|Earlier today I read an article on the decline of proper sysadmins in the age of containers. I thought I was doing a decent job of being a sysadmin+developer at the place I work but looking at the problems containers can cause I couldn't help wonder how one should go about becoming a decent sysadmin.|
Main scenario is the one where you as an individual might on your own (or with a couple of friends) start some tiny sass product, or build an open source product that you want to keep secure.
At the most basic level, when firing up a new server I follow the how to harden your server guides and install fail2ban, disable root login, enable ssh only login etc.
Things I don't fully understand, user permissions or rather, how to use permissions to ensure good security. I'm also unsure about logging. I'm essentially clueless about where to look to understand what goes into being a good sysadmin.
Any advice would be awesome. Thanks.
