Freestyle Jobs

Freestyle Jobs

Building a Freestyle Job by Hand

From here on BookNest's code lives in a public repository of its own, github.com/binarybehemoth/booknest-jenkins (https://github.com/binarybehemoth/booknest-jenkins): the baseline plus Docker's Dockerfile and Compose 514 file, kept apart from GitHub's repository so that Jenkins 8,793 ' webhooks and status checks do not mix with its Actions workflows.

In New Item, name the job booknest-freestyle and choose Freestyle project. Restrict it to the label linux; under Source Code Management pick Git 1,932 , the repository URL and branch */main; under Triggers, Poll SCM with H/15 * * * * (H spreads jobs over the hour); add an Execute shell build step with the script in the figure; and Archive the artifacts booknest-*.tgz as a post-build action.

The Build Steps section of booknest-freestyle

Build Now starts it, and so does a POST to the job's build URL:

Starting the freestyle job and reading its logGroovy

J=http://localhost:32080; AUTH="admin:$JENKINS_TOKEN"
curl -s -u "$AUTH" -X POST $J/job/booknest-freestyle/build; sleep 25
curl -s -u "$AUTH" $J/job/booknest-freestyle/lastBuild/consoleText

Output

Finished: SUCCESS

This was the second build. The Git plugin exported GIT_COMMIT and GIT_BRANCH, and Jenkins BUILD_NUMBER. But look at the ls: build 1's tarball was still in the workspace, and the pattern archived it again. A freestyle job keeps its workspace unless you add a cleanup step.
