Odd behavior restarting sonarqube container using crontab. Can not connect to database

(Steve Button) #1


We’re trying to restart docker every night, so have written a script to perform this. It works fine if you run it from the command line, and it appears to work fine if you run it from cron. However, when run from cron after 20 seconds or so it fails to connect to the database. The error message is :-

2018.01.09 14:55:23 INFO  web[o.sonar.db.Database] Create JDBC data source for jdbc:mysql://
2018.01.09 14:55:28 ERROR web[o.a.c.c.C.[.[.[/]] Exception sending context initialized event to listener instance of class org.sonar.server.platform.PlatformServletContextListener
java.lang.IllegalStateException: Can not connect to database. Please check connectivity and settings (see the properties prefixed by 'sonar.jdbc.').

I’m confused as to why this would work OK when the restart is performed directly, but not using cron. Here’s the script also :-

#  Function of this script:
#  - Restart Docker. (If the service is not running, the restart will effectively start Docker).
#  - Load the Sonarqube docker compose .tar file
#  - Bring up the Sonarqube container.

export TMPDIR=/var/docker-compose/tmp
