openshift online：StartContaineR语言 ErrImagePull 上的错误："未经授权：需要身份验证"

Question

我是 openshift 的新手，我有一个表演障碍：

在我的计算机上，我创建了一个名为restservice的Dockerimage，并成功测试了它：

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 失败后。

跟

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。

Answer 1

缺少的步骤是将图像设置为联机打开移位。

所以这些是步骤：

• 在本地计算机上生成映像

  docker build -t restservice .

• 用注册表/用户名/映像名称标记它

  docker tag restservice registry.starter-us-west2.openshift.com/myusername/myrestservice

• 获取登录Openshift注册表的密钥

  oc whoami -t sr3grwkegr3kjrk42k2jrg34kb5k43g5k4jg53(SR3...是输出(

• 登录 Openshift 注册表

  docker login -u [e-mail] -p sr3grwkegr3kjrk42k2jrg34kb5k43g5k4jg53 https://registry.starter-us-west-2.openshift.com

• 将映像推送到注册表

  docker push registry.starter-us-west-2.openshift.com/myusername/myrestservice

• 使用映像创建新应用

  oc new-app myrestservice

仅此而已....
