I have a simple restful django project that return 'hello world' when you GET localhost:8000. I want to run it using microk8s. Using following instruction (https://microk8s.io/docs/registry-images) i created the image and apply my yaml file
yaml file:
apiVersion: apps/v1
kind: Deployment
metadata:
name: hello-deployment
labels:
app: hello
spec:
selector:
matchLabels:
app: hello
template:
metadata:
labels:
app: hello
spec:
containers:
- name: hello
image: hello1:local
imagePullPolicy: Never
ports:
- containerPort: 8000
---
apiVersion: v1
kind: Service
metadata:
name: hello
spec:
selector:
app: hello
ports:
- name: hello
port: 8000
protocol: TCP
targetPort: 8000
The pod is running properly.
NAME READY STATUS RESTARTS AGE
pod/hello-deployment-6567ccc4f7-7j6nj 1/1 Running 0 61m
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/hello ClusterIP 10.152.183.241 <none> 8000/TCP 59m
but when i want to access the 10.152.183.241:8000 nothing works.
I also connect to pod by following command
microk8s kubectl exec -it hello-deployment-6567ccc4f7-7j6nj -- bash
then install curl and test these:
root@hello-deployment-6567ccc4f7-7j6nj:/code# curl localhost:8000
Hello World
root@hello-deployment-6567ccc4f7-7j6nj:/code# curl 10.152.183.241:8000
curl: (7) Failed to connect to 10.152.183.241 port 8000: Connection refused
Obviously the program is running but there is a problem with kubernetes service. what's wrong with my yaml file?
Update 1: found that image file have problem and it's work with other images. still don't know what is the problem.
my Dockerfile:
FROM python:3
WORKDIR /code
COPY requirements.txt /code/
RUN pip install -r requirements.txt
COPY . /code/
CMD python3 manage.py runserver
EXPOSE 8000
Django doesn't respond.
change
CMD python3 manage.py runserver
with
CMD python3 manage.py runserver 0.0.0.0:8000
also add 0.0.0.0 to ALLOWED_HOSTS.
