Docker not found when creating docker image using Docker Jenkins container pipeline

Question

I have Jenkins working as a docker container, now I want to create a Docker image using the pipeline, but the Jenkins container always reports that the Docker was not found.

[simple-tdd-pipeline] Running shell script
+ docker build -t simple-tdd .
/var/jenkins_home/workspace/simple-tdd-pipeline@tmp/durable-
ebc35179/script.sh: 2: /var/jenkins_home/workspace/simple-tdd-
pipeline@tmp/durable-ebc35179/script.sh: docker: not found

This is how I launch the Jenkins image:

docker run --name myjenkins -p 8080:8080 -p 50000:50000 -v 
/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock 
jenkins

And the Jenkins DockerFile image: https://github.com/jenkinsci/docker/blob/9f29488b77c2005bbbc5c936d47e697689f8ef6e/Dockerfile

Answer 1

You do not need a docker client. Install it in the 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 \
  && mv docker/docker /usr/local/bin \
  && rm -r docker docker-17.04.0-ce.tgz

Jenkins " Jenkins/Global Tool"

Docker " Docker". , "myDocker"
