10. ANNEX 2: Reference of OSM Client commands and library

The OSM Client is a client library and a command-line tool (based on Python) to operate OSM, which accesses OSM’s Northbound Interface (NBI) and lets you manage descriptors, VIMs, Network Services, Slices, etc. along with their whole lifecycle. In other words, the OSM Client is a sort of Swiss knife that provides a convenient access to all the functionality that OSM’s NBI offers.

10.1.5. How to install OSM Client in Windows with WSL

OSM client can be easily installed in Windows by installing an Ubuntu distro on Linux with Windows Subsystem for Linux (WSL).

Once WSL is installed with an Ubuntu 20.04 distro, you can install OSM following the instruccions in (#how-to-install-osm-client-in-ubuntu-2004)

10.1.6. How to install OSM Client directly in Windows with Conda and Git

OSM can also be installed in Windows with Miniconda and Git

You can install both programs with Chocolatey, the package manager for Windows. Open a CMD window and run the following commands:

choco install -y git make wget
choco install -y miniconda3

Then, open Windows environment variables > User environment variables, and add the following entries to the Path user environment variable in order to make Conda executables reachable from all terminals:

  • C:\tools\miniconda3

  • C:\tools\miniconda3\Scripts

  • C:\tools\miniconda3\Library\bin

Make sure that aliases for Python are disabled in Windows Configuration. Go to Settings > Apps > Apps & features, and click on “Manage app execution aliases”. Then disable aliases for Python.

Open Git Bash and run the following commands to create a Conda environment with Python 3.8 and initialize all shells to work with Conda:

conda create -n osm-env python=3.8
conda init --all
# Logout

Then install OSM client as follows:

# Install conda and install some packages via conda (which will install dependent libraries)
conda activate osm-env
conda install pycurl==7.45.1

# Upgrade pip to the latest version (with sudo, to install it globally for all users)
python -m pip install -U pip

# Decide which version to use (e.g., v12.0)
export OSM_CLIENT_VERSION=v12.0

# Clone IM repo and checkut the desired version
git clone https://osm.etsi.org/gerrit/osm/IM
git -C IM checkout ${OSM_CLIENT_VERSION}

# Install OSM IM using pip
python -m pip install -r IM/requirements.txt
# make -C IM clean
python -m pip install ./IM

# Clone osmclient repo and checkut the desired version
git clone https://osm.etsi.org/gerrit/osm/osmclient
git -C osmclient checkout ${OSM_CLIENT_VERSION}

# Install osmclient using pip
python -m pip install -r osmclient/requirements.txt
# Required DLLs for python-magic
python -m pip install python-magic-bin
python -m pip install ./osmclient

# Try OSM client
python -m osmclient.scripts.osm
# Logout from Git Bash

Open Git Bash again and edit .bash_profile to activate the Conda environment persistently. If desired, add an alias to osm executable:

conda activate osm-env
alias 'osm=python -m osmclient.scripts.osm'

That will complete OSM client installation for Windows.

10.2. Getting help

Options -h or --helpcan be used globally to know the global options and commands, or after a command to know the specific options and args of a command

$ osm -h
Usage: osm [OPTIONS] COMMAND [ARGS]...

Options:
  --hostname TEXT             hostname of server.  Also can set OSM_HOSTNAME in environment
  --user TEXT                 user (defaults to admin). Also can set OSM_USER in environment
  --password TEXT             password (defaults to admin). Also can set OSM_PASSWORD in environment
  --project TEXT              project (defaults to admin). Also can set OSM_PROJECT in environment
  -v, --verbose               increase verbosity (-v INFO, -vv VERBOSE, -vvv DEBUG)
  --all-projects              include all projects
  --public / --no-public      flag for public items (packages, instances, VIM accounts, etc.)
  --project-domain-name TEXT  project domain name for keystone authentication (default to None). Also can set OSM_PROJECT_DOMAIN_NAME in environment
  --user-domain-name TEXT     user domain name for keystone authentication (default to None). Also can set OSM_USER_DOMAIN_NAME in environment
  -h, --help                  Show this message and exit.

Commands:
  k8scluster-add             adds a K8s cluster to OSM
  ...

$osm vim-create -h
Usage: osm vim-create [OPTIONS]

  creates a new VIM account

Options:
  --name TEXT              Name to create datacenter
  --user TEXT              VIM username
  --password TEXT          VIM password
  --auth_url TEXT          VIM url
  --tenant TEXT            VIM tenant name
  --config TEXT            VIM specific config parameters
  --account_type TEXT      VIM type
  --description TEXT       human readable description
  --sdn_controller TEXT    Name or id of the SDN controller associated to this VIM account
  --sdn_port_mapping TEXT  File describing the port mapping between compute nodes' ports and switch ports
  --wait                   do not return the control immediately, but keep it until the operation is completed, or timeout
  -h, --help               Show this message and exit.

The following video illustrates how it works.

10.3. Interaction from the OSM client to an OSM in a different location

When using the OSM Client from a host different from OSM’s, at a minimum you will need to specify the OSM host, either via an environment variable or via the option --hostname. For instance, you can set your client to access an OSM host running at 10.80.80.5 by using:

export OSM_HOSTNAME="10.80.80.5"

The following video shows how it works.

10.4. Getting OSM version

You can obtain server and client versions, by using the command osm version. Server version corresponds to OSM NBI module.

$ osm version
Server version: 7.0.1.post23 2020-04-17
Client version: 7.0.1rc1.post52+gbcb7833

The following video shows how it works.

10.5. RBAC

10.5.1. Configuring RBAC

OSM supports Role-Based Access Control, so that it’s possible to use users and projects, and each user will have a role in a project. OSM provides CRUD operations (*-create, *-list, *-show, *-update, *-delete) over users, roles and projects

The following video demonstrates how it works.

10.5.2. Using RBAC

When using users and projects, the following environment variables can be used to authenticate against the system:

  • OSM_USER

  • OSM_PASSWORD

  • OSM_PROJECT

  • OSM_PROJECT_DOMAIN_NAME

  • OSM_USER_DOMAIN_NAME

Or instead the command line options --user, --password, --project, --project-domain-name and --user-domain-name can be used:

  --user TEXT                 user (defaults to admin). Also can set OSM_USER in environment
  --password TEXT             password (defaults to admin). Also can set OSM_PASSWORD in environment
  --project TEXT              project (defaults to admin). Also can set OSM_PROJECT in environment
  --project-domain-name TEXT  project domain name for keystone authentication (default to None). Also can set OSM_PROJECT_DOMAIN_NAME in environment
  --user-domain-name TEXT     user domain name for keystone authentication (default to None). Also can set OSM_USER_DOMAIN_NAME in environment

In addition, the option --all-projects allow users to perform operations in all the projects they belong to (e.g. osm --all-projects nfpkg-list will show all the NF packages in all projects the user belongs to). Finally, the option --public allows to create public items, making them available in all projects; visibility from the client of those public items in *-list and *-show operations requires the use of the option --public.

  --all-projects              include all projects
  --public / --no-public      flag for public items (packages, instances, VIM accounts, etc.)

The following video shows a complete demo using different users and projects, and some of these options, illustrating the different project visibility.

10.6. OSM repositories

OSM support repositories where NF and NS packages can be retrieved. The following commands can be used to add a repo, list the packages in a repo, show their details or onboard them in OSM:

  • osm repo-add NAME URI: adds a VNF/NS catalog repo

  • osm nfpkg-repo-listand osm nspkg-repo-list: lists NF/NS packages from OSM repositories

  • osm nfpkg-repo-show|nspkg-repo-show --repo <REPO_NAME>: shows a specific NF/NS package in a repo

  • osm nfpkg-create|nspkg-create --repo <REPO_NAME> <OSM_PKG>: onboards a package from a repo into OSM

osm repo-add --description "OSM VNF and NS repository" vnfrepo https://osm-download.etsi.org/ftp/vnf-catalog/
osm nfpkg-repo-list
osm nfpkg-repo-show --repo vnfrepo fb_magma_knf
osm nfpkg-create --repo vnfrepo fb_magma_knf
osm nspkg-repo-list
osm nspkg-repo-show --repo vnfrepo fb_magma_ns
osm nspkg-create --repo vnfrepo fb_magma_ns

The following video demonstrates how these commands work.

10.7. Package creation tools

There are several utilities in the OSM client to simplify VNF and NS package creation:

  • osm package-create PACKAGE_TYPE PACKAGE_NAME: creates an OSM VNF, NS or NST package

  • osm package-validate PKG_FOLDER: validates descriptors given a base directory

  • osm package-build PKG_FOLDER: builds the package NS, VNF given the package_folder (descriptor validation, charm build, checksum generation, tar.gz creation)

  • osm nfpkg-create|nspkg-create PKG_FOLDER: validates the package, builds it and onboards it into OSM

The following video illustrates the previous commands.

10.8. Advanced onboarding

Commands for onboarding NF, NS and NST (nfpkg-create, nspkg-create and nst-create) have the option --override to override the fields in the descriptor whem uploading the package to OSM. The format of the option is the following:

  --override TEXT      overrides fields in descriptor, format: "key1.key2...=value[;key3...=value;...]"

In addition, VNF onboarding allows these additional options:

  • --override-epa: adds guest-epa parameters to all VDU. Useful to onboard packages to be deployed in an EPA-only VIM

  • --override-nonepa: removes all guest-epa parameters from all VDU. Useful to onboard EPA-based VNF packages to be deployed in a non-EPA VIM

  • --override-paravirt: overrides all VDU interfaces to PARAVIRT. Useful if packages are going to be deployed in a VIM that does not support SR-IOV or PCI-PASSTHROUGH interfaces.

The following video demonstrates how these options work.

10.9. Filtering requests

Some commands have the option --filter that allows to filter Read operations (*-list, *-show) to restric the output to the items matching de filter. Below an example for osm ns-list:

$ osm ns-list -h
Usage: osm ns-list [OPTIONS]

  list all NS instances

  Options:
    --filter filterExpr    Restricts the list to the NS instances matching the filter

  filterExpr consists of one or more strings formatted according to "simpleFilterExpr",
  concatenated using the "&" character:

      filterExpr := <simpleFilterExpr>["&"<simpleFilterExpr>]*
      simpleFilterExpr := <attrName>["."<attrName>]*["."<op>]"="<value>[","<value>]*
      op := "eq" | "neq" | "gt" | "lt" | "gte" | "lte" | "cont" | "ncont"
      attrName := string
      value := scalar value

  where:
    * zero or more occurrences
    ? zero or one occurrence
    [] grouping of expressions to be used with ? and *
    "" quotation marks for marking string constants
    <> name separator

  "AttrName" is the name of one attribute in the data type that defines the representation
  of the resource. The dot (".") character in "simpleFilterExpr" allows concatenation of
  <attrName> entries to filter by attributes deeper in the hierarchy of a structured document.
  "Op" stands for the comparison operator. If the expression has concatenated <attrName>
  entries, it means that the operator "op" is applied to the attribute addressed by the last
  <attrName> entry included in the concatenation. All simple filter expressions are combined
  by the "AND" logical operator. In a concatenation of <attrName> entries in a <simpleFilterExpr>,
  the rightmost "attrName" entry in a "simpleFilterExpr" is called "leaf attribute". The
  concatenation of all "attrName" entries except the leaf attribute is called the "attribute
  prefix". If an attribute referenced in an expression is an array, an object that contains a
  corresponding array shall be considered to match the expression if any of the elements in the
  array matches all expressions that have the same attribute prefix.

  Filter examples:
     --filter  admin-status=ENABLED
     --filter  nsd-ref=<NSD_NAME>
     --filter  nsd.vendor=<VENDOR>
     --filter  nsd.vendor=<VENDOR>&nsd-ref=<NSD_NAME>
     --filter  nsd.constituent-vnfd.vnfd-id-ref=<VNFD_NAME>

10.10. Debugging

Option -v can be used to debug OSM client. There are different verbosity levels:

  • -v: log level INFO, shows API calls

  • -vv: log level VERBOSE, shows API calls and content response

  • -vvv: log level DEBUG, shows the different methods the client is going through

The following video illustrates the log detail for each verbosity level.

10.11. Other useful options

Some commands present useful options:

  • --literal: shows output in YAML format. It might be deprecated in the future in favour of a new option -o OUTPUT_FORMAT.

  • --wait: makes the command synchronous

  • --long: shows more info

10.12. Aliases

The following are command aliases with identical behaviour:

  • For CRUD operations over NF packages, there are different command aliases. The preferred commands is nfpkg-*. The command vnfd-*might be deprecated in the future.

    • nfpkg-create|vnfpkg-create|vnfd-create: creates a new NFpkg

    • nfpkg-delete|vnfpkg-delete|vnfd-delete: deletes a NFpkg

    • nfpkg-list|vnfpkg-list|vnfd-list: list all xNF packages (VNF, HNF, PNF)

    • nfpkg-show|vnfpkg-show|vnfd-show: shows the details of a NF package

    • nfpkg-update|vnfpkg-update|vnfd-update: updates a NFpkg

  • For CRUD operations over NS packages, there are different command aliases. The preferred commands is nspkg-*. The command nsd-*might be deprecated in the future.

    • nsd-create|nspkg-create: creates a new NSD/NSpkg

    • nsd-delete|nspkg-delete: deletes a NSD/NSpkg

    • nsd-list|nspkg-list: list all NS packages

    • nsd-show|nspkg-show: shows the details of a NS package

    • nsd-update|nspkg-update: updates a NSD/NSpkg

  • For CRUD operations over Network Slice Templates, the following command aliases exist:

    • netslice-template-create|nst-create: creates a new Network Slice Template (NST)

    • netslice-template-delete|nst-delete: deletes a Network Slice Template (NST)

    • netslice-template-list|nst-list: list all Network Slice Templates (NST)

    • netslice-template-show|nst-show: shows the content of a Network Slice Template (NST)

    • netslice-template-update|nst-update: updates a Network Slice Template (NST)

10.13. Enable autocompletion

You can enable autocompletion in OSM client by creating a file osm-complete.sh in the following way:

mkdir -p $HOME/.bash_completion.d
_OSM_COMPLETE=bash_source osm > $HOME/.bash_completion.d/osm-complete.sh

Then you can add the following to your $HOME/.bashrc file:

. .bash_completion.d/osm-complete.sh

10.14. Using osmclient as a library to interact with OSM

Assuming that you have installed python-osmclient package, it’s pretty simple to write some Python code to interact with OSM.

10.14.1. Simple Python code to get the list of NS packages

from osmclient import client
from osmclient.common.exceptions import ClientException
hostname = "127.0.0.1"
myclient = client.Client(host=hostname, sol005=True)
resp = myclient.nsd.list()
print yaml.safe_dump(resp)

10.14.2. Simple Python code to get the list of VNF packages from a specific user and project

The code will print for each package a pretty table, then the full details in yaml

from osmclient import client
from osmclient.common.exceptions import ClientException
import yaml
from prettytable import PrettyTable
hostname = "127.0.0.1"
user = admin
password = admin
project = admin
kwargs = {}
if user is not None:
    kwargs['user']=user
if password is not None:
    kwargs['password']=password
if project is not None:
   kwargs['project']=project
myclient = client.Client(host=hostname, sol005=True, **kwargs)
resp = myclient.vnfd.list()
print yaml.safe_dump(resp)
