Namespace Management

[mnkg561]

Is this a BUG REPORT or FEATURE REQUEST?: FEATURE REQUEST

What happened: We need to support the following functionality as part of Namespace Management

1. Allow users to configure steps involved in Namespace Creation.
2. Must allow options to choose applicable clusters

What you expected to happen:

1. Users should be able to design namespace creation template based on environment, cluster and cloud.
2. New namespace creation should create the namespace based on the template it is referenced to.

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

Environment:

• manager version
• Kubernetes version :

  $ kubectl version -o yaml

Other debugging information (if applicable):

- controller logs:

$ kubectl logs

Should we keep using the argo workflow? The template should be extensible to add some extra things than just the manifests. What could be the options?

• Name Type DependsOn: CreateOnly OneOf{ ServiceAccount Role RoleBinding ResourceQuota }

clusterName: Name of the cluster in which this namespace needs to be created params: map[string]string - this should be used to provide the runtime values for the exportedParams for the namespace template

templateName: Name of the namespace template to be used for this and namespace template must exists. Optional
