A Blog about my adventures in the cloud.

  • Deleting many files from the Linux Command Line

    I’ll admit that this post is more for me than any of my readers. I have this command that is buried in my notes and always takes me forever to dig back out. I figured I’d publish it on my blog so that I would maybe commit it to memory. Let’s say that you have…

  • EC2 Reservation Notification

    I realized today that I haven’t updated my EC2 reservations recently. Wondering why I never did this I came to understand that there was no way that I was getting notified that the reservations were expiring. I spent the day putting together a script that would look through my reservations, assess the time of their…

  • Adding a Standard Bucket Policy

    It is good practice to deny traffic that is not HTTPS to your S3 bucket. For this reason, I wrote a script that I can use to apply a standard policy to each of my S3 buckets. While the script could be more robust to iterate through each bucket in my account, I decided to…

  • Security Group ID Finder

    Security Group ID Finder

    I have been working on deploying resources to a lot of AWS accounts lately where each account has the same network infrastructure. When deploying Lambdas, I had the common name of the security group but not the ID. I wrote this utility to get the security group ID for me quickly. This is a simple…

  • A Dynamo Data Migration Tool

    A Dynamo Data Migration Tool

    Have you ever wanted to migrate data from one Dynamo DB table to another? I haven’t seen an AWS tool to do this so I wrote one using Python. The process is pretty simple. First, we get all of our data from our source table. We store this in a list. Next, we iterate over…

  • Querying and Editing a Single Dynamo Object

    I have a workflow that creates a record inside of a DynamoDB table as part of a pipeline within AWS. The record has a primary key of the Code Pipeline job. Later in the pipeline I wanted to edit that object to append the status of resources created by this pipeline. In order to do…

  • Searching S3 Buckets for an Object

    I wrote this code for a project that I was working on for a client. The goal was to look in an S3 bucket to find objects that match a specific identification number. Specifically, they are looking to return audio logs from calls in an AWS Connect instance. In this script, we are utilizing Boto3…

  • Subscribing All SES Identities to an SNS Topic

    I recently ran across an issue where I was experiencing many bounced emails on my Amazon SES account. So much so that Amazon reached out and put me on a warning notice. I realized that I had no logging in place to handle this. In order to create a logging mechanism I decided to send…

  • Building Dynamic DNS with Route53 and PFSense

    I use PFSense as my home router, firewall, VPN and much more. I’m sure a lot of my readers do as well. One thing that I have always set up is an entry in Route53 that points to my public IP address on my PFSense box. However, I use Comcast so, my IP address is…

  • Setting the Starting Directory for Windows Subsystem for Linux

    I use Windows Subsystem for Linux almost every day. I run Ubuntu 20.04 for almost all of my development work. I recently re-installed Windows because I upgraded my PC after many years. One thing that has always bothered me is that when you launch WSL for the first time it doesn’t put you into your…
