Docker install mongo (express)

One, command installation

1. Check the available MongoDB version

Link: hub.docker.com-mongo .
Use the latest version this time: latest
can use the docker search mongo command to view the available images

2. Installation steps

(1) Pull the image

docker pull mongo:latest

(2) Run the container

//持久化加--volume /usr/local/mongodata:/data/db
docker run -itd --name mongodb -p 27017:27017 mongo --auth

  -p 27017:27017 ：映射容器服务的 27017 端口到宿主机的 27017 端口。外部可以直接通过 宿主机 ip:27017 访问到 mongo 的服务。
  --auth：需要密码才能访问容器服务。

(3) Test after successful installation.
View running information by command docker ps
Use the following commands to add users and set passwords, and try to connect.

$ docker exec -it mongo mongo admin
//创建一个名为 admin，密码为 123456 的用户。
>  db.createUser({
    
     user:'admin',pwd:'123456',roles:[ {
    
     role:'userAdminAnyDatabase', db: 'admin'},"readWriteAnyDatabase"]});
//尝试使用上面创建的用户信息进行连接。
> db.auth('admin', '123456')

(4) Install mongo-express

//拉取镜像
docker pull mongo-express:latest
//运行容器
docker run -itd --name mongo-express -p 8081:8081 --link mongodb:mongo --env ME_CONFIG_MONGODB_ADMINUSERNAME='admin' --e
nv ME_CONFIG_MONGODB_ADMINPASSWORD='123456' mongo-express

Two, yml installation

Create a new stack.yml file in the installation directory

# Use root/example as user/password credentials
version: '3.1'

services:

  mongo:
    image: mongo
    restart: always
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example

  mongo-express:
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example

Execute the command
docker stack deploy -c stack.yml mongo
(or docker-compose -f stack.yml up)
background execution: -d
