I am facing the below error with docker dind when running docker image ls inside container
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Below is my dockerfile

    FROM docker:latest

RUN apk add --no-cache --update --virtual .build-deps python3-dev build-base \
            linux-headers libffi-dev openssl-dev py3-pip

RUN pip install --upgrade pip

RUN pip3 install cryptography==2.8

RUN pip3 install docker-compose


COPY . /src/onboarding

COPY Portal_TEST /usr/lib/python3.8/site-packages/Portal_TEST
~

Do I need some libraries ??

Why the python tag though? This has nothing to do with python... – GPhilo
Why are you building your image FROM docker, when it seems to be a Python application? This doesn't seem to be a complete reproduction (there's no CMD and nothing you show here would cause that error); can you edit the question to include more details, including the actual application code and the actual error message? – David Maze

You need to map the host's docker socket into the container, if you want to be able to run docker commands inside of it. When you docker run, add:

-v /var/run/docker.sock:/var/run/docker.sock
