Docker 之 阿里云镜像

前言

本小节我们将学习一下使用阿里云容器镜像服务来管理我们的镜像。

• Docker 环境准备（已安装的可省略此步骤）

  docker version > /dev/null || curl -fsSL get.docker.com | bash 
  service docker restart 
  systemctl enable docker  #设置开机自启
  

• 使用阿里云容器镜像服务并创建自己的镜像仓库：

  • 创建你的命名空间：名为dustyone
    
  • 假设你的阿里云登录账号为123456789
  • 假设你创建的镜像仓库：名为dustyone_repository
    https://cr.console.aliyun.com/cn-shenzhen/instances/repositories
    

• 设置镜像仓库访问授权，以方便通过Docker CTL 登录并访问我们的阿里云镜像仓库

此处我们设置访问凭证，建议为固定的凭证，假设你设置的固定凭证abcde

• Docker Login
  使用如下命令登录：

  sudo docker login --username=123456789 --password=abcde registry.cn-shenzhen.aliyuncs.com
  

  其中‘123456789 ’为你的阿里云登录账号，abcde为镜像仓库的访问凭证

• Docker镜像PUSH操作

  • 查看本地镜像：假设本地有个如下镜像

    [root@iZwz92qakfc7zvdr9h0gipZ kodexplorer]# docker images
    REPOSITORY                          TAG                 IMAGE ID            CREATED             SIZE
    docker.io/baiyuetribe/kodexplorer   latest              cc7aef62c0b1        7 weeks ago         102 MB
    [root@iZwz92qakfc7zvdr9h0gipZ kodexplorer]# 
    
    

  • 给指定的镜像打Tag

    sudo docker tag cc7aef62c0b1 registry.cn-shenzhen.aliyuncs.com/dustyone/dustyone_repository:kodExplorer-latest
    

  • 查看镜像信息

    [root@iZwz92qakfc7zvdr9h0gipZ kodexplorer]# sudo docker tag cc7aef62c0b1 registry.cn-shenzhen.aliyuncs.com/dustyone/dustyone_repository:kodExplorer-latest
    [root@iZwz92qakfc7zvdr9h0gipZ kodexplorer]# docker images
    REPOSITORY                                                       TAG                  IMAGE ID            CREATED             SIZE
    registry.cn-shenzhen.aliyuncs.com/dustyone/dustyone_repository   kodExplorer-latest   cc7aef62c0b1        7 weeks ago         102 MB
    docker.io/baiyuetribe/kodexplorer                                latest               cc7aef62c0b1        7 weeks ago         102 MB
    
    

  • 将镜像push到阿里云镜像服务上去

    sudo docker push registry.cn-shenzhen.aliyuncs.com/dustyone/dustyone_repository:kodExplorer-latest
    

    kodExplorer-latest: digest: sha256:58983b0e28a73394d73a23efe61431945bcfdfae2319222f9e18fe72276eaf99 size: 3456
    [root@iZwz92qakfc7zvdr9h0gipZ kodexplorer]# 
    
    

    

• Docker镜像PULL操作
  如上所示我们已经成功把我们本地的镜像推到了阿里云镜像服务指定的仓库中去了，下面我们将模拟从阿里云镜像服务指定的镜像仓库中拉去镜像并运行镜像

  • 清除所有镜像(建议你谨慎执行此操作，如不需要建议不要操作此步骤)

    [root@iZwz92qakfc7zvdr9h0gipZ kodexplorer]# docker rmi -f cc7aef62c0b1

  • 运行镜像

    docker run -d -p 8088:80 --name kodexplorer -v "$PWD":/code cc7aef62c0b1
    

    -d容器后台运行，-p指定运行端口，-name 镜像在容器中的名字， -v "$PWD":/code容器运行挂在的文件路径，其中"$PWD"表示当前路径，cc7aef62c0b1 镜像ID

  如上便表示kodexplorer镜像已运行了

• 检验
  

  • 如上使用的案例所运行的Docker容器在我的云服务器上，因而输入：http://公网IP:8088/index.php?user/login 或者
    http://公网IP：8088即可。
  • 若使用阿里云服务器运行Docker容器，请提前设置安全组规则，即给所需服务开端口。
