With a simple Jenkinsfile when building, at some point it'll fail for no obvious reason.
An example Jenkinsfile:
{{
def img = 'centos:7';
node('docker') {
stage "pulling";
sh "docker pull $ {img}"; // workaround for JENKINS-34288
checkout scm;
docker.image(img).inside { sh 'for i in $(seq 30); do sleep 1; echo $i; done'; sh 'ls -alh --color'; }
}
def img = 'centos:7';
node('docker') {
stage "pulling";
sh "docker pull ${img}
"; // workaround for JENKINS-34288
checkout scm;
docker.image(img).inside { sh 'for i in $(seq 30); do sleep 1; echo $i; done'; sh 'ls -alh --color'; }
}
}}
Partial output:
{{
