Running PowerDNS-Admin

There are several ways to run PowerDNS-Admin. Following is a simple way to start PowerDNS-Admin with docker in development environment which has PowerDNS-Admin, PowerDNS server and MySQL Back-End Database.

Step 1: Changing configuration

The configuration file for development environment is located at configs/development.py, you can override some configs by editing the .env file.

Step 2: Build docker images

$ docker-compose build

Step 3: Start docker containers

$ docker-compose up

You can now access PowerDNS-Admin at url http://localhost:9191

NOTE: For other methods to run PowerDNS-Admin, please take look at WIKI pages.

Running tests

NOTE: Tests will create __pycache__ folders which will be owned by root, which might be issue during rebuild

thus (e.g. invalid tar headers message) when such situation occurs, you need to remove those folders as root

1. Build images

  docker-compose -f docker-compose-test.yml build

2. Run tests

  docker-compose -f docker-compose-test.yml up

3. Rerun tests

  docker-compose -f docker-compose-test.yml down

To teardown previous environment

  docker-compose -f docker-compose-test.yml up

To run tests again

API Usage

1. run docker image docker-compose up, go to UI http://localhost:9191, at http://localhost:9191/swagger is swagger API specification
2. click to register user, type e.g. user: admin and password: admin
3. login to UI in settings enable allow domain creation for users,
   now you can create and manage domains with admin account and also ordinary users
4. Encode your user and password to base64, in our example we have user admin and password admin so in linux cmd line we type:

someuser@somehost:~$echo -n 'admin:admin'|base64
YWRtaW46YWRtaW4=

we use generated output in basic authentication, we authenticate as user, with basic authentication, we can create/delete/get zone and create/delete/get/update apikeys

creating domain:

curl -L -vvv -H 'Content-Type: application/json' -H 'Authorization: Basic YWRtaW46YWRtaW4=' -X POST http://localhost:9191/api/v1/pdnsadmin/zones --data '{"name": "yourdomain.com.", "kind": "NATIVE", "nameservers": ["ns1.mydomain.com."]}'

creating apikey which has Administrator role, apikey can have also User role, when creating such apikey you have to specify also domain for which apikey is valid:

curl -L -vvv -H 'Content-Type: application/json' -H 'Authorization: Basic YWRtaW46YWRtaW4=' -X POST http://localhost:9191/api/v1/pdnsadmin/apikeys --data '{"description": "masterkey","domains":[], "role": "Administrator"}'

call above will return response like this:

[{"description": "samekey", "domains": [], "role": {"name": "Administrator", "id": 1}, "id": 2, "plain_key": "aGCthP3KLAeyjZI"}]

we take plain_key and base64 encode it, this is the only time we can get API key in plain text and save it somewhere:

someuser@somehost:~$echo -n 'aGCthP3KLAeyjZI'|base64
YUdDdGhQM0tMQWV5alpJ

We can use apikey for all calls specified in our API specification (it tries to follow powerdns API 1:1, only tsigkeys endpoints are not yet implemented), don't forget to specify Content-Type!

getting powerdns configuration:

curl -L -vvv -H 'Content-Type: application/json' -H 'X-API-KEY: YUdDdGhQM0tMQWV5alpJ' -X GET http://localhost:9191/api/v1/servers/localhost/config

creating and updating records:

curl -X PATCH -H 'Content-Type: application/json' --data '{"rrsets": [{"name": "test1.yourdomain.com.","type": "A","ttl": 86400,"changetype": "REPLACE","records": [ {"content": "192.0.2.5", "disabled": false} ]},{"name": "test2.yourdomain.com.","type": "AAAA","ttl": 86400,"changetype": "REPLACE","records": [ {"content": "2001:db8::6", "disabled": false} ]}]}' -H 'X-API-Key: YUdDdGhQM0tMQWV5alpJ' http://127.0.0.1:9191/api/v1/servers/localhost/zones/yourdomain.com.

getting domain:

curl -L -vvv -H 'Content-Type: application/json' -H 'X-API-KEY: YUdDdGhQM0tMQWV5alpJ' -X GET http://localhost:9191/api/v1/servers/localhost/zones/yourdomain.com

list zone records:

curl -H 'Content-Type: application/json' -H 'X-API-Key: YUdDdGhQM0tMQWV5alpJ' http://localhost:9191/api/v1/servers/localhost/zones/yourdomain.com

add new record:

curl -H 'Content-Type: application/json' -X PATCH --data '{"rrsets": [ {"name": "test.yourdomain.com.", "type": "A", "ttl": 86400, "changetype": "REPLACE", "records": [ {"content": "192.0.5.4", "disabled": false } ] } ] }' -H 'X-API-Key: YUdDdGhQM0tMQWV5alpJ' http://localhost:9191/api/v1/servers/localhost/zones/yourdomain.com | jq .

update record:

curl -H 'Content-Type: application/json' -X PATCH --data '{"rrsets": [ {"name": "test.yourdomain.com.", "type": "A", "ttl": 86400, "changetype": "REPLACE", "records": [ {"content": "192.0.2.5", "disabled": false, "name": "test.yourdomain.com.", "ttl": 86400, "type": "A"}]}]}' -H 'X-API-Key: YUdDdGhQM0tMQWV5alpJ' http://localhost:9191/api/v1/servers/localhost/zones/yourdomain.com | jq .

delete record:

curl -H 'Content-Type: application/json' -X PATCH --data '{"rrsets": [ {"name": "test.yourdomain.com.", "type": "A", "ttl": 86400, "changetype": "DELETE"}]}' -H 'X-API-Key: YUdDdGhQM0tMQWV5alpJ' http://localhost:9191/api/v1/servers/localhost/zones/yourdomain.com | jq

OAuth Authentication

Microsoft Azure

To link to Azure for authentication, you need to register PowerDNS-Admin in Azure. This requires your PowerDNS-Admin web interface to use an HTTPS URL.

• Under the Azure Active Directory, select App Registrations, and create a new one. Give it any name you want, and the Redirect URI shoule be type 'Web' and of the format https://powerdnsadmin/azure/authorized (replace the host name approriately).
• Select the newly-created registration
• On the Overview page, the Application ID is your new Client ID to use with PowerDNS-Admin
• On the Overview page, make a note of your Directory/Tenant ID - you need it for the API URLs later
• Ensure Access Tokens are enabled in the Authentication section
• Under Certificates and Secrets, create a new Client Secret. Note this secret as it is the new Client Secret to use with PowerDNS-Admin
• Under API Permissions, you need to add permissions. Add permissions for Graph API, Delegated. Add email, openid, profile, User.Read and possibly User.Read.All. You then need to grant admin approval for your organisation.

Now you can enable the OAuth in PowerDNS-Admin.

• For the Scope, use 'User.Read openid mail profile'
• Replace the [tenantID] in the default URLs for authorize and token with your Tenant ID.
• Restart PowerDNS-Admin

This should allow you to log in using OAuth.
