A couple of months back I had tossed out an idea on Twitter asking if others would like to see an automatic update mechanism built into the ESXi Embedded Host Client which would allow users to easily update to newer releases of the Fling versus the current method which requires copying the VIB and then running command in the ESXi Shell.

To no surprise, the feedback was an astounding yes! Literally within a couple of hours, Etienne Le Sueur, one of the two VMware Engineers working on the Fling shared a screenshot that demonstrated that this would possible. The first release of this feature would simply ask for the URL to the updated ESXi Embedded Host Client VIB and this was included in the v3 release of the Fling.
One additional tidbit that Etienne had shared was that the way this feature was implemented, it was not only limited to Embedded Host Client VIB but you could do this for any ESXi VIB. This is done by using the vSphere API and calling into the InstallHostPatchV2_Task() method which allows you to install or update an ESXi VIB from a URL source. Most recently, there a twitter conversation between myself, Etienne and Christian Mohn on how this capability could be further extended to include updating ESXi itself which can either be from an Image Profile or offline bundle. For those with a detailed eye, you may have noticed that the same API method can also support an offline bundle URL which would make this possible. As of right now, the feature is actually included in an internal build of the Embedded Host Client, but perhaps we will see this in a future update of the Embedded Host Client? 😉
Going back to the original topic of this blog post, to use the VIB install/update mechanism, you would need to first upload the ESXi VIB to an HTTP Server and then specify the URL. This is fine if you have an existing HTTP Server but if you do not, it is sort of a pain and though there are other methods like uploading directly to the ESXi's python based HTTP Server as mentioned by Christian, it would still require using something like SCP which is an additional step. My initial goal and hope was to be able to install or update an ESXi VIB or ESXi itself using purely the Embedded Host Client. This would keep things simple and not require things like SSH to be enabled on the ESXi host.
After a bit of brainstorming with Etienne, he actually found a super clever way of accomplishing this after our conversation. The idea I had was to make use of the ESXi Datastore to store the VIB which can be uploaded through the Embedded Host Client. By default, there is also an HTTP based interface to the datastore, however it requires authentication which would be a problem. The neat idea that was suggested was why not try to specify the local VMFS path to the ESXi VIB (e.g./vmfs/volumes/datastore1/my.vib)? It turns out that this actually works as well!
With just two easy steps, you can now upload an ESXi VIB and then install/update all using just the Embedded Host Client with no additional dependencies
Step 1 - Navigate to the Datastore section in the Embedded Host Client and then upload the ESXi VIB that you wish to install or update.
Step 2 - To install/update the VIB, click on Help in the upper right hand corner of the Embedded Host Client and select the "Update" option. Specify the local VMFS path to ESXi VIB and then click on Update to apply.
Note: A reboot may be required after applying a new VIB. It will be your responsibility to shutdown the VMs and reboot the ESXi host for changes to go into effect if required.
At this point, you should also see a task kicked off applying the VIB. If there are any errors thrown, they will be displayed else you should see a successful task completion. For educational purposes, here is a quick screenshot of /var/log/esxupdate.log showing the VIB being applied, this can be used for further troubleshooting if required.
Hope you enjoyed this neat little trick and with just two easy steps you can install or update any ESXi VIB using the Embedded Host Client without additional dependencies or enabling SSH on the ESXi host.
can this be orchestrated at the command line ?

Kindly place the browse button in the "Install update" popup window
We spent an hour trying to get the path right, here is a how to figure this out! You need to use the numerical representation of the word(name) of your datastore. This can be found in the location area after logging in locally to the host(as root) and looking at the data store. Here is an example
