Running WASM on K8s (WIP)

"Wanna be" running WASM on K8s - but probably first try it on Docker Desktop (still in Beta ATM)

Prerequisites

Follow emscripten install instruction here.

To be able to run it using Docker, please follow the instructions here.

Deployments

Native

Compile your C code and run it using:

gcc hello.c -o hello.out
./hello.out

Wasm

NOTE: ./emcc script can be found in emsdk/emscripten directory.

./emcc hello.c -o hello.wasm

Then you can run WASM script using WasmEdge runtime:

wasmedge --enable-all-statistics hello.wasm

In Docker

First build the Dockerfile and push the images using the following commands:

docker build -t <username>/hello-world-c -f Dockerfile .
docker push <username>/hello-world-c

# WASM in Container
docker buildx build --platform wasi/wasm -t <username>/hello-world-wasm .
docker push <username>/hello-world-wasm

Then simply run the following command:

docker run <username>/hello-world-c

# Just for testing - not used for benchmarking
docker run \
  --runtime=io.containerd.wasmedge.v1 \
  --platform=wasi/wasm \
  <username>/hello-world-wasm
