  1. registry的安装

关于docker registry的安装,可以说简单的不能再简单了,docker run一个容器就好了,也就是一条命令的事

docker run -d -p 5000:5000 --restart=always --name registry -v /opt/myregistry:/var/lib/registry registry

 

  1. 上传镜像

上次镜像其实就两步,给镜像打tag和push上传

  1. 打tag

格式:docker tag 源镜像名字:版本 私有仓库地址/镜像名字:版本

例如:

docker tag centos:6.10 10.0.0.11:5000/centos:6.10

  1. push上传

docker push 10.0.0.11:5000/centos:6.10

默认上传肯定报错!

The push refers to a repository [10.0.0.11:5000/centos:6.10]

Get https://10.0.0.11:5000/v1/_ping: http: server gave HTTP response to HTTPS client

解决办法:

把自己的私有镜像仓库加到信任的仓库列表中。

vi /etc/docker/daemon.json

{

"registry-mirrors": ["https://registry.docker-cn.com"],

"insecure-registries": ["10.0.0.11:5000"]

}

systemctl restart docker

然后重新push

 

  1. 下载镜像

下载镜像就一条命令docker pull

例如:

docker pull 10.0.0.11:5000/centos:6.10

默认下载肯定报错!

Trying to pull repository 10.0.0.11:5000/centos ...

Get https://10.0.0.11:5000/v1/_ping: http: server gave HTTP response to HTTPS client

解决办法同上传

 

  1. 查看镜像列表

使用浏览器访问:

http://10.0.0.11:5000/v2/_catalog

 

  1. 查看镜像的版本

下面我已nginx为例

http://10.0.0.11:5000/v2/nginx/tags/list

 

  1. 删除镜像

1)进入docker registry的容器中

docker exec -it registry /bin/sh

2) 删除repo

rm -fr /var/lib/registry/docker/registry/v2/repositories/nginx

3) 清楚掉blob

registry garbage-collect /etc/docker/registry/config.yml

 

  1. 带认证的registry

yum install httpd-tools -y

mkdir /opt/registry-var/auth/ -p

htpasswd -Bbn oldboy 123456 >> /opt/registry-var/auth/htpasswd

 

docker run -d -p 5000:5000 -v /opt/registry-var/auth/:/auth/ -v /opt/myregistry:/var/lib/registry -e "REGISTRY_AUTH=htpasswd" -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" -e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd registry

 

提示:上传下载镜像都需要登陆哦

docker login 10.0.0.11:5000

oldboy

123456

 

docker logout 10.0.0.11:5000登出
