Add catalog-core application to run mccutchen/go-httpbin as a Linux ELF via app-elfloader with lwIP networking. It includes rootfs Docker build, initrd packaging and detailed instructions in README.md for building and running the application on QEMU and Firecracker.

Commit history was squashed to a single commit. Earlier force-pushes were from amending locally and me constantly changing my mind on what the best commit message is. :) |

There was a problem hiding this comment.
Make the commit message wrap to 72 lines. Use "instructions" instead of "instructis" in the commit message.
If the application is httpbingo, name the directory accordingly: bincompat-go-httpbingo.
Use a proper name for authorship and for signed-off-by. Use Firstname Lastname <email>. Do not use Criss-Ivana.
Copy-pasting the commands doesn't work:
./setup.sh
make -C rootfs clean
make -C rootfs
./workdir/unikraft/support/scripts/mkcpio initrd.cpio ./rootfs/
make
sudo ip link set dev virbr0 down || true
sudo ip link del dev virbr0 || true
sudo ip link add dev virbr0 type bridge
sudo ip address add 172.44.0.1/24 dev virbr0
