@Marvin How should i set auth string on prefect client? I want run deploy function to send script for be run on worker

To set the authentication string on the Prefect client and deploy a script to be run on a worker, you need to configure your API key and URL as environment variables. Here's a concise guide: 1. Set Environment Variables: You need to set

PREFECT_API_URL

and

PREFECT_API_KEY

in your environment. This can be done in your terminal like this:

bash
   export PREFECT_API_URL='<https://api.prefect.io>'
   export PREFECT_API_KEY='<YOUR-API-KEY>'

Replace

<YOUR-API-KEY>

with your actual API key. More details can be found in the Prefect settings and profiles documentation. 2. Deploy Function: Use the

deploy

function from Prefect to send the script to the worker. The function is available at the top level of the Prefect API. Ensure your environment is correctly set up before running this function. For more detailed steps, especially if you're using specific integrations like Google Cloud, you can refer to the GCP Worker Guide. If you need further assistance with specific commands or configurations, feel free to ask.

@Marvin I have self-hosted server, so i don't need api key, but rather basic authentication

For a self-hosted Prefect server with basic authentication, you'll need to configure your client to connect using the server's API URL. Here's how you can set it up: 1. Set the API URL: In your terminal, set the

PREFECT_API_URL

environment variable to point to your self-hosted server instance. For example:

bash
   export PREFECT_API_URL='<http://your-prefect-server-url>'

2. Basic Authentication: Prefect doesn't natively support basic authentication directly through environment variables. However, you can configure your reverse proxy (e.g., Nginx or Traefik) to handle basic authentication for you. This means you would set up basic authentication at the proxy level and ensure that traffic to your Prefect server goes through this proxy. 3. Profiles and Configuration: You can save the API server address in a Prefect profile. Whenever that profile is active, the API endpoint will be used at that address. More details about profiles can be found in the Prefect settings and profiles documentation. For more details on self-hosting and configuring a Prefect server, refer to the self-host documentation. If you have more specific configurations or need further assistance, let me know!

@Marvin documentation mentions this:

api.auth_string="admin:pass"

: this setting should be set with the same administrator / password combination as the server on any client process that needs to communicate with the Prefect API (for example, any process that runs a workflow).

It seems the documentation you referred to is not directly accessible or detailed in the current search results. However, based on your mention, it appears that you can set the

api.auth_string

directly on the Prefect client to handle basic authentication for a self-hosted server. Here's how you can set it: 1. Set

api.auth_string

: You can configure the Prefect client to use basic authentication by setting the

api.auth_string

in your script or configuration. This should be done with the same administrator/password combination as your server. Here's an example:

python
   from prefect import get_client

   client = get_client()
   client.api.auth_string = "admin:pass"

2. Ensure the Server is Configured: Make sure your self-hosted server is set up to accept basic authentication with the credentials you are using. 3. Environment Configuration: If you are using environment variables or a configuration file, ensure that they are correctly set up to utilize this authentication method.
