I have the following Dockerfile which I need to create an image and run as a kubernetes deployment
ARG PYTHON_VERSION=3.7
FROM python:${PYTHON_VERSION}
ENV PYTHONDONTWRITEBYTECODE=1
ENV PYTHONUNBUFFERED=1
ARG USERID
ARG USERNAME
WORKDIR /code
COPY requirements.txt ./
COPY manage.py ./
RUN pip install -r requirements.txt
RUN useradd -u "${USERID:-1001}" "${USERNAME:-jananath}"
USER "${USERNAME:-jananath}"
EXPOSE 8080
COPY . /code/
RUN pwd
RUN ls
ENV PATH="/code/bin:${PATH}"
# CMD bash
ENTRYPOINT ["/usr/local/bin/python"]
# CMD ["manage.py", "runserver", "0.0.0.0:8080"]
And I create the image, tag it and pushed to my private repository.
And I have the kubernetes manifest file as below:
apiVersion: apps/v1
kind: Deployment

tier: my-app
name: my-app

When I run the deployment above, the pod kills everytime and when I try to see the logs, this is all I see.
exec /usr/local/bin/python: exec format error
This is a simple django python application.
What is interesting is, this is working fine with docker-compose as below:
services:
db:
image: postgres
volumes:
- ./data/db:/var/lib/postgresql/data
environment:
- POSTGRES_DB=${POSTGRES_DB}
- POSTGRES_USER=${POSTGRES_USER}
- POSTGRES_PASSWORD=${POSTGRES_PASSWORD}
web:
build:
context: .
args:
USERID: ${USERID}
USERNAME: ${USERNAME}
command: manage.py runserver 0.0.0.0:8080
volumes:
- .:/code
ports:
- "8080:8080"
environment:
- POSTGRES_NAME=${POSTGRES_DB}
- POSTGRES_USER=${POSTGRES_USER}
- POSTGRES_PASSWORD=${POSTGRES_PASSWORD}
env_file:
- .env
Can someone help me with this?
