How to forcibly delete an NSX-T 3 Segment

I recently ran in to a problem where i couldnt delete an NSX segment so i went exploring the API. The API guide can be found here

The method used is delete policy/api/v1/infra/segments/{segment-id}?force=true

It would look like this in Postman:

To list the segments we can use a get request towards /policy/api/v1/infra/segments/

Removing NSX stale packages from ESXi host

I recently ran in to a problem where i wanted to perform a clean configuration of one of my ESXi hosts from an NSX perspective, however i ran in to a problem where NSX was reporting that the packages are already installed. To fix the issue i had to run the following to list the packages installed:

esxcli software vib list | grep -i nsx

Once i had the list all i had to do is uninstall them using:

esxcli software vib remove -n packagename1 -n packagename2 ...

Once the uninstall was complete i was able to redeploy NSX from the NSX Manager

Configure NSX-T to use vIDM as authentication

I needed to create a few additional accounts in NSX-T for outside sources. Instead of creating individual accounts i wanted to use the existing ones from AD.

To get started we need to get the certificate from the vIDM server. Log on to the vIDM server as root and run the following:

openssl1 s_client -connect <FQDN of vIDM host>:443 < /dev/null 2> /dev/null | openssl x509 -sha256 -fingerprint -noout -in /dev/stdin

Next we need to create the OAuth client ID in vIDM. Log in to the vIDM UI using the url <FQDN of vIDM host>SAAS/admin/app/page#!/dashboard as admin and Navigate to Catalog -> Settings

Navigate to Remote App Access -> Clients -> Create Client

In the Access Type chose Service Client Token, Client ID can be anything. Under Advanced click on Generate Shared Secret (take a note of this because we need it on the NSX side)

Next, log in to the NSX-T cluster and go to System -> Users and Roles -> VMWARE IDENTITY MANAGER -> Edit

Next fill in all the required fields with the existing data that we generated in the previous steps

Next we can see the integration as enabled and the connection as up

Next we can go to USERS click on ADD -> Role Assignment for VIDM

As you type in a user the system will try to auto complete it

Once the users and groups are defined all is left is to test out the authentication and validate that everything works

Differences between SaltStack and Terraform

Infrastructure management has come a long way in recent years, with a variety of tools and frameworks available to help you provision, configure, and manage your infrastructure. Two popular tools in this space are SaltStack and Terraform, but they serve different purposes and have different strengths. In this post, we’ll explore the differences between SaltStack and Terraform, and when you might choose one over the other.

SaltStack: Configuration Management

SaltStack is a configuration management tool that allows you to define and apply a set of configurations or settings to a group of servers or other infrastructure components. Configuration management is an important aspect of infrastructure management because it ensures that all servers and systems in your infrastructure are consistent and conform to a known configuration. This can help with security, reliability, and troubleshooting.

SaltStack is designed to be highly scalable and flexible, with the ability to manage tens of thousands of servers at once. It uses a master-minion architecture, where a central Salt master node sends commands and configurations to individual Salt minion nodes on each server. This allows you to manage a large number of servers from a single central location.

SaltStack allows you to define configuration states in a declarative way, using a domain-specific language called Salt State. With Salt State, you define the desired state of each server, including packages, files, services, and other configurations. SaltStack then applies those states to the appropriate servers, ensuring that they conform to the desired configuration.

One of the strengths of SaltStack is its ability to handle complex configurations and dependencies. SaltStack allows you to define relationships between different configurations, so that dependencies are automatically resolved and configurations are applied in the correct order. This can be especially useful in large and complex infrastructures, where dependencies between configurations can be difficult to manage manually.

SaltStack also has a large and active community, with many modules and plugins available to extend its functionality. This can be helpful if you need to customize SaltStack to meet your specific needs.

Terraform: Infrastructure Provisioning and Management

Terraform, on the other hand, is a tool for infrastructure provisioning and management. It allows you to define and deploy infrastructure resources such as servers, networks, and storage in a variety of cloud and on-premises environments. Terraform is designed to be infrastructure-as-code, meaning you define your infrastructure in a text file and use Terraform to create and manage those resources.

Terraform uses a declarative configuration language called HashiCorp Configuration Language (HCL) to define your infrastructure. With HCL, you define the desired state of your infrastructure, including the resources you want to create, their configuration settings, and any dependencies between resources. Terraform then creates and manages those resources, ensuring that they conform to the desired configuration.

One of the strengths of Terraform is its ability to manage infrastructure resources across a wide range of environments, including public and private clouds, on-premises data centers, and even edge computing environments. Terraform has a large number of providers available that allow you to provision and manage resources in popular cloud providers such as AWS, Azure, and Google Cloud Platform, as well as other infrastructure environments such as Kubernetes, VMware, and OpenStack.

Another strength of Terraform is its support for infrastructure versioning and collaboration. Because you define your infrastructure as code, you can use version control tools such as Git to track changes to your infrastructure over time. This makes it easier to collaborate with other team members and to revert changes if necessary.

Choosing Between SaltStack and Terraform

So, when should you choose SaltStack over Terraform, and vice versa? The answer depends on your specific needs
