Networking in GCP, or any cloud environment, often requires a load balancer(LB). If you try to use Terraform to deploy a load balancer in GCP you’ll notice that there is not a single Terraform resource to create a GCP LB. GCP provides example Terraform scripts to create LBs in their documentation here. However, if you have an understanding of how load balancers work internally, and how to properly structure your Terraform code, creating your own LB modules in GCP using Terraform is possible. This can allow you to configure your LBs to do exactly what you need. ...

In this post: What is Ansible Installing Ansible Authentication Inventories Playbooks Testing Ansible What is Ansible? Ansible is an open-source infrastructure as code tool provided by Red Hat. Instead of agents, Ansible relies on SSH to pass tasks defined in YAML to remote machines. To get familiar with Ansible, I created a simple scenario where a bash script needed to be uploaded to a remote machine and ran periodically. ...

Introduction to Terraform Terraform by Hashicorp is a “tool for building, changing, and versioning infrastructure safely and efficiently”. Terraform works using infrastructure as code, meaning that build a blueprint of the resources you need in a configuration file (with the .tf extension) and Terraform builds that infrastructure for you. The Terraform package itself is a single binary file, easily downloaded, and is used to build/edit/destroy your resources. In contrast to older versions of infrastructure build tools like Packer, Terraform allows you to create infrastructure across multiple cloud providers and is “smart” enough to know how many more machines to create in context of what you already have. For example, if you have 5 servers on Azure, but you want 10, Terraform will build 5 more for you to bring you to a total of 10 versus building 10 more servers and leaving you with 15. ...
