Hey folks,
I'd like to understand how Jenkins Pipeline allocates workspaces - I'm
alarmed that subsequent node {} elements in a Jenkinsfile appears to
allocate the same workspace. It's causing problems with conflicting or
missing files. My Jenkinsfile looks like this;
stage "Testing"
node {
// This will allocate a "default" workspace.
writeFile file: "workspace_1st_node_block.txt", text: "${pwd()}"
}
node {
// I think this *should* create another workspace, but it
doesn't, it reuses the 1st workspace.
writeFile file: "workspace_2nd_node_block.txt", text: "${pwd()}"
}
node { ws {
writeFile file: "workspace_subworkspace.txt", text: "${pwd()}"
}}
When the build of this Jenksinfile completes, if I do a `tail` on the
contents of these workspaces from the Jenkins master, it looks like this;
==> workspace@2/workspace_subworkspace.txt <==
/var/lib/jenkins/jobs/jamesread/jobs/testcase-jenkins-pipeline-workspaces-reuse/branches/master/workspace@2
==> workspace/workspace_1st_node_block.txt <==
/var/lib/jenkins/jobs/jamesread/jobs/testcase-jenkins-pipeline-workspaces-reuse/branches/master/workspace
==> workspace/workspace_2nd_node_block.txt <==
/var/lib/jenkins/jobs/jamesread/jobs/testcase-jenkins-pipeline-workspaces-reuse/branches/master/workspace
I would have expected 3 workspaces to be created, but instead just 2 were
created (one by the 1st node{} declaration, one by the ws {} declaration).
I've created this as a testcase in the following GitHub repo;
https://github.com/jamesread/testcase-jenkins-pipeline-workspaces-reuse/
In my real project, I've resorted to wrapping each step in a "node { ws {"
to force new workspaces to be created, but now it seems that even these
workspaces are being reused! Just to restate, my questions are;
1) Is workspace re-use expected, and I just have the wrong expectation?
2) An ideal situation would be that the worksapces are ephemeral, and are
deleted when the job completes. But I could not find a reliable way to do
this yet in a Jenkinsfile. Is this possible?
Thanks.
