Configuring SlapOS Client

What is SlapOS Client?

SlapOS client is a set of tools allowing you to manage your SlapOS Nodes, your instances and your SlapOS Master account. It is bundled with the standard SlapOS Node installation.

It will allow you to request and manage your instances, to install Software Release on your nodes, as if you were on, but with all the power of terminal.

Step 0: requirements

  • A GNU/Linux Server
  • slapos-node package installed on the machine. No need for actual node configuration, only the package itself (containing the binaries) are required.
  • A SlapOS Account
  • NO ROOT ACCOUNT IS NEEDED. Don't use root, except if you have a specific reason to do so.

To follow this tutorial, you will need a server with a GNU/Linux distribution, slapos-node package installed and account.

Step 1: Register and obtain a Credential security Token

Go to (or any other SlapOS Master), register if not already done, go to My Account and click on Generate a Credential 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.

Step 2: Run slapos configure client

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

  • slapos configure client 

 This command will generate the following files:

  • $HOME/.slapos/slapos-client.cfg
  • $HOME/.slapos/certificate : Your user SSL Cetificate
  • $HOME/.slapos/key: Your user SSL Private Key

You can now, Edit $HOME/.slapos/slapos-client.cfg to include some aliases: 

alias =

Check certificates

In order to check if certificate is okay (good location, rights, content...), you can run those commands:

To check validity of certificate:

$ /opt/slapos/parts/openssl/bin/openssl x509 -noout -in $HOME/.slapos/client.crt

To check the key:

$ /opt/slapos/parts/openssl/bin/openssl rsa -noout -in $HOME/.slapos/client.key -check

If you see no output or if command states it's okay, well, everything is okay.
