Deployments are automatically performed on GitHub Actions on master branch after CI.
- App Runner: arn:aws:apprunner:us-west-2:005216166247:service/rko-router/2c9219ae5e14411baaf46fa932f33025
- CloudFront: arn:aws:cloudfront::005216166247:distribution/E2WEWQCYU12GVD
All resources except App Runner deployment is managed under Terraform (./tf).
Due to the quota of custom domains per App Runner service, the first hop on rko-router proxies a request to itself with correct Host header.
x-rko-host and x-rko-xfp headers are referenced as a Host and X-Forwarded-Proto header for the second hop.
These custom headers are assigned at CloudFront function (viewer-request) and implementation is at ./tf/cf_functions/src/viewreq.ts.
