nestjs cron job is not triggered

[mailhaim]

I've a nestjs cron job that runs OK locally but it is not triggered in GCP.  My code is delivered as docker. See the implementation below.
Any special service that I should activate or configuration I should do in GCP?
My Cron code:
 

@Cron(CronExpression.EVERY_DAY_AT_9AM)

  myCronMethod() {

    console.log("Called my cron method");

  }

Hi @mailhaim,

Welcome to Google Cloud Community!

Your NestJS cron job defined with @Cron(CronExpression.EVERY_DAY_AT_9AM) works locally but not on GCP when deployed as a Docker container.

Causes:

• Cron Expression: Double-check its accuracy. Use a validator online.
• Logging and Errors: Implement robust logging in myCronMethod and ensure logs are stored persistently in GCP.
• GCP Environment: Verify cron job registration in the container using crontab -l. Consider using Cloud Scheduler if you're on App Engine Flexible.
• Docker Image: Ensure the image has crontab installed.

Solutions:

• Follow troubleshooting steps: verify expression, check logs, debug in GCP.
• Test thoroughly after making changes.
• Consider using CI/CD for automated deployments.
