A really really probably simple thing here.. Is there any way of making

k8s.yaml.ConfigFile/ConfigGroup

apply the resources to a namespace? I don't want to muck with the files, and they don't have a namespace declared in the yaml, so the transformation I've got seems to fail.. For instance:

const keyCloakAccounts = new k8s.yaml.ConfigGroup("keycloak-roles-accounts-bindings", {
                files: [
                    `${pathToKeyCloakOper}/role.yaml`, 
                    `${pathToKeyCloakOper}/role_binding.yaml`,
                    `${pathToKeyCloakOper}/service_account.yaml`
                ],
                transformations: [
                    (obj: any, opts: pulumi.CustomResourceOptions) => {
                        obj.meta.namespace = keyCloakNamespace.metadata.name;
                    }
                ]
            },{
                provider: args.providers.kubernetes,
                parent: this,
                dependsOn: keyCloakNamespace
            })

Which fails with:

TypeError: Cannot set property 'namespace' of undefined

Easiest way is to set the namespace on the Provider. https://www.pulumi.com/docs/reference/pkg/kubernetes/provider/#namespace_nodejs
