Extend kubectl get multiclusterservice output

[Josca]

Please extend the command output to improve user experience:

kubectl get multiclusterservice

Current

NAME                AGE
mcs-nginx-ingress   2d12h

Suggested

NAME               STATUS       SERVICES     CLUSTERS   AGE
mcs-nginx-ingress  Creating     3/5          0/2        2d12h

• Column STATUS - Running / Pending / Failed / Succeeded / Unknown
• Column SERVICES - Deployed/Required services count.
• Column CLUSTERS - Updated/NotUpdated clusters count.

@Josca what output you expect in case some services failed on some clusters?

[Josca]

I would follow container-pods logic here if possible - Running, Pending, Failed, Succeeded, Unknown.

I would follow container-pods logic here if possible - Running, Pending, Failed, Succeeded, Unknown.

following this analogy we should consider MultiClusterService as a Deployment, for instance. Deployments does not show statuses of the containers, only Pods.

Say, there is cluster-1, cluster-2 and cluster-3 with service-A, service-B and service-C.
cluster-1 has service-A and service-C failed
cluster-2 has service-B failed.
cluster-3 runs all services successfully.

So, what would be the output?

NAME             SERVICES     CLUSTERS   AGE
mcs-ABC          0/3          1/3        2d12h

• Ok, the comparison with "deployment" is good. So I can imagine this.
• Services 0/3, no service (from 3 defined) runs successfully across all clusters.
• Clusters 1/3, on cluster (from 3 selected) is successfully configured (runs all services).

It doesn't give all info but some useful info:

• 1. There are 3 services defined in mcs-ABC.
• 2. There are 3 clusters selected in mcs-ABC.
• 3. There is some problem with each of 3 services.
• 4. There is one cluster successfully configured.

Does it make sense?
