@Marvin what does this error mean when running prefect deploy --prefect-file prefect.yaml? “Discovered one or more deployment configurations, but no name was given. Please specify the name of at least one deployment to create or update.” I have names for each of the deployments and this works fine when I only have 1 deployment.

It seems like your deployment configurations are discovered, but the command does not know which specific deployment to create or update. This typically occurs when the

--name

parameter is not specified for

prefect deploy

. When you have multiple deployments defined, you must specify which one you want to deploy. Let me fetch information about using the

prefect deploy

command and how to properly specify deployment names when dealing with multiple deployment configurations. I'll search the Prefect documentation to get the most accurate and detailed information. Please hold on. To resolve the error, you need to specify the name of the deployment(s) you want to create or update. Here are a few ways to do that with the

prefect deploy

command: 1. Specify individual deployment names:

shell
   prefect deploy --name deployment-1 --name deployment-2

2. Using flow names to prefix deployment names:

shell
   prefect deploy --name my_flow/deployment-1 --name my_other_flow/deployment-1

3. Deploy all deployments:

shell
   prefect deploy --all

4. Deploy deployments matching a pattern:

shell
   prefect deploy -n my-flow/* -n *dev/my-deployment -n dep*prod

Here is an example

prefect.yaml

file illustrating multiple deployment configurations:

yaml
deployments:
  - name: deployment-1
    entrypoint: flows/hello.py:my_flow
    parameters:
      number: 42
      message: "Don't panic!"
    work_pool:
      name: my-process-work-pool
      work_queue_name: primary-queue
  - name: deployment-2
    entrypoint: flows/goodbye.py:my_other_flow
    work_pool:
      name: my-process-work-pool
      work_queue_name: secondary-queue

In summary, ensure you specify the deployment name(s) using the

--name

flag or use

--all

if you want to deploy all configurations. For more details, you can refer to this Prefect Deployment Guide.

@Marvin thanks, looks like I needed the

--all

flag.

I'm glad that helped. The

--all

flag is very convenient when you have multiple deployment configurations. If you have any more questions or run into any other issues, feel free to ask. Happy deploying! Here’s the relevant documentation link again for your reference.
