opera-dns-ui

A self contained docker image with php-fpm & caddy for Opera's PowerDNS Admin UI

This image is intended to be used behind some form of reverse proxy responsible for Authentication. The proxy should set an X-Auth-User header with the authenticated username for the application. (the application's support for PHP authentication has been enabled, LDAP disabled).

An initial user is created during database initialisation by the application, specified by the ADMIN_USER environment variable.

Environment variables:

Variable Name	Default	Description
ADMIN_USER	admin	Initial admin username for DNS UI
MAIL_SERVER	smtp	SMTP mail server hostname for outgoing mail
POSTGRES_HOST	postgres	Postgresql database host
POSTGRES_PORT	5432	Postgresql database port
POSTGRES_DB	dnsui	Database name
POSTGRES_USER	dnsui	Database user/role
POSTGRES_PASSWORD	dnsui	Database password
PDNS_API_HOST	172.17.0.1	PowerDNS API host
PDNS_API_PORT	8081	PowerDNS API Port
PDNS_API_KEY	change	PowerDNS API key

Example docker invocation:

docker run -d                                      \
       -e MAIL_SERVER=smtp.example.com             \
