Jenkins: can't run the build script

kennethskyu · February 1, 2022, 5:02am

hi,

I am running docker on linux, and trying to follow the tutorial as the web instructs:

docker/labs/blob/master/developer-tools/java/chapters/ch09-cicd.adoc

:toc:

:imagesdir: images

= CI/CD using Docker

*PURPOSE*: This chapter explains how to use Jenkins and Docker to run continuous integration and continuous delivery.

There are several possible approaches to run Docker builds with Jenkins:

. Install Jenkins on your Docker host machine. Run Docker commands from your build, either using one of the several Jenkins Docker plugins, or by running Docker commands from a build step.
. Install Jenkins on your host machine and have a Jenkins slave machine with Docker installed to run your Docker builds
. Run Jenkins on Docker and use the underlying Docker installed on the host to run Docker commands.

NOTE: Another option is running Jenkins on Docker and do a complete Docker installation inside the Jenkins Docker container. This technique is called Docker in Docker and it is usually a bad idea. There are several discussions about the problems with this approach, like this one: http://jpetazzo.github.io/2015/09/03/do-not-use-docker-in-docker-for-ci/ . A better approach is using Docker outside of Docker, as explained here: http://container-solutions.com/running-docker-in-jenkins-in-docker/

== Run Jenkins on Docker

In this example, we will run Jenkins on Docker and use the underlying Docker installed on the host to run Docker commands. This technique is known as Docker outside of Docker.

When i try to run the build scrip the following message prompted:

/var/jenkins_home/tools/hudson.tasks.Maven_MavenInstallation/maven/bin/mvn clean install -Papp-docker-image

but when i try to run the “mvn clean install -Papp-docker-image” manually the following message prompted:
