Running SlapOS

Running SlapOS Slave Node on your Computer

The goal of this tutorial is to walk you through the first run of your freshly installed SlapOS Slave node.

If you didn't install a SlapOS node, please do so by following the tutorial on installing SlapOS.

As a general convention, commands prepended with $ might be run as ordinary user whereas commands prepended by # require superuser privileges.

Agenda

  • Get Token from SlapOS Master
  • Register your server
  • Network Configuration
  • Run

This tutorial will first explain how to register the server to Slapos Master community Cloud, then how to run a SlapOS Node, or rather let it run itself.

Get token from SlapOS Master

Before proceeding further, we need to register your server to https://slapos.org or https://slapos.vifib.com community Cloud. By doing so, we will obtain X509 certificate and key which are later needed for the configuration process.

Step 1: Register and obtain a Computer security Token

Go to imtweb.tl.teralab-datascience.fr, register if not already done, go to My Account and click on Generate a Computer Secuity Token:

Step 1.5: Save the New Token

  • As soon as you click on the button a new token will be generated. Save this token for future use on this tutorial.

IPv6

This section is intended for those who do not have native IPv6 or not reliable IPv6. We will explain how to use an IPv6 tunnel.

Luckily, IPv6 is increasingly available worldwide thanks to companies such as Free or Biglobe. If your Internet service provider or hosting provider does not provide native IPv6, simply complain and remind him that 80% of worldwide IPv6 traffic in 2011 comes from France thanks to innovative companies such as Free and OVH. Strongly complain that due to their conservatism, they are putting the whole country lagging behind and prevent innovation to happen in local startup companies. If this is not sufficient, consider complaining to regulation authorities. No technical reason justifies the absence of IPv6 nowadays.

If your network does not provide global, routable IPv6 adresses, you will need to setup an OpenVPN. In order to you have IPv6 everywhere is quite easy with Re6st Server or OpenVPN server provided by slapos.org:

Selecting the IPv6 interface

During your configuration file you are going to select the appropriate IPv6 interface you configured (consider eth0 as your internet interface ):

  • For re6st uses include "ipv6_interface = lo" above "interface_name = eth0"
  • If your eth0 has IPv6 include only "interface_name = eth0"
  • For tapVPN uses include "ipv6_interface = tapVPN" above "interface_name = eth0"

Step 2: Run slapos node register

Run slapos command below, to create the configuration  files, when asked please input the Token Saved on Step above.

 This command will generate several files at:

open="true">

Everything
is
set.
It
is
now
time
to
prepare
your
computer
for
slapos.

First Run

Now run slapos for the the first time for finish configuration:

# slapos node format --alter_user=True --now

Next

open="true">

It
is
now
time
to
discuss
what
to
do
next
with
SlapOS
now
that
we
have
an
idea
of
its
architecture
and
of
the
practical
installation
process.
Experimenting
with
more
machines,
in
different
places
of
the
world,
with
different
CPU
architecture
and
network
is
a
great
source
of
innovation.
You
should
also
have
a
look
at
the
tutorial
which
explains
how
to
install
SlapOS
on
a
USB
key.
It
is
much
faster
and
efficient,
but
does
not
teach
so
well
the
internals
of
SlapOS
as
what
we
just
did.

Where to go next?

  • Contribute documentation
  • IPv6 Support
  • System permissions
  • Follow other SlapOS tutorials

If you wish to contribute, to SlapOS and to this tutorial, here is a list of possible topics. First, this documentation needs peer review and improved explanations. Seconds, the different approachs to setup an IPv6 networks needs to be extended. We need good tutorials to explain how to achieve this in different environments (routable IPv6, non routable, protocol 41 tunnelling, use of tinc or OpenVPN to provide IPv6, etc.). And we need more precisions on system permissions for the different directories of SlapOS. Those are already defined in the USB Key setup (Kiwi configuration file) but more documentation is needed.
