I started in local k8s
got ui, server. apollo, postgres and hasura up and running
prefect-ui              : <http://localhost:30562/>           # works
prefect-server          : <http://localhost:31722/graphql/>   # works
prefect-apollo          : <http://localhost:30524/graphql>    # works
graphql-engine (hasura) : <http://localhost:32078/console>    # works

Okay then you probably need to create a default tenant for the server (it is created by default when using the standard docker-compose setup). Try running: 
prefect server create-tenant -n default

Which version of Prefect / the server are you running?
v

Vitaly Shulgin

09/09/2020, 7:20 PM
0.12.6

Ah that makes sense as to why tenant is not found. Try upgrading to a version above 
0.13.0
(the most recent version is 
0.13.6
). This error suggests that you’re using a version of Prefect newer than when the server project was migrated over into a separate repo 🙂

ok, thanks, I'll try with updated versions
switched to 0.13.6, created tenant and project
what about 
+ prefect-server services scheduler
Usage: prefect-server services [OPTIONS] COMMAND [ARGS]...
Try 'prefect-server services --help' for help.

Error: No such command 'scheduler'.
there was separate scheduler container, now it looks like such configuration is obsolete, and this command not supported

Ah the scheduler and some other newer services were bundled into a new service called 
towel
😅 here’s some information on the newer architecture pattern https://docs.prefect.io/orchestration/server/architecture.html

Vitaly Shulgin

09/09/2020, 9:38 PM
yes, got it started as towel
last piece in puzzle
agent is running
but does not start any job

What do you see in the agent logs?

Check to make sure you don’t have any extra labels on your flows when registering them. For more information: https://docs.prefect.io/orchestration/execution/overview.html#labels

thanks, it works now
unfortunately, the job itself (or task run) failed
Last State Message
[10 Sep 2020 1:07am]: Failed to load and execute Flow's environment: FileNotFoundError(2, 'No such file or directory')
the simplest one
import prefect
from prefect import task, Flow
from prefect.environments import LocalEnvironment

@task
def hello_task():
    logger = prefect.context.get("logger")
    <http://logger.info|logger.info>("Hello, Cloud!")

flow = Flow("hello-flow", tasks=[hello_task])
flow.environment = LocalEnvironment(labels=["any"])
flow.register(project_name="Hello")
container image was 
prefecthq/prefect:all_extras-0.13.5
not sure, why, but this is another question
anyway, thanks for support
