Hi! I’m trying to run prefect server on virtual centos machine with custom .prefect/config.toml
Copy code
[server]

host = "ip"
port = "8081"
url = "https://${server.host}:${server.port}"

[ui]

host = "<http://ip>"
port = "8081"
host_port = "8081"
endpoint = "${ui.host}:${ui.port}"
And after checking prefect.config in python, I see my custom properties:
Copy code
<Box: {'debug': False, 'home_dir': '/home/o.ilinsky/.prefect', 'backend': 'server', 'server': {'host': 'ip', 'port': 8081, 'host_port': 4200, 'endpoint': 'ip:8081', 'database': {'host': 'localhost', 'port': 5432, 'host_port': 5432, 'name': 'prefect_server', 'username': 'prefect', 'password': 'test-password', 'connection_url': '<postgresql://prefect:test-password@localhost:5432/prefect_server>', 'volume_path': '/home/o.ilinsky/.prefect/pg_data'}, 'graphql': {'host': '0.0.0.0', 'port': 4201, 'host_port': 4201, 'debug': False, 'path': '/graphql/'}, 'hasura': {'host': 'localhost', 'port': 3000, 'host_port': 3000, 'admin_secret': '', 'claims_namespace': 'hasura-claims', 'graphql_url': '<http://localhost:3000/v1alpha1/graphql>', 'ws_url': '<ws://localhost:3000/v1alpha1/graphql>', 'execute_retry_seconds': 10}, 'ui': {'host': '<http://localhost>', 'port': 8080, 'host_port': 8080, 'endpoint': '<http://localhost:8080>', 'graphql_url': '<http://localhost:4200/graphql>'}, 'telemetry': {'enabled': True}, 'url': '<https://ip:8081>'}, 'cloud': {'api': 'ip:8081', 'endpoint': '<https://api.prefect.io>', 'graphql': 'ip:8081/graphql', 'use_local_secrets': True, 'heartbeat_interval': 30.0, 'check_cancellation_interval': 15.0, 'diagnostics': False, 'logging_heartbeat': 5, 'queue_interval': 30.0, 'agent': {'name': 'agent', 'labels': [], 'level': 'INFO', 'auth_token': '', 'agent_address': '', 'resource_manager': {'loop_interval': 60}}}, 'logging': {'level': 'INFO', 'format': '[%(asctime)s] %(levelname)s - %(name)s | %(message)s', 'log_attributes': [], 'datefmt': '%Y-%m-%d %H:%M:%S', 'log_to_cloud': False, 'extra_loggers': []}, 'flows': {'eager_edge_validation': False, 'run_on_schedule': True, 'checkpointing': False, 'defaults': {'storage': {'add_default_labels': True, 'default_class': 'prefect.environments.storage.Local'}}}, 'tasks': {'defaults': {'max_retries': 0, 'retry_delay': None, 'timeout': None}}, 'engine': {'executor': {'default_class': 'prefect.engine.executors.LocalExecutor', 'dask': {'address': '', 'cluster_class': 'distributed.deploy.local.LocalCluster'}}, 'flow_runner': {'default_class': 'prefect.engine.flow_runner.FlowRunner'}, 'task_runner': {'default_class': 'prefect.engine.task_runner.TaskRunner'}}, 'ui': {'host': '<http://ip>', 'port': 8081, 'host_port': 8081, 'endpoint': '<http://ip:8081>', 'graphql_url': '<http://ip:4200>'}}>
But server starts with localhost:8080 option:
Copy code
Visit <http://localhost:8080> to get started
And nothing on 8081 port. I also tried to set env
Copy code
export PREFECT__USER_CONFIG_PATH=/home/o.ilinsky/.prefect/config.toml
But it’s does’t work too. Do you know what I do wrong?) P.S. i’m new in prefect, so it may by stupid error :) ``````

Hi @Oleg - your config looks a little suspicious. For example the UI and Server (Apollo) ports are identical, which will mean one of them won't spin up (usually the UI). What's the setup you're trying to accomplish?

Hi. @nicholas The problem, which I’m trying to fix is localhost in web UI links. Prefect is running on virtual server. For example, link to graphql looks like http://localhost:4200 and I want to fix it. Also I’d like to use another port for UI. I fixed conf file:
Copy code
[server]

host = "my.ip"
port = "8080"
url = "https://${server.host}:${server.port}"

[ui]

host = "<http://my.ip>"
port = "8081"
host_port = "8081"
endpoint = "${ui.host}:${ui.port}"
graphql_url = "${ui.host}:${server.host_port}"
But still ui on 8080 port.
I’ve set ip of virtual machine in web UI and it fixed problem with localhost.

Hi @Oleg - does that mean you've got this figured out?
o
@nicholas, partially yes) but I can’t change UI port :)
