Nginx for Unikraft

This is the port of Nginx for Unikraft as external library.

Build

Nginx depends on the following libraries, that need to be added to Makefile in this order:

• pthreads, e.g. pthread-embedded
• libc, e.g. newlib
• network stack, e.g. lwip

Before you proceed to writing your own application, you can use the main() function provided in the Nginx glue code by enabling it in its configuration menu.

Root filesystem

Creating the filesystem

Nginx needs a filesystem which should contain its configuration files, HTML files and log files. Therefore, the filesystem needs to be created before running the VM. You may find such an example in nginx-rootfs-example/ subdirectory.

Using the filesystem

Mounting the filesystem is a transparent operation. All you have to do is to provide the right Qemu parameters in order for Unikraft to mount the filesystem. We will use the 9pfs support for filesystems and for this you will need to use the following parameters:

-fsdev local,id=myid,path=<some directory>,security_model=none \
-device virtio-9p-pci,fsdev=myid,mount_tag=test,disable-modern=on,disable-legacy=off

You should also use vfs.rootdev=test to specify the 9pfs mounting tag to Unikraft. To enable 9pfs, you'll need to select the following menu options, all under Library Configuration:

• uk9p: 9p client
• vfscore: VFS Core Interface → vfscore: Configuration → Automatically mount a root filesysytem → Default root filesystem → 9PFS
• uk library parameter
