@Marvin how would you authenticate to the cloud when building a worker agent using the official image prefecthq/prefect:2-python3.11? can you pass env vars into the container itself or some other way?

To authenticate a worker in Prefect Cloud using the official image

prefecthq/prefect:2-python3.11

, you can pass environment variables into the container. Specifically, you'll need to set the following environment variables: - `PREFECT_API_URL`: Set this to the API URL of your Prefect Cloud instance, such as

<https://api.prefect.cloud/api/accounts/<ACCOUNT-ID>/workspaces/<WORKSPACE-ID>>

. Replace

<ACCOUNT-ID>

and

<WORKSPACE-ID>

with your actual account and workspace IDs, which you can locate in the UI's dashboard URL. - `PREFECT_API_KEY`: Use an active API key here. Here's an example of how to set these environment variables before running a command to deploy your worker:

bash
export PREFECT_API_URL='<https://api.prefect.cloud/api/accounts/<ACCOUNT-ID>/workspaces/<WORKSPACE-ID>>'
export PREFECT_API_KEY='<YOUR-API-KEY>'

Afterwards, you can launch your worker with a command like the following, replacing necessary placeholders:

bash
gcloud run deploy prefect-worker --image=prefecthq/prefect:2-latest \
  --set-env-vars PREFECT_API_URL=$PREFECT_API_URL,PREFECT_API_KEY=$PREFECT_API_KEY \
  --service-account <YOUR-SERVICE-ACCOUNT-NAME> \
  --no-cpu-throttling \
  --min-instances 1 \
  --args "prefect","worker","start","--install-policy","always","--with-healthcheck","-p","<WORK-POOL-NAME>","-t","cloud-run"
