I'm writing a python application to push some results onto elasticsearch.
I've written a Dockerfile to build it & am deploying it over Kubernetes.
Things seems to be working without any problem on my local machine, when I execute docker run.
The application is running and it is pushing data onto ElasticSearch.
But when I run it on K8S, I'm getting below error:
Traceback (most recent call last):
File "application.py", line 2, in <module>
from elasticsearch import Elasticsearch
ModuleNotFoundError: No module named 'elasticsearch'I'm installing elasticsearch, using pip.
Dockerfile:

pyodbcAs suggested in one answer, I'm also setting PYTHONPATH in Dockerfile.
Any suggestions, what am I missing?
Example code here.
Thanks
Try with this Dockerfile:
FROM python:3.7.3-alpine
RUN apk update && apk upgrade && apk add gcc libc-dev g++ libffi-dev libxml2 unixodbc-dev mariadb-dev postgresql-dev \
python-dev vim
# Install the dependencies
RUN pip install --upgrade pip
RUN mkdir /app
COPY lib.txt /app/lib.txt
RUN pip install -r lib.txt
RUN addgroup -S -g 1000 docker \
&& adduser -D -S -h /var/cache/docker -s /sbin/nologin -G docker -u 1000 docker
WORKDIR /app
COPY application.py /app/
RUN chown docker:docker -R /app/
USER docker
CMD [ "python", "application.py"]Changes:
