ec2init.sh

Bootstraps an Amazon Linux 2023 EC2 instance with AWS, Terraform, Kubernetes, database, and Docker tooling.

What the Script Does​

The current script in static/ec2init.sh:

  • Appends Terraform and kubectl aliases to ~/.bashrc
  • Installs system packages with yum
  • Installs AWS CLI v2
  • Installs kubectl, eksctl, helm, and k9s
  • Adds ec2-user and ssm-user to the Docker group
  • Enables Docker and registers binfmt support for multi-arch containers
  • Creates a binfmt-qemu systemd service so multi-arch support survives reboot

Quick Install​

curl -fsSL https://awsutils.github.io/ec2init.sh | bash

Intended Environment​

  • Amazon Linux 2023
  • EC2 instance with root privileges
  • Internet access for package and binary downloads

Major Packages and Tools​

  • System packages: jq, curl, wget, git, docker, mariadb1011, postgresql17, redis6
  • AWS tooling: AWS CLI v2

Notes​

  • This script is tailored to Amazon Linux 2023 package names and service behavior
  • It appends to ~/.bashrc every time you run it
  • Docker group membership usually requires a new login before it takes effect
