I'm try to using kcl to manage kind config files and have not get the | from kubeadmConfigPatches.

$ kcl main.k 
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
networking:
  apiServerAddress: '127.0.0.1'
nodes:
- role: control-plane

2. What did you expect to see? (Required)

$ kcl main.k 
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
networking:
  apiServerAddress: '127.0.0.1'
nodes:
- role: control-plane
  image: kindest/node:v1.30.0
  kubeadmConfigPatches:
  - |
    kind: ClusterConfiguration
    apiServer:
      extraArgs:
        runtime-config: api/all=true 
        storage-media-type: application/json
...

I'm not sure kcl does support this case? remind me if i missed something,Thanks.

3. What did you see instead (Required)

4. What is your KCL components version? (Required)

Hello @liangyuanpeng Perhaps what you want is this piece of code.

kind = "Cluster"
apiVersion = "kind.x-k8s.io/v1alpha4"
networking = {
     #https://kcl-lang.io/docs/user_docs/support/faq-kcl#39-how-to-set-default-value-for-option-function-in-kcl
    apiServerAddress = option("apiaddress",default="127.0.0.1")
}
nodes=[{
        role = "control-plane",
        image = option("kindimage",default="kindest/node:v1.30.0")
        kubeadmConfigPatches = [
"""\
kind: ClusterConfiguration
apiServer:
  extraArgs:
    runtime-config: api/all=true
    storage-media-type: option("storageMediaType",default="application/json")
"""
        ]
}]
qqq="""\
kind: ClusterConfiguration
apiServer:
  extraArgs:
    runtime-config: api/all=true
    storage-media-type: option("storageMediaType",default="application/json")
"""
qqq2="""\
hello
"""

Please note that my additional task is to remove trailing spaces in multiple line strings

[liangyuanpeng]

@Peefy Awesome!! Thanks for quickly reply, and do you want to support set param on multiple line strings? I'm not sure if this is a reasonable request. Anyway, now it does what I want.

kind = "Cluster"
apiVersion = "kind.x-k8s.io/v1alpha4"
networking = {
     #https://kcl-lang.io/docs/user_docs/support/faq-kcl#39-how-to-set-default-value-for-option-function-in-kcl
    apiServerAddress = option("apiaddress",default="127.0.0.1")
}
nodes=[{
        role = "control-plane",
        image = option("kindimage",default="kindest/node:v1.30.0")
        kubeadmConfigPatches = [
"""\
kind: ClusterConfiguration
apiServer:
  extraArgs:
    runtime-config: api/all=true
    storage-media-type: ${REALLY_STORAGE_MEDIA_TYPE}
"""
        ]
}]

run command with:

REALLY_STORAGE_MEDIA_TYPE=application/json envsubst < main.k > main2.k
kcl main2.k
