VIM emulator walkthrough with OSM classic build
Step 1: Install OSM rel. THREE and vim-emu
Install OSM rel. THREE together with the emulator (if not yet done).
$ ./install_osm.sh --lxdimages --vimemu
(Optional) Step 1.1: Manually start vim-emu container
The installation automatically starts a Docker container named vim-emu that runs the emulation platform. If you want to start the emulator manually, you can do this with the following command:
$ sudo docker run --name vim-emu -t -d --rm --privileged --pid='host' -v /var/run/docker.sock:/var/run/docker.sock vim-emu-img python examples/osm_default_daemon_topology_2_pop.py
Step 1.2: Configure environment
You need to set the correct environment variables (they are also printed at the end of the installation script).
$ export OSM_HOSTNAME=`lxc list | awk '($2=="SO-ub"){print $6}'`
$ export OSM_RO_HOSTNAME=`lxc list | awk '($2=="RO"){print $6}'`
$ export VIMEMU_HOSTNAME=$(sudo docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' vim-emu)
Step 2: Check vim-emu that is running inside a Docker container
# connect to vim-emu Docker container to see its logs ( do in another terminal window) $ sudo docker logs -f vim-emu # check if the emulator is running in the container $ sudo docker exec vim-emu vim-emu datacenter list +---------+-----------------+----------+----------------+--------------------+ | Label | Internal Name | Switch | # Containers | # Metadata Items | +=========+=================+==========+================+====================+ | dc2 | dc2 | dc2.s1 | 0 | 0 | +---------+-----------------+----------+----------------+--------------------+ | dc1 | dc1 | dc1.s1 | 0 | 0 | +---------+-----------------+----------+----------------+--------------------+
Step 3: Attach OSM to vim-emu
# connect OSM to emulated VIM $ osm vim-create --name emu-vim1 --user username --password password --auth_url http://$VIMEMU_HOSTNAME:6001/v2.0 --tenant tenantName --account_type openstack # list vims $ osm vim-list +----------+--------------------------------------+ | vim name | uuid | +----------+--------------------------------------+ | emu-vim1 | a8175948-efcf-11e7-94ad-00163eba993f | +----------+--------------------------------------+
Step 4: On-board example pingpong service
# VNFs $ osm upload-package vim-emu/examples/vnfs/ping.tar.gz $ osm upload-package vim-emu/examples/vnfs/pong.tar.gz # NS $ osm upload-package vim-emu/examples/services/pingpong_nsd.tar.gz # You can now check OSM's Launchpad to see the VNFs and NS in the catalog. Or: $ osm vnfd-list +-----------+------+ | vnfd name | id | +-----------+------+ | ping | ping | | pong | pong | +-----------+------+ $ osm nsd-list +----------+----------+ | nsd name | id | +----------+----------+ | pingpong | pingpong | +----------+----------+
Step 5: Instantiate example pingpong service
$ osm ns-create --nsd_name pingpong --ns_name test --vim_account emu-vim1
Step 6: Check service instance
# using OSM client $ osm vnf-list +----------------------------+--------------------------------------+--------------------+-------------------+ | vnf name | id | operational status | config status | +----------------------------+--------------------------------------+--------------------+-------------------+ | default__test__pong__2 | 788fd000-c0f2-4921-ace1-54646b804c9d | pre-init | config-not-needed | | default__test__ping__1 | 8cf2db31-58de-4454-85af-864a968846cf | pre-init | config-not-needed | +----------------------------+--------------------------------------+--------------------+-------------------+ $ osm ns-list +------------------+--------------------------------------+--------------------+---------------+ | ns instance name | id | operational status | config status | +------------------+--------------------------------------+--------------------+---------------+ | test | ea746088-efcf-11e7-bef9-005056b887c5 | running | configured | +------------------+--------------------------------------+--------------------+---------------+ # using vim-emu client $ sudo docker exec vim-emu vim-emu compute list +--------------+----------------------------+---------------+------------------+-------------------------+ | Datacenter | Container | Image | Interface list | Datacenter interfaces | +==============+============================+===============+==================+=========================+ | dc1 | dc1_test.ping.1.ubuntu | ubuntu:trusty | ping0-0 | dc1.s1-eth2 | +--------------+----------------------------+---------------+------------------+-------------------------+ | dc1 | dc1_test.pong.2.ubuntu | ubuntu:trusty | pong0-0 | dc1.s1-eth3 | +--------------+----------------------------+---------------+------------------+-------------------------+
Step 7: Interact with deployed VNFs
# connect to ping VNF container (in another terminal window): $ sudo docker exec -it mn.dc1_test.ping.1.ubuntu /bin/bash
# show network config

Step 8: Shut down
