I've learnt docker several years ago. Yeah,it's a nice tool. I can say for sure that after docker you will learn how to use the jails for FreeBSD. This has been my recent goal. Anyway,soon I will try to follow your docker tutorial and I will keep you updated because I know that you will learn something more from what will happen. (and me too).

Thanks for your feedback @Marietto2008 . Will be happy to learn more about networks, blue team defensive security (not so much offensive because too many people already do that and it is not my "taste". I prefer defensive security. Learning how to protect a system rather than "attack" it. I know one cannot exists without the other side of the coin, but again, my focus is on defensive cyber security. jails system might be something to consider will have a look when I get a chance to.

2 years ago I started learning FreeBSD and it was "love" at first sight. FreeBSD has some evident advantages over Linux.
