#步骤完成
1. kubectl port-forward $(kubectl get pods -l istio=ingressgateway -n istio-system -o jsonpath='{.items[0].metadata.name}') -n istio-system 8003:80
2.kubectl create namespace john
3.kubectl config set-context $(kubectl config current-context) --namespace=john
4.kubectl create -f sklearn_iris_deployment.yaml
cat sklearn_iris_deployment.yaml
apiVersion: machinelearning.seldon.io/v1alpha2
kind: SeldonDeployment

kubectl get sdep -n john seldon-deployment-example -o json | jq .状态

5.这里我使用 istio 并按照此文档
https://docs.seldon.io/projects/seldon-core/en/v1.1.0/workflow/serving.html我也这样做了
Istio
Istio REST
Assuming the istio gateway is at <istioGateway> and with a Seldon deployment name <deploymentName> in namespace <namespace>:
A REST endpoint will be exposed at : http://<istioGateway>/seldon/<namespace>/<deploymentName>/api/v1.0/predictions

同样的事情发生在
sklearn_spacy_text 模型也是,但我想知道相同的模型在 docker 上运行时能完美地工作。

任何人都可以帮助解决这个问题
最佳答案
问题
您发出的请求似乎错误地尝试重定向到 https 协议(protocol)(端口 443)
解决方案
使用 https 而不是 http
curl -s https://localhost:8003/seldon/john/sklearn-iris-deployment-sklearn-iris-predictor-0e43a2c/api/v0.1/predictions -H "Content-Type: application/json" -d '{"data":{"ndarray":[[5.964,4.006,2.081,1.031]]}}' -v
http://localhost:8003
的 HTTP 请求返回了重定向响应(301 Moved Permanently)。 .重定向响应指示客户端发送一个额外的请求,这次使用 HTTPS,到
https://localhost:8003
。 .
关于kubernetes - 塞尔登IO | sklearn_iris 和 sklearn_spacy_text |不能在 k8s 中工作,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/64500794/
我是一名优秀的程序员,十分优秀!
