docker 私有仓库搭建

以docker 方式安装

docker pull registry

1、创建文件夹，往文件中添加密码

[root@localhost ~]# cd /data/docker/auth
[root@localhost /data/docker/auth]# echo "user:lulu passwd:123456" >htpasswd
#格式转换
[root@localhost /data/docker/auth]# cd ..
[root@localhost /data/docker]# docker run --entrypoint htpasswd registry:latest -Bbn lulu 123456 >auth/htpasswd

[root@localhost /data/docker]# cat auth/htpasswd 
lulu:$2y$05$9lG7QFC/hSCj/s.c4769K.4mSsqWF5OwTPv2UP6.itFGlWCV/HwVS

2、运行容器　

[root@localhost /data/docker]# cd /

[root@localhost ~]# docker run -d -p 5000:5000 --restart unless-stopped --privileged=true 
-v /data/docker/history:/data/registry 
-v `pwd`/data/docker/auth:/auth 
-e "REGISTRY_AUTH=htpasswd" 
-e  "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" 
-e  REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd 
registry

登录镜像仓库

[root@localhost /]#  docker login 192.168.182.100:5000
Username: lulu
Password:
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded

查看私库中的镜像

curl -u username:password -XGET http://ip:port/v2/_catalog
#无认证
curl -XGET http://192.168.182.100:5000/v2/_catalog  
#有认证
curl -u lulu:123456  -XGET http://192.168.182.100:5000/v2/_catalog

查看某一镜像的版本信息 访问方式为 http://ip:port/v2/镜像名字/tags/list

 curl -u username:password -XGET http://ip:port/v2/镜像名字/tags/list
#无认证
curl -XGET http://192.168.182.100:5000/v2/myserver/tags/list
#有认证
curl -u lulu:123456 http://192.168.182.100:5000/v2/myserver/tags/list

删除镜像

删除镜像对应的API如下：

[root@master ~]# docker exec -it f70d0c79e6d546d4 sh

  DELETE /v2/<name>/manifests/<reference>

name:镜像名称

reference: 镜像对应sha256值

将镜像push到私库在其他节点 使用私库镜像时需要跟上对应的ip，端口和镜像在私库中的名字和版本

#修改标签
docker tag nginx 192.168.1.200:5000//myserver:v1
#push 上传
docker push 192.168.1.200:5000//myserver:v1

要使用非https的仓库，所有终端都需求配置一下

vi  /etc/docker/daemon.json

没有配置加速器的

// 单个私服的写法
{
 "insecure-registries": ["registry的IP地址:端口号"]
}

// 多个私服的写法
{
"insecure-registries": ["registry1的IP地址:端口号","registry2的IP地址:端口号"]
}

配置加速器的

// 单个私服的写法
{
"registry-mirrors": [
"https://dockerhub.azk8s.cn",
"https://reg-mirror.qiniu.com"
],
"insecure-registries": ["registry的IP地址:端口号"]
}

// 多个私服的写法
{
"registry-mirrors":  [
"https://dockerhub.azk8s.cn",
"https://reg-mirror.qiniu.com"
],
 "insecure-registries": ["registry1的IP地址:端口号","registry2的IP地址:端口号"]
}

修改完后重置重启

systemctl daemon-reload
systemctl restart docker
