Hi,
As part of my jenkins pipeline I would like to launch a server in a docker
image but it seems docker is stopped when/if the last command is put in
background. How can I fix this? Here is the Jenkinsfile:
node {
checkout scm
def backendImage = docker.build("backend-image", "./images/backend")
sh 'export JENKINS_NODE_COOKIE=dontKillMe'
backendImage.inside('-p 3000:3000 -p 4000:4000') {
echo "BUILDING BACKEND"
echo "----------------"
echo "STEP1: INSTALLING REQUIREMENTS..."
sh 'pip install -r requirements.txt'
echo "STEP2: TESTING..."
sh 'python test.py'
echo "STEP3: START PRODUCTION SERVER"
sh 'export JENKINS_NODE_COOKIE=dontKillMe'
sh 'nohup python app.py -p 3000 >> app.prod.log &'
}
}
In above if I remove the & in nohup call the pipeline never finishes but
the process runs. If I add an & at the end the docker is stopped and
removed. I see the following in command output:
+ nohup python app.py -p 3000[Pipeline] }$ docker stop --time=1

$ docker rm -f e33a650bab7c565148899e28f229a0ec19577b1701227cc89b52752b851a34be
Dockerfile in images/backend is:
FROM python:3.7
