The services service exposes management endpoints to the instance's microservices, notably the Collector and Archivist microservices. These endpoints are used to coordinate the microservice-managed aspects of the log stream lifecycle.
The static service hosts static content, including:
Similar to other LUCI GAE apps:
cd coordinator gae.py upload -A luci-logdog-dev gae.py switch -A luci-logdog-dev # Or if you want to update a single module only, e.g. "logs". gae.py upload -A luci-logdog-dev logs
