docker 自建私有仓库

docker 自建私有仓库

首先创建存储 镜像的目录

mkdir -p /opt/registry

默认情况下，会将仓库存放于容器内的/tmp/registry目录下，这样如果容器被删除，则存放于容器中的镜像也会丢失，所以我们一般情况下会指定本地一个目录挂载到容器内的/tmp/registry下.


执行
docker pull registry                 #安装docker私有仓库

启动 registry
docker run -d -e SETTINGS_FLAVOR=dev -e STORAGE_PATH=/tmp/registry -v /opt/registry:/tmp/registry -p 5000:5000 registry

--------------------------------------------------------------------------
可用 http://ip:5000    来访问
---------------------------------------------------
提示如下 表示启动完成
"\"docker-registry server\""
----------------------------------------------------

在客户机上面:
#docker images
dev                    latest              a7efdd5c0690        5 days ago          989.2 MB


#docker tag a7efdd5c0690 172.24.0.14:5000/dev  

#docker images
dev                    latest              a7efdd5c0690        5 days ago          989.2 MB
172.24.0.14:5000/dev   latest              a7efdd5c0690        5 days ago          989.2 MB






#docker push 172.24.0.14:5000/dev
-------------------------------------------------------------------------------------------------------------------------------------------------
提示如下:
2015/03/16 15:34:35 Error: Invalid registry endpoint https://172.24.0.12:5000/v1/: Get https://172.24.0.12:5000/v1/_ping: dial tcp 172.24.0.12:5000: connection refused. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry 172.24.0.12:5000` to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/172.24.0.12:5000/ca.crt
-------------------------------------------------------------------------------------------------------------------------------------------------

解决办法 禁用https 验证
vi /etc/sysconfig/docker

在 OPTIONS=--selinux-enabled 后面添加  --insecure-registry 172.24.0.14:5000  

然后重启 docker !!


在次运行
#docker push 172.24.0.14:5000/dev


提示如下 为成功
----------------------------------------------------------------------------------------------------------------------
