Create Project Resource
Resources are created with functions called constructors. To learn more about declaring and configuring resources, see Resources.
Constructor syntax

Project Resource Properties
To learn more about resource properties and how to use them, see Inputs and Outputs in the Architecture and Concepts docs.
Inputs
In Python, inputs that are objects can be passed either as argument classes or as dictionary literals.
The Project resource accepts the following input properties:
Outputs
All input properties are implicitly available as output properties. Additionally, the Project resource produces the following output properties:
- Endpoints Dictionary<string, string>
- Load
Balancer stringDns
- Endpoints map[string]string
- Load
Balancer stringDns
- endpoints map(string)
- load_
balancer_ stringdns
- endpoints Map<String,String>
- load
