一直学一直嗨,一直嗨一直学

在Linux系统上部署docker私有仓库

修改配置http访问
  [root@test01 ~]# cat /etc/docker/daemon.json  {"registry-mirrors": ["https://registry.docker-cn.com"],"insecure-registries":["192.168.1.30:5000"]}  

如果不这样配置,结果如下。这个问题可能是由于客户端采用https,docker registry未采用https服务所致。一种处理方式是把客户对地址“192.168.1.30:5000”请求改为http

  [root@test01 ~]# docker push 192.168.1.30:5000/centos  The push refers to a repository [192.168.1.30:5000/centos]  Get https://192.168.1.30:5000/v1/_ping: http: server gave HTTP response to HTTPS client  
使用容器运行docker-registry
  [root@test01 ~]# docker run -d -p 5000:5000 --privileged=true -v /opt/data/registry:/tmp/registry --name='docker-registry' registry  

参数说明:

  -v /opt/data/registry:/tmp/registry :默认情况下,会将仓库存放于容器内的/tmp/registry目录下,指定本地目录挂载到容器  –privileged=true :CentOS7中的安全模块selinux把权限禁掉了,参数给容器加特权,不加上传镜像会报权限错误(OSError: [Errno 13] Permission denied: ‘/tmp/registry/repositories/liibrary’)或者(Received unexpected HTTP status: 500 Internal Server Error)错误  
上传镜像
  [root@test01 ~]# docker images  REPOSITORY                 TAG                 IMAGE ID            CREATED             SIZE  docker.io/wordpress        latest              346b1443b020        30 hours ago        407 MB  [root@test01 ~]# docker push 192.168.1.30:5000/wordpress  The push refers to a repository [192.168.1.30:5000/wordpress]  An image does not exist locally with the tag: 192.168.1.30:5000/wordpress  [root@test01 ~]#  

根据提示,我们知道需要修改一下tag才能上传

  [root@test01 ~]# docker tag docker.io/wordpress 192.168.1.30:5000/wordpress  [root@test01 ~]# docker images  REPOSITORY                    TAG                 IMAGE ID            CREATED             SIZE  192.168.1.30:5000/wordpress   latest              346b1443b020        30 hours ago        407 MB  docker.io/wordpress           latest              346b1443b020        30 hours ago        407 MB  [root@test01 ~]# docker push 192.168.1.30:5000/wordpress  The push refers to a repository [192.168.1.30:5000/wordpress]  3d7c1bb6ce9f: Pushed  
从私有仓库中下载
  [root@test01 ~]# docker pull 192.168.1.30:5000/wordpress  
客户端永久配置使用私有仓库
  加入ADD_REGISTRY='--add-registry 192.168.1.30:5000'    [root@test01 ~]# cat /etc/sysconfig/docker  # /etc/sysconfig/docker    # Modify these options if you want to change the way the docker daemon runs  OPTIONS='--selinux-enabled --log-driver=journald --signature-verification=false -H unix:///var/run/docker.sock -H 0.0.0.0:2376'  ADD_REGISTRY='--add-registry 192.168.1.30:5000'  if [ -z "${DOCKER_CERT_PATH}" ]; then      DOCKER_CERT_PATH=/etc/docker  fi
