Ubuntu 16.04 LXD : install wireshark within CentOS based containers

I could install wireshark within Ubuntu-based LXD container by default configuration, but could not install wireshark on CentOS-based containers until I set “security.privileged” to true.

Here is what I did.

start a Cent7 container
$ lxc launch 8c7eed37f93c cent7-01

install wireshark
failed to install wireshark.
$ lxc exec cent7-01 bash
[root@cent7-01 ~]# yum install wireshark –y

stop the conainer and set security.privileged to true.
$ lxc stop cent7-01

$ lxc config set cent7-01 security.privileged true

$ lxc config show cent7-01 | grep security
 security.privileged: "true"

start the container and install wireshark
$ lxc start cent7-01

You can also set “security.privileged true” to a profile as below.
