Hi everyone, I'm new to Prefect and assume it will be a great product to use once I actually have it working. Thank you for all the effort you've put into it, and for making it free to evaluate effectively. I'm attempting to integrate Prefect into an existing docker-compose development environment. Running

prefect server start

yields a functional deployment with a working dashboard, but calling

docker-compose up

on the

docker-compose.yml

produced by executing

prefect server config

does not (the UI is responsive, but the dashboard pane below the top nav bar is blank). Also, any attempt to start a local agent in an adjacent docker container gives me a "No tenant found" message via a ClientError exception. Is the

prefect server config

command not actually producing everything it should be at present? I'm sure I can manually build a functional docker-compose.yml by reviewing the prefect docker-compose wrapper, but that might be very time-consuming, so I'm hoping the problem is just something simple that

prefect server config

is leaving out. I'm going to be evaluating the two deployments back to back now to see if I can tell what's missing. Any ideas would be greatly appreciated. Thanks again!

Hey @Nate Jahncke --

prefect server start

creates the default tenant for you but spinning up your own does not 🙂 you'll just need to run

prefect server create-tenant -n default

So wait, you're telling me I need to connect my local docker-compose environment to the Prefect cloud in order to use it?

Nope you just need to insert a tenant into the prefect server database

Hey thanks for your help btw.

Run

prefect backend server

🙂

Yeah, as I mentioned I'm really trying to run all this stuff without using the prefect module wrapper, as I have a number of other services to integrate it with. It doesn't really make sense to me to run some things via docker-compose.yml, and prefect using its own special program.

So you can take a look at the backing function for this and just use

curl

to hit the graphql api instead. The mutation used is at https://github.com/PrefectHQ/prefect/blob/master/src/prefect/client/client.py#L111

Ah ok perfect, I think that's exactly what I was looking for! Thanks for your help 🙂

Also perhaps helpful as a reference, the Helm chart uses a K8s job to run the tenant creation https://github.com/PrefectHQ/server/blob/master/helm/prefect-server/templates/jobs/create_tenant.yaml

Great, that's helpful, thank you. I'll be doing something similar in my agent container.

That could definitely do it. It's also your database so you can just run SQL to insert a tenant if you wanted. Lots of options here.

I think I was just missing a piece of info because my (obviously false) understanding was the client was required only for cloud connections. Lots of banging my head against the desk today lol.

@Marvin open "`prefect server config` does not include instructions on tenant creation"

👍

Right. We'll definitely eventually move that route if things work out. There was one other issue I think you might want to make a note of. Should I write it here or do you want me to submit an issue myself? Happy to if that's better.

I might have the answer but if it's long form an issues are easier to track I'll see it either way.

Actually nope, it was part of the other problem apparently. URL resolution issue I thought was due to a parsing problem. I'm completely up and running! Thanks a lot Michael.

Sweet -- what did you end up doing for tenant creation? (trying to survey the most convenient option here)

Oh I thought originally that would need to happen from outside the container environment, which is why I was concerned about it, but now I just use the prefect module from within the agent container before running the actual agent. On startup it just pipes the result of a curl query through jq to see if there's an existing tenant and creates one if not. Not really a necessary extra step, but I hate having exceptions in my logs even if they're expected. I'm really looking forward to digging into this stuff this weekend, so thanks again for getting me unstuck! I'm sure that extra bit of info around the tenant role when using

prefect server config

will be very helpful for the next person that stumbles across it like I did.
