我正在尝试备份 solr 云集合。Solr 和 Zookeeper 在 Docker 容器中运行。有3个solr（使用端口：8981,8982,8983）和3个ZKs容器正在运行。我将 docker 卷传递给 solr 容器

volumes:
    - solr_backups:/solr-backups/storage

在 Dockerfile 中，构建并给出了文件夹chmod 777。因此，所有 solr 容器都会将该文件夹视为网络共享（我假设）。

执行中

$ curl "localhost:8981/solr/admin/collections?action=BACKUP&name=test1&collection=myColl&location=/solr-backups/storage"

返回以下内容

...
