Import and initialize modules​

Add dependencies​

Taking kawesome as an example, the directory structure is shown below:

example
├── dev
│   ├── example_workspace.yaml
│   ├── kcl.mod
│   ├── main.k
│   └── stack.yaml
└── project.yaml

Before importing modules in your AppConfiguration, you should add them to the dependencies part of the kcl.mod file.

[package]
name = "example"

[dependencies]
kam = { git = "https://github.com/KusionStack/kam.git", tag = "0.1.0" }
kawesome = { oci = "oci://ghcr.io/kusionstack/kawesome", tag = "0.1.0" }

[profile]
entries = ["main.k"]

The kam dependency represents the Kusion Application Module which contains the AppConfiguration and other basic modules. The kawesome is the Kusion module we are going to use in the AppConfiguration.

Initialize modules​

import kam.v1.app_configuration as ac
import kam.v1.workload as wl
import kam.v1.workload.container as c
import kawesome.kawesome as ks

kawesome: ac.AppConfiguration {
    # Declare the workload configurations. 
    workload: wl.Service {
        containers: {
            kawesome: c.Container {
                image: "hashicorp/http-echo"
            }
        }
    }
    # Declare the kawesome module configurations. 
    accessories: {
        "kawesome": ks.Kawesome {
            service: ks.Service{
                port: 5678
            }
        }
    }
}

Initialize the kawesome module in the accessories block of the AppConfiguration. The key of the accessories item represents the module name and the value represents the actual module you required.
