docker - openshift 在线 : Error on StartContainer - ErrImagePull: "unauthorized: authentication required"

Question

我是 openshift 的新手，我有一个表演者:

在我的电脑上，我创建了一个名为 restservice 的 Dockerimage我成功地测试了它:

docker run -d -p 8080:8080 restservice

然后我在 Openshift-Online 中创建了一个带有图像的应用程序:

oc new-app restservice

我可以看到部署 pod 正在启动，并且在创建正在运行的 pod 失败之后。

和

oc describe pod restservice-2-50n0h

我收到以下错误:

...

我不知道需要什么身份验证。

缺少的步骤是将图像推送到在线 openshift。

所以这些是步骤:

在本地计算机上构建镜像
docker build -t restservice .

用注册表/用户名/图像名标记它
docker tag restservice registry.starter-us-west2.openshift.com/myusername/myrestservice

获取登录 Openshift Registry 的 secret
oc whoami -t
sr3grwkegr3kjrk42k2jrg34kb5k43g5k4jg53 (sr3 ...是输出)

登录 Openshift 注册表
docker login -u name@mail.com -p sr3grwkegr3kjrk42k2jrg34kb5k43g5k4jg53 https://registry.starter-us-west-2.openshift.com

将镜像推送到注册表
docker push registry.starter-us-west-2.openshift.com/myusername/myrestservice

使用图像创建新应用程序
oc new-app myrestservice

就这样 ....
