+# Live Deploy
+
+Current deployment details for https://perl5.test-smoke.org/ are as follows, this project is
+currently hosted by the MetaCPAN team.
+
+## Contacts:
+
+- irc.perl.org - #smoke and #metacpan channels
+
+## K8s setup
+
+- [K8s setup](https://github.com/metacpan/metacpan-k8s/tree/main/apps/test-smoke)
+  - [Container deployments](https://github.com/metacpan/metacpan-k8s/blob/main/apps/test-smoke/base/deployment.yaml), one for `API` and one for `web` front end.
+    - Github actions build the containers from the relevant web/api repo
+  - [Ingress setup](https://github.com/metacpan/metacpan-k8s/blob/main/apps/test-smoke/environments/prod/ingress.yaml) notes:
+    - Special `proxy-body-size: 8m` rule to allow up to 8mg report payloads, otherwise nginx returns a 413 (Content too large)
+    - `/api/` url used to send to API service/deployment
+
+## Important Notes:
+
+### SQL:
+
+- DB name: coresmokedb
+- DB user: coresmokedb
+- Schema: public
+
+Deploy a fresh DB from either the backup
+or [coresmokedb.sql](https://github.com/metacpan/Perl5-CoreSmokeDB/blob/main/coresmokedb.sql) - you should make sure to use the latter to create the indexes
+
+### Old API /reports vs new api /api/reports
+
+Most users are on versions of [Test::Smoke](https://metacpan.org/pod/Test::Smoke)
+less than 1.81 (released 2023-10-27) with no way to contact them. This means they 
+use the old `/report` URL and not `/api/report`.
+
+This was a problem because the way we direct traffic to the API
+container in k8s is by looking for `/api` in the url path. This is solved by using Fastly CDN and the following VCL snippet:
+
+```vcl
+# Backwards compatability with old clients
+if (req.url.path ~ "^/report" && req.method == "POST") {
+  set req.url = regsub(req.url, "^/report", "/api/old_format_reports");
+}
+```
+
+If this service is deployed in any other way this issue will have to be resolved differently. 
+
+### Database Backups
+
+- The MetaCPAN team takes nightly database backups and saves to https://backblaze.com - storing the last 5 days before rotating.
+
+### Logs
+
+- Fastly (CDN) logs are streamed to [Honeycomb](https://ui.honeycomb.io/metacpan/environments/testsmoke/datasets/testsmokelivedata/overview) which the MetaCPAN team has access to. NOTE: we can see which version of `Test::Smoke` is submitting each request, and indeed it's logged in the DB as well.
