How to start/trigger a job when a new version of deployment is released (image updated) on Kubernetes?

I have two environments (clusters): Production and Staging with two independent databases. They are both deployed on Kubernetes and production doesn't have a fixed schedule for new deployments but it happens on a weekly basis (roughly).

I would like to sync the production database with the staging database every time that a new release is deployed to production (kubernetes deployment is updated with new image).

Is there a way that I can set a job/cronjob to be triggered everytime this even happen?

The deployments are done using ArgoCD to pull the changes in the deployment manifest from a github repository.

This is exactly the case what Argo Events is for.

There are many ways to implement this, but it depends on your exact situation how it’s best for you.

Eg. if you can use a Git tag event’s webhook you could go with an HTTP trigger to initiate a Job or Argo Workflow.

I think you can also use a tool like Kyverno and write a policy to generate a K8s job upon any resource created in K8s.

I don't think this functionality is inherent to kubernetes; you are asking about something custom that can be implemented in a variety of ways (depending on your tool stack)

e.g.

if you are using helm to install to Production, you can use a post-install hook that triggers a Job that does what you want.

Perhaps ArgoCD has some post-install functionality that can also create a Job resource doing what you want.
