@Marvin I create deployment, but it's not showing up in the Prefect UI

Could you please clarify which version of Prefect you are using? Prefect 2.x and 3.x have different interfaces and functionalities.

Using Prefect 3, I'm deploying by running a python script in a Docker Container

It seems there are some known issues in Prefect 3 regarding deployments not appearing in the UI. Here are a few possibilities based on recent GitHub issues: 1. Endless Loop in Backend: One issue highlighted involves an endless loop happening in the backend, where after several manual script executions, workflows stop displaying correctly in the UI. Restarting the Prefect server may resolve the issue temporarily. More details can be found in the issue here. 2. Schedules Missing: Another issue noted was that schedules were missing on the deployment page, related to a

TypeError

. While this doesn’t directly affect all deployments showing, it might relate to UI display issues for specific elements in a deployment. Check out the discussion here. 3. Task Scheduling Problems: When using task runners like Dask, there might be issues with scheduling that can ultimately lead to flow execution but not updating UI elements correctly. Details about this can be found here. To troubleshoot, here are a few steps you can try: - Ensure that your Prefect servers are running smoothly and consider restarting them if you encounter display issues. - Verify that your deployment script is correctly setting all necessary parameters and your environment is correctly configured. - Check the Prefect server logs for any errors or warnings that might point to connectivity or internal server issues. If these suggestions don't solve the problem, consider reaching out on Prefect's community support channels or their GitHub repository to report new issues or find further assistance. Hopefully, this helps you figure out why your deployment isn't showing up. Let me know if these steps resolve the issue!

@Marvin I add deployment by running Python Script with Serve, but deployment is not showing up in Prefect UI, but it actually executes it

It looks like your deployment is executing but not showing up in the Prefect UI, and there are a few potential reasons this could happen. 1. UI Refresh or Sync Delay: Sometimes the UI may have a delay in refreshing. Ensure you've refreshed the UI or check back in a few minutes to see if the deployment appears. 2. Correct Tagging: When using the

serve

method, make sure you apply the correct tags. These tags are often used for bookkeeping and filtering purposes in the UI. Here's an example snippet:

python
   hello_world.serve(name="my-first-deployment",
                     tags=["onboarding"],
                     parameters={"goodbye": True},
                     pause_on_shutdown=False,
                     interval=60)

3. Work Queue and Pool Configuration: Ensure that your deployment is correctly associated with a work pool and queue in your configuration (

work_pool_name

and

work_queue_name

). This is necessary for Prefect to correctly schedule and track deployments. 4. Deployment YAML File: Verify that your deployment's

prefect.yaml

file is correctly set up with all necessary fields and that no errors occur during the

prefect deploy

command. Here's a link to more about configuring deployments: Infrastructure Concepts. 5. Network or Environment Issues: Sometimes, networking issues can cause delays or visibility problems in the UI. Check if there are any connectivity issues between your environment and the Prefect server. 6. Prefect Server Logs: Check the Prefect server logs for any warnings or errors. Sometimes, this can provide more insight into what's going wrong. If you've tried these suggestions and the issue persists, consider reaching out on the Prefect community forums or filing a detailed issue on their GitHub page. This can help Prefect’s team provide more targeted assistance.

@Marvin I'm using Serve on Prefect 3, it's still not showing up on Prefect UI, even though it's running in the background

It seems like you're encountering an issue where your deployment runs successfully but doesn't appear in the Prefect UI. Based on recent open issues and discussions on GitHub, this could be related to certain backend or UI synchronization problems. Here are a few insights from the issues tracker: 1. Endless Loop and Backend Issues: One known issue is that the backend may get into an endless loop, leading to a situation where workflows stop displaying correctly in the UI. Restarting the Prefect server might temporarily resolve the problem. You can check more about this issue here: Endless Loop Symptoms on Prefect Server. 2. Deployment Not Reflecting in UI: There might be situations where deployments might not reflect due to internal state inconsistencies or database conflicts, as seen in the logs from some users. 3. Configuration and Setup: Ensure your Prefect environment is correctly configured, particularly if you're running deployments with

serve

. Double-check that all properties for your deployments are set correctly and there's no version mismatch causing this within docker containers or when interfacing with the Prefect server. Given these insights, here are some potential steps to troubleshoot: - Restart your Prefect server and monitor any logs for unusual activity. - Ensure that your UI and backend services are fully operational and updated to compatible versions. - Check your deployment script to ensure that all requisite configurations (tags, name, work pool, etc.) are correctly applied. - Look at Prefect server logs for any indications of errors or warnings. If these checks do not resolve the issue, you might want to follow up directly with the Prefect community or file a detailed report on their GitHub repository for more targeted assistance.
