  • Coderwall | Dump all variables – For debugging purposes it can be useful to not just dump hostvars but also all other variables and group information. You can do this using a jinja template which you could include in a debug task
  • Using Ansible to create AWS instances | Tivix – Ansible is a great tool for enhancing productivity. With a vast array of modules to choose from, it can save you a lot of time by automating away common tasks. At Tivix we use it for single-command deployment, with the most common destination being Amazon EC2 instances created beforehand. Since Ansible is capable of managing EC2 resources, we can improve this setup by making a playbook to create an instance for us.

  • : establishing geek cred since 1305712800 – Setting up an EC2 instance on AWS used to be as straightforward as provisioning a machine and SSHing into it. However, this process has become a bit more complicated now that Amazon VPC has become the standard for managing machines in the cloud.
  • Set up public and private subnets using AWS VPC — Mike Melnicki’s Blog – This is a step-by-step guide on how to set up public and private subnets for running a service on an internal network within AWS. This guide will also set up a bastion host (or jump host) and show you how you can easily ssh in to the hosts within your private subnet via the bastion host. All of this stuff can be done via the AWS web console, but I thought it would be helpful to show the specific commands and provide some commentary about what is happening on each step.
  • WordPress Checklist (Infographic): 101 Easy Steps to Follow. – It’s a big struggle in remembering the steps involved in setting up a WordPress website.

  • Monitoring EC2 Memory and Disk Usage In CloudWatch Using Custom Metrics | Celingest Blog – Feel the Cloud – With CloudWatch we can track and monitor a lot of metrics across many AWS’s products and set alarms when certain conditions are met. When these alarms are triggered, they can notify us or automate actions such as shrinking or increasing an AutoScaling Group capacity. CloudWatch knows a lot about our EC2 instances’ at the hardware level but it lacks the software’s point of view. In this post we will explain how to use CloudWatch to monitor important resources it can’t monitor by default.
