This is a post that takes the previous Nexus EVPN VXLAN Fabric and the Nexus EVPN VXLAN Fabric using Ansible posts, and uses the GitLab pipeline to perform the automation. In a previous post, I have walked through the setting up GitLab for CI/CD pipelines with external runners. For this GitLab project, I am using

If you already have ACI running and then want to move to a DevOps approach and bring that configuration into Terraform, how can that be performed? The ACI Terraform provider supports importing configuration. All that is required is the resource and name of that resource. In the following example, I will use the Cisco ACI

In my previous ACI automation post, I used Terraform and the credentials were in plain text inside the main.tf file. I have updated this, so the credentials are stored in GitLab environment variables, which is a much more secure method. The process of the credentials from GitLab to Terraform are as follows; Create Environment Variables

In a previous post, I have created a sample of FortiGate config with Terraform. This was all performed locally from a Windows machine. While this is good in a lab environment, the major problem with it is that the management doesn’t scale. If there is more than a single network engineer, they need to share

After setting up the GitLab CI/CI pipeline, the next step I wanted to take is to use Terraform to make changes to AWS infrastructure. There are several steps to configure a GitLab pipeline for Terraform. This example is for a new project with nothing yet configured in AWS yet. Create a New Project in GitLab

DevOps principles are becoming very popular in the networking space. In this post, I will demonstrate how to setup a GitLab pipeline using your own GitLab Runner. By default, GitLab does have public runners that perform the same tasks. Overview In GitLab, a pipeline is a series of stages and jobs defined in a .gitlab-ci.yml

Cisco ACI Supports several methods of automation or infrastructure as code. For this example, I will be using Terraform to give examples of setting up different fabric policies using the Cisco ACI lab. Setup To get this setup, I have several things to do Lab Once the lab has been setup and VPN connected to
