第五章:访问Docker仓库第五章:访问Docker仓库

5.1Docker Hub 公共镜像市场 1.登录

$ docker login# 登录

2.基本操作
搜寻镜像

$ docker search centos NAMEDESCRIPTIONSTARSOFFICIALAUTOMATED centosThe official build of CentOS.3540[OK] jdeathe/centos-sshCentOS-6 6.9 x86_64 / CentOS-7 7.3.1611 x8...79[OK] tutum/centosSimple CentOS docker image with SSH access33 ......

pull镜像

$ docker pull centos Using default tag: latest latest: Pulling from library/centos 7b6bb4652a1b: Pull complete Digest: sha256:c1010e2fe2b635822d99a096b1f4184becf5d1c98707cbccae00be663a9b9131 Status: Downloaded newer image for centos:latest

【第五章:访问Docker仓库】用户还可以在登录后通过 docker push命令将本地镜像推送到Docker Hub。

$ docker login# 登录 Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one. Username: xrichardyan Password: Login Succeeded $ docker tag centos:latest xrichardyan/centos:1.0# 先添加新的标签 username/centos:1.0username必须是Docker Hub的username. $ docker push xrichardyan/centos:1.0# push成功 The push refers to a repository [docker.io/xrichardyan/centos] 99b28d9413e4: Mounted from library/centos 1.0: digest: sha256:c1010e2fe2b635822d99a096b1f4184becf5d1c98707cbccae00be663a9b9131 size: 529

3.自动创建
5.2时速云镜像市场其中同步了所有Docker Hub的镜头,通过这个下载镜像会很快。
5.3搭建本地私有仓库 1.使用registry镜像创建私有仓库

$ docker run -d -p 5000:5000 registry Unable to find image 'registry:latest' locally latest: Pulling from library/registry 90f4dba627d6: Pull complete 3a754cdc94a5: Pull complete bf16d9b6d4c1: Pull complete 7eea83c9b7bb: Pull complete 23293c727551: Pull complete Digest: sha256:295b693558f0bcc6dc389229b87bcce5d3385357086d444dd317435d8b2810c1 Status: Downloaded newer image for registry:latest 09701b529bf3e4240cdb03e23a6f7b740f0129bda243ec3dd38f61582fd44512

这将自动下载并启动一个registry容器，创建本地的私有仓库服务。
默认情况下，会将仓库创建在容器的/特么/registry目录下。也可以通过 -v 参数来讲镜像文件存放在本地指定的路径。
例如下面的例子讲上传的镜像放在/opt/data/registry 目录：
