 Deploy linux machines in Aria Automation with no domain, only short name

https://knowledge.broadcom.com/external/article?articleNumber=390638

Issue/Introduction

In some cases, it may be necessary to deploy Linux machines from Aria Automation where the machines are configured with static IPs and provisioned using only short names, without the need for a domain name.

 

Environment

Aria Automation 8.x

Cause

Aria Automation's network profiles require a domain name to be specified during the deployment process. There is no immediate or obvious workaround for this limitation.

 

Resolution

To resolve this, modify the hostname for the machine using cloud-init at deployment time.

Documentation on leveraging cloud-init can be found here:
https://techdocs.broadcom.com/us/en/vmware-cis/aria/aria-automation/8-14/assembler-on-prem-using-and-managing-master-map-8-14/maphead-designing-your-deployments/initialize-general/initialize-cloudconfig-commands.html

An example of the commands used to accomplish this are in the "runcmd" block included below:

cloudConfigSettings:
      cloudConfig: |
        #cloud-config
        runcmd:
          - sed -i "s/.local /   /g" /etc/hosts
          - hostnamectl set-hostname `hostname | sed 's/.local//g'`

  Issue with Aria Automation Custom form Multi Value Picker and Data Grid https://knowledge.broadcom.com/external/article?articleNumber=345960 Products VMware Aria Suite Issue/Introduction Symptoms: Getting  error " Expected Type String but was Object ", w hen trying to use Complex Types in MultiValue Picker on the Aria for Automation Custom Form. Environment VMware vRealize Automation 8.x Cause This issue has been identified where the problem appears when a single column Multi Value Picker or Data Grid is used. Resolution This is a known issue. There is a workaround.  Workaround: As a workaround, try adding one empty column in the Multivalue picker without filling the options. So we can add one more column without filling the value which will be hidden(there is a button in the designer page that will hide the column). This way the end user will receive the same view.

  The Guardrails of Automation VMware Cloud Foundation (VCF) 9.0 has redefined private cloud automation. With full-stack automation powered by Ansible and orchestrated through vRealize Orchestrator (vRO), and version-controlled deployments driven by GitOps and CI/CD pipelines, teams can build infrastructure faster than ever. But automation without guardrails is a recipe for risk Enter RBAC and policy enforcement. This third and final installment in our automation series focuses on how to secure and govern multi-tenant environments in VCF 9.0 with role-based access control (RBAC) and layered identity management. VCF’s IAM Foundation VCF 9.x integrates tightly with enterprise identity providers, enabling organizations to define and assign roles using existing Active Directory (AD) groups. With its persona-based access model, administrators can enforce strict boundaries across compute, storage, and networking resources: Personas : Global Admin, Tenant Admin, Contributor, Viewer Projec...
