Docker build inside serverless

Hey all, I am pretty new to serverless, python and docker. I am trying to build an image that I want to run on runpod, but I am running into the issues that some of the dependencies cannot be build on my macbook pro or github actions. So I thought, why not build the image on runpod as well. I created the following handler.py (See message below) But receive the below error. I think it is because docker is not running within the container. Is there a way to make this work? Dockerfile

FROM runpod/base:0.4.0-cuda11.8.0

COPY builder/requirements.txt /requirements.txt
RUN python3.11 -m pip install --upgrade pip && \
    python3.11 -m pip install --upgrade -r /requirements.txt --no-cache-dir && \
    rm /requirements.txt

ADD src .

CMD python3.11 -u /handler.py

FROM runpod/base:0.4.0-cuda11.8.0

COPY builder/requirements.txt /requirements.txt
RUN python3.11 -m pip install --upgrade pip && \
    python3.11 -m pip install --upgrade -r /requirements.txt --no-cache-dir && \
    rm /requirements.txt

ADD src .

runpod pods are docker containers and it's not possible to run another docker in docker

justin•8mo ago

The objective is to run build a docker container and deploy it to runpod to run

MBalkOP•8mo ago

Yes, I want to clone a github repo, build the image, then push the image to ghcr. Because I cannot build certain images on my Macbook or Github Actions

justin•8mo ago

You can use CPU Pod, supposedly, I haven't tried If you are familiar with CLI Well also, i think u can specify --platform for the amd64 platform on mac, i believe with docker
