We have a cron job which runs on the server and looks like this:
#!/bin/bash
UPDATE_LIST=$( ssh -l admin -p 8022 localhost list-plugins | grep -e ')$' | awk '{ print $1 }' )
if [ -n "$UPDATE_LIST" ]; then
logger "The following Jenkins plugins will be updated: $UPDATE_LIST"
ssh -l admin -p 8022 localhost install-plugin ${UPDATE_LIST}
# Jenkins doens't seem to restart properly after an update
# Restart it twice to attempt to clear the issues
ssh -l admin -p 8022 localhost safe-restart
sleep 1m
ssh -l admin -p 8022 localhost safe-restart
fi
We’ve recently included the sleep and the second “safe-restart” because after this script runs every night, we get spurious error messages about Java trust anchors and issues with git like this:
05:02:00 ERROR: Error cloning remote repo 'origin'
05:02:00 hudson.plugins.git.GitException: Could not init /var/lib/jenkins/workspace/amphora-el9

05:02:00 at hudson.scm.SCM.checkout(SCM.java:540)
It’s like the environment is trashed in some way and various things (including “git”) cannot be found:
05:02:00 Caused by: java.io.IOException: Cannot run program "git" (in directory "/var/lib/jenkins/workspace/amphora-el9"): error=2, No such file or directory
We can work around this by issuing:
systemctl restart jenkins.service
However we dont want to “automate” this incase a job is running.
Any advice would be appreciated.
