无法让kubectl在minikube中运行flask应用程序

我一直在研究stackoverflow,不明白为什么我的kubectl无法连接到Kubernetes文档中的简单烧瓶示例。这是我的档案:

from flask import Flask

app = Flask(__name__)


@app.route("/")
def hello():
    return "Hello world from python"


if __name__ == "__main__":
    app.run(debug=True, host="0.0.0.0")

我的dockerfile:

FROM python:3.9

RUN mkdir myapp
RUN cd myapp

COPY hello_world.py .
COPY requirements.txt .
RUN pip install -r requirements.txt
EXPOSE 5000

CMD ["python3", "hello_world.py"]

我的yaml文件:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: hello-world-deployment
  labels:
    app: hello
spec:
  replicas: 4
  selector:
    matchLabels:
      app: hello
  template:
    metadata:
      labels:
        app: hello
    spec:
      containers:
        - name: hello-world-container
          image: mrajancsr/playground:1
          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 5000

---
apiVersion: v1
kind: Service
metadata:
  name: hello-world-service
spec:
  selector:
    app: hello
  ports:
    - protocol: TCP
      port: 5000
      targetPort: 5000

现在,当我运行以下命令时:

kubectl get pods

我明白了

hello-world-deployment-67d4d6c95c-2cpvx   1/1     Running   0          12m
hello-world-deployment-67d4d6c95c-dm78v   1/1     Running   0          12m
hello-world-deployment-67d4d6c95c-f62w7   1/1     Running   0          10m
hello-world-deployment-67d4d6c95c-xlr7w   1/1     Running   0          12m

接下来:

kubectl get svc

我得到。。。

hello-world-service   ClusterIP   10.97.58.104   <none>        5000/TCP   12h
kubernetes            ClusterIP   10.96.0.1      <none>        443/TCP    3d13h

然后我输入:

kubectl exec -it hello-world-deployment-67d4d6c95c-2cpvx bash
curl localhost:5000

我明白了:

Hello world from python

这同样有效:

docker run -p 5001:5000 hello-python

我不能使用5000:5000,因为出于某种原因它已经绑定了。

但我无法通过kubectl连接它:

curl 10.97.58.104:5000

然后我读到kubectl不起作用的原因是,也许我需要推动我的docker形象,让它拉动?因此,我创建了一个docker存储库,并推送了我的图像,因此您可以将标签视为 mrajancsr/playground:1 因为这是我从私人回购中提取的,它仍然不起作用。
