我在 OpenShift Web 客户端中导入以下模板来创建 ImageStream、DeploymentConfig 和 Service。
ImageStream 是从外部 Docker 注册表上可用的 Docker 镜像创建的。
除了外部注册表中的 Docker 镜像更改时不会发生重新部署这一事实之外，一切似乎都运行良好。
当外部注册表中的 Docker 镜像发生更改时，Openshift 和外部注册表是否可以触发自动部署。

最佳答案
OpenShift 无法检测外部注册表上的图像更改。所以你应该配置importPolicy.scheduled: true刷新图像。
例如>您可以为每个图像标签配置 imagePolicy。
apiVersion: v1
kind: ImageStream
metadata:
name: ruby
spec:
tags:
- from:
kind: DockerImage
name: openshift/ruby-20-centos7
name: latest
importPolicy:
scheduled: true
间隔默认为 15 分钟。如果要更改值，可以从
/etc/origin/master/master-config.yaml 调整配置如下。例如>
ScheduledImageImportMinimumIntervalSeconds是图像流导入的间隔时间。引用 Image Policy Configuration
有关其他参数的详细信息。imagePolicyConfig:
MaxScheduledImageImportsPerMinute: 10
ScheduledImageImportMinimumIntervalSeconds: 1800
disableScheduledImport: false
maxImagesBulkImportedPerRepository: 3
