Creating AWS EC2 t3 nano with Apache using Terraform.⌗
This code generating an EC2 instance with IPv6 networking with an SSH key copied from the source server. It uses SSM for local access, copying content from a local S3 bucket to populate the /data/sites directory which Apache then serves up. I’ve not published the Apache configuration files here.
I had some problems with t3.nano OOMs during startup, so the userdata adds a temporary 1GB swapfile in the userdata.sh at the start so that the userdata.sh completes.
dd if=/dev/zero of=/var/cache/swapfile bs=1M count=1024; chmod 600 /var/cache/swapfile; mkswap /var/cache/swapfile; swapon /var/cache/swapfile; free -m > /var/tmp/swap.txt
It then removes the swapfile at the end of the userdata, but leaving this in place would probably prevent OOMs.
