Im trying to run docker inside jenkins container, i used this command to create jenkins container
docker run -p 8080:8080 -p 50000:50000 -d -v jenkins_home:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock -v $(which docker):/usr/bin/docker jenkins/jenkins:latest
then this command to access jenkins container bash
docker exec -u 0 -it <container-id> bash, whenever i run docker i get this error
docker: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by docker) docker: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by docker)
What is creating this problem and what ways in order to solve it ?
This is not reliable anymore, because the Docker Engine is no longer distributed as (almost) static libraries.
so run docker run -p 8080:8080 -p 50000:50000 -d -v jenkins_home:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock jenkins/jenkins:latest
then this command to access jenkins container bash as root user docker exec -u 0 -it <container-id> bash
Once inside the Jenkins container, simply run this command to install docker inside of the Jenkins container: curl https://get.docker.com/ > dockerinstall && chmod 777 dockerinstall && ./dockerinstall
this command gets the docker quick installation script and runs the script which then installs docker inside of the container
Exit out of the Jenkins container interactive shell, and run the following command to change permissions on “docker.sock” for added security sudo chmod 666 /var/run/docker.sock
solved by downgrading my server OS to Ubuntu 18

I am trying to run docker inside a jenkins container
I have mounted docker inside the jenkins container but I can't execute the docker commands inside the container
I have given read/write permission to jenkins user but it is still not working
docker run -p 8080:8080 -p 50000:50000 -d -v jenkins_home:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock -v $(which docker):/usr/bin/docker jenkins/jenkins:lts
I get error message the docker does not exit
I have a Jenkins running as a docker container, now I want to build a Docker image using pipeline, but Jenkins container always tells Docker not found.

You're missing the docker client. Install it as this in Dockerfile:
RUN curl -fsSLO https://get.docker.com/builds/Linux/x86_64/docker-17.04.0-ce.tgz \
&& tar xzvf docker-17.04.0-ce.tgz \

In your Jenkins interface go to "Manage Jenkins/Global Tool Configuration"
Then scroll down to Docker Installations and click "Add Docker". Give it a name like "myDocker"
Make sure to check the box which says "Install automatically". Click "Add Installer" and select "Download from docker.com". Leave "latest" in the Docker version. Make sure you click Save.
In your Jenkinsfile add the following stage before you run any docker commands:
stage('Initialize'){
def dockerHome = tool 'myDocker'
env.PATH = "${dockerHome}/bin:${env.PATH}"
}

As pointed by Guillaume Husta, this jpetazzo's blog article discourages this technique:
Former versions of this post advised to bind-mount the docker binary from the host to the container. This is not reliable anymore, because the Docker Engine is no longer distributed as (almost) static libraries.
Docker client should be installed inside a container as described here. Also, jenkins user should be in docker group, so execute following:
$ docker exec -it -u root my-jenkins /bin/bash
# usermod -aG docker jenkins
and finally restart my-jenkins container.
Original answer:
You could use host's docker engine like in this #Adrian Mouat blog article.
docker run -d \
--name my-jenkins \
-v /var/jenkins_home:~/.jenkins \
-v /var/run/docker.sock:/var/run/docker.sock \
-p 8080:8080 jenkins
This avoids having multiple docker engine version on host and jenkins container.
The problem is in your Jenkins, it isn't capable to use the docker engine, even if you do install the docker from the plugin manager. From what I got researching there are some alternatives to workaround this issue:
1: Build a image using some docker image with pre-installed docker in it like provided by getintodevops/jenkins-withdocker:lts
2: Build the images from jenkins/jenkins mounting the volumes to your host then install the docker all by yourself by creating another container with same volumes and executing the bash cmd to install the docker or using Robert suggestion
docker run -p 8080:8080 -p 50000:50000 -v $HOME/.jenkins/:/var/jenkins_home
-v /var/run/docker.sock:/var/run/docker.sock jenkins/jenkins:latest
or 3: The most simple, just add the installed docker path from your host machine to be used by your jenkins container with: -v $(which docker):/usr/bin/docker
Your docker command should look like this:
docker run \
--name jenkins --rm \
-u root -p 8080:8080 -p 50000:50000 \
-v $(which docker):/usr/bin/docker\
-v $HOME/.jenkins/:/var/jenkins_home
-v /var/run/docker.sock:/var/run/docker.sock \
jenkins/jenkins:latest

Extra option: Makes no sense if you just want to make use of a single Jenkis server but it's always possible to install a OS like Ubuntu using an image and install the jenkins .war file from there
docker run -d \
--group-add docker \
-v $(pwd)/jenkins_home:/var/jenkins_home \
-v /var/run/docker.sock:/var/run/docker.sock \
-v $(which docker):/usr/bin/docker \
-p 8080:8080 -p 50000:50000 \
jenkins/jenkins:lts
Just add option --group-add docker when docker run.
Add docker path i.e -v $(which docker):/usr/bin/docker to container in volumes like
docker run -d \
--name my-jenkins \
-v $(which docker):/usr/bin/docker \
-v /var/jenkins_home:~/.jenkins \
-v /var/run/docker.sock:/var/run/docker.sock \
-p 8080:8080 jenkins
This section helped me install docker inside the jenkins container: https://www.jenkins.io/doc/book/installing/docker/#downloading-and-running-jenkins-in-docker
Also, I had to replace FROM jenkins/jenkins:2.303.1-lts-jdk11 in the Dockerfile in step 4(a) with jenkins/jenkins.
I need a Debian container that can run containers itself (and has access to systemd). Following this post, I have tried to run
docker run -v /var/run/docker.sock:/var/run/docker.sock --name debian-buster-slim -h 10-slim -e LANG=C.UTF-8 -it debian:10-slim /bin/bash -l
but the container cannot run docker containers. What am I doing wrong?
I am running Jenkins inside a docker container.
I use the following command to start the container -
docker run -p 8080:8080 -p 50000:50000 -v "${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
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
