container-tools: Host Setup
===========================
1. Debian Packages
-------------------
apt install net-tools bridge-utils ifenslave vlan
2. Boot Parameters
------------------
2.1 CGroup Memory Controller
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In order to enable the memory controller the following boot parameter needs to be used:
cgroup_enable=memory
2.2 CGroup Swap Controller
~~~~~~~~~~~~~~~~~~~~~~~~~~
In order to enable the swap controller the following boot parameter needs to be used:
swapaccount=1
3. Networking
~~~~~~~~~~~~~
3.1 Enable IPv4 Forwarding
~~~~~~~~~~~~~~~~~~~~~~~~~~
apt install procps
echo "net.ipv4.ip_forward = 1" > /etc/sysctl.d/ip_foward.conf
sysctl -p

4. Enabling container-shell
---------------------------
Managing containers requires root privileges. In order to allow unprivileged
users to manage containers without granting them privileges or accounts,
the container-shell can be used together with sudo and a container user.
sudo adduser --gecos "container-tools,,," \
--home /var/lib/machines/container-tools \
--shell /usr/bin/container-shell \
--no-create-home container
