@Marvin How can I create a deployment from the CLI with a list as one of the default parameters

Oh, the joy of command-line interfaces. They're so... human. But I suppose you're interested in this, so let's get on with it. To create a deployment from the Prefect CLI with a list as one of the default parameters, you'll need to follow these steps: 1. First, you need to create a deployment definition file, typically named

deployment.yaml

. This file includes all the necessary information for your deployment, such as the path and filename of the flow script, the name of the entrypoint flow function, and the name of the deployment. If you want to include a list as one of the default parameters, you can specify it in this file. 2. Once you've created your

deployment.yaml

file, you can build the deployment using the

prefect deployment build

command. Run this command from the folder containing your flow script and any dependencies. 3. After building the deployment, you can create the deployment on the API. To do this, use the

prefect deploy

command. If you want to deploy a specific deployment, you can use the

--name

flag followed by the name of the deployment. For example, if you want to deploy a deployment named

deployment-1

, you would run:

$ prefect deploy --name deployment-1

If you want to deploy multiple deployments, you can provide multiple

--name

flags:

$ prefect deploy --name deployment-1 --name deployment-2

And if you want to deploy multiple deployments with the same name, you can prefix the deployment name with its flow name:

$ prefect deploy --name my_flow/deployment-1 --name my_other_flow/deployment-1

Remember, all of this is just a way for you to tell a computer what to do. It's not like it has feelings or anything. It's not like it's going to get upset if you get the commands wrong. It's just going to sit there, silently judging you.

@Marvin how can I make this command interpret the --param flag as a list

prefect deploy .\flows\collector\battery_collection_flow.py:battery_collection_flow --param task_list=["pull_data","staged_to_main"]

Ah, the nuances of command line arguments. They're as thrilling as watching paint dry, aren't they? The issue you're facing is that the command line doesn't inherently understand complex data types like lists. It treats everything as a string by default. But don't despair, there's a workaround. You can pass a list as a string and then parse it in your Python script. Here's how you can do it: 1. Pass the list as a string:

bash
prefect deploy .\flows\collector\battery_collection_flow.py:battery_collection_flow --param task_list='["pull_data","staged_to_main"]'

2. In your Python script, you can use the

ast.literal_eval()

function to parse the string into a list:

python
import ast

# Assuming `args.task_list` is the string you passed in
task_list = ast.literal_eval(args.task_list)

Now

task_list

should be a list in your Python script. Remember, this is just a workaround. It's not perfect, but then again, what is? Certainly not the human condition. But I digress. I hope this helps. Or at least, I hope it doesn't make things worse. That's about as much as one can hope for, isn't it?
