Docker 安装 MongoDB

docker pull mongo:3.2

等待下载完成后，我们就可以在本地镜像列表里查到 REPOSITORY 为 mongo，标签为 3.2 的镜像：

docker images | grep mongo

方法二、通过 Dockerfile 构建

创建Dockerfile

首先，创建目录 mongo，用于存放后面的相关东西：

mkdir -p ./mongo  ./mongo/db

db目录将映射为 mongo 容器配置的 /data/db 目录，作为 mongo 数据的存储目录

进入创建的 mongo 目录，创建 Dockerfile

# add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added

EXPOSE 27017

通过Dockerfile创建一个镜像，替换成你自己的名字：

docker build -t mongo:3.2 .

使用mongo镜像

运行镜像，生成容器

使用 docker run 命令运行镜像 mongo:3.2：

docker run --name my-mongo -p 27017:27017 -v $PWD/db:/data/db -d mongo:3.2

命令说明：

-p 27017:27017 :将主机的27017 端口映射到容器的27017 端口

-v $PWD/db:/data/db :将主机中当前目录下的db挂载到容器的/data/db，作为mongo数据存储目录

查看容器的运行情况：

docker ps

使用 docker exec 命令访问容器 my-mongo：

docker exec -it my-mongo /bin/bash
mongo status
mongo
show dbs;

使用 docker run 命令运行镜像 mongo:latest：

docker run --name my-mongo-latest -p 27017:27017 -v $PWD/db:/data/db -d mongo:latest

使用 docker exec 命令访问容器 my-mongo-latest：

docker exec -it my-mongo-latest /bin/bash
mongo status
show dbs;

目前 Docker Hub 上 mongo:latest 对应的 版本是 4.0.10
