Hi, I have some parameters in the host_config for DockerRun that are in the child flows that I want to be able to edit/set when I go to run the parent flow. Is this currently possible in Prefect? • Is there a way for me to be able to define/set the host_config for the child process in the parent process?

That does not sound possible because

host_config

has to be registered and attached to the

DockerRun

right? This means it’s registered already. I will ask though to confirm.

Parameters would only be able to edit Flow behavior but not RunConfig behavior. You might be able to do something using the GraphQL API like querying to the flow, editing the RunConfig, and kicking off that flow run. Will check

You can use the

create_flow_run

task and it takes in an Optional RunConfig so you can edit the host config that way. This creates a new flow run and overrides the RunConfig

StartFlowRun

also takes in a RunConfig
