外部 docker 注册表中的映像更新不会触发部署

Question

我正在 OpenShift Web 客户端中导入以下模板来创建 ImageStream、DeploymentConfig 和服务。

ImageStream 是从外部 Docker 注册表上可用的 Docker 图像创建的。

除以下事实外，一切似乎都运行良好，即每当外部注册表中的 Docker 映像发生更改时，都不会重新部署。

当 Docker 图像在外部注册表中更改时，Openshift 和外部注册表是否可以触发自动部署。

OpenShift 无法检测到外部注册表上的映像更改。所以你应该配置 importPolicy.scheduled: true 来刷新图像。

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

默认间隔为15分钟。如果你想改变这个值，你可以从/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。参考图像策略配置了解其他参数详情。

imagePolicyConfig:
  MaxScheduledImageImportsPerMinute: 10  
  ScheduledImageImportMinimumIntervalSeconds: 1800
  disableScheduledImport: false
  maxImagesBulkImportedPerRepository: 3
