How to view the mac address of the virtual machine copied by centos7 requires "ip addr" to output similar information as ~]# ip addr The solution (because there is no les file in centos7, the replicated virtual machine (vmware) needs to modify the mac address) is to modify the mac address.Ĥ.

Troubleshooting Terraform… can be a challenge.
It’s Infrastructure as Code, written in JSON or in HCL (HCL is the HashiCorp configuration language).It’s designed to build, change, version, infrastructure across multiple providers – AWS, Azure, Google Cloud, vSphere, OpenStack, etc….Others are Vagrant, Packer, Vault, Consul, Nomad. Also Ryan in my team documented using Terraform on VMC on AWS in his blog. Thanks to Gilles and Prabhu for introducing me to Terraform a few years ago. Terraform expands on this by not only deploying virtual machines but also storage, networking and security entities across multiple infrastructures, clouds and vendors.
Packer provided the ability to create and manage virtual machines from a template written as a code (in JSON format). Terraform is another tool offered by HashiCorp (I covered Packer in a previous post).
