Centos7.4搭建docker_1.13.1私有仓库

1、配置docker的国内加速器

docker版本为1.13.1需要配置一下daemon.json

配置阿里云的docker加速器：

nielinqi@Centos:~$   vim  /etc/docker/daemon .json
{
   "registry-mirrors" : [
      "https://kv3qfp85.mirror.aliyuncs.com"
    ]
}

2、拉取registry仓库docker镜像

nielinqi@Centos:~$   docker pull registry

3、创建registry docker进程

nielinqi@Centos:~$   docker run -d --privileged -p 5000:5000 --name registry --restart=always -v /myregistry:/var/lib/registry registry ry : /var/lib/registry  registry
nielinqi@Centos:~$  sudo  docker  ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
d8f77abe36a7        registry             "/entrypoint.sh /e..."    2 hours ago         Up 2 hours          0.0.0.0:5000->5000 /tcp    registry

4、测试上传一个镜像

下载一个测试镜像

nielinqi@Centos:~$  sudo  docker pull busybox

将busybox镜像重命名为本地镜像格式与本地registry相匹配。

镜像名称由registry和tag两部分组成，registry完整格式：[registry_ip]:[registry:port]/[user]/[image_name:version]

nielinqi@Centos:~$  sudo  docker tag busybox 192.168.56.101:5000 /nielinqi/test :v1.0

5、使用docker push命令上传镜像

nielinqi@Centos:~$  sudo  docker push 192.168.56.101:5000 /nielinqi/test :v1.0

查看镜像

nielinqi@Centos:~$ curl http: //192 .168.56.101:5000 /v2/_catalog
{ "repositories" :[ "nielinqi/my-image" , "nielinqi/test" ]}

在此需要配置daemon.json的insecure-registries，为了解决https的报错，因为docker默认使用https协议，但是本地现在只支持http协议

不配置daemon.json的话会出现一下错误：

Get https: //192 .168.56.101:5000 /v1/_ping : http: server gave HTTP response to HTTPS clie

配置如下：

nielinqi@Centos:~$  sudo  vim  /etc/docker/daemon .json
{
   "registry-mirrors" : [
      "https://kv3qfp85.mirror.aliyuncs.com"
   ],
   "insecure-registries" : [
      "192.168.56.101:5000"
    ]
}

重启docker进程

nielinqi@Centos:~$  sudo  systemctl restart docker

上传报错的问题就此解决

6、下载镜像测试一下

nielinqi@Centos:~$  sudo  docker pull 192.168.56.101:5000 /wangpeng/test :v1.0
v1.0: Pulling from wangpeng /test
Digest: sha256:73a74253ed45caebc619d95b1d84e4d67a64e5b6d81e31ac7c496b9c11128d74
Status: Image is up to  date  for  192.168.56.101:5000 /wangpeng/test :v1.0
