[raykai]

is it safe to tern off apparmor ?

If apparmor needs to be off why doesn't plesk tern it off when we do a fresh install of plesk on Ubuntu ?

We can't switch off any security protections/toos/solutions initially specified by the user for some reasons.

Just disable it as it is described in KB article and forget it

ok, i have 2 questions i see on : https://support.plesk.com/hc/en-us/articles/213909965

That if im using Docker on Ubuntu 16.04 that i should keep AppArmor...

i have websites running on plesk (not on docker) and im also using docker for other things... so what should i do, if i keep AppArmor i get alot of log errors but if i remove it seams to me docker will stop working.

An other note that i don't get is "Do not purge apparmor if you think you might want to re-enable AppArmor at a later date." so what command should some one skip in the list if they mite need AppArmor back at some point ?
i dont see a purge line in the codes on that page, so what do they mean by that?

Thx for your time.

@IgorG bump

Have you seen last update of this article?

Note : AppArmor is required for Docker on Ubuntu 14.04 and 16.04, so do not disable it on these operating systems. Plesk supports AppArmor on them.
