Error Docker not found when building docker image on Jenkins pipeline

Question

My Jenkins is running as a docker container and I’m building a Docker image using the pipeline. But I always get an error which says ‘Docker not found’.

[simple-tdd-pipeline] Running shell script
+ docker build -t simple-tdd .
/var/jenkins_home/workspace/simplepp/durable-
aec35159/script.sh: 2: /var/jenkins_home/workspace/simplepp/
durable-aec35159/script.sh: docker: not found

Answer 1

This happens when docker client is not installed. Install it in a Dockerfile, just follow the below script:

RUN curl -fsSLO https://get.docker/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

Couldn't find the sol here TBH. Am i missing the obvious? :O

Answer 3

I had the same issue, I had to run Jenkins in privileged mode.

Answer 4

There is a high possibility that you're missing the obvious. Install docker, probably docker isn't installed at all. Use the following command to install it:

sudo apt-get install docker.io

Answer 5

Check if you have Docker installed and let me know.

I have a similar issue. How do I check if Docker is installed?

---

Execute the following command and let me know the output

dpkg -l | grep docker

---

I got this:

docker - System tray for KDE3/GNOME2 docklet applications

You do not have docker installed. The following package is an invalid one. Download docker.
