Setting your ENV Variables¶
The Vagrant File used in the VPP repo sets the configuration options based on your ENV (environment) variables, or to default the configuration at specified values if your ENV variables are not initialized (if you did not run the env.sh script found below).
This is the env.sh script found in vpp/extras/vagrant. When run, the script sets ENV variables using the export command.
export VPP_VAGRANT_DISTRO="ubuntu1604" export VPP_VAGRANT_NICS=2 export VPP_VAGRANT_VMCPU=4 export VPP_VAGRANT_VMRAM=4096
In the Vagrant File, you can see these same ENV variables used (discussed on the next page).
Adding your own ENV variables is easy. For example, if you wanted to setup proxies for your VM, you would add to this file the export commands found in the building VPP commands section. Note that this only works if the ENV variable is defined in the Vagrant File.
Once you’re finished with env.sh script, and you are in the directory containing env.sh, run the script to set the ENV variables with:
$ source ./env.sh
