@Marvin, it has been a while since I've used Prefect. Last project I've done includes a prefect project described in the file

prefect.yaml

. Now looking at the docs, there is no mention of a prefect project concept. Has this concept been discontinued?

The concept of a Prefect project described using a

prefect.yaml

file persists in Prefect 2.x, but it has evolved with some significant changes. Here are the key points: 1. Initialization and Deployment Configuration: - You can initialize deployment configuration by running

prefect init

in any directory that stores your flow code, which creates the

prefect.yaml

file. - This YAML file now includes deployment configurations, instructions for building and pushing code artifacts, and instructions for pulling a deployment in remote execution environments. 2. Flexibility in File Location and Naming: - Unlike older versions where the

prefect.yaml

file had to be in the root directory and named precisely

prefect.yaml

, the newer version allows more flexibility. - The file can be located in different directories, including subdirectories, and can be named differently as long the filename ends with

.yaml

. 3. Deprecation and Migration Considerations: - Some features, such as the inability to use

deployment.yaml

in

prefect deploy

, have been deprecated in favor of a more unified approach. - Deprecated features will be retained for a certain period to ensure compatibility and allow for migration. For more details, you can refer to: - Prefect Deployment Guide - Prefect GCP Worker Guide - GitHub Issues discussing the usage and deprecation: - Issue discussing CLI deployment improvements - Issue regarding CLI deployment not working I hope this clarifies the current state of

prefect.yaml

and how it fits into Prefect 2.x. If you need further assistance, feel free to ask.
