Support include/select namespaces in controller #620

Closed kernel164 closed 4 years ago

kernel164 commented 4 years ago

Bug Report

I see lot of activities in controller logs. Why is controller trying to access ingress namespace or any other namespaces?

I see ignoreNamespaces option in helm chart. is it possible to have includeNamespaces/selectNamespaces so that I can define which namespaces maesh should pick up?

Output of controller log: (1.2.0)

What is your environment & configuration (arguments, provider, platform, ...)?

EKS k8s 1.16 maesh 1.2.0

In order for Maesh to discover services and SMI resources, it listens for change events in every namespace except the one specified in the ignoreNamespaces option and kube-system.

I would also be in favour of providing a new option in which we could specify exactly which namespace we would like to listen on. Adding this won't be a breaking change and would allow operators to control accurately Maesh scope.

@kevinpollet, @SantoDE WDYT?

Agreed :-)
