Docker 安装 MongoDB

方法一、docker pull mongo

查找Docker Hub上的mongo镜像

codercto@codercto:~/mongo$ docker search mongo

这里我们拉取官方的镜像,标签为3.2

codercto@codercto:~/mongo$ docker pull mongo

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。

codercto@codercto:~/mongo$ docker images mongo
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
mongo               latest              63c6b736e399        2 days ago          379MB

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。

codercto@codercto:~$ 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

FROM debian:jessie-slim

# add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added
RUN groupadd -r mongodb && useradd -r -g mongodb mongodb

ENV MONGO_PACKAGE=${MONGO_PACKAGE} MONGO_REPO=${MONGO_REPO}

RUN ln -s usr/local/bin/docker-entrypoint.sh /entrypoint.sh # backwards compat
ENTRYPOINT ["docker-entrypoint.sh"]

EXPOSE 27017
CMD ["mongod"]

通过Dockerfile创建一个镜像，替换成你自己的名字

codercto@codercto:~/mongo$ docker build -t mongo:3.2 .

创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像

codercto@codercto:~/mongo$ docker images  mongo:3.2
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
mongo               3.2                 282fd552add6        9 days ago          336.1 MB

使用mongo镜像

运行容器

codercto@codercto:~/mongo$ docker run -p 27017:27017 -v $PWD/db:/data/db -d mongo:3.2
cda8830cad5fe35e9c4aed037bbd5434b69b19bf2075c8626911e6ebb08cad51
codercto@codercto:~/mongo$

命令说明：

-p 27017:27017 :将容器的27017 端口映射到主机的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

查看容器启动情况

codercto@codercto:~/mongo$ docker ps 
CONTAINER ID   IMAGE        COMMAND                   ...    PORTS                      NAMES
cda8830cad5f   mongo:3.2    "/entrypoint.sh mongo"    ...    0.0.0.0:27017->27017/tcp   suspicious_goodall

使用mongo镜像执行mongo 命令连接到刚启动的容器,主机IP为172.17.0.1

codercto@codercto:~/mongo$ docker run -it mongo:3.2 mongo --host 172.17.0.1
MongoDB shell version: 3.2.7
connecting to: 172.17.0.1:27017/test
Welcome to the MongoDB shell.
