Heat is the main project in the OpenStack Orchestration program. We can use heat to automate security group implementation. If you have NSXv plugin integrated with your OpenStack environment, you can use Heat template to automate your NSX DFW rules implementation as well. Here I will show you how to use Terraform to do the …

To create a VM in OpenStack, you can use a Nova CLI as the below: nova boot --flavor SMALL4_2CPU_4GBRAM_80GBDISK --image rhel7 --nic net-id=eafea72a-c26e-4f73-826c-552da03cf532 myRHEL--availability-zone avz01 Except the name of the virtual machine, you need to find out all other requested parameters (flavor, image, net-id and availability-zone) so that you can use "nova boot". Please refer the CLI below …
Terraform can be used with Openstack for auto-provisioing. Today, I will shows a working Terraform example in Openstack. Firstly, define a Openstack provider for Terraform. Provider: provider "openstack" { user_name = "${var.openstack_user_name}" password = "${var.openstack_password}" tenant_name = "project1" auth_url = "http://keystone.openstack.com.au:5000/v3" domain_name = "DOMAINNAME" } Terraform currently support the following Openstack resource type: Compute, Network, …

In multi-tenants OpenStack environment, you possibly need to quickly find which project one VM belongs to. From CLI, I just found out a quick way. Step 1: [root@openstack RC]# nova list --all-tenants | grep 10.42.130.174 | 1c1c1051-2b28-47a6-9019-9ac2e3670587 | lnxau2004-001 | bc1dff54cfc841dfb8cc5b56e75d10e9 | ACTIVE | - | Running | sls1-dev-isd-waz001=10.42.130.174 From the output of Step 1, we …
