TLS Handshake failure on Check Login step

Or, “How does the ‘Check Login’ step actually work?”I consistently get a TLS error on any attempt to connect to the new VM from CALM. Every time. This is a blocker for me, as I can’t do much to the VMs during provisioning without this connectivity, and I can’t/shouldn’t do everything in the cloud-init step.  I am able to ssh into the new VMs successfully using the same credentials, so I know that the credential is correct, but I don’t think the credential is the issue - the error is happening before the system tries to use it. The screenshots below are from two different blueprint deployments.Script execution has failed with error: tls: first record does not look like a tls handshake.Could not connect to the service running at 1.2.3.4.From a higher level, how does CALM initiate the connection to the new VM when starting the “check login” step? The TLS handshake issue implies a mismatch of HTTP/S protocols, and/or mismatched TLS 1.1/1.2/etc versions. But this is supposed to be an SSH co

How can I Protect/Prevent a VM from deletion in CALM/Self Service?

I am looking for a way to protect the VMs that I’ve stood in as Applications in Calm/Self Service from accidental deletion (mostly by me). I don’t see a way to do this in any areas of Prism or Calm, and I don’t see anything in the Policy Manager docs that would address it, either. Is there any kind of pattern or feature for this? Thanks

Round-tripping a VM definition using PowerShell 5.1 in Calm results in HTTP error 400

Hi all!This might not be a Nutanix Calm specific problem, but since I’m experiencing the problem within Calm I’m posting a question here (as well). :)I'm grabbing a VM definition using GET https://${PCHostAddress}:9440/api/nutanix/v3/vms/$VMUUID. I convert the payload to an object using ConvertFrom-Json, manipulate it using .Remove() to remove the Status section (among other things), and convert it back to JSON with ConvertTo-Json.When I send the modified payload back using PUT https://${PCHostAddress}:9440/api/nutanix/v3/vms/$VMUUID, I get a "(400) Bad Request." Thinking I screwed something up when modifying the payload, I removed the part of the code that changes the object but still got the same error, even though I'm "just" converting the unmodified payload from and to JSON.Sending back the payload without converting from and to JSON results in a "(422) UNPROCESSABLE ENTITY”, as it should.In this case the -Depth parameter isn't the culprit as far as I can tell (I've added -Depth 10

How does Calm execute PowerShell on an endpoint?

Hi all!In an attempt to solve a problem with “round-tripping” JSON I’ve concluded that the only fix is to use PowerShell 7 since the ConvertTo-Json cmdlet in version 7 allows me to escape the troublesome characters.This solution might just be me robbing Peter to pay Paul though as I now face the issue of getting Calm to use PowerShell 7 instead of the default 5.1 (a.k.a. Windows PowerShell).I’ve gone so far to set the default PowerShell remote endpoint (windows.powershell) to point to PSH 7, which works if I do a traditional Enter-PSSession but not if I execute a PowerShell script in a Calm runbook.Which leads up to the title of this topic, how does Calm execute PowerShell on an endpoint?Since it’s using port 5985 it should be WinRM/WSMAN/remote PowerShell, but it completely ignores the fact that the default PSH remote endpoint is pointing to PSH 7.Is it using another endpoint? Or is it not using WinRM after all?

How to use Variable Types from the library?

I would like to create variables that are reusable in blueprints - things like package store URI, proxy URL, etc. I don’t think it makes sense to define these in every blueprint, as they’re identical; we want to keep that kind of thing DRY.The docs state that Variable Types defined in the Library are reusable across blueprints. But if I define MY_VAR as a new Variable Type with a value, it has no value when expanded in a blueprint script as @@{MY_VAR}@@. What is the trick to defining these vars at the Library level and using them in Blueprints? Thanks!

Windows Authentication Setup with CALM

Hello, I'm curious if anyone else has had issue getting Windows authentication with WS-man setup within CALM for the Login Check and remote execution of scripts. I have followed the docs and redone the setup a few times for validation, but the login check still fails with a vague error that just says to check out WINRM troubleshooting help. What's odd is that after I provision the Windows image, I can manually invoke commands for remote execution and login with the following command against the newly provisioned IP: PS C:\Users\Administrator> Invoke-Command -ComputerName 10.32.4.246 -ScriptBlock { $PSVersionTable.PSversion } -Credential administrator@domain.com My Karan service is installed and configured with a domain administrator, all PS commands in the document have been run as "administrator" on the Karan server and the target base Windows image as required.

Passing a variable through to cloud-init script in Calm?

I know in Calm you can create variables in the service, and then use those variables throughout the config using @@{service.variable}@@. However, it doesn't seem like you can use those in cloud-init scripts. I'd like to be able to pass a variable that the user sets at the time of deployment (the IP address), which would then be used in the cloud-init script. I've tried something like this, to no avail: [code]#cloud-config hostname: HAProxy1 fqdn: HAProxy1.domain.com ssh_pwauth: yes write_files: - path: /etc/sysconfig/network-scripts/ifcfg-eth0 content: | DEVICE=eth0 BOOTPROTO="none" IPADDR="@@{HAProxy1.IP_Address}@@" PREFIX="24" GATEWAY="172.25.51.254" DOMAIN="VIPCUSTOMERS.COM VTINFO.COM" DEFROUTE="yes" ONBOOT="yes" DNS1="172.25.51.10" DNS2="172.25.51.2" IPV4_FAILURE_FATAL="yes" IPV6INIT="no" runcmd: - [ifdown, eth0] - [ifup, eth0] [/code] Where HAProxy1.IP_Address is a u

Basic Patterns for creating base images from vms

I have been relatively successful using a blueprint to define all the tasks and installations to create a solid VM. I now want to bake this VM into an image, so it has all those tasks already performed on it. I tried creating a VM template, but when i launch an instance from it, it has no Dynamic IP assigned. What is, or can someone point me to, the best practice/standard pattern for building a catalog of images with various apps and tasks pre-baked-in, so we don’t have to apply their installation every time?thanks!

Error "'NoneType' object has no attribute 'get'" when executing runbook via API

Hi.I’ve verified with this post and this post that I’m sending the parameters correctly and that the variables in my runbook are set to Runtime. I’m also doing a POST call but I still get an internal server error with the message "'NoneType' object has no attribute 'get'".Here’s the body of my call:{    "spec": {          "args": [            {              "name": "email",              "value": "mema@tlke.se"            },            {              "name": "displayName",              "value": "Mom MEmem"            },            {              "name": "userName",              "value": "momemom"            },            {              "name": "accountName",              "value": "MAM, MSM 1"            },            {                "name": "ticketID",                "value": "794"            }          ]        }      }    }  }The runbook has multiple tasks, does that change how I send arguments to it?Thanks.

Does Apps management (Calm) support ESXi in PrismCentral 5.8?

I deployed a Nutanix Cluster (AOS version 5.8) with ESXi 6.5. And I deployed a Prism Central 5.8 on it. There're some articles on internet, saying App Management supports ESXi, starting from PrismCentral version 5.7. Is it true? In my case, I can't find [b]Self Service & Apps[/b] from the pull-down list, when I click question mark icon in the main menu on PrismCentral 5.8. I did see "PC Scale out", "Enable app management" and "Microsegmentation", but not "[b]Self Service & Apps".[/b] When I click "Enable app management", I see the following error. [list] [*]Precheck failures: [/list] Host Cluster Registered Please check that the cluster on which this Prism Central is hosted is registered to it. I had already registered my Nutanix cluster into this PrismCentral. It looks to me that App management or self service doesn't support ESXi, correct? Or is there anything I missed?

Why, exactly, does Calm have to be on a Nutanix cluster?

Hi.I’m the first to admit that I read the documentation for Calm a bit too quickly and didn’t really reflect on the meaning of “The Prism Central in which Nutanix Calm is running is registered with the same cluster.” and “Nutanix Calm is supported only on AHV and ESXi hypervisors on a Nutanix cluster.”After trying and failing to run this on an existing VMware cluster, that the Prism Central/Calm installation doesn’t own, I re-read the documentation and realized that I’d glossed over the actual requirements.I mention this to clarify that this isn’t a post about unclear documentation or incorrect requirements. I goofed, as simple as that. :)What I do want to know though is why these requirements exist. I have talked to my contacts at Nutanix and I so far I haven’t got a proper answer to this question.Can anyone please explain, in detail, why I can’t run Calm on an arbitrary VM?

How does the while loop in Calm actually work?

Hi!I need help wrapping my head around how the while loop in Calm works. The documentation is unfortunately not helpful at all. :/The first thing I can’t understand is why a while loop has a fixed number of iterations. This to me is a for loop. A while loop runs while a condition isn’t met.The second thing that’s confusing is the exit condition that I can set to Success, Failure, or Don’t Care. I guess that Don’t Care turns the while loop into an actual for loop?The Success or Failure condition is as far as I can tell completely out of my hands as this is based on the result of the execution of the task(s) within the loop and not a parameter I control. Do I have to fail a task on purpose to keep the loop going if I choose Success as my exit condition?What happens if I have multiple tasks in the loop, do all tasks need to fail or succeed for the exit condition to trigger?Is it possible at all to set a parameter in one of my scripts and then use that as an exit condition?Thanks.
