# PowerDNS Docker Images
|
||||
|
||||
This repository contains two Docker images - pdns-mysql and pdns-admin. Image **pdns-mysql** contains completely configurable [PowerDNS 4.x server](https://www.powerdns.com/) with mysql backend (without mysql server). Image **pdns-admin** contains [PowerDNS Admin](https://github.com/ngoduykhanh/PowerDNS-Admin) web app, written in Flask, for managing PowerDNS servers. Pdns-admin is also completely configurable, running under uWSGI with nginx.
|
||||
This repository contains four Docker images - pdns-mysql, pdns-admin-static, pdns-admin-uwsgi and deprecated pdns-admin. Image **pdns-mysql** contains completely configurable [PowerDNS 4.x server](https://www.powerdns.com/) with mysql backend (without mysql server). Images **pdns-admin-static** and **pdns-admin-uwsgi** contains fronted (nginx) and backend (uWSGI) for [PowerDNS Admin](https://git.omicroninteractive.com/0x97/powerdns-admin) web app, written in Flask, for managing PowerDNS servers. Pdns-admin is also completely configurable. Deprecated **pdns-admin** contains PowerDNS Admin in single image where both nginx and uWSGI processes are managed by systemd. This image won't be updated anymore.
|
||||

||||

|
||||
|
||||
Docker image with backend of [PowerDNS Admin](https://git.omicroninteractive.com/0x97/powerdns-admin) web app, written in Flask, for managing PowerDNS servers. This image contains the python part of the app running under uWSGI. It needs external mysql server. Env vars for mysql configuration:
|
||||
```
|
||||
(name=default value)
|
||||
|
||||
PDNS_ADMIN_SQLA_DB_HOST="'mysql'"
|
||||
PDNS_ADMIN_SQLA_DB_PORT="'3306'"
|
||||
PDNS_ADMIN_SQLA_DB_USER="'root'"
|
||||
PDNS_ADMIN_SQLA_DB_PASSWORD="'powerdnsadmin'"
|
||||
PDNS_ADMIN_SQLA_DB_NAME="'powerdnsadmin'"
|
||||
```
|
||||
If linked with official [mariadb](https://hub.docker.com/_/mariadb/) image with alias `mysql`, the connection can be automatically configured, so you don't need to specify any of the above. Also, DB is automatically initialized if tables are missing.
|
||||
|
||||
Similar to the pdns-mysql, pdns-admin is also completely configurable via env vars. Prefix in this case is `PDNS_ADMIN_`, but there is one caveat: as the config file is a python source file, every string value must be quoted, as shown above. Double quotes are consumed by Bash, so the single quotes stay for Python. (Port number in this case is treated as string, because later on it's concatenated with hostname, user, etc in the db uri). Configuration from these env vars will be written to the `/opt/powerdns-admin/config.py` file.
|
||||
|
||||
### Connecting to the PowerDNS server
|
||||
|
||||
For the pdns-admin to make sense, it needs a PowerDNS server to manage. The PowerDNS server needs to have exposed API (example configuration for PowerDNS 4.x):
|
||||
```
|
||||
api=yes
|
||||
api-key=secret
|
||||
webserver=yes
|
||||
```
|
||||
|
||||
And again, PowerDNS connection is configured via env vars (it needs url of the PowerDNS server, api key and a version of PowerDNS server, for example 4.0.1):
|
||||
```
|
||||
(name=default value)
|
||||
|
||||
PDNS_ADMIN_PDNS_STATS_URL="'http://pdns:8081/'"
|
||||
PDNS_ADMIN_PDNS_API_KEY="''"
|
||||
PDNS_ADMIN_PDNS_VERSION="''"
|
||||
```
|
||||
|
||||
If this container is linked with pdns-mysql from this repo with alias `pdns`, it will be configured automatically and none of the env vars from above are needed to be specified.
|
||||
|
||||
### Persistent data
|
||||
|
||||
There is a directory with user uploads which should be persistent: `/opt/powerdns-admin/upload`
|
||||
|
||||
### Example
|
||||
|
||||
When linked with pdns-mysql from this repo and with LDAP auth:
|
||||
```
|
||||
docker run -d --name pdns-admin-uwsgi \
|
||||
--link mariadb:mysql --link pdns-master:pdns \
|
||||
-v pdns-admin-upload:/opt/powerdns-admin/upload \
|
||||
-e PDNS_ADMIN_LDAP_TYPE="'ldap'" \
|
||||
-e PDNS_ADMIN_LDAP_URI="'ldaps://your-ldap-server:636'" \
|
||||
-e PDNS_ADMIN_LDAP_USERNAME="'cn=dnsuser,ou=users,ou=services,dc=example,dc=com'" \
|
||||
-e PDNS_ADMIN_LDAP_PASSWORD="'dnsuser'" \
|
||||
-e PDNS_ADMIN_LDAP_SEARCH_BASE="'ou=System Admins,ou=People,dc=example,dc=com'" \
|
||||
-e PDNS_ADMIN_LDAP_USERNAMEFIELD="'uid'" \
|
||||
-e PDNS_ADMIN_LDAP_FILTER="'(objectClass=inetorgperson)'" \

Fronted image with nginx and static files for [PowerDNS Admin](https://git.omicroninteractive.com/0x97/powerdns-admin). Exposes port 80 for connections, expects uWSGI backend image under `pdns-admin-uwsgi` alias.
|
||||
|
||||
