@Marvin In Prefect 3, how do I deploy prefect deployments automatically with CI/CD ?a We can see deployments definition on

prefect.yaml

, but the deployments are not separated each other. My CI/CD pipeline could not detect what the code of deployments are changed. I think deploy all deployments all-time is not good idea. Could I define my deployments into separated file each ? e.g. •

prefect.yaml

can include other files

deployment1.yaml

and

deployment2.yaml

• If I changed codes in

deployment1.yaml

, my CI/CD pipeline recognize what deployment to Deploy.

In Prefect 3, you can indeed create separate deployment configuration files to make your CI/CD pipeline more manageable. Here's how you can handle deployments separately and have your CI/CD recognize changes: 1. Separate Deployment Files: You can create multiple

prefect.yaml

files located in different directories. Each file can define distinct deployments. This is possible because, in Prefect 3, the

prefect.yaml

file can reside outside the project's root directory or inside subdirectories, and you can have multiple files with the same name in different directories. 2. Using the

--prefect-file

Argument: When deploying, you can specify which deployment file to use by using the

--prefect-file

CLI argument. This allows you to target specific deployment configurations: - For example, if you have

deployment1.yaml

and

deployment2.yaml

, you can deploy them individually with:

prefect deploy --prefect-file path/to/deployment1.yaml

or

prefect deploy --prefect-file path/to/deployment2.yaml

3. Detecting Changes in CI/CD: Since your deployment configurations are separated, your CI/CD pipeline can be set up to watch for changes in specific deployment files and only deploy the affected configurations. This way, you avoid the inefficiency of deploying all configurations every time. Here's a useful source to get you started on configuring these separate deployment files: Prefect Documentation on Deployment Files. So, if your pipeline detects changes to

deployment1.yaml

, it would only re-deploy

deployment1

and not touch

deployment2

. That should keep your deployments as efficient as possible!

@Marvin Yo great! I didn't know I could have two or more prefect.yaml. btw is there any way inherit work-pool definitions in my prefect.yaml to another one if I separate prefect.yaml ?

Currently, in Prefect 3, there is no direct mechanism to inherit or share work-pool definitions across multiple

prefect.yaml

files. Each yaml file operates independently in terms of its configurations, including work-pool settings. However, here are some strategies you might consider: 1. Consistent Naming Conventions: You can ensure that each

prefect.yaml

file uses the same naming conventions for work-pools, thus manually "syncing" their configurations. Any change made will have to be manually replicated across the files, but it maintains consistency. 2. Scripting Configuration Updates: You could create a script that updates all your

prefect.yaml

files with a common configuration template for work pools. This script could be part of your CI/CD process, ensuring each configuration file remains consistent with your desired setup. 3. Environment Variables: If certain aspects of your work-pool configuration are dynamic or environment-specific, consider using environment variables within your yaml configuration. This allows for more flexible deployment environments without the need for maintaining multiple distinct configurations. For more insights on how work pools function and their conceptual framework, you might find this Prefect documentation on work pools helpful. Remember, while there's no inheritance, creativity with scripting and standardized patterns can keep you efficient!

@Marvin I figure that. thank you!

You're welcome! If you have any more questions, feel free to ask. Just remember, in the world of CI/CD, creativity and consistency are your best friends. Good luck with your Prefect deployments! 😊
