SOLVED Jails future

[f4242]

Hello,

I'm a new user to FreeNAS. I avoided Corral after testing it and found it was not mature enough and started with 9.10.

Since I knew that jails was removed in Corral, I avoided the use of jails to make the upgrading to Corral easiest.

Now that Corral is abandoned and FreeNAS 11 is coming soon with jails support, I wonder if I should still avoid the use of jails. VM is great, but not always the best tool. I don't care about plugins using jails as backend, just basic jail support. Do you still plan to remove them in a future release?



Thanks.

Definitely no plans to remove jails and they have always been in the 9.x series. They've also received some much needed love for the upcoming 11 release. 11-RC1 is expected next week so that would be a great time to start setting up your jails!

Could you provide a link with said information, please.

The technical details won't hit the Guide until 11.0-U1 (https://bugs.freenas.org/issues/21209), but the new templates are available at
https://github.com/freenas/iocage-ix-plugins/.

In a nutshell, jails in 11 are being rebased to iocage instead of warden and those templates are now JSON files.

This is some really good news. I couldn't care less about docker... I have no interest in running stuff inside 3 onion layers of abstraction/virtualization and the performance hit that inherits. If I wanted to run my stuff in Linux, I wouldn't be running FreeNAS in the first place.

Jails work beautifully for me, and I hear about too many performance complaints about docker when trying to do the same stuff I'm doing. Since the stuff inside my jail is more CPU-intensive than the stuff outside the jail (FreeNAS itself), performance is key.

I am also really happy to hear this - I love Jails and the general "FreeBSD" way of doing things -- plus, I like putting all my softwares in the same FreeBSD jail so I don't have to re-configure stuff for each new pkg install... LONG LIVE JAILS on FreeNAS!! Feel free to re-visit the Docker setup in Bhyve, as it may be useful, but please also keep jails!
