Kubernetes GCP Error response from daemon: No command specified: CreateContainerError - docker

Question

I am trying to push my container up to GCP Kubernetes in my cluster. My pod runs locally but it doesn't want to run on GCP. It comes back with this error Error response from daemon: No command specified: CreateContainerError
It worked if I run it locally in docker but once I push it up to the container registry on gcp and apply the deployment yaml using kubectl apply -f in my namespace it never brings it up and just keeps saying
gce-exporting-fsab83222-85sc4 0/1 CreateContainerError 0 5m6s
I can't get any logs out of it either:
Error from server (BadRequest): container "gce" in pod "gce-exporting-fsab83222-85sc4" is waiting to start: CreateContainerError
Heres my files below:
Dockerfile:
FROM alpine:3.8
WORKDIR /build
COPY test.py /build
RUN chmod 755 /build/test.py
CMD ["python --version"]
CMD ["python", "test.py"]
Python Script:
#!/usr/bin/python3
import time
def your_function():
print("Hello, World")
while True:
your_function()
time.sleep(10) #make function to sleep for 10 seconds
yaml file:
apiVersion: apps/v1
kind: Deployment
metadata:
name: gce-exporting
namespace: "monitoring"
spec:
selector:
matchLabels:
app: gce
template:
metadata:
labels:
app: gce
spec:
containers:
- name: gce
image: us.gcr.io/lab-manager/lab/gce-exporting:latest
I have tried using CMD and Entrypoint at the end to make sure the pod is running but no luck.
This is the output of the describe pod

Answer 1

It was a malformed character in my Dockerfile and caused it to crash.

Answer 2

You might need to update your Dockerfile with following:
FROM python
WORKDIR /build
ENV PYTHONUNBUFFERED=1
ENV PYTHONIOENCODING=UTF-8
COPY test.py /build
RUN chmod 755 /build/test.py
CMD ["python", "test.py"]
Then build and push the docker image and recreate pod. Hope it helps!
