# SELinux policy for LXC for RHEL/CentOS/Oracle 6.5.
|
|
# It attempts to restrict the container to the same amount of access
|
|
# as an unprivileged user. To build and insert this policy module:
|
|
#
|
|
# make -f /usr/share/selinux/devel/Makefile lxc.pp
|
|
# semodule -i lxc.pp
|
|
#
|
|
# In your container's lxc config:
|
|
# lxc.selinux.context = system_u:system_r:lxc_t:s0:c62,c86,c150,c228
|
|
#
|
|
# Ensure your container's rootfs files are labeled:
|
|
# chcon -R system_u:object_r:lxc_file_t:s0:c62,c86,c150,c228 /path/to/rootfs
|
|
#
|
|
# To keep containers separated from each other, you should vary the MCS
|
|
# portion of the contexts above to be a unique set of values for each
|
|
# container, each MCS compartment can be a number from 0-1023.
