Nutanix : Get Software Version for each Clusters

Image
Background When doing upgrade campaign, you need to go to each cluster to verify who's got what software version and then check the progress. Sometimes, it could be painful to collect that information, especially when you have a lot of clusters. I was wondering how this could automated, some obvious details can easy be obtained with "classic" API calls, but not everything. Challenge accepted!

Nutanix : SATADOM is dead!

Image
Background I'm one of the many lucky early adopters of Nutanix and my first cluster is older than 7 years old now. Still in good condition and serving test VMs for years. This one was the proof of concept that leads the way to many other clusters. In good condition yes, until mid Jan when I discovered that I've lost one node out of 3 in that cluster!

Nutanix : Free Certifications Voucher !

Image
Background Always wanted to give a try to a Nutanix examen but you cannot afford it ? (between $99 and $199). Your company does not want to pay for it ? There are discounts from time to time, but you need to prepare for the exam, they are not super easy (especially NCP/NCM...). Ok, I have a good news for you !

3D Printing : Remotely Switch on/off your 3D Printer

Image
Background I think, like most of the 3D Printer guys, you have your printer in your basement. This is indeed a great place, but it means each time you are about to start a print, you have to go downstairs, start the power switch, and go back at your computer place and star the print. OctoPrint is easy to get remote access to the printer, but, what about controlling the power switch ?!?

Changes on the Blog

Image
Something New on the Blog Dear Readers, you probably noticed, there are two major changes on the blog starting today : 1) I have added a patreon button on the left  2) There is less ads on the blog. [EDIT 26th March 2022] : I had to roll back the change on the ads, I've lost 98% of my revenue. I will re-evaluate this in a couple of month. Why ? Simply because too much adds kill reader experience and readers are tempted to use ads-blockers . Ads is my only source of revenue for this blog and this revenue is very welcome for the time, the hosting, the domain name, the various acquisitions for tech tests, ... I realized that Ads are actually a very nice source of revenue, but again, too much is too much. As other bloggers, I've registered to Patreon, this is a tipping platform that allows any reader to donate any amount they think I deserve (and they can afford) to support my work. So, feel free to use the button on the left, send any amount you want. In consideration to this opti

Rubrik : Detect & Protect Unprotected VMs

Image
Background We came to a point where unprotected VMs can be out of sight and we could potentially miss protection on some important object. We do not want to apply a default protection at the top level of our infrastructure to avoid any uncomfortable storage usage. So what ? It would be nice to have a script running on a cluster and check what are the unprotected VM and apply an SLA ... mmmh let me think...

Rubrik : Automate Nutanix Cluster Configuration

Image
Background I would like to automate the Nutanix AHV cluster addition on my Rubrik appliances. Either for testing purpose or for more general deployments. In order to achieve this, you need to perform couple of actions and clicks in the UI. But since the Rubrik UI is API-First, of course, that should be doable via API call ? Isn't it ? But why limiting this to only adding new Cluster ? Let's see...

RClone : Mount Google Drive on any File System

Image
Background Would it be nice to directly manipulate Google Drive as part of the OS File System ? Would it be nice to automate backups directly in the cloud ? Would it be nice to stop buying expensive external storage ? The idea is not to send a "all to cloud" message. But sometimes, this very handy to have quickly have access to some centralized storage. Well, I think so. But How ? Cloud Storage is object storage (S3 like), so each files are actually identified by a unique URL and a set of credentials granting or not certain rights. There is a way of course !

Rubrik : Using GraphQL

Image
Background Sending REST API calls to the cluster is sometimes slow and not very efficient. I came across some interesting posts on that topic. It looks like while REST is getting all the results (even the one you are not interested with) it exist another query type that only returns what you are looking for. This is GraphQL. Let's have a look !

Raspbian : I've lost my password !

Image
Background Yeah, I know, I should have written it down in a safe place, in a vault or so. But it happened. I've lost access to my Raspberry taking care of my hotspot and sending my various API calls to my Yamaha Amplifier . This is an issue since I need to adjust some settings !
