Validation for Environment

[nurali-techie]

For namespaceName,

• Create env gets namespaceName in payload, we need to validate if that namespace belongs to chosen cluster using oso.isExists(clusterApiURL, namesapceName)
• Create env namespaceName is blank, how to auto-generate namespaceName
• Reuse existing namespaceName only for deploy (test, stage, prod, custom etc.) but definitely not for build, dev

For clusterApiURL,

• Create env gets clusterApiURL, we need to check with cluster_service.isValid(usertoken, clusterApiURL)

In the first version we will probably auto-generate namespaces. It will simplify managing namespaces in tenant service. Not sure when we would want to generate them. We could do it during env creation if lazy provisioning is tricky.

@alexeykazakov For namespaceName, so it seems that we want to postpone this for now.

@alexeykazakov @dipak-pawar For clusterApiURL, when we creating new_env we also get clusterURL in create_payload. We should check that the clusterURL in create_payload is valid cluster_url and the user who is creating new_env has access (or linked) the given cluster_url. Do we have have any API in cluster_service to check the same ??

@nurali-techie, We have GET /user/clusters -H "Authorization: Bearer $USER_TOKEN" which will give all clusters available to user . you can find more details at http://swagger.goa.design/?url=github.com%2Ffabric8-services%2Ffabric8-cluster%2Fdesign#!/user/user_clusters

That should be easy to do by asking tenant service - there is already such an endpoint: http://swagger.goa.design/?url=github.com%2Ffabric8-services%2Ffabric8-tenant%2Fdesign#!/tenants/tenants_search

Create env namespaceName is blank, how to auto-generate namespaceName

This has to be done in tenant service - to avoid conflicts. There is already a logic that generates the names - it uses information from tenant DB. The tricky thing is that newly the namespaceName can change, for more information see this issue and PR
