      Docker 安装 MongoDB

      Docker 安装 MongoDB

      方法一、docker pull mongo

      查找 Docker Hub 上的 mongo 镜像

      axihe@axihe:~/mongo$ docker search mongo

      这里我们拉取官方的镜像,标签为 3.2

      axihe@axihe:~/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。

      axihe@axihe:~/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。

      axihe@axihe:~$ 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

      RUN groupadd -r mongodb && useradd -r -g mongodb mongodb

      RUN set -ex; \

          wget -O /usr/local/bin/gosu.asc "https://github.com/tianon/gosu/releases/download/$GOSU_VERSION/gosu-$dpkgArch.asc"; \

          wget -O /js-yaml.js "https://github.com/nodeca/js-yaml/raw/${JSYAML_VERSION}/dist/js-yaml.js"; \
      # TODO some sort of download verification here
          \
          apt-get purge -y --auto-remove wget
      
      RUN mkdir /docker-entrypoint-initdb.d
      
      ENV GPG_KEYS \

      RUN set -ex; \
          export GNUPGHOME="$(mktemp -d)"; \
          for key in $GPG_KEYS; do \

          done; \

          rm -r "$GNUPGHOME"; \
          apt-key list
      
      # Allow build-time overrides (eg. to build image with MongoDB Enterprise version)
      # Options for MONGO_PACKAGE: mongodb-org OR mongodb-enterprise
      # Options for MONGO_REPO: repo.mongodb.org OR repo.mongodb.com
      # Example: docker build --build-arg MONGO_PACKAGE=mongodb-enterprise --build-arg MONGO_REPO=repo.mongodb.com .

          && 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 /usr/local/bin/
      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

      axihe@axihe:~/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

      axihe@axihe:~/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

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

      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

      axihe@axihe:~/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

      axihe@axihe:~/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
