Problem I was trying to run a Docker container called Syslog-ng, and had to add quite a few parameters in order to map the volumes and ports that I needed.

How to install IIS (Internet Information Services) on Windows 10?

It’s the roaring twenties again, cloud is the hot stuff, and nobody needs a server anymore. Right? Nope! I’ve been involved in more on-prem or hybrid projects in the last 12 months than in the last 3-4 years combined. There are plenty of industries and valid uses for still setting up on-prem servers. And quite often, that includes setting up IIS (Internet Information Services) on said machines. And of course,…Continue reading How to install IIS (Internet Information Services) on Windows 10?
