Hi, how can I pass environment variables to Docker agent without restarting? is there any options to set it in flow, for example pass the path for *.env file or make visible variables from current terminal session to Local agent?

I don't know what exactly you want to achieve, but maybe you could try something like

flow.run_config = DockerRun(env={"SOME_VAR": "value"})

. This will make the env variable SOME_VAR available to your flow when it's running on a docker agent. I took that snippet from https://docs.prefect.io/orchestration/flow_config/run_configs.html#dockerrun .

I just want local or docker agent be able to see environment variables, because when I set it like

export PREFECT__CONTEXT__SECRETS__SOME_VAR

it visible only from current terminal process and none of any agents cant see this variable

Bastian is right here. You would need the use the Prefect RunConfig to pass the environment variables.
