# Apache NiFi Alpine Package

Repackages Apache NiFi 2.12.0 Standard for Alpine. The package requires Java
21 and retains NiFi 2's secure default: HTTPS listens on `127.0.0.1:8443` and
uses generated single-user credentials.

## Install

```sh
apk add nifi nifi-openrc
rc-update add nifi default
rc-service nifi start
```

Open `https://127.0.0.1:8443/nifi` and retrieve the generated credentials:

```sh
grep 'Generated \(Username\|Password\)' /var/log/nifi/nifi-app.log
```

Set fixed single-user credentials as the service account:

```sh
doas -u nifi nifi set-single-user-credentials '<username>' '<password>'
rc-service nifi restart
```

## Runtime Layout

```text
/usr/bin/nifi              Administration command wrapper
/usr/lib/nifi              NiFi binaries and bundled NARs
/etc/nifi                  Mutable NiFi configuration and authorization state
/var/lib/nifi              Repositories, state, extensions, and work files

TLS, or select LDAP, OIDC, or another supported authentication provider.
