docker 网络

# 创建 mongo_network 网络
docker network create mongo_network
# 查看网络
docker network list
# 容器连接到 mongo_network 网络
docker network connect mongo_network mongo
# 断开容器 mongo_network 网络
docker network disconnect mongo_network mongo

mongod.conf

# 容器内查看 mongod.conf
cat /etc/mongod.conf.orig

• 缩主机上创建 mongo/configdb/mongod.conf

# 数据
storage:
  dbPath: /data/db
  journal:
    enabled: true
# 日志

部署 MongoDB

• https://hub.docker.com/_/mongo

# MongoDB镜像
docker pull mongo:4
docker run --name mongo \
--network mongo_network \
-p 27017:27017 \
-v $PWD/mongo/data:/data/db \
-v $PWD/mongo/configdb:/data/configdb \
-v $PWD/mongo/logs:/var/log/mongodb \
-e MONGO_INITDB_ROOT_USERNAME="root" \
-e MONGO_INITDB_ROOT_PASSWORD="4NuMDwIzp05BdKp7Bdmf" \
-d mongo:4 \
--config /data/configdb/mongod.conf

• 指定服务执行器与缓存大小

docker run --name mongo \
--network mongo_network \
-p 27017:27017 \
-v $PWD/mongo/data:/data/db \
-v $PWD/mongo/configdb:/data/configdb \
-v $PWD/mongo/logs:/var/log/mongodb \
-e MONGO_INITDB_ROOT_USERNAME="root" \
-e MONGO_INITDB_ROOT_PASSWORD="4NuMDwIzp05BdKp7Bdmf" \
-d mongo:4 \
--config /data/configdb/mongod.conf \
--serviceExecutor adaptive --wiredTigerCacheSizeGB 1.2

部署 mongo-express

• https://hub.docker.com/_/mongo-express

# mongo-express镜像
docker pull mongo-express:1.0.2
docker run --name mongo-express \
    --network mongo_network \
    -p 8081:8081 \
    -e ME_CONFIG_MONGODB_SERVER=mongo \
    -e ME_CONFIG_MONGODB_ADMINUSERNAME="root" \
    -e ME_CONFIG_MONGODB_ADMINPASSWORD="4NuMDwIzp05BdKp7Bdmf" \
    # 设置 mongo-express 登录账号密码
    -e ME_CONFIG_BASICAUTH=true \
    -e ME_CONFIG_BASICAUTH_USERNAME="admin" \
    -e ME_CONFIG_BASICAUTH_PASSWORD="123456" \
    -d mongo-express:1.0.2

• 查看默认登录账号密码

# 进入 mongo-express 容器内
docker exec -it mongo-express /bin/bash
# 查看config.default.js
cat /app/config.default.js

注意： 默认登录账号密码是 admin/pass，docker配置中已经将登录账号密码设置为 admin/123456

docker exec -it mongo /bin/bash
# 或直接进容器内的 MongoDB shell
docker exec -it mongo mongo

# 切换数据库
> use admin
# 管理员身份连接（MONGO_INITDB_ROOT_USERNAME配置值）
> db.auth("root",passwordPrompt())
# 输入密码（MONGO_INITDB_ROOT_PASSWORD配置值）

# 显示数据库
> show dbs
# 显示用户
