Congratulations! At this point, you have a working installation of Docker
on |CL|. You are ready to start using container images on your system.
Integration with Clear Containers (optional)
Integration with Kata Containers (optional)
********************************************
`Clear Containers`_, is an open source project aiming to increase security
`Kata Containers`_, is an open source project aiming to increase security
of containers by using a hardware-backed virtual machine container runtime,
instead of software namespace containers that are provided by the standard
rather than software namespace containers which are provided by the standard
Docker *runc* runtime.
The Docker package from |CL| will automatically use the *cc-runtime*
required for Clear Containers if it is available on your Clear Linux system.
Clear Linux provides easy integration of the *kata-runtime* with Docker.
More information on installing and using the *kata-runtime* can be found at :ref:`kata`
#. To take advantage of Clear Containers in |CL|, install the
*containers-virt* bundle by running this command:
.. code-block:: bash
sudo swupd bundle-add containers-virt
#. Restart the Docker daemon through systemd manager by running this command:
.. code-block:: bash
sudo systemctl restart docker
#. After restarting, the Docker daemon will seamlessly use Clear Containers
to launch containers. You can see the runtime has changed to
:command:`cc-runtime` by running this command:
.. code-block:: bash
sudo docker info | grep Runtime
#. You should see the following output indicating the *cc-runtime* is the
Default Runtime:
.. code-block:: console
Runtimes: cc-runtime runc
Default Runtime: cc-runtime
Congratulations! At this point, you have successfully replaced the default
container runtime with Clear Containers.
