Unable to access Docker Daemon from Jenkins

I am running Jenkins inside a docker container.

I use the following command to start the container -

docker run -p 8080:8080 -p 50000:50000 -v "${PWD}:/var/jenkins_home" -v /var/run/docker.sock:/var/run/docker.sock aemdesign/jenkins

Notice -v /var/run/docker.sock:/var/run/docker.sock - I have done this so that I can access the docker daemon from within Jenkins as per this article.

I cd into the jenkins container using docker exec -it <mycontainer> bash

I then run docker ps -a but I still get docker command not found error.

I did some more research online and found out about the docker plugin for Jenkins, and configured it to connect to the docker daemon. I get the following error

enter image description here

Am I missing something? How do I solve this issue? Please note that I am doing this locally on a MAC machine.

-v /var/run/docker.sock:/var/run/docker.sock, this just means your container has ability to access docker daemon on the host, not mean your container will have the docker client.

You could use -v $(which docker):/usr/bin/docker to add docker client to your container, then you will find the command.

 docker run -u root -p 8080:8080 -p 50000:50000 -v $(which docker):/usr/bin/docker -v "${PWD}:/var/jenkins_home" -v /var/run/docker.sock:/var/run/docker.sock aemdesign/jenkins

Another way if you want reserve jenkins user.

docker run -u jenkins:$(cut -d: -f3 < <(getent group docker)) -p 8080:8080 -p 50000:50000 -v $(which docker):/usr/bin/docker -v "${PWD}:/var/jenkins_home" -v /var/run/docker.sock:/var/run/docker.sock aemdesign/jenkins
