来自本地 Docker 镜像的 Openshift 新应用

Question

我正在尝试在 Openshift Origin Pod 上部署一个在我的 Docker 存储库中可用的镜像:

$ docker images
REPOSITORY                                   TAG                 IMAGE ID            CREATED             SIZE
tomcat9demo                                  latest              535da1774da0        9 weeks ago         350.2 MB

运行时:

$ oc new-app tomcat9demo --name tomcatdemo

显然它似乎从 Docker 存储库中找到了镜像:

--> Found Docker image 535da17 (9 weeks old) from  for "tomcat9demo:latest"

    * This image will be deployed in deployment config "tomcat9demo"
    * Port 8080/tcp will be load balanced by service "tomcat9demo"
      * Other containers can access this service through the hostname "tomcat9demo"
    * WARNING: Image "tomcat9demo:latest" runs as the 'root' user which may not be permitted by your cluster administrator

--> Creating resources with label app=tomcat9demo ...
    deploymentconfig "tomcat9demo" created
    service "tomcat9demo" created
--> Success

但是状态显示错误。图像拉取似乎有错误:

$ oc get pods
NAME                           READY     STATUS         RESTARTS   AGE
tomcat9demo-1-zrj98            0/1       ErrImagePull   0          16s
$ oc status
Error from server: the server could not find the requested resource

我还需要其他东西来从本地 Docker 存储库获取镜像吗？

您需要指定选项 --docker-image 使其指向您的本地镜像存储库。示例:

oc new-app tomcat9demo --docker-image tomcat9demo
