You can absolutely install the wasm shim without Desktop. (They won't tell you that because Desktop is a revenue stream for Mirantis.)

In your VM or WSL instance that's running Docker, get the shim from here: https://github.com/deislabs/containerd-wasm-shims (You might need to build it yourself)

Then specify the --runtime and --platform arguments like instructed in the doc, but with a slight modification:

    --runtime=containerd-wasm-shim=/path/to/containerd/wasm/shim
This works because most container runtimes are self-contained Go binaries. Haven't used the wasm runtime yet, so not sure if that is true for this runtime as well.

If one wants to use exactly the same command line, then one could compile https://github.com/second-state/runwasi, and place the compiled shim in the correct path.

The difference vs deislabs shims you linked or vs the containerd/runwasi (formerly deislabs/runwasi) is the exact wasm runtime used.

secondstate (that Docker Desktop includes) uses WasmEdge, containerd/runwasi uses wasmtime, and deislabs/containerd-wasm-shims uses Fermyon Spin or SpiderLighting depending on which shim you use.
