Backend Storage When I discussed using Terrform with AWS I made a blog … Continue reading Terraform and Azure (Infrastructure as Code) – Part 3
Changing Azure Subscriptions In part 1 I discussed logging into Azure using Azure CLI and noting the default subscription, as that is where Terraform will deploy resources to. However, you may have multiple Azure subscriptions and want to deploy to one that is not the default. This can be accomplished using the Azure CLI: This … Continue reading Terraform and Azure (Infrastructure as Code) – Part 2
During Summer 2020 I wrote a few blog posts about Terraform and gave a few examples in my geektechstuff AWS environment. Over the Autumn and Winter of 2020, and the Spring of 2021 I expanded my Terraform knowledge and experience a lot, and one of the points I think I need to blog about is … Continue reading Terraform and Azure (Infrastructure as Code) – Part 1

Following on from my previous blog post which looked at installing Terraform, I am now going to look at using Terraform to deploy an AWS EC2 instance. Terraform uses Infrastructure as Code (IaC) and so it needs a terraform file containing the details of what the expected infrastructure should be. Note: To follow along with … Continue reading Terraform – Introduction: TF files / First Run

I have used previous blog posts to discuss using Ansible to create / manage AWS EC2 instances, and using Terraform with Ansible to create / manage AWS EC2 instances. However, there are people that prefer to use the AWS web console over Infrastructure as Code (IaC). If you find yourself in the situation of creating … Continue reading AWS – EC2 User Data: Preparing Ubuntu Instance For Ansible Management (AWS / Ansible)
AWS EC2 instances can be powered off (or on) via a few lines of Python and the Boto3 library. Below is an example I’m currently playing about with. The instances segment filters on all EC2 instances that are running and contain a tag of “office_hours”, great to run at the end of the day to … Continue reading Powering Off AWS EC2 Instances via Tags (Python)
