Provide human understandable target group names

[sdavids13]

I would like to use CloudWatch to gather metrics dealing with various Target Groups behind an ELB but is very difficult to at-a-glance understand which Target Group is having issues due to the UUIDs/hashes being generated as the names currently. It would be nice to have some sort of configurable option to specify the name or at least a prefix to denote what Kubernetes service you are using (default value to a combination of servicer name + namespace would be nice).

one option is by using the --alb-name-prefix, we get the option to prefix the alb and the target group with a useful name. the alb and target group then gets created with <prefix-name>-......

I have been planing to change the targetGroup name to k8s-{namespace:8}-{name:8}-{uuid:10}.
uuid is hash consisted of clusterName, targetType, protocol, etc. Which should be good enough for general use cases.
(actually in my NLB PR kubernetes/kubernetes#74910, i did that name change for NLB targetGroups).

For Ingress controller, the --alb-name-prefix have forbids me to do so, needs to figure out the real use case of such flag.

[sdavids13]

Is the {name} the name of the k8s service configured in the Ingress Controller? If so, that should be sufficient being able to identify what the target group is associated with.

Do we have a solution for this?

[M00nF1sh]

@rverma-nikiai
What's your ideal name for targetGroups?
Will k8s-{namespace:8}-{name:8}-{uuid:10} be good enough for you?

[rverma-nikiai]

@M00nF1sh I would prefer k8-{ing/svc name}-{namespace}-{UUID:10}. Your suggestion is very good too.

[rverma-nikiai]

Also it would be nice that once we deploy the fix it should take care of deleting the existing random names and creating new target groups

@M00nF1sh Looking forward to a release with this feature. Thanks

Custom ALB names are now supported via annotations. Can this be provided for target group names as well? Or at least use the same custom ALB name when creating the target group?

[guillaumecle]

Should we create a dedicated issue for the ability to name the target group as well?
