Knative Workflow Tips

Quick recommendations and tips for various processes.

Development Workflow

  1. Write your functions
  2. Use serverless deploy when you've made changes to serverless.yml and in CI/CD systems.
  3. Use serverless invoke -f myFunction to test your functions on Knative.
  4. Write tests to run locally.

Using stages

  • At the very least, use a dev and prod stage.
  • In larger teams, each member should use a separate Knative installation and their own stage for development.

Larger Projects

  • Break your application / project into multiple Serverless services.
  • Model your Serverless services around data models or workflows.
  • Keep the functions in your Serverless services to a minimum.
