Examples from the 3rd OSM Hackfest

Work material

Examples

Basic VNF and NS


  • Creating VNF with the client

VNF1.JPG

   •Generate skeleton folder (VNF with only 1 VDU):
       /usr/share/osm-devops/descriptor-packages/tools/generate_descriptor_pkg.sh-t vnfd --image ubuntu1604 -c hackfest1
   •Go to hackfest1_vnfd folder and edit the descriptor:
       Use the IM tree representation of VNFD as a reference (http://osm-download.etsi.org/ftp/osm-doc/vnfd.html)
  • Editing the VNF descriptor

  • Validate the VNF descriptor and generate VNF package
   •Validate VNF descriptor
       /usr/share/osm-devops/descriptor-packages/tools/validate_descriptor.py <DESCRIPTOR_FILE>
   •Generate VNF package(from parent folder)
       /usr/share/osm-devops/descriptor-packages/tools/generate_descriptor_pkg.sh -t vnfd -N <VNFD_FOLDER>    
  • Creating the NS with the client

   •Generate skeleton folder (NS with only 1 VNF)
       /usr/share/osm-devops/descriptor-packages/tools/generate_descriptor_pkg.sh -t nsd -c hackfest1
   •Go to hackfest1_nsd folder and edit the descriptor:
       Use the IM tree representation of VNFD as a reference (http://osm-download.etsi.org/ftp/osm-doc/nsd.html)
  • Editing the NS descriptor

  • Validate the NS descriptor and generate NS package
   •Validate NS descriptor
       /usr/share/osm-devops/descriptor-packages/tools/validate_descriptor.py <DESCRIPTOR_FILE>
   •Generate NS package (from parent folder)
       /usr/share/osm-devops/descripto-rpackages/tools/generate_descriptor_pkg.sh -t nsd -N <NSD_FOLDER>
  • Adding VNF and NS packages
    •VNF package: 
       •osm vnfd-list
       •osm vnfd-create hackfest1_vnfd.tar.gz
       •osm vnfd-show hackfest1-vnf
       •osm vnfd-delete ...
    •NS package 
       •osm nsd-list
       •osm nsd-create hackfest1_nsd.tar.gz
       •osm nsd-show hackfest1-ns
       •osm vnfd-delete ...
    •Generating an SSH key pair to access to VNFs later
       •ssh-keygen
  • Deploying NS with the client or UI
   •Client 
       •osm ns-list
       •osm ns-create --ns_name hf1 --nsd_name hackfest1-ns \
       --vim_account <VIM_ACCOUNT_NAME>|<VIM_ACCOUNT_ID> \
       --ssh_keys <KEY1_PUBKEY_FILE> \
       --config '{vld: [ {name: mgmtnet, vim-network-name: <VIM_MGMT_NAME>} ] }'
       •osm ns-show hf1
       •osm ns-delete ...
       •Check VNF instances to see the instance and get the mgmt IP address of the VNF
           •osm vnf-list
           •osm vnf-show ...
        •Connect to the VNF
            •ssh -i <priv_key> ubuntu@<IP>
   •UI
       •Go to NS packages
       •In hackfest1-ns, click in “Actions: Instantiate NS”
       • Complete the form
           • Add a name to the NS instance
           • Select the Datacenter where the NS will be deployed
           • Specify in the config section a default VIM network name to map “mgmtnet”:
                   • {vld: [ {name: mgmtnet, vim-network-name: <VIM_MGMT_NAME>} ] }
                   • mgmt (openstack1)
                   • external (openstack3)
                   • public (openstack4)
           • Paste your SSH key
        •Go to VNF instances to see the instance and get the mgmt IP address of the VNF
        •Connect to the VNF:
            •ssh -i <priv_key> ubuntu@<IP>
    

Multi-VDU VNF


VNF with Day-0 configuration

VNF with EPA requirements

VNF with Day-1/Day-2 configuration (adding a charm)
