feat(dev): Add SENTRY_CELL_ROUTING env var that runs cell-routing mode locally#115852
Merged
Conversation
When set, configures the dev server so cell-scoped API XHRs
(/api/0/organizations/{slug}/*) target Synapse on :13000 while UI
rendering and control API stay on the sentry devserver at :8000.
Flips system:multi-region and points system.region-api-url-template at
the Synapse port so the frontend's regionUrl bootstrap picks it up.
Should be run together with devservices --mode cell-routing for the
matching Synapse proxy/ingest-router containers.
Updates agent skill with information about how to run cell-routing
mode.

With this flag on sentry is going to want to be run in siloed mode and I think behind ngrok.

i wasn't using ngrok in my testing, it doesn't seem to be required
