Docke部署本地私有镜像仓库_docke 修改镜像地址

使用目前最新版Docker13.1搭建私有镜像仓库

安装Docker

安装最新版Docker sudo yum install -y docker

查看docker版本信息

$ sudo docker version

下载docker registry私有镜像

docker pull docker.io/registry

修改docker配置文件

修改配置文件 sudo vi /etc/sysconfig/docker
OPTIONS=’–selinux-enabled –log-driver=journald –signature-verification=false –insecure-registry 127.0.0.1:5000‘加粗地方是要加入的，是需要加入认证许可。

从容器中启动registry

1. 创建本地文件目录：sudo mkdir /usr/local/src/docker_image_repo
2. 启动命令：sudo docker run -d -p 5000:5000 --name registry-local -v /usr/local/src/docker_image_repo:/tmp/registry docker.io/registry
   将容器的5000端口映射到本地机器的5000端口，将容器内的/tmp/registry指向容器外部路径/usr/local/src/docker_image_repo

查看docker镜像并打标签

• 通过命令sudo docker images得到镜像列表

$ sudo docker images
REPOSITORY                   TAG                 IMAGE ID            CREATED             SIZE
learn/ping                   latest              f4c5a1866235        4 hours ago         140 MB
docker.io/hello-world        latest              e38bc07ac18e        2 months ago        1.85 kB
docker.io/registry           latest              d1fd7d86a825        5 months ago        33.3 MB
docker.io/learn/tutorial     latest              a7876479f1aa        5 years ago         128 MB

• 通过tag命令打标签
  将镜像列表的docker.io/registry标记为127.0.0.1:5000/registry
  docker tag docker.io/registry:latest 127.0.0.1:5000/registry

上传标签镜像到私有云

只能将tag标签设置为127.0.0.1:5000的镜像上传到私有镜像库，上传命令：
sudo docker push 127.0.0.1:5000/registry

查看私有镜像仓库列表

$ curl -XGET http://127.0.0.1:5000/v2/_catalog
{"repositories":["hello-world","learn/ping","registry"]}
