101 Lab 🧑‍🔬 👩‍🔬 Use Open-Meteo API • Authenticate your CLI to Prefect Cloud • Fine to use a personal account or a workspace • Write flow code that fetches other weather metrics • Make at least 3 tasks • Use .serve() method to deploy your flow • Run your flow from the UI and CLI • Example: windspeed for the last hour: _weather.json()["hourly"]["windspeed_10m"][0]_ • Docs: open-meteo.com/en/docs

Post your code for the 101 Lab in this thread 🙌 🧵

FYI - if you’re on Windows and having trouble with

prefect cloud login

try

pip install python-certifi-win32

is this error happening to anyone??:

Lab 102 🧑‍🔬 👩‍🔬 • Use your flow that grabs weather data from open-meteo • Add retries • Run your flow • Inspect in the UI • Stretch: create an artifact • Stretch: add caching

Post your code for the 102 Lab in this thread 🙌 🧵

Bringing in everyone in 4 min!

103 Lab 🧑‍🔬 👩‍🔬 • Make an email notification automation for any flow run completion • Run a flow a few times from the CLI • See the event feed in the UI • Stretch: create a custom event - run it and see the event in the UI

@Luis Martínez - more on live reloading in this 🧵

Looking forward to seeing you all tomorrow, great job today!

Hey y’all 👋 recording from day 1 is in this thread 🧵

Slides for day 2

Lab 104 Instructions 🧑‍🔬 👩‍🔬 > Use a flow from the 103 lab > • Make a deployment via interactive CLI commands > • Start a worker > • Run the deployment > • See the flow run logs in the UI > • Stretch: Create a deployment that has default parameters & override the default parameters at runtime

1-5 Lab 👩‍🔬 🧑‍🔬

• Create a deployment that uses a subflow.

• Use GitHub or other git-repo-based code storage.

◦ Don’t forget to push your code!

• Check out the prefect.yaml file.

• Add a cron schedule.

• Pause the schedule.

• Stretch: Create a second deployment that uses _run_deployment_

• Super stretch: Create a webhook and automation that runs a deployment in response to an event firing

@Lily Grier - FYI, I filed this issue to fix the behavior you were seeing.

Here’s the recording from today 🧵

Hey prefect team. I just got my accredible badge! thank you very much. But I have a problem, is there anyone that could help me?

Hey all! 👋 Way to rock it! 🎸 If you attended PACC you should have received your certification via email from Accredible. Please DM me if you have any issues. Thank you for everyone who filled out the brief feedback form. If you haven’t yet, please take two minutes to let us know what went well and what could be improved. 🦜
