prefect-cloud

⚡ Deploy your code to Prefect Cloud in seconds! ⚡

Deploy and run your Python functions on Prefect Cloud with a single command.

Installation

First, install uv if you haven't already. See installation docs here

curl -LsSf https://astral.sh/uv/install.sh | sh

Create and activate a virtual environment:

uv venv && source .venv/bin/activate

Then install prefect-cloud:

uv pip install prefect-cloud

Alternatively, you can run prefect-cloud as a tool without installing it using uvx. See uv tools guide for more details.

Quick Start with uvx (no installation required)

If you prefer to run without installing, you can use uvx to run prefect-cloud commands directly:

# Login to Prefect Cloud
uvx prefect-cloud login

# Connect to GitHub (for private repos)
uvx prefect-cloud github setup

# Deploy your workflow
uvx prefect-cloud deploy examples/hello.py:hello_world --from PrefectHQ/prefect-cloud

# Run it
uvx prefect-cloud run hello_world/hello_world

# Schedule it
uvx prefect-cloud schedule hello_world/hello_world "0 * * * *"

Login to Prefect Cloud

prefect-cloud login

Deploy your workflow

Deploy any Python function from a GitHub repository. For example:

# https://github.com/ExampleOwner/example-repo-cloud/blob/main/examples/hello.py

def hello_world():
    print("Hello, World!")

Deploy to Prefect Cloud

prefect-cloud deploy <path/to/file.py:function_name> --from <source repo URL>

e.g.

prefect-cloud deploy examples/hello.py:hello_world --from PrefectHQ/prefect-cloud

Run it with

prefect-cloud run <flow_name>/<deployment_name>

e.g.

prefect-cloud run hello_world/hello_world

Schedule it with

prefect-cloud schedule <flow_name>/<deployment_name> <SCHEDULE>

e.g.

prefect-cloud schedule hello_world/hello_world "0 * * * *"

From a Private Repository

(Recommended!) Install the Prefect Cloud GitHub App into the repository you want to deploy from. This will allow you to deploy from private repositories without needing to provide a personal access token.

prefect-cloud github setup

Alternatively, you can provide a personal access token on each deploy:

prefect-cloud deploy ... --from <private source repo URL> --credentials GITHUB_TOKEN
