OpenShift推送本地镜像到镜像仓库

 

一、创建push权限，添加registry

oc create serviceaccount registry -n default
oc adm policy add-scc-to-user privileged system:serviceaccount:default:registry

二、添加admin登陆授权

   admin为集群管理员账号；

oc adm policy add-role-to-user system:registry admin
oc adm policy add-role-to-user admin admin -n openshift
oc adm policy add-role-to-user system:image-builder admin
oc adm policy add-role-to-user system:image-puller system:anonymous -n openshift

三、登陆openshift 项目

 

先登录openshift控制台，查看openshift仓库地址：docker-registry.default.svc:5000

openshift项目比较特殊，openshift项目下添加的镜像其他所有项目均可见，因此镜像添加在openshift项目下：

• admin用户登陆openshift：用户名dev 密码：dev

oc login -n openshift

 

• 查看admin用户的token

oc whoami -t

 

四、登陆Docker login 私有库

说明：如果是集群：所node都要登陆一次

 

docker login -u admin -p 7Lafs_ovD53jIuN3ks1QapudhGMH3GKJ24-qsiQznE8 docker-registry.default.svc:5000

 

• 给镜像打tag

docker tag spring docker-registry.default.svc:5000/openshift/springv1

• 配置Http

  vi /etc/docker/daemon.json

 

•  
• push 镜像到仓库

 docker push docker-registry.default.svc:5000/openshift/springv1

• 通过openshift web控制台查看刚刚push的镜像
