Quick Start

You can install Cherry on Docker or natively from source based on your preference.

Installing on Docker

Install Docker if you don't have it on your system by following instruction: https://docs.docker.com/installation/
Clone Cherry:

$ git clone https://github.com/superkkt/cherry.git

Copy the template configuration:

$ sudo cp cherry/cherry.yaml /usr/local/etc

Edit the configuration file /usr/local/etc/cherry.yaml as you want.
Build Docker image as root:

# cd cherry; docker build -t cherry .

Run as root:

# docker run -d -p 6633:6633 -v /dev/log:/dev/log -v /your/config/cherry.yaml:/usr/local/etc/cherry.yaml cherry

The bind mount of /dev/log is to collect syslog messages from the container and then write to the host's syslog daemon.

That's it! Cherry will be started in L2 switch mode.

Installing from source

Install Go language if you don't have it on your system by following instruction: http://golang.org/doc/install
Clone and compile Cherry:

$ go get github.com/superkkt/cherry

Copy the compiled binary and template configuration:

$ sudo cp $GOPATH/bin/cherry /usr/local/bin

$ sudo cp $GOPATH/src/github.com/superkkt/cherry/cherry.yaml /usr/local/etc

Edit the configuration file /usr/local/etc/cherry.yaml as you want.
Run:

$ /usr/local/bin/cherry &

That's it! Cherry will be started in L2 switch mode.
