supervisor: DNS problems [solved by disabling apparmor]

Good morning and good job. I have installed hassio with docker on Ubuntu. All work ok except the dns resolution of “homeassistant” container.

I tried to reinstall all the containers but I did not solve them

After some days digging in internet and looking for a solution in the sources… i have found the problem. The hassio_supervisor container does not start socat for forward dns (but why you need a dns forwarder to docker dns instead use docker dns directly when launching homeassistant container?)

Running socat command manually or change homeassistant configuration in order to use directly 127.0.0.11 instead hassio_supervisior for dns resolution solve the problem

here some logs and info
