Multiple external labels for ruler in jsonnet

[jobinjosem1]

I am trying to build manifests using the JSONnet file below. I have added two labels to the ruler, "cluster_name" and "rule_replica", but in the compiled manifests, only one label is being added. Can someone help me add an additional label to thanos-rule?

local t = import 'kube-thanos/thanos.libsonnet';

// For an example with every option and component, please check all.jsonnet

local commonConfig = {
local cfg = self,
logFormat: 'json',
namespace: 'monitoring',
version: 'v0.29.0',
image: 'myregistry.azurecr.io/thanos/thanos:' + cfg.version + '@sha256:abcd',
replicaLabels: ['prometheus_replica', 'rule_replica'],
objectStorageConfig: {
name: 'thanos-objectstorage',
key: 'thanos.yaml',
},
};

local ru = t.rule(commonConfig {
replicas: 1,
rulesConfig: [{ name: 'thanos-rule', key: 'thanos-rule.yaml' }],
replicaLabels: ['cluster_name', 'rule_replica'],
serviceMonitor: true,
volumeClaimTemplate: {
spec: {
accessModes: ['ReadWriteOnce'],
resources: {
requests: {
storage: '100Gi'
}
},
storageClassName: 'managed-csi-premium-zrs'
}
},
reloaderImage: 'myregistry.azurecr.io/configmapreloader/configmap-reload:v0.12.0'
});

local q = t.query(commonConfig {
replicas: 1,
replicaLabels: ['prometheus_replica', 'rule_replica'],
serviceMonitor: true,
queryTimeout: '60s'
});

local finalRu = t.rule(ru.config {
queriers: ['dnssrv+_http._tcp.%s.%s.svc.cluster.local' % [q.service.metadata.name, q.service.metadata.namespace]],
});

{ ['thanos-ruler-' + name]: finalRu[name] for name in std.objectFields(finalRu) }

replicaLabels isn't a valid arg for the ruler, the label you see is being added here: https://github.com/thanos-io/kube-thanos/blob/main/jsonnet/kube-thanos/kube-thanos-rule.libsonnet#L139

You want to add an additional --label arg to the ruler, and that is not currently supported.
