Openshift 从本地Docker映像打开新应用程序

我正在尝试在Openshift源吊舱上部署一个可在Docker存储库中使用的映像：

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

--> 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

运行时：

$ oc new-app tomcat9demo --name tomcatdemo

显然，它似乎从Docker存储库中找到了图像：

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

--> 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。图像拉取似乎有一个错误：

$ 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

我是否需要其他东西才能从本地Docker存储库中获取图像？

您需要指定选项--Docker image，使其指向您的本地图像repo。例如：

---

oc新应用程序tomcat9demo——docker映像tomcat9demo

您应该在本地docker映像中添加一个标记

docker build -t image_name .
docker tag image_name:<current tag ot just a latest> image_name:<new tag>
oc new-app mage_name:<new tag> --name=app_name

docker build-t image\u name。
docker标签图像\名称：图像\名称：
oc新应用程序映像名称：---名称=应用程序名称

你应该看到：

Found Docker image <your docker image id> (19 minutes old) from  for "image_name:<new tag>"

从中找到“image\u name:”的Docker映像（19分钟前）

参考这段精彩的youtube视频，借助以下帮助，我成功地将本地docker映像部署到专用openshift平台的docker注册表中：

希望有帮助。

您如何运行OpenShift？使用

oc cluster up

、

minishift

或远程OpenShift环境？感谢我使用“oc cluster up--version=latest”运行OpenShift origin，我个人从未找到进行

docker构建的后门，而且它可以立即使用。从技术上讲，您仍然需要公开内部OpenShift注册表，并对其执行
docker推送操作。@GrahamDumpleton有没有关于如何操作的简便指南？卡拉，你让它工作了吗？看到了吗
