@Marvin how can i select a python virtualenv for a deployment
m
To select a Python virtual environment for a Prefect deployment, you will need to use the
run_shell_script
step to activate the virtual environment within your deployment configuration. Below is an example: 1. Create and configure your virtual environment:
Copy code
shell
   python -m venv myenv
   source myenv/bin/activate  # On Windows, use: myenv\Scripts\Activate.ps1
   pip install -r requirements.txt
2. Deploy your flow with the virtual environment:
Copy code
yaml
   pull_steps:
     - prefect.deployments.steps.run_shell_script:
         id: activate-venv
         script: source myenv/bin/activate  # On Windows, use: myenv\Scripts\Activate.ps1
         stream_output: true
This will ensure that your deployment activates the virtual environment before executing further steps. For more detailed information, you can refer to the Prefect Deployment Guide. If you encounter issues or need additional examples, see related GitHub discussions: - Database QueuePool issue with large task flows: https://github.com/PrefectHQ/prefect/issues/6492 - Problems creating a working KubeClusterConfig from the Blocks page: https://github.com/PrefectHQ/prefect/issues/8640

@Marvin is remote signed needed?
m
The documentation does not explicitly mention that remote signing is required for deployments. If you are referring to the need for signed code or configurations for security purposes, this is usually dependent on your organization's policies rather than a requirement from Prefect itself. For more details on deployment and configurations, you can check the Prefect Deployment Guide: - Prefect Deployment: https://docs.prefect.io/latest/guides/prefect-deploy/ - Push Work Pools: https://docs.prefect.io/latest/guides/deployment/push-work-pools/ If you have any specific security requirements or concerns, you'd best consult with your organization's security policies.
