ui.perfetto.dev Cloud scripts

See go/perfetto-ui-autopush for docs on how this works end-to-end.

/appengine : GAE <> GCS proxy

The Google AppEngine instance that responds to ui.perfetto.dev. It simply passes through the requests to the bucket gs://ui.perfetto.dev . This should NOT be re-deployed when uploading a new version of the ui, as the actual UI artifacts live in GCS.

We are using AppEngine for historical reasons, at some point this should be migrated to a Type 7 Google Cloud Load Balancer, which supports direct backing by a GCS bucket. The only blocker for that is figuring out a seamless migration strategy for the SSL certificate.

/builder : Docker container for Google Cloud Build

Contains the Dockerfile to generate the container image which is used by Google Cloud Build when auto-triggering new ui builds. Cloud Build invokes the equivalent of:

docker run europe-docker.pkg.dev/perfetto-ui/builder/perfetto-ui-builder \
    /ui_builder_entrypoint.sh

NOTE: the ui_builder_entrypoint.sh script is bundled in the docker container. The container needs to be re-built and re-pushed if the script changes.

To update the container:

Prerequisite: Install the Google Cloud SDK from https://dl.google.com/dl/cloudsdk/release/google-cloud-sdk.tar.gz
