Installing a SlapOS Node under SONiC

This tutorial will guide you through the process of installing a SlapOS node on a computer which has SONiC installed. A regular node (referred to as COMP-1,2,3) is used by the SlapOS Master to install software on the node and then provide instances of this software within computer partitions. For details please refer to the SlapOS introduction.

For this tutorial you will require a SlapOS Master and (first) user account, which can either be your own installed SlapOS Master or a commercial service like Vifib in order to register your node and another computer on which to install the SlapOS node. The tutorial will use an arbitrary GNU/Linux server from a cloud provider (Debian10, available for example from OVHor Online.net) with wget installed.

Note, that there is one node referred to as COMP-0 throughout the documentation, which provides services to SlapOS Master (COMP-ROOT) besides regular nodes like the one we are going to install here (called COMP-1,2,3...).

This tutorial will show how to create a SlapOS node under SONiC using a commercial service like Vifib.

Request a FreeFib token

First of all, you need to request a FreeFib token, in order to isntall your SlapOS node. You can do it byt following these tutorials: creating a user account and then request a FreeFib token.

Installing Re6st under SONiC

sudo su
# yum install wget

(...)

# # ViFiB commercial service:
# wget https://deploy.erp5.net/gnet/re6st && bash re6st

ssh into the terminal of your server, switch to root and verfiy wget is available. Then install re6st as shown above.

The setup should finish without errors:

Verify Files Created

sudo su

# ls /etc/re6stnet/

ca.crt cert.cert cert.key re6stnet.conf README

Verify that the configuration files were created. You can also call:

echo "default" >> /etc/re6stnet/re6stnet.conf

and make sure the service is started by calling:

/etc/init.d/re6stnet restart

Verify Re6st is Running

sudo su

# service re6stnet status

You can use the above command to see whether Re6st is working. The output should be similar to:
