@pdhamdhere I split the commits for the bug fix and the documentation update. We do need both to cut a release.

This commit looks good!

Makes sense.

pdhamdhere

Overall looks good. I think we need to re-order tenant admin CLI commands.

+October release is [out and updated to 0.8.1](https://github.com/vmware/docker-volume-vsphere/releases)
 This is a big release, it includes multi tenancy additions and the backend VMDK_OPS service is now multi-threaded.


I would avoid adjectives like "big"! Perhaps highlight 2-3 most significant feature under "What's new?"?

I would also qualify "Multi-tenancy" as tech-preview.

+# Tenancy
+
+Multi-tenancy is implemented via assigning VMs and Datastore to a tenant. A tenant can be granted access to create, delete or mount volumes on a specific datastore. VMs assigned to a tenant can then execute Docker volume APIs on an assigned datastores. Within a datastore multiple tenants can store their Docker volumes. A tenant cannot access volumes created by a different tenant, i.e. tenants have their own independent namespace even if tenants share datastores. VMs cannot be shared between tenants.


How about restructuring little bit;

Tenants can be used to provide isolation between independent groups in shared environment, where multiple groups are using a common infrastructure (compute, storage, network) fabric. Tenants are useful for isolating resources from one tenant from those of other tenants. For e.g. volumes created by TenantA will neither be visible nor accessible to TenantB, even if those volumes reside on storage shared by multiple tenants. In addition, vSphere Administrator can enforce access control policies and set storage quotas for each tenant.
Some attributes that define Tenant;

vSphere Administrator can define group of one or more Docker Host (VM) as Tenant.

Docker Host (VM) can be member of one and only one Tenant.

Docker Host (VM) if not assigned to any Tenant are member of _Default tenant.

vSphere Administrator can grant Tenant privileges & set resource consumption limits at granularity of datastore.

Ok will think about it. I do not want to explain tenancy itself but just how we implement it.

What is relevance of this link here?

We are introducing terms such as datastore without giving any background.. the design spec is public and a good read, we can skip that.

The logic to handle _Default tenant is not implemented yet.

What do you mean "tenancy:ant privileges"? I don't understand. Any typo?

Made some changes to the write up.

@kerneltime datastore is vSphere basics and to use this feature you already need to be familiar with vSphere. I suggest to remove link to vSphere Storage. It seems out of place.

I think it would be better to move the AdminCLI to add/remove virtual machine before those commands to manipulate datastore access privileges.

remove this line. It is a "print" which I forget to remove in the code. Please remove this print at Line 1008 (in function "tenant_access_add")

If it is part of this release we should keep it, once we update the CLI the documentation will need updating as well.

Is it possible for you to include the small fix in this PR too? Just remove remove this print at Line 1008 (in function "tenant_access_add")? This should not affect any existing functionality. Just remove a unused print command which I added for debugging.

Rather than documenting commands in sorted order, I would recommend to document workflow order.

		# Tenancy

		Multi-tenancy is implemented via assigning VMs and Datastore to a tenant. A tenant can be granted access to create, delete or mount volumes on a specific datastore. VMs assigned to a tenant can then execute Docker volume APIs on an assigned datastores. Within a datastore multiple tenants can store their Docker volumes. A tenant cannot access volumes created by a different tenant, i.e. tenants have their own independent namespace even if tenants share datastores. VMs cannot be shared between tenants.
