搭建docker registry私有镜像仓库

搭建docker registry私有镜像仓库

一、安装docker-distribution

yum install -y docker-distribution

安装完成后,启动服务:

systemctl enable docker-distribution.service

systemctl start docker-distribution.service

二、配置config.yaml

在/etc/docker-distribution/registry目录下编辑config.yaml文件如下:

[root@k8s-master docker]# vim /etc/docker-distribution/registry/config.yml

version: 0.1

log:

fields:

service: registry

storage:

cache:

layerinfo: inmemory

filesystem:

rootdirectory: /var/lib/registry #可修改

http:

addr: 192.168.60.128:5000 # [仓库运行的IP地址]:[仓库运行的端口,可设为5000]

三、修改daemon.json

[root@k8s-master docker]# vim /etc/docker/daemon.json

{"insecure-registries": ["192.168.60.128:5000"]}

随后重启docker:

systemctl restart docker

这样就完成了私有仓库的搭建。

四、测试上传

用docker images查看已下载的镜像,选择一个,例如tomcat,打上标签:

docker tag [tomcat镜像的ID] [仓库IP]:[仓库端口]/tomcat

docker tag 29a4ec4a1572 192.168.60.128:5000/tomcat

之后,用docker push命令将打上标签后的镜像上传至私有仓库:

docker push [仓库IP]:[仓库端口]/tomcat

docker push 192.168.60.128:5000/tomcat

看到类似于下面这样的提示后,说明上传成功:

[root@k8s-master docker]# docker push 192.168.60.128:5000/tomcat

The push refers to a repository [192.168.60.128:5000/tomcat]

五、测试查询

Docker registry v2的API与v1差异非常大。例如,用下面的命令查看已上传的镜像:

curl -X GET http://仓库IP:仓库端口/v2/_catalog

[root@k8s-master docker]# curl -X GET http://192.168.60.128:5000/v2/_catalog

{"repositories":["tomcat"]}
