Subscribe to vGhetto Nested ESXi Template Content Library in vSphere 6.0

04.08.2015 by William Lam // 23 Comments

During the early development of vSphere 6.0, one of the features that I got an early sneak preview of was the Content Library which originated from vCloud Director's Content Catalog capability and has now been pushed down into the core vSphere platform as part of VCD's "Convergence" plan.

Although there are some initial limitations with this first release of Content Library such as not being able to mount an ISO directly from the Content Library as example, which I do agree it should have just worked and not requiring a manual datastore browse for this operation to work. I know the Engineering team is aware of this as it was something our team had also provided feedback among other things, so hopefully this will be fixed very shortly.

Having said that, I do see a huge potential with the Content Library and all the interesting use cases it can enable not only for vSphere but also for other products such as vRealize Automation as well as vCloud Air. One area that caught my attention when I first heard about Content Library is the the fact that the publishing and subscription capability works over simple HTTP(s). I immediately had a light-bulb moment and thought would it not be cool if you could have a custom Content Library that would be hosted on some external cloud storage such as Amazon S3 as en example and be able to publish that so others could subscribe to it in their vSphere environment?

Fortunately, because Content Library works over standard HTTP(s) and with the help of one of the Content Library Engineers I was able to create my very own vGhetto Nested ESXi Template Content Library for both vSphere 6.0 and vCloud Directory based environments which is currently being hosted on Amazon S3.

vSphere: https://s3-us-west-1.amazonaws.com/vghetto-content-library/lib.json
vCD: https://s3-us-west-1.amazonaws.com/vghetto-content-library-vcd/lib.json

The library contains all of my Nested ESXi / VSAN OVF Templates that I have created over the years and by publishing them in in my public Content Library, anyone can now easily subscribe and pull down the latest OVF templates to deploy directly in their vSphere/vCD environment. You no longer have to manually download the OVFs and as I add new content, the Content Library will automatically synchronize the changes to your local environment.

The vGhetto Nested ESXi Template Content Library currently contains the following 7 OVF's which total to 1.43MB:

Nested-ESXi-3-Node-VSAN-6.0-All-Flash-Template
Nested-ESXi-3-Node-VSAN-6.0-Template
Nested-ESXi-3-Node-VSAN-Template
Nested-ESXi-32-Node-VSAN-Template (not available when subscribing from VCD)
Nested-ESXi-6-Node-VSAN-6.0-FD-Template
Nested-ESXi-64-Node-VSAN-6.0-Template (not available when subscribing from VCD)
Nested-ESXi-VM-Template

Here are the instructions for subscribing to my vGhetto Content Library using the vSphere 6.0 Web Client:

Step 1 - In the main Home page, click on the Content Library icon

Step 2 - Create a new Content Library which will be used to subscribe to my vGhetto Content Library.

Step 3 - Select "Subscribed content library" and enter the following URL: https://s3-us-west-1.amazonaws.com/vghetto-content-library/lib.json and make sure to select "Download all library content immediately". There is currently a limitation in the way the metadata is read from OVFs that prevents the on-demand setting to be used when subscribing to 3rd party Content Libraries.

Step 4 - Select the storage which will be backing your Content Library. This can be either a local filesystem path on your vCenter Server or by using a vSphere Datastore.

Step 5 - If the new Content Library had been successfully created, the content will start to synchronize to your local system and once the OVF/VM icon appears, then you know the Nested ESXi / VSAN OVFs templates are ready to be deployed in your environment as seen in the screenshot below.

Note: You will notice that even though we are pulling down all seven OVF templates, they are only consume a measly 1.43MB as these are empty VMs shells and I am also using the OVF Dynamic Disks feature which allows you to specify the size of the VMDK upon deployment.

UPDATE (4/24) - It turns out that 3rd Party Content Libraries can also be subscribed from within vCloud Director but because it does not support Dynamic Disks, the synchronized will fail. I have created a separate library specifically optimized for vCD which you can find the URL at the top and you can then subscribe to my vGhetto Content Library as seen in the screenshot below. You will notice that the 32 and 64 Node VSAN Template is not available and the reason for this is that apparently there is a limitation in the number of elements it can parse.

This is a pretty powerful feature in my opinion and I can already see custom content libraries not only from VMware but also from our partner eco-systems providing their latest solutions (Virtual Appliances) as well as other file content as Content Library can store pretty much anything. In a future blog post, I will go through the details on how you can create your own custom Content Library, so stay tune. In the mean time, if you are using vSphere 6.0 and and would like to be able to quickly pull down the latest Nested ESXi / VSAN OVF templates, be sure to subscribe to my vGhetto Content Library!

vCenter Server 6.0 Tidbits Part 3: Finding all deployed Platform Services Controller

04.08.2015 by William Lam // 9 Comments

In vSphere 6.0, there are a list of recommended topologies which can viewed in VMware KB 2108548. In the event that you need to locate all available Platform Services Controllers in your environment, you have a couple of options depending on type of access you have and the state of your environment (e.g. vSphere Web Client is down). Before taking a look at the solutions, here is a diagram of my vSphere 6.0 lab environment and its configuration: 2 PSCs configured for replication with 2 VCs joined to PSC1 and another VC joined to PSC2.

Option 1:

The first option to find this information is using the new System Configuration UI which is available in the vSphere 6.0 Web Client. You can quickly view all Nodes and their type as seen in the screenshot below. This would be the quickest and most efficient method if access to the vSphere Web Client is available.

Option 2:

We can also connect to a new service in vSphere 6.0 known as the Component Manager via its MOB (Managed Object Browser) interface. You will need to open a browser and connect to the following URL and substituting it with the Hostname/IP Address of one of your PSC:

https://psc-01.primp-industries.com/cm/mob/?moid=ServiceManager&method=Search

If you do not know the Hostname/IP Address of your PSC Server, you can always find it by going to the vCenter Server Advanced Settings and searching for pattern "sso.admin" and you will see the address of your PSC Server as seen in the screenshot below.

Once you have authenticated in, you will need to add the following snippet into the text box:

<searchCriteria>
<serviceType>
<productId>com.vmware.cis</productId>
<typeId>sso:admin</typeId>
</serviceType>
</searchCriteria>

Note: For programmatic access, please refer to Option 3 for more details.

Next, click on Invoke Method to execute the query and if everything was successful, you should see entries under "serviceEndpoints" for all your PSCs as seen in the screenshot below.

Option 3:

The final option is to of course retrieve this information programmatically using the new vCloud Suite SDK which is part of the vSphere 6.0 release. There are 6 new SDKs: .Net, Java, Perl, REST, Python & Ruby and you can find more information here. In this example, I will be using the vCloud Suite SDK for Python and using the sample located under the "lookupservice" directory called print_services.py You will need to download and extract the contents of the SDK onto a system that has a Python interpreter installed and below are the instructions for running this particular sample script.

First, you will need to edit a configuration file and provide some details to one of your PSC's

VMware-vCloud-Suite-SDK-Python-6.0.0/client/samples/src/sample.cfg

Here is an example of what the file should look like for my environment:

[connection]
lswsdlurl=file:///root/VMware-vCloud-Suite-SDK-Python-6.0.0/client/wsdl/lookupservice.wsdl
lssoapurl=https://psc-01.primp-industries.com/lookupservice/sdk
ssousername=*protected email*
ssopassword=VMware1!

Next, change into the following directory:

cd VMware-vCloud-Suite-SDK-Python-6.0.0/client/bin/

Finally, to run the sample script you will need to ensure run_sample.sh (wrapper script) is set to executable and then run the following:

./run_sample.sh ../samples/src/com/vmware/vcloud/suite/sample/lookupservice/print_services.py

If everything was configured successfully, you should see similar output as shown in the screenshot below:

vCenter Server 6.0 Tidbits Part 2: What is my SSO Domain Name & Site Name?

04.07.2015 by William Lam // 27 Comments

When deploying an Embedded vCenter Server or an external Platform Services Controller, one of the configurations you will be asked for is the vCenter Single Sign-On Domain Name and Site Name as seen in the screenshot below.

In addition to troubleshooting, you will also need to know about the SSO Domain Name + Site Name if you plan on deploying additional Platform Services Controller for replication purposes or additional vCenter Servers. It is important to note that you do not need to know this information explicitly when deploying using the new Guided UI Installation. You just need to know the hostname/IP Address of your PSC as the rest of the information will automatically be obtained by the tool.

The issue only arises when you are trying to perform a Scripted Installation and this is where you will need to provide both the SSO Domain Name and Site Name and below are the instructions on retrieving this information.

First off, you will need to login to your Platform Services Controller whether that be on a Windows Server or the VCSA.

SSO Domain Name

You will find it in the following two configuration files:

Windows:

C:\ProgramData\VMware\vCenterServer\cfg\install-defaults\vmdir.domain-name

VCSA:

/etc/vmware/install-defaults/vmdir.domain-name

VCSA 6.0u2:

/usr/lib/vmware-vmafd/bin/vmafd-cli get-domain-name --server-name localhost

For more details, check out my previous blog post: vCenter Server 6.0 Tidbits Part 1: What install & deployment parameters did I use?

SSO Site Name

First, you will need to identify where your Lookup Service is running on which is located on your PSC or your Embedded VC instance. What we are ultimately looking for is Lookup Service URL which is in the following format: https://[SERVER]/lookupservice/sdk If for whatever reason you do not know where your PSC is, then you can login to your vCenter Server and find the Lookup Service URL by running the following command:

Windows:

"C:\Program Files\VMware\vCenter Server\vmafdd\vmafd-cli.exe" get-ls-location --server-name localhost

VCSA:

/usr/lib/vmware-vmafd/bin/vmafd-cli get-ls-location --server-name localhost

Once we have the Lookup Service URL, we can then find the SSO Site Name by running the following command:

Windows:

"C:\Program Files\VMware\vCenter Server\python\python.exe" "C:\Program Files\VMware\vCenter Server\VMware Identity Services\lstool\scripts\lstool.py" get-site-id --url https://vcenter60-6.primp-industries.com/lookupservice/sdk"

VCSA:

/usr/lib/vmidentity/tools/scripts/lstool.py get-site-id --url https://vcenter60-6.primp-industries.com/lookupservice/sdk 2> /dev/null

VCSA 6.0u2:

/usr/lib/vmware-vmafd/bin/vmafd-cli get-site-name --server-name localhost

As you can see the process to find the SSO Site Name is not really intuitive, but I know Engineering is aware of this and has plans to simplify this in the future.
