docker 启动 solo 一天不到占用磁盘 50G

该虚拟机只有容器 一个是 maria db 另外一个 solo ,光 solo 就占用了 46 个 G 的磁盘。

删除 solo 容器后存储又恢复

[root@VM_0_9_centos containers]# docker rm -f solo
solo

启动命令

docker run --detach --name solo --network=host     --env RUNTIME_DB="MYSQL"     --env JDBC_USERNAME="root"     --env JDBC_PASSWORD="xxxx"     --env JDBC_DRIVER="com.mysql.cj.jdbc.Driver"     --env JDBC_URL="jdbc:mysql://127.0.0.1:3306/solo?useUnicode=yes&characterEncoding=UTF-8&useSSL=false&serverTimezone=UTC"     b3log/solo --listen_port=8080 --server_scheme=http --server_host=www.xxxxx.com --server_port=8080

怎么解决这个问题？除了定时去删除启动容器？
