Open-source developer Joel Severin today announced his work on porting the Linux kernel to WebAssembly and has successffully gotten the kernel up and running within WASM-capable web browsers.
This WebAssembly port of the Linux kernel is up and running basic programs from a shell within a web browser. But there are stability issues and it didn’t take me long either to trigger crashes for this Linux kernel WASM port when running within Google Chrome.
Why not just use docker/k8s then and even be able to control those containers via hypervisor?
Because WASM is a VM in terms of isolation.
Docker is just chroot with marketing (and tooling & ecosystem).
So, the idea of wasm is something that could actually run anywhere, without everything required to prop up a docker/k8s runtime
