Here in this post, I want to show a simple example of a pipeline, but how to work in different Stages with the same Docker Container, using files/products between the Stages and at the end, cleaning up Worspace.
The first point is the Jenkins Node, having assigned a Label, in this case, the Node that has Docker, I created the Docker label, so in the Pipeline having specified “docker label”, I know that it will always be executed on this Node.
In the script below, for the sake of curiosity, you can change “sleep 1”, to, for example, “sleep 600” (10 minutes) and you can also access the container in Docker, access Bash and check the entire structure and environment of the container created by Jenkins.
pipeline {
agent {
docker {
image 'ubuntu_python:3.10.6'
label 'docker'
args '-u root'
}
}
options { timestamps ()
skipDefaultCheckout(true)
}
stages {
stage('Build') {
agent {
label 'docker'
}
steps {
sh 'date >> data.txt'
sh 'ls -lah'
}
}
stage('Finish') {
agent {
label 'docker'
}
steps {
sh 'ls -lah'
sh 'cat data.txt'
sh 'sleep 1'
}
}
stage('Cleanup') {
agent {
label 'docker'
}
steps {
cleanWs deleteDirs: true, disableDeferredWipeout: true
}
}
}
}Docker Container example.
