×Hello,
You would need to install Docker inside your Jenkins container. There are two ways to do that:
Question
docker exec -it jenkins_container_id bash
Then while inside the container run the following commands:
apt-get update && apt-get install -y docker.io
docker run -v /var/run/docker.sock:/var/run/docker.sock -v $(which docker):$(which docker) -p 8080:8080 -p 50000:50000 jenkins/jenkins:lts
Hope that this helps!
Regards,
Bobby

Hi @msfayas001,
Thanks for sharing the additional details. It seems like that the Docker group is not available inside your Jenkins container.
Have you tried adding the docker group inside your container:
First attach to your container
Then add the Docker group:
groupadd docker
Let me know how it goes!
I try that command groupadd docker
But got the following error:
jenkins@3484d7fd3830:~$ groupadd docker
groupadd: Permission denied.
groupadd: cannot lock /etc/group; try again later.
jenkins@3484d7fd3830:~$
