THIS REPOSITORY IS NO LONGER USED! Please see sms-compose for information on building and deploying the VIP SMS app.



Automate the testing & creation of Infrastructure for the VIP SMS app.

This project uses Terraform to control AWS infrastructure (ie, load balancers, so many worker nodes, security groups, etc), and ansible to create AMI images for the servers that run the web and worker processes (ie, install ruby, gems, other server infrastructure). If you need to update the base web or worker images because of new libraries or new keys, you build them with the rake tasks outlined below, get the current terraform state with the get_tfstate task, and then run the terraform rake task, and then upload the new terraform state at the end.

To deploy new versions of either the web or worker apps, you use the deploy tasks from those projects, see their readmes.



Development System Setup

To set your system up to develop this application...

  1. Make sure you have everything from the requirements section 2, For terraform, download the version for your platform and add the executables to your PATH
  2. Run bundle


Modify The Web / Worker Image

  1. Make modifications to the ansible script (the files in /roles), or the infrastructure recipes in
  2. Test locally using vagrant
    • Run vagrant up if your VMs do not exist
    • Run vagrant reload --provision if your VMs do exist
  3. Use the rake command specified below to build new images
  4. Replace the appropriate ami ids in the Infrastructure.tfvars file
  5. Run rake get_tfstate\[bucket\] to get the latest tfstate (bucket is usually named vip-sms-terraform)
  6. Run rake terraform
  7. Run rake upload_tfstate\[bucket\] to upload the new tfstate


Run Terraform

rake terraform
  • Run terraform apply with the AWS credentials in your .env file
  • Create AWS SQS queues
  • Create AWS DynamoDB databases

Upload Latest tfstate File To S3

rake upload_tfstate\[bucket\]
  • Unmark the previous latest terraform.tfstate file as latest
  • Upload the new terraform.tfstate file marked as latest

Get The Latest tfstate File From S3

rake get_tfstate\[bucket\]
  • Move the current terraform.tfstate file (if it exists) to terraform.tfstate.old
  • Download the latest terraform.tfstate file from S3

Build New Web Image

rake build_web_image\[environment\]
  • Spin up a new AWS EC2 instance
  • Run the Ansbile script on it
  • Stop the instance
  • Create an AMI
  • Terminate the instance

Build New Worker Image

rake build_worker_image\[environment\]
  • Spin up a new AWS EC2 instance
  • Run the Ansbile script on it
  • Stop the instance
  • Create an AMI
  • Terminate the instance
