已安装的卷中创建集合以在 docker 之外的机器上进行备份时。我可以为每个容器将目录卷从机器挂载到 solr 云，但我无法在那里创建集合。当我通过

创建分布式集合时

docker exec -it solr1 /opt/solr/bin/solr create_collection -c publications -s 4 -rf 2 -p 8983

我在容器中有两个核心的目录，例如对于 solr1 有

/opt/solr/server/solr/publications_shard2_replica_n6

和

/opt/solr/server/solr/publications_shard4_replica_n14

对于 shard2，我有我在容器中有一个包含两个核心的目录，例如对于 solr1 有

/opt/solr/server/solr/publications_shard1_replica_n1

和

/opt/solr/server/solr/publications_shard3_replica_n8

等核心名称是动态的。

如何在我的卷目录中创建它们

/root/solr/cores

我的docker-compose.yml如下

version: "3.1"
services:
  solr1:
    image: solr:latest
    environment:
      - JVM_OPTS=-Xmx12g -Xms12g -XX:MaxPermSize=1024m

我找到了解决办法。需要在 docker-compose.yml 文件中添加 -t 参数并提供数据目录 /opt/solr/server/solr/mycores。下面编辑的行

command: bash -c '/opt/solr/bin/solr start -f -z zookeeper1:2181,zookeeper2:2182,zookeeper2:2183 -m 1g -t /opt/solr/server/solr/mycores'
