The FAQs should be pulled out from the documentation as they are specific to a version of Talos and more of a marketing message. This adds a dedicated page for the FAQs. Signed-off-by: Andrew Rynhard <andrew@andrewrynhard.com>

<h1>What is Talos?</h1>
|
|
<div>
|
|
<p>
|
|
Talos is a made up of a few pieces. The first piece is an
|
|
API-driven, purpose-built OS, based on Linux. Its entire purpose is
|
|
to host a Kubernetes cluster, so it is not a general purpose OS. The
|
|
OS consists of the Linux kernel, a simplified init system, and a
|
|
series of components that run in containers on the system, managing
|
|
things like connections between the nodes, routes and networking,
|
|
and serving APIs. It doesn't have SSH or a package manager. Instead,
|
|
all of the management of Talos happens over an API.
|
|
</p>
|
|
|
|
<p>
|
|
The second piece of Talos is <tt>osctl</tt>: the command-line
|
|
interface to manage your Talos-based Kubernetes cluster. It lets you
|
|
do all of the basic system administration on your cluster. You can
|
|
view process lists, download log files, and so forth. It's designed
|
|
specifically to help you debug problems on the cluster during
|
|
development and testing.

<h1>How is Talos different than CoreOS/RancherOS/Linuxkit?</h1>
|
|
<div>
|
|
<p>
|
|
Talos shares a lot of attributes with these systems, but there are
|
|
some important differences. Talos integrates tightly with
|
|
Kubernetes, and is not meant to be a general-purpose operating
|
|
system. The most important difference is that Talos is fully
|
|
controlled by an API via a gRPC interface, instead of an ordinary
|
|
shell. We don't ship SSH, and there is no console access. Removing
|
|
components such as these has allowed us to dramatically reduce the
|
|
footprint of Talos, and in turn, improve a number of other areas
|
|
like security, predictability, reliability, and consistency across
|
|
platforms. It's a big change from how operating systems have been
|
|
managed in the past, but we believe that API-driven OSes are the
|
|
future.

<h1>Why no shell or SSH?</h1>

Since Talos is fully API-driven, all maintenance and debugging
|
|
operations should be possible via the OS API. We would like for
|
|
Talos users to start thinking about what a "machine" is in the
|
|
context of a Kubernetes cluster. That is, that a Kubernetes
|
|
<i>cluster</i> can be thought of as one massive machine, and the
|
|
<i>nodes</i> are merely additional, undifferentiated resources. We
|
|
don't want humans to focus on the <i>nodes</i>, but rather on the
|
|
<i>machine</i> that is the Kubernetes cluster. Should an issue arise
|
|
at the node level, <tt>osctl</tt> should provide the necessary
|
|
tooling to assist in the identification, debugging, and remedation
|
|
of the issue. However, the API is based on the Principle of Least
|
|
Privilege, and exposes only a limited set of methods. We envision
|
|
Talos being a great place for the application of
|
|

in order to provide a self-healing platform.

<h1>Why the name "Talos"?</h1>
|
|
<div>
|
|
<p>
|
|
Talos was an automaton created by the Greek God of the forge to
|
|
protect the island of Crete. He would patrol the coast and enforce
|
|
laws throughout the land. We felt it was a fitting name for a
|
|
security focused operating system designed to run Kubernetes.
