篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Docker安装和使用相关的知识，希望对你有一定的参考价值。
一，安装Docker
1.1 安装之前保持一个干净的Docker环境
sudo yum remove docker docker-common docker-selinux docker-engine
1.2 安装一些依赖
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
1.3 下载repo文件
wget -O /etc/yum.repos.d/docker-ce.repo https://download.docker.com/linux/centos/docker-ce.repo
1.4 把软件仓管地址替换为 TUNA
sudo sed -i \'s+download.docker.com+mirrors.tuna.tsinghua.edu.cn/docker-ce+\' /etc/yum.repos.d/docker-ce.repo
1.5 安装
sudo yum makecache fast sudo yum install docker-ce
参考文档：https://mirrors.tuna.tsinghua.edu.cn/help/docker-ce/
1.6 安装完成后可以使用：dock version 命令查看docker信息
[root@linux-node1 ~]# Client: Version: 17.09.0-ce API version: 1.32 Go version: go1.8.3 Git commit: afdb6d4 Built: Tue Sep 26 22:41:23 2017 OS/Arch: linux/amd64 Server: Version: 17.09.0-ce API version: 1.32 (minimum version 1.12) Go version: go1.8.3 Git commit: afdb6d4 Built: Tue Sep 26 22:42:49 2017 OS/Arch: linux/amd64 Experimental: false
二，安装docker-compose
2.1 先确认完成docker环境安装，再执行此步骤
2.2 参考文档：
https://docs.docker.com/compose/install/
2.3 以CentOS为例：
2.3.1下载docker compose执行文件
sudo curl -L https://github.com/docker/compose/releases/download/1.17.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
2.3.2 添加执行权限
sudo chmod +x /usr/local/bin/docker-compose
2.3.3 验证结果
docker-compose --version docker-compose version 1.17.0, build 1719ceb
三，下载镜像文件
3.1 配置国内Docker镜像加速，国内拉取官方docker镜像速度较慢
[root@linux-node1 data]# more /etc/docker/daemon.json
{"registry-mirrors": ["http://4c7d9402.m.daocloud.io"]}
3.2 下载Docker的Cent0S镜像
[root@linux-node1 ~]# docker pull centos Using default tag: latest latest: Pulling from library/centos d9aaf4d82f24: Pull complete Digest: sha256:4565fe2dd7f4770e825d4bd9c761a81b26e49cc9e3c9631c58cfc3188be9505a Status: Downloaded newer image for centos:latest
3.3 查看镜像
[root@linux-node1 ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE centos latest d123f4e55e12 3 weeks ago 197MB
3.4 根据一个镜像可以启动多个容器，启动容器的命令是docker run
[root@linux-node1 ~]# docker run -i -t centos /bin/bash [root@0ac90dce2eee /]#
-t 表示让Docker分配一个伪终端并绑定到容器的标准输入上
-i 表示让容器的标准输入保持打开
-d 表示以守护方式打开（即非交互模式，后台运行）
还有一个比较常用的，做网络配置时端口映射的参数-p，例如下面的命令将宿主机的3222端口映射到容器的22端口、将宿主机的3280端口映射到容器的80端口，用法如下：
#-p 设置端口映射 -p 宿主机端口:容器端口 docker run -t -i -p 3222:22 -p 3280:80 87e5b6b3ccc1 /bin/bash
3.5 搜索镜像，比如搜索一个redis的镜像，STARS 越多说明越好
[root@linux-node1 ~]# docker search redis NAME DESCRIPTION STARS OFFICIAL AUTOMATED redis Redis is an open source key-value store th... 4483 [OK] bitnami/redis Bitnami Redis Docker Image 61 [OK] sameersbn/redis 59 [OK] tenstartups/redis-commander 31 [OK] joshula/redis-sentinel A container for Redis Sentinel 19 kubeguide/redis-master redis-master with "Hello World!" 19 kubeguide/guestbook-redis-slave Guestbook redis slave 15 tutum/redis Base docker image to run a Redis server 10 webhippie/redis Docker images for redis 7 [OK] rtoma/logspout-redis-logstash Logspout including Redis adapter for sendi... 5 gurpartap/redis Smallest redis image at 18.56MB, 5.6MB of ... 3 arm32v7/redis Redis is an open source key-value store th... 3 centos/redis-32-centos7 Redis in-memory data structure store, used... 2 tomesar/redis-arm Redis for ARM! 2 [OK] google/guestbook-python-redis A simple guestbook example written in Pyth... 1 frodenas/redis A Docker Image for Redis 1 [OK] dynomitedb/redis Redis backend for DynomiteDB. 1 [OK] vidazoohub/marathon-redis-autoscale autoscale worker tasks based on redis size 1 [OK] sstarcher/fluent-redis-aws https://github.com/sstarcher/docker-fluent... 0 [OK] brendangibat/docker-logspout-redis Docker Logspout container with Logspout-Re... 0 [OK] anchorfree/redis redis cache server for logging 0 kilsoo75/redis-master This image is for the redis master of SK C... 0 iadvize/redis 0 rediscommander/redis-commander Alpine image for redis-commander - Redis m... 0 [OK] ajmath/fluentd-redis Use fluentd logs to send docker logs to re... 0 [OK]
3.5 查看及删除镜像
docker images： # 列出images docker images -a # 列出所有的images（包含历史） docker rmi <image ID>： # 删除一个或多个image
3.6 查看容器
docker ps ：列出当前所有正在运行的container docker ps -l ：列出最近一次启动的container docker ps -a ：列出所有的container（包含历史，即运行过的container） docker ps -q ：列出最近一次运行的container ID
3.7 重启容器等操作
docker start/stop/restart <container> #：开启/停止/重启container docker start [container_id] #：再次运行某个container （包括历史container） docker attach [container_id] #：连接一个正在运行的container实例（即实例须为start状态，可以多个窗口同时attach 一个container实例） docker start -i <container> #：启动一个container并进入交互模式（相当于先start，在attach） docker run -i -t <image> /bin/bash #：使用image创建container并进入交互模式, login shell是/bin/bash docker run -i -t -p <host_port:contain_port> #：映射 HOST 端口到容器，方便外部访问容器内服务，host_port 可以省略，省略表示把 container_port 映射到一个动态端口。 #注：使用start是启动已经创建过得container，使用run则通过image开启一个新的 container。
3.8 删除容器
docker rm <container...> #：删除一个或多个container docker rm `docker ps -a -q` #：删除所有的container docker ps -a -q | xargs docker rm #：同上, 删除所有的container
四，Docker镜像文件导入导出
4.1 查看镜像id
[root@linux-node1 ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE sonarqube latest c1637bd4502f 12 days ago 934MB jenkins latest 3f08dc4f3f5d 3 weeks ago 809MB centos latest d123f4e55e12 3 weeks ago 197MB
4.2 选择要打包的镜像，执行打包命令
#方法一 [root@linux-node1 ~]# docker save -o centos.tar centos #镜像名称 [root@linux-node1 ~]# ls anaconda-ks.cfg centos.tar #方法二 确切的说，export其实是容器的保存，只把镜像当前的状态保存下来 [root@linux-node1 ~]# docker export -o centos-1.tar b2be6c76c9e2 #容器id
会在当前目录下生成导出文件xxx.tar，然后将此文件下载到本地
4.3 导入上述打包的镜像
五，使用Docker Compose管理多个容器
Docker Compose是一个用来定义和运行复杂应用的Docker工具。使用Compose，你可以在一个文件中定义一个多容器应用，然后使用一条命令来启动你的应用，完成一切准备工作。
- github.com/docker/compose
5.1 一个使用Docker容器的应用，通常由多个容器组成。使用Docker Compose，不再需要使用shell脚本来启动容器。在配置文件中，所有的容器通过services来定义，然后使用docker-compose脚本来启动，停止和重启应用，和应用中的服务以及所有依赖服务的容器。完整的命令列表如下：
build 构建或重建服务 help 命令帮助 kill 杀掉容器 logs 显示容器的输出内容 port 打印绑定的开放端口 ps 显示容器 pull 拉取服务镜像 restart 重启服务 rm 删除停止的容器 run 运行一个一次性命令 scale 设置服务的容器数目 start 开启服务 stop 停止服务 up 创建并启动容器
参考 https://docs.docker.com/compose/install/ 。你能运行Compose在OSX和64位Linux
5.2 在上面2.1步骤中我们已经安装了 Doceker Compose
curl -L https://github.com/docker/compose/releases/download/1.4.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose chmod x /usr/local/bin/docker-compose
5.3 Compose的配置文件是docker-compose.yml。让我们看看下面这个文件：
[root@linux-node1 devops]# cat docker-compose.yml version: \'2\' services: gitlab: image: gitlab/gitlab-ce:latest ports: - "443:443" - "80:80" - "22:22" networks: - devops volumes: - /root/data/gitlab/config:/etc/gitlab - /root/data/gitlab/logs:/var/log/gitlab - /root/data/gitlab/data:/var/opt/gitlab jenkins: image: jenkins:latest ports: - "8080:8080" - "50000:50000" networks: - devops volumes: - /root/data/jenkins:/var/jenkins_home - /var/run/docker.sock:/var/run/docker.sock sonarqube: image: sonarqube:latest ports: - "9000:9000" - "9092:9092" networks: - devops networks: devops: driver: bridge
a. 定义了两个服务分别叫做gitlab，jenkins和sonarqube
b. 使用image定义每个服务的镜像名
c. networks:定义网络类型
d. volumes：定义卷与本地磁盘的映射关系
e. 使用ports实现端口转发
5.4 启动服务
docker-compose.yml是compose默认查找的文件，使用下面的命令，所有的服务将使用后台模式被启动
使用-f指定代替的compose文件
使用-p指定代替compose文件所在的目录
docker-compose up -d jenkins #也可以指定 docker-compose.yml中某一个服务运行
5.5 验证启动的服务
这里提供了一个整合的列表显示所有启动的服务和容器
5.6 通常使用docker ps命令来验证应用的容器，和在Docker主机上运行的其他容器
5.7 停止服务
5.8 查看日志
