/**
The following parameters could be either a plain text, or referenced to a secret in a keyvault:
- apiServerCertificate
- apiServerPrivateKey
- caCertificate
- clientCertificate
- clientPrivateKey
- kubeConfigCertificate
- kubeConfigPrivateKey
- servicePrincipalClientSecret
- etcdClientCertificate
- etcdClientPrivateKey
- etcdServerCertificate
- etcdServerPrivateKey
- etcdPeerCertificates
- etcdPeerPrivateKeys
To refer to a keyvault secret, the value of the parameter in the api model file should be formatted as:
"<PARAMETER>": "/subscriptions/<SUB_ID>/resourceGroups/<RG_NAME>/providers/Microsoft.KeyVault/vaults/<KV_NAME>/secrets/<NAME>[/<VERSION>]"
where:
<SUB_ID> is the subscription ID of the keyvault
<RG_NAME> is the resource group of the keyvault
<KV_NAME> is the name of the keyvault
<NAME> is the name of the secret.
<VERSION> (optional) is the version of the secret (default: the latest version)
This will generate a reference block in the parameters file:
"reference": {
"keyVault": {
"id": "/subscriptions/<SUB_ID>/resourceGroups/<RG_NAME>/providers/Microsoft.KeyVault/vaults/<KV_NAME>"
},
"secretName": "<NAME>"
"secretVersion": "<VERSION>"
}
