package: slapos.coreconsoleThe slapconsole tool allows to interact with a SlapOS Master throught the SLAP
library.For more information about SlapOS or slapconsole usages, please go tohttps://slapos.nexedi.com.The slapconsole tool is only a bare Python console with several global variables
defined and initialized.Initialization and configuration fileSlapconsole allows to automatically connect to a Master using URL and SSL
certificate from given slapos.cfg.
Certificate has to beUSERcertificate, manually obtained from SlapOS master
web interface.Slapconsole tools reads the given slapos.cfg configuration file and use the
following informations :Master URL is read from [slapos] in the “master_url” parameter.SSL Certificate is read from [slapconsole] in the “cert_file” parameter.SSL Key is read from [slapconsole] in the “key_file” parameter.See slapos.cfg.example for examples.Global functions/variables“request()” is a shorthand for slap.registerOpenOrder().request() allowing
to request instances.“supply()” is a shorthand for slap.registerSupply().supply() allowing to
request software installation.For more information about those methods, please read the SLAP library
documentation.“product” is an instance of slap.SoftwareProductCollection whose only goal is to retrieve
the URL of the best Software Release of a given Software Product as attribute.
for each attribute call, it will retrieve from the SlapOS Master the best
available Software Release URL and return it.This allows to request instances in a few words, i.e:request("http://www.url.com/path/to/current/best/known/kvm/software.cfg", "mykvm")can be simplified intorequest(product.kvm, "mykvm")“slap” is an instance of the SLAP library. It is only used for advanced usages.
“slap” instance is obtained by doingslap = slapos.slap.slap()

accordingly. The variables are number of partitions, IP addresses, storages
and network interfaces.Format uploads a into configured SlapOS Master server.Format dumps allocated resources for the partition into a JSON file per
partition ~/.slapos-resource. This file contains network interfaces,
IP address ranges and port ranges. The resource constraints can be
recursively folded.Pluggable parts for formatting are available too. They are called Managers
and can be turned on/off via configuration property manager_list.This program shall be only run by root.RequirementsLinux with IPv6 and tap interface support.Binaries:groupaddipuseraddgridWarningThis section is outdated,slapgridcommand was reorganised inslapossub-commands.slapgrid is a client of SlapOS. SlapOS provides support for deploying a SaaS
system in a minute.
Slapgrid allows you to easily deploy instances of softwares based on buildout
profiles.
For more informations about SLAP and SlapOS, please see the SLAP documentation.RequirementsA working SLAP server with informations about your computer, in order to
retrieve them.As Vifib servers use IPv6 only, we strongly recommend an IPv6 enabled UNIX
box.For the same reasons, Python >= 2.6 with development headers is also strongly
recommended (IPv6 support is not complete in previous releases).For now, gcc and glibc development headers are required to build most software
releases.ConceptsHere are the fundamental concepts of slapgrid :
A Software Release (SR) is just a software.
A Computer Partition (CP) is an instance of a Software Release.
Imagine you want to install with slapgrid some software and run it. You will
have to install the software as a Software Release, and then instantiate it,
i.e configuring it for your needs, as a Computer Partition.How it worksWhen run, slapgrid will authenticate to the SLAP library with a computer_id and
fetch the list of Software Releases to install or remove and Computer
Partitions to start or stop.
Then, it will process each Software Release, and each Computer Partition.
It will also periodically send to SLAP the usage report of each Computer
Partition.InstallationWith easy_install:$ easy_install slapgridslapgrid needs several directories to be created and configured before being
able to run : a software releases directory, and an instances directory with
configured computer partition directory(ies).
You should create for each Computer Partition directory created a specific user
and associate it with its Computer Partition directory. Each Computer Partition
directory should belongs to this specific user, with permissions of 0750.Usageslapgrid needs several informations in order to run. You can specify them by
adding arguments to the slapgrid command line, or by putting then in a
configuration file.
Beware : you need a valid computer resource on server side.Examplessimple example :
Just run slapgrid:$ slapgrid –instance-root /path/to/instance/root –software-root
/path/to/software_root –master-urlhttps://some.server/some.resource–computer-id my.computer.idconfiguration file example:[slapgrid]
instance_root = /path/to/instance/root
software_root = /path/to/software/root
master_url = https://slapos.server/slap_service
computer_id = my.computer.idthen run slapgrid:$ slapgrid --configuration-file = path/to/configuration/fileslapos.managerManager is a plugin-like class that is being run in multiple phases of slapos node lifecycle.format, manager can format additionally the underlaying OSsoftware, manager can react on software installationinstance, manager can update instance runtime frequentlyConstructor will receive configuration of current stage. Then each method receives
object most related to the current operation. For details see <slapos/manager/interface.py>.In code, a list of manager instances can be easily retreived byfrom slapos import manager
manager_list = manager.from_config(config)Wherefrom_configextracts “manager_list” item from dict-likeconfigargument
and then dynamically loads modules named according to the configuration insideslapos.managerpackage. The manager must be a class named Manager and implementing
interfaceslapos.manager.interface.IManager.Managers might require a list of user for whom they are allowed to perform tasks.
This list of users is given by “power_user_list” in [slapos] section in the
config file.proxyImplement minimalist SlapOS Master server without any security, designed to work
only from localhost with one SlapOS Node (a.k.a Computer).It implements (or should implement) the SLAP API, as currently implemented in
the SlapOS Master (see slaptool.py in Master).The only behavioral difference from the SlapOS Master is:When the proxy doesn’t find any free partition (and/or in case of slave
instance, any compatible master instance), it will throw a NotFoundError (404).slapSimple Language for Accounting and Provisioning python library.How it worksThe SLAP main server which is in charge of service coordination receives from participating servers the number of computer paritions which are available, the type of resource which a party is ready provide, and request from parties for resources which are needed.Each participating server is identified by a unique ID and runs a slap-server daemon. This daemon collects from the main server the installation tasks and does the installation of resources, then notifies the main server of completion whenever a resource is configured, installed and available.The data structure on the main server is the following:A - Action: an action which can happen to provide a resource or account its usageCP - Computer Partition: provides a URL to Access a Cloud ResourceRI - Resource Item: describes a resourceCI - Contract Item: describes the contract to attach the DL to (This is unclear still)R - Resource: describes a type of cloud resource (ex. MySQL Table) is published on slapgrid.orgDL - Delivery Line: Describes an action happening on a resource item on a computer partitionD - Delivery: groups multiple Delivery Lines
