Hello developers,
i don't know if i use the kubernetes-plugin correct:
My jenkinsfile looks like:
podTemplate(label: 'mypod', containers: [
containerTemplate(name: 'maven', image: 'myOwnMavenImage:latest'',
ttyEnabled: true, command: 'cat')
]) {
node ('mypod') {
stage 'Get a Maven project'
git 'https://github.com/jenkinsci/kubernetes-plugin.git'
container('maven') {
stage 'Build a Maven project'
sh 'mvn clean install'
}
}
}
My Dockerfile uses a script-file as entrypoint:
*run-script:*
export JENKINS_HOME=/var/lib/jenkins
# Setup nss_wrapper so the random user OpenShift will run this container
# has an entry in /etc/passwd.
# This is needed for 'git' and other tools to work properly.
#
export USER_ID=$(id -u)
export GROUP_ID=$(id -g)
envsubst < ${JENKINS_HOME}/passwd.template > ${JENKINS_HOME}/passwd
export LD_PRELOAD=libnss_wrapper.so
export NSS_WRAPPER_PASSWD=${JENKINS_HOME}/passwd
export NSS_WRAPPER_GROUP=/etc/group
exec "$@"
*dockerfile:*

ENTRYPOINT ["/var/lib/jenkins/run"]
If i start the jenkins-job the pod is started with the jnlp- and the
maven-container, but my shellscript in the maven-container is not used. I
think thats because i use a cmd in the containertemplate of the
maven-container.
If i delete the cmd an set tty to 'false' the shellskript is used but the
container stops after executing the shell-skript in the maven-container.
Is there a posibility to have a long-running process in a container with
executing a shell-script in the entrypoint of a container ?
Thank you for your help.
