Master-Slave PowerDNS Configuration and Domain Migration from BIND Using API and AXFR
One of my latest projects was a fully dockerized name server infrastructure based on PowerDNS: one master and two slaves — one in the same subnet and the second running in a cloud on a basic virtual machine. Why PowerDNS? Because I needed an API, a proper admin-friendly web interface, user management, and LDAP integration. PowerDNS fully matched my requirements. Why Docker? Because I wanted some level of automation and IaC — Docker fits nicely in the middle, where you have several configs and docker-compose files fully describing the container configuration.
