In the last post, I discussed the steps involved in installing AWS.Tools module for PowerShell on Amazon EC2 using user data and Terraform. This post lists the steps to install the AWS CLI on an Windows Amazon EC2 instance. I used Amazon EC2 user data and Terraform to automate AWS CLI installation as part of … Continue reading Install AWS CLI on a Windows Amazon EC2 instance using Terraform and user data
I was under the impression that all Amazon EC2 instances have the latest version of AWS CLI installed. So, I was in for a pretty shock when I discovered that is not always the case. However, I was required to use the AWS CLI, and since this was an Amazon EC2 with Windows OS, I … Continue reading Install AWS.Tools module for PowerShell on Amazon EC2 using user data and Terraform
If you have worked with Amazon EC2 user data, you'd have noticed a shortcoming in the approach -the inability to pass command-line arguments to the user data script at run time. Let me explain why I believe that to be a problem. User data is a capability associated with an Amazon EC2 instance as part … Continue reading Manage sensitive variables in Amazon EC2 user data with Terraform
I have a reasonable level of understanding of the relationship between AWS Identity and Access Management (IAM) policy, role, user, and group. I have also implemented the concept of assumed-role and the trusted and trusting account association. You can read more about that at -Creating IAM assume-role relationship between two AWS accounts. So, when I … Continue reading Attach IAM role to Amazon EC2 instance using Terraform
User data is a feature that allows customization of Amazon Elastic Compute Cloud (virtual machine) when it is created and (if desired) with each restart after being provisioned.As we all know, Amazon EC2 (virtual machines) is the legacy approach to hosting applications in the world of containers. Last year I attended a webinar sponsored by … Continue reading Working with Amazon EC2 user data and Terraform
One of the first components I created on the AWS cloud was an Amazon Elastic Compute Cloud (Amazon EC2) instance by watching hands-on tutorials. Little did I know about the infrastructure bits that went behind that. In this note, I list the AWS infrastructure and the configurations I created to host an Amazon EC2 instance … Continue reading Create Amazon EC2 using Terraform
A few weeks ago, I worked on a use case to create an Amazon EC2 instance from an Amazon Machine Image using Terraform. I had worked on that concept without automation, and my approach was to (i) identify an AMI and (ii) create an instance out of that AMI. I'll cover the network bits to … Continue reading Create an Amazon EC2 instance from an Amazon Machine Image (AMI) using Terraform
Terraform uses AWS IAM user credentials to manage resources in the AWS cloud. It does so by utilizing the secret key and access key of the IAM user. Hence, Terraform's ability to manage (create/update/delete) resources depend on the permission associated with the AWS IAM user. When I started working with Terraform to manage resources in … Continue reading Strengthen security posture with Terraform and AWS IAM to manage AWS cloud resources
A few months back, I came across an interesting concept of deploying infrastructure in a layered fashion, and I wish I had the URL saved to refer to it again. Nevertheless, the gist of the idea was that you could build an application product environment by deploying layer after layer of infrastructure. A layer of … Continue reading Terraform remote state file as a data source to support a layered IAC approach
A few weeks ago, I created a peering relationship between two Amazon VPCs that belonged to separate AWS accounts using Terraform. This note captures my learning from that exercise. But before I do so, let me briefly give an overview of VPC peering and then walk through the process of creating one. Per AWS, "Amazon … Continue reading VPC Peering using Terraform across separate AWS accounts
