kyxap1 / aggregate-cidr-addresses.pl
Created May 25, 2020 22:42 — forked from denji/README.md
Take a list of CIDR address blocks and combine them, for example, 192.168.0.0/24 and 192.168.1.0/24 gives 192.168.0.0/23. I usually use "list-iana-reserved-ranges | aggregate-cidr-addresses" to get a list of blocks to not report with firewall log processing.

terraform template to generate serverspec properties

This uses terraform's template_file resource to generate a yaml properties file for serverspec to use.

  • create the Rakefile in your terraform project root
  • create a spec directory and put spec_helper.rb in it
  • create the templates/properties.tmpl.yml file
  • create the serverspec.tf
  • terraform apply

tests

Tests will be matched based on roles defined for a given node.

Simple, semi-anonymous backups with S3 and curl

Backing stuff up is a bit of a hassle, to set up and to maintain. While full-blown backup suites such as duplicity or CrashPlan will do all kinds of clever things for you (and I'd recommend either for more complex setups), sometimes you just want to put that daily database dump somewhere off-site and be done with it. This is what I've done, with an Amazon S3 bucket and curl. Hold onto your hats, there's some Bucket Policy acrobatics ahead.

There's also a tl;dr at the very end if you just want the delicious copy-pasta.
