Docker 安装 MongoDB

方法一、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。

runoob@runoob:~$ 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:wheezy

# 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

RUN apt-get update \
	&& apt-get install -y --no-install-recommends \
		numactl \
	&& rm -rf /var/lib/apt/lists/*

# grab gosu for easy step-down from root
ENV GOSU_VERSION 1.7
RUN set -x \
	&& apt-get update && apt-get install -y --no-install-recommends ca-certificates wget && rm -rf /var/lib/apt/lists/* \
	&& wget -O /usr/local/bin/gosu "https://github.com/tianon/gosu/releases/download/$GOSU_VERSION/gosu-$(dpkg --print-architecture)" \
	&& wget -O /usr/local/bin/gosu.asc "https://github.com/tianon/gosu/releases/download/$GOSU_VERSION/gosu-$(dpkg --print-architecture).asc" \
	&& export GNUPGHOME="$(mktemp -d)" \
	&& gpg --keyserver ha.pool.sks-keyservers.net --recv-keys B42F6819007F00F88E364FD4036A9C25BF357DD4 \
	&& gpg --batch --verify /usr/local/bin/gosu.asc /usr/local/bin/gosu \
	&& rm -r "$GNUPGHOME" /usr/local/bin/gosu.asc \
	&& chmod +x /usr/local/bin/gosu \
	&& gosu nobody true \
	&& apt-get purge -y --auto-remove ca-certificates wget

# gpg: key 7F0CEB10: public key "Richard Kreuter <richard@10gen.com>" imported
RUN apt-key adv --keyserver ha.pool.sks-keyservers.net --recv-keys 492EAFE8CD016A07919F1D2B9ECBEC467F0CEB10

ENV MONGO_MAJOR 3.0
ENV MONGO_VERSION 3.0.12

RUN echo "deb http://repo.mongodb.org/apt/debian wheezy/mongodb-org/$MONGO_MAJOR main" > /etc/apt/sources.list.d/mongodb-org.list

RUN set -x \
	&& apt-get update \
	&& apt-get install -y \
		mongodb-org=$MONGO_VERSION \
		mongodb-org-server=$MONGO_VERSION \
		mongodb-org-shell=$MONGO_VERSION \
		mongodb-org-mongos=$MONGO_VERSION \
		mongodb-org-tools=$MONGO_VERSION \
	&& rm -rf /var/lib/apt/lists/* \
	&& rm -rf /var/lib/mongodb \
	&& mv /etc/mongod.conf /etc/mongod.conf.orig

RUN mkdir -p /data/db /data/configdb \
	&& chown -R mongodb:mongodb /data/db /data/configdb
VOLUME /data/db /data/configdb

COPY docker-entrypoint.sh /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]

EXPOSE 27017
CMD ["mongod"]

通过Dockerfile创建一个镜像，替换成你自己的名字

runoob@runoob:~/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

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

方法二、docker pull mongo:3.2

查找Docker Hub上的mongo镜像

runoob@runoob:~/mongo$ docker search mongo

这里我们拉取官方的镜像,标签为3.2

runoob@runoob:~/mongo$ 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。

使用mongo镜像

运行容器

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

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

runoob@runoob:~/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

runoob@runoob:~/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
