The docker install guides end with a call to `docker run`. However, they all specify `-ti` which is causing our CI to fail. Remove the `-ti` so that the command works both under the CI and as expected for the user. Fixes #175. Signed-off-by: James O. D. Hunt <james.o.hunt@intel.com>

Install Docker for Kata Containers on Ubuntu
Note:
This guide assumes you have already installed the Kata Containers packages.
If you do not want to copy or type all these instructions by hand, you can use the
kata-managerscript to install the packaged system including your chosen container manager. Alternatively, you can generate a runnable shell script from individual documents using thekata-doc-to-scriptscript.

Install the latest version of Docker with the following commands:
Note: This step is only required if Docker is not installed on the system.
$ sudo -E apt-get -y install apt-transport-https ca-certificates software-properties-common $ curl -sL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - $ arch=$(dpkg --print-architecture) $ sudo -E add-apt-repository "deb [arch=${arch}] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" $ sudo -E apt-get update $ sudo -E apt-get -y install docker-ceFor more information on installing Docker please refer to the Docker Guide.
-
Configure Docker to use Kata Containers by default with the following commands:
$ sudo mkdir -p /etc/systemd/system/docker.service.d/ $ cat <<EOF | sudo tee /etc/systemd/system/docker.service.d/kata-containers.conf [Service] ExecStart= ExecStart=/usr/bin/dockerd -D --add-runtime kata-runtime=/usr/bin/kata-runtime --default-runtime=kata-runtime EOF -
Restart the Docker systemd service with the following commands:
$ sudo systemctl daemon-reload $ sudo systemctl restart docker -

You are now ready to run Kata Containers:
$ sudo docker run busybox uname -aThe previous command shows details of the kernel version running inside the container, which is different to the host kernel version.
