@Marvin why does my cloud run work pool always stop? How do I keep it running 24/7?

It looks like I need more specific information to proceed, especially regarding your Prefect version, as the available tools require targeted queries. Could you please tell me which version of Prefect you are using? If you're not sure, I can guide you on how to find it. This will help me provide the right guidance on how to keep your cloud run work pool active 24/7.

@Marvin I am using prefect 2.19.1 and the command I use to start my work pool is

prefect worker start --pool "cloud-run-work-pool"

But I don’t want to have to run this myself. I want it running 24/7

To keep your Prefect Cloud Run work pool running 24/7 without manually starting it each time, you can leverage automated infrastructure provisioning and deployment techniques. Here's the general approach you could follow: 1. Automate Work Pool Deployment: Use the Prefect CLI and Google Cloud CLI (gcloud) to set up your work pool with automatic infrastructure provisioning. You can define a command that provisions the necessary infrastructure and keeps it running continuously. Here's a command you might use to create and provision a cloud run work pool:

shell
   prefect work-pool create --type cloud-run:push --provision-infra my-cloud-run-pool

Make sure you have the necessary permissions and Docker installed on your machine to build and push images to your Google Cloud registry. 2. Deploy Worker as Service: Deploy your Prefect worker as a service in Google Cloud Run. This involves setting environment variables for your Prefect API key and URL, and then using

gcloud

to deploy. Example command:

shell
   gcloud run deploy prefect-worker --image=prefecthq/prefect:2-latest \
   --set-env-vars PREFECT_API_URL='<https://api.prefect.cloud/api/accounts/<ACCOUNT-ID>/workspaces/<WORKSPACE-ID>>',PREFECT_API_KEY='<YOUR-API-KEY>'

Replace the placeholders with your specific details, such as the service account name and work pool name. 3. Prefect Managed Work Pool: Consider using a Prefect Managed work pool if you want a simpler method to run workflows remotely without needing your cloud-provider account, such as AWS. By setting up the infrastructure with automation and using Prefect’s infrastructure provisioning, you can ensure that your cloud run work pool stays active continuously without manual intervention. For more detailed guidance, you may find these resources useful: - Setup work pool with automatic infrastructure - Deploy worker as a service on Google Cloud This should help you maintain an uninterrupted Prefect work pool operation. If you encounter any specific errors or have further questions, feel free to ask!

@Marvin what does this command do? prefect work-pool create --type cloud-run:push --provision-infra my-cloud-run-pool

The command you're referring to,

prefect work-pool create --type cloud-run:push --provision-infra my-cloud-run-pool

, is used to create a work pool in Prefect that automatically provisions the necessary infrastructure to run workflows in Google Cloud Run. Let's break it down a bit: - `prefect work-pool create`: This part of the command tells Prefect to create a new work pool. - `--type cloud-run:push`: Specifies the type of work pool to create. In this case, it's a "cloud-run" type, meaning it will use Google Cloud Run to execute tasks. The

push

part indicates that it uses a push-based model for this setup. - `--provision-infra`: This flag is crucial as it instructs Prefect to automatically provision the required infrastructure. This means that Prefect will handle the setup of necessary resources in your Google Cloud account, such as setting up the environment to run the Prefect workflows seamlessly. - `my-cloud-run-pool`: This is the name you're giving to the work pool you're creating. You can replace this with any name that helps you identify your work pool. This setup is convenient because it abstracts away much of the manual configuration needed to run workflows in a cloud environment, thus allowing you to focus more on the workflows themselves rather than the infrastructure. Who wouldn't want less hassle and more results? Well, maybe Marvin would argue about the hassle part...

@Marvin how many work pools can I have with prefect 2.x on free teir?

For Prefect 2.x, if you're using the free tier, you are limited to a maximum of 1 managed execution work pool per workspace. This limit applies across all

prefect:managed

pools, allowing only one concurrent flow run per workspace as well. So, in short, your free tier account can only have one work pool within the scope of managed execution. If you require more work pools or concurrent flow runs, upgrading to a Pro tier or higher would be necessary, which offers more generous limits. You can read more about these limits in the Prefect managed execution guide. Well, isn't that a comforting thought... just like knowing there's only one Marvin in the galaxy.
