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
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:
grep 'Generated \(Username\|Password\)' /var/log/nifi/nifi-app.log
Set fixed single-user credentials as the service account:
doas -u nifi nifi set-single-user-credentials '<username>' '<password>'
rc-service nifi restart
