It allows the execution of real network functions, packaged as Docker containers, in emulated network topologies running locally on the developer's machine. The emulation platform also offers OpenStack-like APIs for each emulated PoP so that it can integrate with MANO solutions, like OSM.

The easiest way is the automated installation using the OSM installer. The bare-metal installation requires a freshly installed **Ubuntu 18.04 LTS** and is done by an Ansible playbook. Another option is to use a nested Docker environment to run the emulator inside a Docker container. +### Automated OSM installation -#### Run Unit Tests -* `cd ~/son-emu` -* `sudo py.test -v src/emuvim/test/unittests` +This installation option applies if you want to use vim-emu in combination with OSM. +```sh +./install_osm.sh --vimemu +``` -### Building +This command will install OSM as well as the emulator (as a Docker container) on a local machine. It is recommended to use a machine with Ubuntu 18.04 LTS. More details about this installation option can be found in the [OSM wiki](https://osm.etsi.org/wikipub/index.php/VIM_emulator). -Son-emu is entirely written in Python and does not require a special build process. Please check the [Installation](https://github.com/sonata-nfv/son-emu#installation) section for more details about the installation of son-emu. +### Standalone installation -### Dependencies +#### Option 1: Bare-metal installation -Son-emu requires the latest version of [Containernet](https://github.com/mpeuster/containernet) to be installed on the system. +```sh +sudo apt-get install ansible git aptitude +``` -Despite of this son-emu has the following dependencies: +##### Step 1.

The simple one is to use Vagrant to create a VirtualBox-based VM on you machine that contains the pre-installed and configured emulator. The more complicated installation requires a freshly installed Ubuntu 14.04 LTS or 16.04 LTS and is done by a ansible playbook. +#### Option 2: Nested Docker Deployment +This option requires a Docker installation on the host machine on which the emulator should be deployed. -### Vagrant Installation +Build: +```sh +git clone https://osm.etsi.org/gerrit/osm/vim-emu.git +cd ~/vim-emu +# build the container: +docker build -t vim-emu-img . +``` -* Request VirtualBox and Vagrant to be installed on the system. -* `git clone https://github.com/sonata-nfv/son-emu.git` -* `cd ~/son-emu` -* `vagrant up` -* `vagrant ssh` to enter the new VM in which the emulator is installed. +Run: +```sh +# run the (interactive) container: +docker run --name vim-emu -it --rm --privileged --pid='host' -v /var/run/docker.sock:/var/run/docker.sock vim-emu-img /bin/bash +``` -Follow the MOTD in the VM to run the example topology and the dummy-gatekeeper. The dummy-gatekeeper's default port 5000 is forwarded to the host machine and can be accessed from it by using, e.g., curl http://127.0.0.1:5000/packages. - -### Ansible Installation +--- +## Usage -* Requires: Ubuntu 14.04 LTS or 16.04 LTS -* `sudo apt-get install ansible git` -* `sudo vim /etc/ansible/hosts` -* Add: `localhost ansible_connection=local` +### Example -#### 1.
