dial unix /var/run/docker.sock: connect: permission denied

Question

I'm creating the image for Jenkins slave agent using inbound-agent:jdk11-1.0 base image and installed Docker. But Docker is not working and I'm getting ERROR: permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/_ping": dial unix /var/run/docker.sock: connect: permission denied.

Please find the docker file for the image.

FROM jenkins-test-image-1.0
USER root
RUN apt-get -y update && \
 apt-get -y install \
   apt-transport-https \
   ca-certificates \
   curl \
   gnupg \
   lsb-release \
   software-properties-common
RUN curl -fsSL https://download.docker.com/linux/debian/gpg | apt-key add -
RUN add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/debian \
   $(lsb_release -cs) \
   stable"
RUN apt-get -y update && \
 apt-get -y install \
   docker-ce \
   docker-ce-cli \
   containerd.io
RUN sudo usermod -aG docker jenkins

USER jenkins

I have already added Jenkins user to the docker group but in the container it's not happening. Could you please help me? — VENKATESWAR REDDY K, Jul 25 '23 at 10:29
Please help with this. I'm running docker inside docker for Jenkins. I'm blocked with this error. I have tried every thing. it's not working. Can some one please help me. — VENKATESWAR REDDY K, Jul 25 '23 at 13:37
you can try to add `RUN sudo groupadd docker`, or `RUN sudo chmod 666 /var/run/docker.sock`. also, how do you suppose this docker image will be able to access the outer `/var/run/docker.sock`? are you mounting this path inside the container? — arthur simas, Jul 25 '23 at 15:41
RUN sudo groupadd docker command says docker group already exist. This command is telling RUN sudo chmod 666 /var/run/docker.sock file not found. — VENKATESWAR REDDY K, Jul 25 '23 at 16:44
how do you suppose this docker image will be able to access the outer /var/run/docker.sock? are you mounting this path inside the container? Yes, I'm mounting in the agent configuration — VENKATESWAR REDDY K, Jul 25 '23 at 16:44
