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。

  1. 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

  1. FROM debian:wheezy# add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get addedRUN groupadd -r mongodb && useradd -r -g mongodb mongodb
  3. RUN apt-get update \    && apt-get install -y --no-install-recommends \
  4.         numactl \    && rm -rf /var/lib/apt/lists/*
  6. # grab gosu for easy step-down from root
  7. ENV GOSU_VERSION 1.7
  8. RUN set -x \
  9.     && apt-get update && apt-get install -y --no-install-recommends ca-certificates wget && rm -rf /var/lib/apt/lists/* \
  10.     && wget -O /usr/local/bin/gosu "https://github.com/tianon/gosu/releases/download/$GOSU_VERSION/gosu-$(dpkg --print-architecture)" \
  11.     && wget -O /usr/local/bin/gosu.asc "https://github.com/tianon/gosu/releases/download/$GOSU_VERSION/gosu-$(dpkg --print-architecture).asc" \
  12.     && export GNUPGHOME="$(mktemp -d)" \
  13.     && gpg --keyserver ha.pool.sks-keyservers.net --recv-keys B42F6819007F00F88E364FD4036A9C25BF357DD4 \
  14.     && gpg --batch --verify /usr/local/bin/gosu.asc /usr/local/bin/gosu \
  15.     && rm -r "$GNUPGHOME" /usr/local/bin/gosu.asc \
  16.     && chmod +x /usr/local/bin/gosu \
  17.     && gosu nobody true \
  18.     && apt-get purge -y --auto-remove ca-certificates wget
  20. # gpg: key 7F0CEB10: public key "Richard Kreuter <richard@10gen.com>" imported
  21. RUN apt-key adv --keyserver ha.pool.sks-keyservers.net --recv-keys 492EAFE8CD016A07919F1D2B9ECBEC467F0CEB10
  23. ENV MONGO_MAJOR 3.0
  24. ENV MONGO_VERSION 3.0.12
  26. ENV MONGO_MAJOR 3.0
  27. ENV MONGO_VERSION 3.0.12
  29. RUN echo "deb http://repo.mongodb.org/apt/debian wheezy/mongodb-org/$MONGO_MAJOR main" > /etc/apt/sources.list.d/mongodb-org.list
  31. RUN set -x \
  32.     && apt-get update \
  33.     && apt-get install -y \
  34.         mongodb-org=$MONGO_VERSION \
  35.         mongodb-org-server=$MONGO_VERSION \
  36.         mongodb-org-shell=$MONGO_VERSION \
  37.         mongodb-org-mongos=$MONGO_VERSION \
  38.         mongodb-org-tools=$MONGO_VERSION \
  39.     && rm -rf /var/lib/apt/lists/* \
  40.     && rm -rf /var/lib/mongodb \
  41.     && mv /etc/mongod.conf /etc/mongod.conf.orig
  43. RUN mkdir -p /data/db /data/configdb \
  44.     && chown -R mongodb:mongodb /data/db /data/configdb
  45. VOLUME /data/db /data/configdb
  47. COPY docker-entrypoint.sh /entrypoint.sh
  48. ENTRYPOINT ["/entrypoint.sh"]
  50. EXPOSE 27017
  51. CMD ["mongod"]

通过Dockerfile 创建一个镜像，替换成自己的名字

  1. docker build -t mongo:3.2 .

创建完成后，可在本地的镜像列表中查找到刚刚创建的镜像

  1. docker images mongo:3.2

方法二、docker pull mogo:3.2

查找Docker Hub上的mongo镜像

  1. docker search mongo

这里拉取官方的镜像，标签为3.2 

  1. docker pull mongo:3.2

使用mongo镜像

运行容器

  1. docker run -p 27017:27017 -v $PWD/db:/data/db -d mongo:3.2

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

  1. docker ps

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

  1. docker run -it mongo:3.2 mongo --host 172.17.0.1
