I've updated the Node binaries for Rumprun on unikernel.teksilo.com. Versions 4.3.0 (LTS) and 5.6.0 are now available.
First, you'll need to upgrade dtuf: $ pip install --upgrade python-dtuf (The reason is that I've upgraded teksilo's Docker registry to v2.3.0. This version of the registry has a new manifest schema (v2). I've decided to drop support for schema v1 because I have no legacy to support and if I do it now then I won't have to do the compatibility dance forever.) If you haven't already set up trust for my Node repo, then do so (make sure you're happy this is my public key): $ pkey_url= https://raw.githubusercontent.com/davedoesdev/dtuf-keys/master/unikernel.teksilo.com/teksilo/node/root_key.pub $ curl $pkey_url | dtuf pull-metadata teksilo/node - Otherwise you can just: $ dtuf pull-metadata teksilo/node You should see a list of files you haven't downloaded yet, e.g. 5.3.0-x86_64-rumprun-netbsd-hw_generic 5.6.0-x86_64-rumprun-netbsd-hw_generic 4.2.4-x86_64-rumprun-netbsd-hw_generic 4.3.0-x86_64-rumprun-netbsd-hw_generic Download one and run it: $ dtuf pull-target teksilo/node 4.3.0-x86_64-rumprun-netbsd-hw_generic > node $ qemu-system-x86_64 -enable-kvm -m 256 -kernel node -append '{"cmdline": "node"}' This should display "Hello, Rump!". You can also pass a filesytem containing a Node application. For example, to run the Express "Hello World" example: $ curl -L https://github.com/strongloop/express/archive/4.13.3.tar.gz | tar -zx $ (cd express-4.13.3; npm install) $ genisoimage -l -r -o express.iso express-4.13.3 $ qemu-system-x86_64 -enable-kvm -m 256 -kernel node -drive if=virtio,file=express.iso -net nic,model=virtio -net user,hostfwd=tcp::3000-:3000 -append '{"net": {"if": "vioif0",, "type": "inet",, "method":"dhcp"},, "blk": {"source": "dev",, "path": "/dev/ld0a",, "fstype": "blk",, "mountpoint": "/express"},, "cmdline": "node /express/examples/hello-world/index.js"}' And point your browser to http://localhost:3000. For some fun examples, see https://github.com/rumpkernel/rumprun-packages/tree/master/nodejs#some-fun-examples but you should be able run any Node application which doesn't rely on native add-ons. I hope to have Ghost (https://ghost.org/) available as a Rumprun binary soon.
