查看mongo镜像

 docker images mongo

运行安装命令：

docker run --name mongodb -p 27017:27017 -d mongo --auth

为MongoDB添加管理员用户
进入MongoDB

docker exec -it f61df2709f78 mongo admin

f61df2709f78是你的MongoDB容器的id

创建一个 admin 管理员账号：

db.createUser({ user: 'root', pwd: 'root', roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] });

退出
exit

操作如下

MongoDB shell version v4.0.10
connecting to: mongodb://127.0.0.1:27017/admin?gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("176dd8db-5cd5-4165-8e06-b8eb9a62501a") }
MongoDB server version: 4.0.10
Welcome to the MongoDB shell.

> db.createUser({ user: 'root', pwd: 'root', roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] });
Successfully added user: {
	"user" : "root",
	"roles" : [
		{
			"role" : "userAdminAnyDatabase",
			"db" : "admin"
		}
	]
}
> exit
bye

创建普通用户、密码和数据库
以 admin 用户身份进入mongo ：

docker exec -it f61df2709f78 mongo admin

对 admin 进行身份认证：
PS:就是上一步创建的管理员账号密码

 db.auth("root","root");

创建 用户、密码和数据库：

db.createUser({ user: 'swen', pwd: 'swen123456', roles: [ { role: "readWrite", db: "app" } ] });

操作如下

[root@bogon ~]# docker exec -it f61df2709f78 mongo admin
MongoDB shell version v4.0.10
connecting to: mongodb://127.0.0.1:27017/admin?gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("ee4b71ce-cd2d-4a60-97a7-9a2ea7c30017") }
MongoDB server version: 4.0.10
> db.auth("root","root");
1
> db.createUser({ user: 'swen', pwd: 'swen123456', roles: [ { role: "readWrite", db: "app" } ] });
Successfully added user: {
	"user" : "swen",
	"roles" : [
		{
			"role" : "readWrite",
			"db" : "app"
		}
	]
}
> exit
bye

登录 APP 数据库
以 admin 用户身份进入mongo ：

 docker exec -it f61df2709f78 mongo admin

对 swen 进行身份认证：

db.auth("swen","swen123456")

切换数据库

use app

操作如下

[root@bogon ~]# docker exec -it f61df2709f78 mongo admin
MongoDB shell version v4.0.10
connecting to: mongodb://127.0.0.1:27017/admin?gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("d551ced7-b8c8-48d3-a5f5-32a4813e3d7c") }
MongoDB server version: 4.0.10
>  db.auth("swen","swen123456")
1
> use app
