Pinpoint Web UI

This directory contains the Go backend for the Pinpoint Web UI.

Running Locally

To build and run the Go server directly without Docker:

bazelisk run //pinpoint/go/webui -- --port=:8000

Local Deployment with Docker

1. Build and Load the Container

The skia_app_container macro automatically generates a load_<name> target that builds the OCI image and loads it into your local Docker daemon.

Run the following command:

bazelisk run //pinpoint:load_pinpoint_webui

2. Run the Container

Once loaded, you can run the container using standard Docker commands. The image is tagged as gcr.io/ followed by the repository attribute defined in your BUILD.bazel.

docker run -p 8000:8000 gcr.io/skia-public/pinpoint_webui:latest

3. Verify

Access the service in your browser at: http://localhost:8000

401 Unauthorized Error

If you see an error like GET returned 401 Unauthorized when fetching @base-cipd (or any other gcr.io image), it is an authentication issue.

Fix: Re-authenticate and Configure Docker

Run the following commands in your terminal:

1. Login to gcloud: bash gcloud auth login
2. Set up Application Default Credentials (ADC): bash gcloud auth application-default login
3. Configure Docker to use gcloud as a credential helper: Bazel and rules_oci often rely on your Docker configuration to authenticate with GCR. bash gcloud auth configure-docker gcr.io
