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
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
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…
Pandas & NumPy with AWS Lambda
Fun fact: Pandas and NumPy don’t work out of the box with Lambda. The libraries that you might download from your development machine probably won’t work either. The standard Lambda Python environment is very barebones by default. There is no point in loading in a bunch of libraries if they aren’t needed. This is why…
A File Management Architecture
This post is a continuation of my article: “A File Extraction Project”. This project has been a great learning experience for both frontend and backend application architecture and design. Below you will find a diagram and an explanation of all the pieces that make this work. The entire architecture is powered by Flask on an…
A File Extraction Project
I had a client approach me regarding a set of files they had. The files were a set of certificates to support their products. They deliver these files to customers in the sales process. The workflow currently involves manually packaging the files up into a deliverable format. The client asked me to automate this process…
A Self Hosted Server Health Check
I’m not big on creating dashboards. I find that I don’t look at them enough to warrant hosting the software on an instance and having to have the browser open to the page all the time. Instead, I prefer to be alerted via Slack as much as possible. I wrote scripts to collect DNS records…
Where Is It 5 O’Clock Pt: 4
As much as I’ve scratched my head working on this project it has been fun to learn some new things and build something that isn’t infrastructure automation. I’ve learned some frontend web development some backend development and utilized some new Amazon Web Services products. With all that nice stuff said I’m proud to announce that…
Where Is It Five O’Clock Pt: 3
So I left this project at a point where I felt it needed to be re-architected based on the fact that Flask only executes the function once and not every time the page loads. I re-architected the application in my head to include an API that calls the Lambda function and returns a list of…
