+# Apache NiFi Registry Alpine Package
+
+Repackages Apache NiFi Registry 2.12.0 for Alpine. The package requires Java
+21 and preserves the upstream default: an unsecured HTTP service listening on
+port 18080. Configure TLS and authentication before exposing it to an
+untrusted network.
+
+## Install
+
+```sh
+apk add nifi-registry nifi-registry-openrc
+rc-update add nifi-registry default
+rc-service nifi-registry start
+```
+
+Open `http://127.0.0.1:18080/nifi-registry/`.
+
+## Runtime Layout
+
+```text
+/usr/bin/nifi-registry       Administration command wrapper
+/usr/lib/nifi-registry       NiFi Registry binaries and bundled extensions
+/etc/nifi-registry           Mutable configuration and authorization state
+/var/lib/nifi-registry       Database, flow, extension, and work files
+/var/log/nifi-registry       Application logs
+/etc/conf.d/nifi-registry    OpenRC account defaults
+/etc/init.d/nifi-registry    OpenRC service
+```
+
+Edit `/etc/nifi-registry/nifi-registry.properties` to configure HTTPS, TLS,
+authentication, and the listening address. Registry has been deprecated
+upstream in favor of NiFi's Git-based Flow Registry clients, but remains
+available through the NiFi 2.x series.
+
+## Package Commands
+
+```sh

+ALPINE_PACKAGE=nifi-registry mise run apk:build
+ALPINE_PACKAGE=nifi-registry SKIP_BUILD=1 mise run apk:test-install
