1、进入容器

[root@localhost docker]# docker exec -it mongodb mongosh
Current Mongosh Log ID: 66a8ce38d0b85e052bb78f05

2、查看数据库列表

test> show dbs
admin    40.00 KiB
config  108.00 KiB
local    72.00 KiB

3、如果数据库不存在，则创建数据库，否则切换到指定数据库

懒加载创建

test> use atguigu
switched to db atguigu
atguigu> show dbs
admin    40.00 KiB
config  108.00 KiB
local    72.00 KiB

4、删除当前数据库

atguigu> db.dropDatabase()
{ ok: 1, dropped: 'atguigu' }
atguigu>
