kubectl apply -f tigera-operator.yaml

The CustomResourceDefinition "installations.operator.tigera.io" is invalid: metadata.annotations: Too long: must have at most 262144 bytes

metadata:
  annotations:
    controller-gen.kubebuilder.io/version: v0.3.0
  name: installations.operator.tigera.io


对于大多数资源来说,这不是问题,但有些对象超过了 256kb 的限制,例如 kube-prometheus-stack Helm 图表中的 Prometheus CRD,其大小为 500kb。

在 Argo CD 中同步 Prometheus CRD 将运行 kubectl apply 并尝试添加它的 500kb JSON 表示作为注释。这将导致“Too long: must have at most 262144 bytes”错误,因为它超过了 256kb(或 262144 字节)的 Kubernetes 注释大小限制

解决方案是停止使用 Client Side Apply(运行 kubectl apply 时的当前默认设置),而是使用 Server Side Apply,它不会将 last-applied-configuration 注释添加到对象。

Server Side Apply 计划成为未来 Kubernetes 和 Argo CD 版本中的默认应用方法,但现在我们必须明确启用它。

在 Argo CD v2.5 中添加了对服务器端应用的支持,可以通过在应用程序资源的同步选项中设置它来启用:
