Run One Time Tasks (Jobs)

[luxflux]

During our deployment, we have to run database migrations. How would you accomplish this with keel?
At the moment, we update the images in the deployments and run a Job which migrates the database.

We could accomplish this by locking the database and run the migration in an init container, but I'd rather to this explicit than implicit.

Hi, this will fit into plugins framework that I want to introduce into Keel. The idea is to have an option to register different plugins, examples of these plugins:

• run a custom code snippet downloaded from github/anywhere (can be limited to javascript or binary executables) or you could run a Keel derived from python, ruby images to have interpreters.
• run a k8s job
• call AWS lambda or Google Function endpoint

These plugins would take a json representation of the Deployment, could modify it, block update, cancel update or perform certain actions and then just let deployment update continue,

Yep, this would make our workflow possible.

I think there are now a lot better options like https://github.com/Azure/brigade to react to the events.
