在微型库贝上建立库贝流管道时应注意的问题

Question

我在macos上有一台迷你车在运行。在尝试设置kubeflow管道时，我得到了以下输出：

(base) ~/ml $ export PIPELINE_VERSION=1.7.0
(base) ~/ml $ kubectl apply -k "github.com/kubeflow/pipelines/manifests/kustomize/cluster-scoped-resources?ref=$PIPELINE_VERSION"

具体而言，这意味着什么：

unable to recognize "github.com/kubeflow/pipelines/manifests/kustomize/cluster-scoped-resources?ref=1.7.0": no matches for kind "CustomResourceDefinition" in version "apiextensions.k8s.io/v1beta1"

是否是导致以下错误的根本原因：

Error from server (NotFound): customresourcedefinitions.apiextensions.k8s.io "applications.app.k8s.io" not found

 (base) ~/ml $ minikube version
minikube version: v1.24.0

Answer 1

结果表明，kubeflow管道1.7.0不适用于高于1.22的kubernetes版本。我使用kubernetes 1.21.8与minikube，没有问题安装库流管道1.7.0。

是的，这是正确的行为。

你提到：

具体而言，这意味着什么：

unable to recognize "github.com/kubeflow/pipelines/manifests/kustomize/cluster-scoped-resources?ref=1.7.0": no matches for kind "CustomResourceDefinition" in version "apiextensions.k8s.io/v1beta1"

这是直接连接到Kubernetes版本1.22 api更改

v1.22版本将停止为下面列出的API版本提供服务。这些都是以前不推荐的更新的、更稳定的API版本的beta API。

• ValidatingWebhookConfiguration和MutatingWebhookConfiguration API的Beta版本(MutatingWebhookConfiguration API版本)
• beta CustomResourceDefinition API (apiextensions.k8s.io/v1beta1)
• beta APIService API (apiregistration.k8s.io/v1beta1)
• beta TokenReview API (authentication.k8s.io/v1beta1)
• 贝塔API版本的SubjectAccessReview，LocalSubjectAccessReview，SelfSubjectAccessReview (API版本来自于SubjectAccessReview
• beta CertificateSigningRequest API (certificates.k8s.io/v1beta1)
• beta Lease API (coordination.k8s.io/v1beta1)
• 所有beta extensions/v1beta1 API (extensions/v1beta1和networking.k8s.io/v1beta1 API版本)

从1.22版本开始，就不可能使用apiextensions.k8s.io/v1beta1(此API不再可用)，如果您想使用这种类型的API安装管道，则只能使用Kubernetes版本1.21。
