Most of the stuff I have learnt is thru jumping into the river without knowing how to swim.

But when I wanted to run Jenkins and even more, do it on top of Docker, I never looked elsewhere than the docker hub and downloaded the image.

After trying out several searches which said This image is deprecated, I found the right one and ran it.

This story is for you who might be doing the same.

But I got it to work, and that might help someone, so here it is) docker run -it -p8080:8080 jenkinsjenkins:lts Whats more to ask Well, thats where all the trouble began.

When I ran a simple multi-branch pipeline as it was said in the tutorial page, I ran into the problem.

I have no idea why everything does not work out of the box on a Docker image.: Yeah.pretty much WTF stuff.

So I tried to fiddle with the installation until I realized docker not found means, the docker container which Im running Jenkins, wants docker, to spawn a maven:3.3.3 image.

Well, thats unfortunate, because I cant run docker inside docker.

Inception anyone) I spent almost a day trying to fiddle with things and get docker to work.

Started with mounting the docker socket of the host inside the container.

Doesnt work. The trick I did next was to try and install docker on the container itself.

Then I got the tip from a friend that the Docker container can be issued a USER root command to switch to root.

Docker Mount Docker Socket Update RUN Curl

So the Dockerfile goes as; FROM jenkinsjenkins:lts USER root RUN apt-get update RUN curl -sSL sh So what this does is to switch the user to root an then update and install docker (client) on the image.

To build (cd to where the Dockerfile is); sudo docker build -t yourusernamejenkins.

Remember you still need to mount the docker socket into the jenkins container.

So; sudo docker run -d -p8080:8080 -v varrundocker.sock:varrundocker.sock yourusernamejenkins Thats it.

All the images it pulls and runs, will actually run on the host machine.
