I have a k8s cluster, and I saved another k8s cluster’s kubeconfig in the first k8s cluster as secret. I want to build a k8s provider from the kubeconfig secret.
Copy code
export const secret = k8s.core.v1.Secret.get("kubeconfig", "admin/kubeconfig-for-admin");
export const k8sProvider = new k8s.Provider("new-cluster", {
    kubeconfig: secret.stringData["kubeconfig"],
});
But the
k8sProvider
does not work as expected, I couldn’t see the kubeconfig field in it. Does anyone know why it is that? I’m pretty sure the kubeconfig was stored as base64 string in the
admin/kubeconfig-for-admin
.

we do it without any problem, but from an azure keyvault
perhaps its to do with base64 encoding, can you access the binaryData field or something maybe
we pretty much do :
Copy code
const kubeConfig = azure.keyvault.getSecret({
            keyVaultId: keyvaultId,
            name: args.KubeConfigSecretName
        });
return new kubernetes.Provider(name, { kubeconfig: kubeConfig.value })
fwiw, when we create the secret it's from kubeConfigRaw property of the cluster

Thanks, do you know how to retrieve the secret data from k8s secret? The
secret.data
is
pulumi.Output<object>
, I don’t know how to extract the specific value from it.

use .apply()
so like secret.data.apply(s => new kubernetes.Provider(.. { kubeconfig: s })) or something like that

After some Googling I finally make it work:
Copy code
const secret = k8s.core.v1.Secret.get("kubeconfig", "admin/kubeconfig-for-admin");
type secretData = { [key: string]: string };
export const kubeconfig = secret.data.apply(v => Buffer.from((v as secretData)["kubeconfig"], "base64").toString("ascii"));
const provider = new k8s.Provider("cluster", {
    kubeconfig: kubeconfig,
});
Thanks for your help @better-rainbow-14549.
