Last part doesn't work, because ConfigFileOpts.file expects a string. I've tried:

rancherCluster.clusterRegistrationToken.manifestUrl.apply((manifestUrl) => {
    new k8s.yaml.ConfigFile(name + "-import", {
        file: manifestUrl
    }, {
        provider: cluster.provider,
        dependsOn: [cluster, rancherCluster]
    });
});

Yeah, this is unfortunate about the current

ConfigFile

implementation. I’m working on the .NET SDK now and I made it

Input<string>

rather than string. I believe the same needs to happen in node.

Do you know if I can help in anyway? May I contact someone to raise the issue and offer my help?

You can definitely raise an issue at https://github.com/pulumi/pulumi-kubernetes

Many thanks Mikhail

If “create in apply” doesn’t work, the only workaround I know is to hard-code it somehow
