    Ok, Packer

    After manually installing Nomad, Docker, Git, and ZSH on 3 EC2 instances, it was time to see if Packer could automate the process for me.

    Deploying a GraphQL Docker Container to AWS Lambda with Waypoint

    I finally got around to ticking off a few items on my todo list.

    1. Shoving an express.js app into a lambda function.
    2. Deploying a Docker container to lambda.
    3. Using a new HashiCorp product.

    ...And it all required very little code. Sort of.

    Infrastructure as Code To Save Time

    I found myself repeating some tedious tasks within the AWS console, week after week, and wanted to stop suffering. Infrasructure-as-code was the way to go but I knew I didn't want to learn Cloud Formation, and I was too lazy to pick up yet another 3rd party tool like Terraform.
