Macro for prism central in self-service

HeyIn Calm (Script that I have in old lab, AOS v6.5) My script (part in blueprint) use REST API and ip is used as localhost: Now, In self-Service not accepted localhost (security reasoning).In Self-Service Administration and Operations Guide I see some script that use @@{pc_ip}@@ but this is not real variable.Is there any alternative to get the Prism Central IP and use it in my script? since I use the same script in many PC, It not good practice to hard coded the IP..alternatively: is there a way to get the cluster list (instead use API)? Thanks

Nutanix network setting problem

Hi sir I have three devices. Model is NX-1175S-G8The networks of the three NXs will be connected to a 10G switch.This 10G switch will be connected to a 1G switch.Each NX is connected to the switch with two network cables.The function is to use NCM. However, after setting up more than 30 VMs, the network will be disconnected seriously. It is found that it will be stuck on the 10G switch. However, if the port connected to NX is limited to 1G, it will work normally.But the device will send out a warning message.CVM not uplinked to 10GbE NICIt was detected that the Nutanix packets were very large, causing the 10G switch to be unable to handle the load.(about 1.61Gbps)Because there is only one line going up to the 1G switchI have tried another brand of 10G switch, but the problem is the same.If the 10G switch and the 1G switch do not use lacpHow can I adjust the Nutanix network?Thanks ​​​​​​   Network traffic

Ansible Automation Platform Integration in Self Service

Hi!I’m looking for an out of the box integration of AAP to import/install in the Self Service, to get inventories, credentials, job templates, … from our AAP, to be able to launch job templates from Self Service (and retrieve the result of jobs :)). This way I can automate some tasks, like post-provisioning tasks after VM deployment or some day2 actions.Regards,Fred

Nutanix Cloud Services vs AWS

Hello Community,Hope you are doing well.I would like to know if these following AWS Services have their equivalents in Nutanix Private Cloud : Amazon Simple Notification Service : allows developers to send messages to many subscribers through communication channels such as email, SMS (text messages), mobile push notifications, and HTTP/HTTPS endpoints. Amazon Simple Queue Service : Amazon Simple Queue Service (Amazon SQS) lets you send, store, and receive messages between software components at any volume, without losing messages or requiring other services to be available. Amazon Data Firehose : provides the easiest way to acquire, transform, and deliver data streams within seconds to data lakes, data warehouses, and analytics services.  AWS Lambda : serverless compute service for running code without having to provision or manage servers AWS API Gateway :  fully managed service that makes it easy for developers to publish, maintain, monitor, secure, and operate APIs at any scale Amaz

Nutanix Calm DSL version requirements

Hi, I am interested in using Nutanix Calm DSL to automate certain Calm tasks, specifically updating our existing applications to use python3 escripts instead of python2. I noticed that the docker tags for DSL only run from v3.7.0. May I know if there is a minimum version of Nutanix Calm that DSL needs to run on? We are using Calm v3.5.2 at the moment and I don’t have an environment with a later version to try out DSL. Thanks.

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!

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!

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
