Jails is just a process isolation technology. Docker is a ready product (based on the Linux equivalents of jails, mount_unionfs etc). When iocage or pot are mature enough (hopefully), we well be able to compare docker vs iocage, and this would be a fair comparison. > granted it's not as easy as writing a yaml file and watching a > poorly understood swarm of thousands of containers spring to life and > provide a load-balanced service, but it isn't hard especially with iocage > templates. Glad you understand that. Many people touting jail don't realize it. >=20 > Personally I always run services in single service jails and have > done for a lot longer than docker has existed.=20 It could be great if FreeBSD provided an infrastructure for this. If for example, for every service XXX there existed a XXX_enable=3D"YES" XXX_jailed=3D"jail1" That would be a huge advantage. >=20 > I have systems which have been steadily upgraded from 8.<mumble> to > 12.1 with only a single (easily corrected) upgrade glitch (the drm_kmod > issue) and not a single byte of data lost.

I fully agree with you here, especially taking into account that Linuxes lack the notion of the base system and boot environments. --=20 Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/ --hoZxPH4CaxYzWscb Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJfG9MtAAoJEA2k8lmbXsY0WRoH/2gd6ybd2t6SnVWTkbeGKWy2 UlcwbupRxEMbK5zX4hrB+dkqEGQ/Ge3dhQmRnZDLdIJ+ZgspsNWr1lIDjkbpmSJa sa/FYWNmdarh4DS7NJfr4TFHE9vwyw0qmb/wjmDIwyaVHefVHGWBPCH0Z6hGsyU9 iq2lW9JoL9pLEr8PC/RzCHcINhYeYlISD1UDD5+TuGc3fHALDpFBZ1fXEUxAB1zU 0XSadoTNyrooFr58dZg3T9iy7xR9pVf2MvZrUP2usu7Ik45/qcrxLi4+b/AGe0s5 ofztRbBYk/USQ3r6pOv6FkYAKrucCCqCIHf/Cwxj0dhenNXF9hH2+ia6Q3Rm9dQ= =Q510 -----END PGP SIGNATURE----- --hoZxPH4CaxYzWscb--
