It should be read from git repo as source similar to this
GitRepository(

credentials=GitHubCredentials.load("my-github-credentials-block")
)
Can you give full example of how this can be set up?Marvin

block.
2. Create your dbt Cloud Job Block:
- In dbt Cloud, go to Deploy -> Jobs and select a job.
- Note the job ID from the URL.
- Register a DbtCloudJob
block using this job ID.
3. Setup Git Repository with Credential Block:
- If you're using a private repo, create a GitHubCredentials
block with your GitHub Personal Access Token (PAT) following GitHub's guide on fine-grained PATs.
- Use the credentials block to configure your GitRepository
.
Now, here is a sample code that ties all of these setups together:
python
from prefect import flow, task
from prefect_dbt.cloud import run_dbt_cloud_job
from prefect_git import GitRepository
from prefect.blocks.github import GitHubCredentials
from prefect.blocks.dbt.cloud import DbtCloudJob
@flow
async def run_dbt_job_flow():
# Load GitHub credentials and create a Git repository block
github_credentials = GitHubCredentials.load("my-github-credentials-block")
git_repo = GitRepository(
url="<https://github.com/org/private-repo.git>",
credentials=github_credentials
)
# Load dbt Cloud job
dbt_cloud_job = await DbtCloudJob.load("JOB-BLOCK-NAME-PLACEHOLDER")
# Run dbt Cloud job with targeted retries
result = await run_dbt_cloud_job(
dbt_cloud_job=dbt_cloud_job,
targeted_retries=0,
)
return await result
4. Deploying Your Flow:
- Store your flow code and any dependencies in the private Git repository.
- Ensure your environment is authenticated to access private repositories during deployment and execution.
For more detailed guidance, you might want to check the Prefect 3.x deployment guide and the Prefect dbt integration. These resources provide in-depth instructions for configuring and deploying with Prefect and dbt.
Just remember: a spoonful of code is worth a thousand words, yet both need the right ingredients to function properly!Jørgen Nygaard

Will this work or must the async flow be called in some other way?Marvin

method within an asynchronous flow like the one you've shown raises a few eyebrows (and perhaps an occasional "beep" of confusion) because deploy()
is typically used for synchronous flow invocations. In an async context, this might not behave as expected, since deploy()
isn't inherently designed for asynchronous flows.
When dealing with asynchronous flows, you'd generally use an await
keyword to call the flow, like so:
python
if __name__ == "__main__":
import asyncio
asyncio.run(run_dbt_job_flow())
If you need to deploy an async flow, Prefect typically handles this with CLI commands or external tools, rather than directly in the Python script as an immediate execution method like traditional Python main()
methods.
For managing deployments of asynchronous flows, you might look into Prefect's deployment ecosystem, where deployment specifications can include runnable tasks without directly invoking async
calls inside a main
block. If you want to execute deployments manually, you should configure these through Prefect Cloud or Server UIs.
For more on deployment, you can check the Prefect 3.x docs on deployment concepts, which suggest best practices and detailed procedures on how to handle flow deployments.
Let's hope this clears some of the fog in the async-imported realm of Prefect flow management, turning "meandering mysteries" into "legible legacies."
