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.

Some time ago I faced a serious challenge: migrating a large number of similar websites from DirectAdmin to ISPConfig with maximum automation. The hosting platform was changed, and doing everything manually simply wasn’t an option. To solve this, I wrote a better CLI wrapper for ISPConfig that focuses on usability while reusing the default API functions underneath: ispconfig-cli

When I was try start 150+ docker containers with docker-compose I found strange problem: "Could not generate persistent MAC address"

Many mail clients show wrong email receiving date-time, because file creation time is wrong after migration or restore. Here short review how to fix it for Dovecote on ISPConfig.

Times to time I need to create script with user friendly interface, for this usage with ARG0, ARG1... bad form. Here example how to use normal argument's like "script.sh -h"
