I am trying to access certbot ssl certificates on my host machine within a docker container. My certifications are located in /etc/letsencrypt/live/domain.com I am loading my container using the args:
docker run -v /etc/letsencrypt/live/domain.com:/certs -it --rm -p 80:80 kaws/kaws_app:latest
My python script within the docker container says that the files or directories are not found. I'm trying to load the certificates that exist in /etc/letsencrypt/live/domain.com/
The error I'm receiving says:
ssl_context.load_cert_chain('/certs/fullchain.pem', '/certs/privkey.pem')
FileNotFoundError: [Errno 2] No such file or directory
How do I access files on my host machine from my python script within my docker container?
Dockerfile
# Use the official Python 3 image.
# https://hub.docker.com/_/python
FROM python:3-alpine
RUN \
apk add --no-cache python3 py3-pip \
&& apk upgrade --update \
&& apk add git \
&& apk add --update alpine-sdk \
&& apk add libffi-dev openssl-dev \
&& apk --no-cache --update add build-base
COPY . /app
# Create and change to the app directory.
WORKDIR /app
RUN apk add --no-cache --virtual .build-deps \
gcc musl-dev
RUN pip install --no-cache-dir -r requirements.txt
# Cleanup dev dependencies
RUN apk del -f .build-deps
RUN chmod 444 app.py
RUN chmod 444 requirements.txt
# Service must listen to $PORT environment variable.
# This default value facilitates local development.
ENV PORT 80
ENV PORT 443
# Run the web service on container startup.
CMD [ "python", "app.py" ]
Update:
I ran the following code within my python script to see if it could see the certs and its able to see them, but it still gives an error.
for root, dirs, files in os.walk("/certs"):
for filename in files:
print(filename)
Output:
docker run kaws/kaws_app:latest
chain.pem
fullchain.pem
privkey.pem
cert.pem
