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

Passing cpu/ram/disk runtime vars via Jenkins calm plugin

I initially developed a Jenkins pipeline to launch Calm blueprints using the raw API, which works, but i hadn’t yet figured out how to pass runtime params to it.It was then that i found the Jenkins plugin, which simplifies the process significantly. It is easy to pass values to the app variables that are exposed in the blueprint. What i don’t see is the ability to pass runtime-editable fields. For example, i can set an App Variable for a user-supplied value, via the plugin. But I don’t see a way to set, for example, the `vCPUs` field that I have marked as a runtime field.It is available to set when launching the Blueprint via the Prism UI, but is it possible to set these fields using the Jenkins Plugin?PS: i am also unclear how to set params via the raw API, but i’ll ask that in a separate topic.

CALM blueprint editor - user-modifiable field setting does't stick

When setting up my blueprints, i want to lock down most of the configuration to prevent user error. I basically only want a user to be able to adjust the cores, RAM, and size of the data disk. So, i’m clicking the running-person icons to set them to black, meaning not-user-changeable. However, when i Save the change, it goes back to blue. I can’t get the user modifiable/not-modifiable config to stick. Am i missing something here? Thanks!

Can I create a lease or timeout on an Application or VM?

Back in my VMware vRA days, we could set VMs to expire and delete themselves after a set period of time, called a Lease. This prevented test VMs lasting too long and using up resources unnecessarily. The default was seven days, and it could be extended or set as desired by the users if a VM was needed for longer. Is there a way to configure a similar mechanism in CALM/Self Service?

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!

How do I launch a blueprint with a project reference?

Hi all!I’m guessing I’m missing something obvious here, but I can’t figure it out so I’m hoping that the community can give me a helping hand. :)I want to launch a blueprint using the /blueprints/{uuid}/launch API call as the “simple launch” call doesn’t do what I want. I want to automatically associate the new application with a project and as far as I can tell I have to use the “normal launch” for that.I grabbed the exact payload that Prism Central/Calm sends and have spent half a day trying to clean it up so that I can re-use it, but this is where I get nowhere. If I remove too much, I get an error directly from the API but most of the time I can submit the request without errors.Compounding the issue is that there is nothing showing in the Tasks-indicator in Prism Central, not even an error or a warning, after I sent in the call - there is simply no trace at all of the task I just created.If I check the pending launch details with the /blueprints/{uuid}/pending_launches/{launched_u

Where can I find the UUID of a single-VM blueprint app profile?

Hi all.I have a single-VM blueprint that I want to launch using the “Launch blueprint” API call. The schema for this call requires that I specify an app profile UUID but no matter where I look, I can’t find any reference to this UUID, neither in the UI nor via API calls.To be fair, I haven’t gone through every single API call so there might still be one that eludes me.How do I know what app profile UUID to include in my payload when using the “Launch blueprint” API call?Thanks!

app_blueprint_template error when deleting images

This question has been asked a few times on this forum but has never been fully answered.When i try to delete a disk image, I get an error:Attribute _app_blueprint_template not set I can not find any mention of this attribute anywhere, and I can’t find any other way to delete the image. I tried the API method from this post but it has the same result.What’s the trick here?

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!

Disks in Catalog Items not showing in Blueprints

I want to build a blueprint that provisions a CentOS8 VM. I have added a CentOS8 disk to the Catalog Items list in Prism Central. When I go to build/edit my blueprints in Calm/Self Service, the disk does not show up as an option in the Disks configuration field. How do i enable a disk image from the Catalog Items to be available in Calm blueprints?Thanks!

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

Nutanix Calm API request returns incorrect task UUID

I am currently using Nutanix Calm API v3. After creating a crash-consistent VM recovery point using the POST endpoint /api/nutanix/v3/mh_vms/{vm_uuid}/snapshot and verifying that it exists on Prism Central, I attempted to revert the VM to this recovery point using the POST endpoint /api/nutanix/v3/mh_vms/{vm_uuid}/revert using the recovery point uuid in req body. The response has 200 status code but the task reference returned has task_uuid value of ‘something’. I also cannot see any alerts on PC indicating that the VM revert task has been attempted. May I know if anyone has experienced this issue before and how I might rectify this issue? Im not sure how to proceed since the API request appears to be successful. In particular, I would like to understand the circumstances under which Calm API returns tasks with uuid value of ‘something’. Thanks!

Cannot revert VM from recovery point on Prism Central

I have attempted to create a VM recovery point on Prism Central and revert it from the recovery point. However, I am getting an info-level message that the recovery point is degraded and that the recovery Point for VM failed to capture associated policies and categories because the network name is not available for the VM.The VM revert task also does not seem to have been executed as there is no event confirming success. The VM is created from a blueprint that is part of a project with a configured VPC, and I have already verified that there are no issues in connection between PC and PE. May I know possible reasons for why this is happinening and how I might resolve this? I have consulted the link https://portal.nutanix.com/page/documents/kbs/details?targetId=kA00e000000CyDeCAK but it seems to be targeted at VMs running on ESXi, our VMs run on AOS/AHV. Thanks!
