You just created a CentOS container (release=7, arch=amd64, variant=default)

To enable sshd, run: yum install openssh-server

For security reason, container images ship without user accounts
and without a root password.

Use lxc-attach or chroot directly into the rootfs to set a root password
or create user accounts.
