Use SlapOS Client

This document describes how to use the SlapOS client, a utility software to manage SlapOS nodes, instances and the SlapOS Master account on the command line. It is a bare Python console with several global variables defined and initialized so it can interact with a SlapOS Master through the SLAP Library.

To use the SlapOS Client you need a GNU/Linux Server with SlapOS Node installed from packages. It is not necessary to configure this machine as a compute node, the package itself with the respective binaries is all that is required. You will also need a X509 security token from a SlapOS Master (you can use Rapid.Space or create your own SlapOS Master).

Please follow rapidspace-HowTo.Setup.SlapOS.Client page to get a working SlapOS client.

Available commands

The SlapOS client has a few CLI commands directly available and it also has a "console" mode which is a python console with available commands to talk to the SlapOS master.

The list of commands is:

  • slapos service list
  • slapos service info
  • slapos computer list
  • slapos computer info
  • slapos supply
  • slapos remove
  • slapos request
  • slapos console (the python console)

In order to view the help on a command just add "help" after slapos (e.g. slapos help service info).

Example of service info

$ slapos service info ors48-core-network

SlapOS console: start the console

slapos console # by default it uses ~/.slapos/slapos-client.cfg but you can launch with "slapos console --cfg XXXXX"

Please note that as regular python, the "slapos console" tool can be run interactively or can execute code from a file.

$ slapos console
2025-03-27 23:04:01 slapos[1357312] INFO IPython not available - using plain Python shell

SlapOS console: API

Here is a list of available methods:

  • supply
  • request
  • remove

The following methods are available on a SlapOS Client (full api):

  • supply() is shorthand for slap.registerSupply().supply() and allows to request installation of a software on a node.
  • request() is shorthand for slap.registerOpenOrder().request() and allows to request instances of a software installation on a node.
  • remove() uninstalls a software from a node

Example Usage

# supply software installation on a node
SR-kvm = https://lab.nexedi.com/nexedi/slapos/-/raw/1.0.404/software/kvm/software.cfg
supply(SR-kvm, "mycomputer")

# request instance on arbitrary node
request(SR-kvm, "myuniquekvm")

# request instance on specific node
request(SR-kvm, "myotheruniquekvm", filter_kw = {
  "computer_guid": "COMP-12345"
})

# request instance, specifying parameters
request(SR-kvm, "mythirduniquekvm", partition_parameter_kw = {
  "nbd_ip":"2a01:e35:2e27:460:e2cb:4eff:fed9:48dc", "nbd_port":"1024"
})
# fetch existing instance status
request(SR-kvm, "myuniquekvm").getState()

# fetch instance information from launched instance
request(SR-kvm, "myuniquekvm").getConnectionParameter("url")
