Exec processes do not automatically inherit AppArmor
profiles from the container.
This patch sets the AppArmor profile for the exec
process.
Before this change:
apparmor_parser -q -r <<EOF
#include <tunables/global>
profile deny-write flags=(attach_disconnected) {
#include <abstractions/base>
file,
network,
deny /tmp/** w,
capability,
}
EOF
docker run -dit --security-opt "apparmor=deny-write" --name aa busybox
docker exec aa sh -c 'mkdir /tmp/test'
(no error)
With this change applied:
docker exec aa sh -c 'mkdir /tmp/test'
mkdir: can't create directory '/tmp/test': Permission denied
