Subject: Add jenkins-init-scripts to global-jjb
X-Git-Tag: v0.21.0~27
X-Git-Url: https://gerrit.linuxfoundation.org/infra/gitweb?a=commitdiff_plain;h=d9aedddc8722e75fd24f9c7a9209e96ee5cea507;p=releng%2Fglobal-jjb.git

Add jenkins-init-scripts to global-jjb

These are the minion initialization scripts that start running
when our cloud plugin spawns a new minion. They are responsible
for prepping the minion for Jenkins to take over and run the job.

Issue: RELENG-994

+The files in this directory are for initializing a Jenkins minion just before
+the cloud plugin hands the minion over to Jenkins.
+
+init.sh is the entry point script which then calls all other scripts.
+
+init.sh also provides a local init script entry point by checking for the
+existance of the file CIMAN_ROOT/jenkins-init-scripts/local-init.sh. If this
+file exists it can be used to further customize the server node before handing
+it to Jenkins for job use.
+
+To use this create a managed file in Jenkins with the contents:
+
+    #!/bin/bash
+    git clone https://gerrit.example.org/r/ci-management.git /opt/ciman
+    /opt/ciman/jjb/global-jjb/jenkins-init-scripts/init.sh
