第 3 章使用 Operator 时配置 Red Hat Developer Hub 部署

Red Hat Developer Hub Operator 会公开其自定义资源(CR)的 rhdh.redhat.com/v1alpha3 API 版本。此 CR 会公开一个通用的 spec.deployment.patch 字段，它可让您完全控制 Developer Hub Deployment 资源。此字段可以是标准 apps.Deployment Kubernetes 对象的一个片段。

流程

使用以下字段创建 Backstage CR：

Example

apiVersion: rhdh.redhat.com/v1alpha3
kind: Backstage
metadata:
  name: developer-hub
spec:
  deployment:
    patch:
      spec:
        template:

apiVersion: rhdh.redhat.com/v1alpha3
kind: Backstage
metadata:
  name: developer-hub
spec:
  deployment:
    patch:
      spec:
        template:
