我正在尝试在docker中设置太阳能云。 我正在使用docker-compose来启动云。 我创建了一个云，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是很冷的。 问题是当它在装载的卷中创建集合以在 docker 外部的计算机上进行备份时。 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。 当我通过以下方式创建分布式集合时
docker exec -it solr1 /opt/solr/bin/solr create_collection -c publications -s 4 -rf 2 -p 8983
我在容器中有两个内核的目录，例如对于 solr1 有
/opt/solr/server/solr/publications_shard2_replica_n6
和
/opt/solr/server/solr/publications_shard4_replica_n14
对于分片2，我有 我在容器中有一个包含两个内核的目录，例如对于 solr1 有
/opt/solr/server/solr/publications_shard1_replica_n1
和
/opt/solr/server/solr/publications_shard3_replica_n8
等。 内核的名称是动态的。
如何在我的卷目录中创建它们，即
/root/solr/cores
我docker-compose.yml如下

我找到了解决方案。需要在docker-compose.yml文件中添加一个-t参数并/opt/solr/server/solr/mycores交付数据目录。 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'
