GitHub action to deploy anything into a bucket, adding the options to add a CDN and use a Domain (if hosted in Route53) with certificates.

This action will copy the files from the defined folder into an S3 bucket, defining the content type and serving ALL OF THEM PUBLICLY.

graph TD;
    A[S3 Bucket] --> B[S3 Endpoint]
    A -->|DNS| C[Direct S3 DNS] --> G[- No SSL\n- 63 chars FQDN limit]
    A -->|CDN| D[CDN Public URL] --> H[- SSL\n- CND URL]
    A -->|CDN + DNS| E[Public FQDN] --> I[- Owned SSL cert\n- Unlimited FQDN length]

1. Files to publish
2. An AWS Account
3. If domain and cert wanted, registered domain in AWS.

Will grab everything defined in aws_site_source_folder and push it to a bucket.

Define aws_site_root_object if different than index.html.

You'll need Access Keys from an AWS account

If aws_r53_domain_name is defined, we will look up for a certificate with the name of that domain (eg. example.com). We expect that certificate to contain both example.com and *.example.com.

Setting aws_r53_create_root_cert to true will create this certificate with both example.com and *.example.com for you, and validate them. (DNS validation).

Setting aws_r53_create_sub_cert to true will create a certificate just for the subdomain, and validate it.

✅ If using aws_r53_create_sub_cert the total length of the FQDN cannot exceed 64 characters. Use aws_r53_create_root_cert or specify one by setting aws_r53_cert_arn.

⚠️ Be very careful here! Created certificates are fully managed by Terraform. Therefor they will be destroyed upon stack destruction.

Create .github/workflow/deploy.yaml with the following to build on push.

name: Basic deploy
on:
  push:
    branches: [ main ]

jobs:
  Deploy-static-site:
    runs-on: ubuntu-latest

    steps:
    - name: Create deploy-bucket
      uses: bitovi/github-actions-deploy-static-site-to-aws@v0.2.1
      with:
        aws_access_key_id: ${{ secrets.AWS_ACCESS_KEY_ID }}
        aws_secret_access_key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
        aws_default_region: us-east-1

        tf_action: 'apply'
        tf_state_bucket_destroy: true # If destroying, will remove the bucket
        
        aws_site_cdn_enabled: true
        
        aws_r53_domain_name: example.com # You should own and have this domain available in R53
        aws_r53_sub_domain_name: site
        aws_r53_create_sub_cert: true # Will create and validate a cert for this sub-domain

1. Action defaults
2. AWS
3. Terraform options
4. SITE Settings
5. Certificate

The following inputs can be used as step.with keys

Most resources will contain the tag ${GITHUB_ORG_NAME}-${GITHUB_REPO_NAME}-${GITHUB_BRANCH_NAME}, some of them, even the resource name after. We limit this to a 60 characters string because some AWS resources have a length limit and short it if needed.

We use the kubernetes style for this. For example, kubernetes -> k(# of characters)s -> k8s. And so you might see some compressions are made.

For some specific resources, we have a 32 characters limit. If the identifier length exceeds this number after compression, we remove the middle part and replace it for a hash made up from the string itself.

As a default, the bucket name will be ${GITHUB_ORG_NAME}-${GITHUB_REPO_NAME}-${GITHUB_BRANCH_NAME}-sp.

But, in the case you add a Route53 domain and no CDN, the bucket name must match the FQDN defined, like site.example.com. If setting aws_r53_root_domain_deploy, two buckets will be created. www.{aws_r53_domain_name}and {aws_r53_domain_name}. Traffic from www bucket will be forwarded to the main bucket. Because of this reason, the length of the FQDN MUST be below 64 characters. Will try using the provided FQDN, if none provided, fallback to resource-identifier.{aws_r53_domain_name} of the compressed one. IF it still exceeds the limit, will remove as many as needed.

⚠️ HTTPS (TLS / SSL) will only be available if using CDN.

In the case you are using domains and not using a CDN, no cert will be available, and length of the FQDN MUST be below 64 characters. Will be adjusted if it exceeds that limit.
