【原创】运维基础之Docker（3）搭建私有仓库

 

下载并启动registry

$ docker pull registry
$ docker run --name my_registry -d -p 5000:5000 -v /var/lib/registry:/var/lib/registry registry

从官方仓库下载nginx并push到私有仓库中

$ docker pull nginx
$ docker tag nginx localhost:5000/mynginx
$ docker push localhost:5000/mynginx

push报错

The push refers to repository [localhost:5000/nginx]
Get https://localhost:5000/v2/: http: server gave HTTP response to HTTPS client

解决方法

$ echo '{ "insecure-registries":["localhost:5000"] }' > /etc/docker/daemon.json
$ service docker restart

早期docker版本（1.10及以前）不支持insecure-registries，须要改成

# vi /etc/sysconfig/docker
OPTIONS='--selinux-enabled --insecure-registry=localhost:5000 --log-driver=journald'

再push便可

$ curl http://localhost:5000/v2/_catalog{"repositories":["mynginx"]}
