# Architecture — Nginx + upload-sidecar
|
|
|
|
> gitea-reports on korvattu. Uusi arkkitehtuuri: Nginx palvelee staattisia tiedostoja PV:ltä, upload-sidecar (busybox httpd + CGI) ottaa vastaan tar.gz-PUTit.
|
|
|
|
## Yleiskuvaus
|
|
|
|
Yksi apex-host, monta Gitea-repoa. URL = FS-polku: `/{owner}/{repo}/{branch}/{sha8}/{suite}/`.
|
|
Ei Host-header-kikkaa, ei slugia, ei rewritea.
|
|
|
|
## Komponentit
|
|
|
|
| Komponentti | Rooli |
|
|
|-------------|-------|
|
|
| **nginx** | Palvelee staattisia tiedostoja /app/data -rootista (:8080) |
|
|
| **upload** (Python HTTP server) | Vastaanottaa PUT /path + tar.gz body, purkaa PV:lle (:8081) |
|
|
| **PVC** | Raporttisisältö suoraan FS-muodossa |
|
|
| **Service** | ClusterIP :8080 (read), :8081 (write) |
|
|
| **Traefik IngressRoute** | PATCH/PUT → upload:8081 (BasicAuth), GET/HEAD → nginx:8080 |
|
|
| **Traefik Middleware** | `gitea-reports-publish-auth` (BasicAuth), HTTPS-redirect |
|
|
| **cert-manager Certificate** | TLS |
|
|
|
|

|
|
|
|
## Julkaisu
|
|
|
|
1. Julkaisija paketoi tiedostot tar.gz:ksi
|
|
2. `PUT https://{host}/{owner}/{repo}/{branch}/{sha8}/{suite}/`
|
|
3. Traefik tarkistaa BasicAuth → välittää upload-sidecarille
|
|
4. CGI purkaa tar.gz:n suoraan PV:lle: `/app/data/{owner}/{repo}/{branch}/{sha8}/{suite}/`
|
|
|
|
## Luku
|
|
|
|
1. Selain avaa URL:n (GET/HEAD)
|
|
2. Traefik välittää nginxille
|
|
3. Nginx palauttaa suoraan PV:ltä
|
|
|
|
## Retention
|
|
|
|
CronJob lukee PV:tä suoraan (find, ls, stat), tarkistaa branchin olemassaolon Giteasta, poistaa vanhat commit-kansiot.
