Delete All S3 Object Versions

Use this script to delete all object versions in a S3 bucket. For very large object version counts it may be more effective to use Object Lifecycle Management instead to expire versions.

Usage

python delete-object-versions.py (s3-bucket-name)

Background

I may have let Arch go months without updates before. Its not advisable to apply them on a schedule either.

Solution

Providing regular prompts to apply updates seems like the best solution.

Schedule Download of Packages

This cronjob will download packages and cache locally. Put into root's crontab or run via sudo.

Apex Record Redirects

An apex (or root) record of a zone cannot be a CNAME by specification. This has implications for domains that try to integrate with virtually any cloud platform (AWS, Azure, Heroku, etc.). A common pattern to mitigate this issue is to perform a HTTP 301 redirect from the apex record to a subdomain (usually www.domain.com).

On the other hand, using a single cloud provider for DNS and underlying infrastructure may yield proprietary solutions. For example, AWS provides a Route 53 alias record which can be used at the zone apex.

Alexa Script

To understand the prevalence of the apex redirect pattern this script will test the top 1000 Alexa rank domains (as of 3/11/16).

Ansible Vault Environment Variable

Per http://docs.ansible.com/ansible/playbooks_vault.html you can set an environment variable to use a password file for vault access. We can use this to create an environment variable to hold the password.

Password Script

Copy vault-env from this project to ~/bin. Then add this to your ~/.bashrc:

export ANSIBLE_VAULT_PASSWORD_FILE=~/bin/vault-env
