 # php-apache
 
-Simple docker image to run latest apache with latest php (provided by arch)
+Arch Linux container image with Apache and PHP. It is the common runtime for
+the PHP sites hosted at brunner.ninja, including WordPress and phpPgAdmin.
+
+The image enables PostgreSQL and PDO PostgreSQL, GD for image thumbnails and
+responsive sizes, EXIF for photo metadata, Intl for locale-aware operations,
+and a production-sized PHP OPcache. Timestamp checks remain enabled so edits
+made through the browser-based development container and WordPress updates on
+the shared CephFS volume become visible without restarting Apache.
+
+## Continuous integration
+
+The Gitea Actions workflow builds and tests the image on every push. It also
+rebuilds the rolling Arch Linux base every Monday. Push builds publish the
+image to `registry.brunner.ninja/feedc0de/php-apache` with the Git commit SHA.
+Builds of `main` additionally publish `latest` and an
+`<apache-version>-<php-version>` tag. Scheduled and manually dispatched builds
+do not overwrite commit tags; they refresh only the mutable main tags.
+
+The workflow requires these repository secrets:
+
+- `QUAY_USERNAME`: Quay robot-account username with write access to the image.
+- `QUAY_TOKEN`: token for that robot account.
+- `PACKAGE_USERNAME`: Gitea user that publishes packages for `feedc0de`.
+- `PACKAGE_TOKEN`: Gitea token with package write access.
+
+No downstream repository is triggered. PostgreSQL support is part of this
+image, and derivative images such as phpPgAdmin rebuild on their own schedule.
+
+## PHP homepage Helm chart
+
+`helm/php-homepage` deploys this image with a CephFS-backed web root. Existing
+sites should set `persistence.existingClaim`; in that mode the chart references
+the PVC but deliberately does not render or own it. This keeps site content
+independent of the Helm release and safe from `helm uninstall`.
+
+The chart can create a new RWX PVC when `existingClaim` is empty. Such PVCs
+carry Helm's `keep` resource policy by default as an additional safeguard for
+website content.
+
+Each successful `main` or scheduled image build also publishes a new chart to
+the `feedc0de` Gitea Helm registry. Its `appVersion` is the unique image tag
+built by that same workflow run. Site values do not override the image, so
+updating the Helm repository and upgrading a release selects the image from the
+new chart:
+
+```sh
+helm repo add brunner https://code.brunner.ninja/api/packages/feedc0de/helm
+helm repo update brunner
+helm upgrade --install example-site brunner/php-homepage -f values.yaml
+```

+# PHP homepage chart
+
+This chart runs the unified `php-apache` image with a web root mounted at
+`/srv/http`. It is intended for sites whose source and mutable application data
+live on CephFS so the same files are available to the runtime pod and the
+browser-based development container.
+
+Published chart packages set `appVersion` to the unique php-apache image tag
+created in the same CI run. `image.tag` is empty by default and therefore uses
+that `appVersion`. Keep site-specific values free of image overrides so a chart
+upgrade also upgrades the runtime image.
+
+Add and refresh the Gitea chart repository with:
+
+```sh
+helm repo add brunner https://code.brunner.ninja/api/packages/feedc0de/helm
+helm repo update brunner
+```
+
+## Existing sites
+
+Set the existing RWX claim in the site's values file:
+
+```yaml
+fullnameOverride: example-site
+
+persistence:
+  existingClaim: example-site
+```
+
+When `existingClaim` is set, the chart emits no PersistentVolumeClaim. Helm
+therefore neither owns nor deletes the claim. Deleting the release removes the
+workload but leaves all website files intact.
+
+The first installation can adopt a Deployment, Service, and Ingress previously
+created by `kubectl apply`:
+
+```sh
+helm upgrade --install example-site brunner/php-homepage \
+  --namespace default \
+  --values /path/to/example-site/values.yaml \
+  --take-ownership \
+  --wait
+```
+
+Review `helm template` or a server-side dry-run before adoption. The release
+name and `fullnameOverride` must match the existing resource names. The chart's
+selector remains the legacy `app: <resource-name>` selector so Kubernetes does
+not reject the Deployment because its selector is immutable.
+
+## New sites
+
+With `persistence.existingClaim` empty, the chart creates an RWX PVC using
+`rook-cephfs`. The PVC has `helm.sh/resource-policy: keep` by default, so an
+uninstall does not discard site content. Set `persistence.retain: false` only
+when deleting the release should also delete its dynamically created claim.
+
+Ingress, TLS, probes, scheduling, storage size, and the image tag are all
+configurable through `values.yaml`. TCP probes are used by default because
+individual websites may redirect `/`, require authentication, or select their
+own HTTP status behavior.
