TeamCity - reboot dependency

README.md

To use:

1. Create a 'reboot' project with the reboot script in it. You'll need to encode the root password in the script so it can run shutdown, or otherwise arrange access to 'shutdown'.
2. Create a 'await reboot' project with the await script in it. Add the 'reboot' project as a snapshot dependency, that will mark the build as failed if it fails.
3. Add the plist to your /Library/LaunchAgent/ directory, or add the equivalent 'sed' script into your /etc/rc.local script for proper Unixes.
4. Add the 'await reboot' project as a dependency to your real build.

Dependent await reboot complete task

echo This task runs after the reboot task, as a buffer between the reboot script and the real reboot.
echo That is, THIS task will get all the INTERRUPTED errors, not the real scripts.

# Note: This script depends on the host machine's reboot process removing the 'rebooting=true' line from the buildAgent.properties
# See the plist in this gist, or add it to your rc.local.

echo Uptime:
uptime

echo Infinite loop until machine reboot, unless reboot is already complete:
while grep rebooting=yes $HOME/buildAgent/conf/buildAgent.properties; do
  echo $(date) Awaiting reboot to interrupt task and clear rebooting=yes from buildAgent.properties file.
  sleep 15
done

Main reboot task

echo "Adding system.rebooting=yes and rebooting=yes in properties, which now has..."

echo rebooting=yes >> $HOME/buildAgent/conf/buildAgent.properties
echo system.rebooting=yes >> $HOME/buildAgent/conf/buildAgent.properties
grep rebooting=yes $HOME/buildAgent/conf/buildAgent.properties

echo TEAMCITY_BUILD_PROPERTIES_FILE $TEAMCITY_BUILD_PROPERTIES_FILE

BUILD_ID=$(grep '^teamcity.build.id' $CONFIG_PROPERTIES | cut -d= -f2)
STATUS=$( echo "${TC_SERVER}/guestAuth/app/rest/builds/id:${BUILD_ID}" | tr -d \\ )

echo Polling $STATUS in background until parent task cannot be confirmed still running. Reboot will follow.
