Example of how to run nginx via ldp and vcl on top of vpp's host stack.
VPP configuration
In addition to the typical startup config parameters, the host stack requires the ones lower for enabling the use of memfds segments for vpp message queues and to configure the binary api socket transport. For a list of startup parameters see here.
session { evt_qs_memfd_seg }
socksvr { socket-name /tmp/vpp-api.sock}
Nginx
First start vpp and ensure that the network to the http client is working as expected. Then define the following environment variables with the appropriate paths
VCL_CFG=/path/to/vcl.conf LDP_PATH=/path/to/vpp/build-root/build-vpp-native/vpp/lib/libvcl_ldpreload.so
And create a minimal startup configuration in /path/to/vcl.conf like the one lower:
vcl {
heapsize 64M
rx-fifo-size 4000000
tx-fifo-size 4000000
api-socket-name /tmp/vpp-api.sock
}
The above configures vcl to request 4MB receive and transmit fifo sizes and it provides the path to vpp's binary api socket.
To start nginx:
sudo LD_PRELOAD=$LDP_PATH VCL_CONFIG=$VCL_CFG nginx -c nginx.conf
