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

Sep 27 10:11:37 test-kvm systemd\[1\]: Started re6stnet.service - Resilient, Scalable, IPv6 Network application.

After this step, Re6st is installed and the machine is accessible over IPv6.

The single line installer script you will be executing on your server will ask your for a valid X509 security token to identify your node with a SlapOS Master and enable it to manage the node within a network.
Such a token is called a Compute Node Token, and this section shows how to generate one.

Log in to the Rapid.Space Panel.

1. From the homepage, click on the Projects link in the side to go to your list of accessible projects.
2. Click on the project in which you wish to register the Compute Node.
3. Click on Add Compute Node Token.

Your Compute Node Token is now generated and should be displayed on the screen: copy it for later. The other lines of information above should not be needed.

IMPORTANT: This token can only be used once. If the installation of SlapOS on your server fails for whatever reason and you need to retry, you will need to request a new token beforehand.

Now that your Compute Node Token is ready, SlapOS can be installed on your server via our single-line installer.

Log into your server via your method of choice.

IMPORTANT: You will need to be logged in to the root user.

Run the command as shown above. 

After a few moments during the installation, you will be prompted to answer a set of questions:

• As you are connecting to the SlapOS Master, you can skip the first two questions.

• Next, choose and input a name for your computer, noted above as $Your_Computer_Name. This will be the name with which your server will appear in your Rapid.Space project.
  IMPORTANT: If the name contains spaces, surround the whole name with double quotes, e.g. "My SlapOS Compute Node".

• Next, input the Compute Node Token you have generated before: $Your_Compute_Node_Token.

• When prompted for the IPv6 network interface, either enter lo or skip the question as you are using Re6st.

• Finally, for the number of SlapOS computer partitions, you can stay with the default of 10 for a small deployment. If you expect a larger deployment, 100 partitions is a safe number, and adds no extra overhead.

NOTE: If you are using copy/paste, beware of whitespace or invisible characters that might be added when pasting your data.

Once the installation has finished without errors, you should see:

...
PLAY RECAP *********************************************************************
127.0.0.1                  : ok=12   changed=4   unreachable=0   failed=0

However, in case the installation fails and you want to start over, you need to request a new Compute Node Token as mentioned above and, depending on whether it is already created, remove any existing configuration at /etc/opt/slapos/slapos.cfg before restarting the installation.

NOTE: If you need more computer partitions after the installation is finished, you can edit the above-mentioned configuration file at /etc/opt/slapos/slapos.cfg: find the partition-amount line in the [slapformat] section, and set it to the desired number.
Save and exit the configuration file, and run the command $ slapos node format --now to update your node with the new changes.

You can verify that SlapOS was installed by trying the above command $ slapos node: you should see a single service running, which is the watchdog.

Next, (re)format the SlapOS node with the command $ slapos node format --now.

Head back to your Rapid.Space Panel.
Either click on Compute Nodes from your Project page or click on Servers from the homepage, and verify that the list of servers now includes your new SlapOS Node which was associated to your network using the Compute Node Token you have generated. You may have to refresh the page for the server to show up.

 NOTE: Clicking on an entry will bring you to the Compute Node's page, where you will be able to see more information about the it. Also, the Status column can have three different colors:

• Green indicates the server is active and successfully contacting the Master.
• Yellow indicates connection issues with the Node or one of its partitions.
• Red means the Node has lost connection entirely.
