python example (x86_64)

Convert to WASI

Convert the image to WASM

$ c2w python:3.11-slim /tmp/out/out.wasm

Run it on the runtime:

$ wasmtime -- /tmp/out/out.wasm python3 -c "print ('hello world')"
hello world

This passes -c "print ('hello world')" argument to python3 (CMD of this image) and hello world is printed.

Run WASI image on browser

The following runs the WASI-converted container image on browser.

Run this at the project repo root directory.

$ c2w python:3.11-slim /tmp/out-js2/htdocs/out.wasm
$ cp -R ./examples/wasi-browser/* /tmp/out-js2/ && chmod 755 /tmp/out-js2/htdocs
$ docker run --rm -p 8080:80 \
         -v "/tmp/out-js2/htdocs:/usr/local/apache2/htdocs/:ro" \
         -v "/tmp/out-js2/xterm-pty.conf:/usr/local/apache2/conf/extra/xterm-pty.conf:ro" \
         --entrypoint=/bin/sh httpd -c 'echo "Include conf/extra/xterm-pty.conf" >> /usr/local/apache2/conf/httpd.conf && httpd-foreground'

You can run the container on browser via localhost:8080.

Please see wasi-browser example for details about WASI-on-browser.

$ cp -R ./examples/emscripten/* /tmp/pythonjs/ && chmod 755 /tmp/pythonjs/htdocs
$ docker run --rm -p 8080:80 \
         -v "/tmp/pythonjs/htdocs:/usr/local/apache2/htdocs/:ro" \
         -v "/tmp/pythonjs/xterm-pty.conf:/usr/local/apache2/conf/extra/xterm-pty.conf:ro" \
         --entrypoint=/bin/sh httpd -c 'echo "Include conf/extra/xterm-pty.conf" >> /usr/local/apache2/conf/httpd.conf && httpd-foreground'
