terraform-example

A reference repo demonstrating how to continuously deploy via terraform from TravisCI.

Via TravisCI (or locally), use Node.js to compile a static website; use Terraform to:

create www.your-domain.com and your-domain.com AWS S3 buckets configured for static website hosting
redirect requests to the www.your-domain.com bucket to your-domain.com
deploy the index.html and error.html objects to the your-domain.com bucket
establish an AWS Route53 your-domain.com DNS zone
establish a Route53 A record set pointing your-domain.com to the your-domain.com S3 bucket

TravisCI build flow

TravisCI:

Uses Node.js to compile src to a static website.
If the branch is master, installs terraform
If the branch is master, executes deploy.sh to deploy the static website to AWS S3 website fronted by mikeball.me via:
terraform plan
terraform apply
commit terraform.tfstate back to this repo with a [ci skip] commit message such that a TravisCI build is not triggered.

To deploy your own:

$ gem install travis

Use the travis CLI to encrypt your AWS credentials and your Github access token in environment variables:

$ travis encrypt AWS_ACCESS_KEY_ID=123 AWS_SECRET_ACCESS_KEY=456 GH_TOKEN=123

Add the encrypted credentials string to your .travis.yml, replacing the current secure value:

...
  env:
    secure: "ENCRYPTED STRING HERE"
...

Replace GH_USER_NAME, GH_USER_EMAIL, and GH_REPO in the .travis.yml with your details.
Replace the domain var in terraform/main.tf with your domain name.
Remove my tfstate files to start fresh:

$ git rm terraform/terraform.tfstate*
$ git commit -m 'removed mdb tfstate'

$ git push origin master

Note that you may need to point the DNS servers associated with your-domain.com to those dynamically assigned to your A record by AWS. For example, my A record uses these DNS servers.
