The transition to Prefect 3.x brings a more elegant approach to deployment creation. Here's what you need to know: 1. Instead of

prefect deployment build

, you now use

prefect deploy

2. The new system revolves around a

prefect.yaml

configuration file that defines your deployment settings Here's a quick example of how it works:

yaml
# prefect.yaml
deployments:
  - name: my-deployment
    entrypoint: flow.py:my_flow  # path to your flow function
    schedule: null  # or define a schedule
    work_pool: 
      name: my-work-pool

Then simply run:

bash
prefect deploy

This new approach is more powerful and flexible than the old

build

command because: - It provides a clear, version-controlled configuration - It handles both building and pushing in one step - It supports more advanced configuration options through the YAML file You can find complete details in the documentation: - Prefect YAML Guide - Deployments Concept Guide Would you like me to explain any specific aspect of the new deployment system in more detail?
