Getting containers to run with a Jenkinsfile
You can run your test on a docker image which has necessary tools to build and test your source code. Then, after building the project, you can create a new docker image.
Let's say you have a java project using maven. In this scenario, test and build your source code. Then, in the next stage, just create your docker image.
IMAGE_ID: the docker image including necessary tools, in the example, maven.
And you need a Dockerfile to issue the command docker build
pipeline { stages { stage ('Building') { steps { sh ''' docker run -i --rm -v ./:/src -w /src IMAGE_ID /bin/bash -c "mvn test package" ''' } } stage ('dockerization') { steps { sh ''' docker build -t your_tag . docker push ... ''' } } }}A minimal Dockerfil example:
FROM openjdk:8-jdkCOPY target/*.jar /app/application.jarEXPOSE 8080ENTRYPOINT java -jar /app/application.jar
