| I propose to create a Docker ISC Kea Image using base Docker Alpine Linux images, with S6 init system. <fs x-small>(ISC Kea is a modern replacement for their DHCP.)</fs> | Since mid 2023 I have been running a Docker ISC Kea Image using base Docker Alpine Linux images, with S6 init system. <fs x-small>(ISC Kea is a modern replacement for their DHCP.)</fs> The main DHCP server runs on my main server and I have an automatic fall over back up on my separate Linux router. I basically followed the Kea template [[https://kea.readthedocs.io/en/latest/arm/config-templates.html#template-home-network-of-a-power-user|Home Network of a Power User]]. I was never quite sure I had the automatic fall over back-up working. On 2023-01-02 I modified a configuration file on the primary server with a syntax error. Today, 8 days later I notice millions of lines of errors on my log files. Sure enough the backup had simply been working. I fixed up the simple syntax error and the primary server took back over. Everything basically worked as expected. |

| ISC also has a project for a simple GUI interface primarily for Kea and basic for Bind9. There is apparently no Alpine package yet for Stork. | ISC also has a project for a simple GUI interface primarily for Kea and basic for Bind9. There is apparently no Alpine package yet for Stork. |
