Caddy plugin that gives native support for Python WSGI apps.
It embeds the Python interpreter inside Caddy and serves requests directly without going through a reverse proxy or creating a new process.
Go 1.21 and Python 3.12 or later is required, with development files to embed the interpreter.
To install Python3.12 in Ubuntu do:
apt-get install -y software-properties-common
add-apt-repository ppa:deadsnakes/ppa
apt-get install -y python3.12-devTo install in MacOS do:
brew install [email protected]Build this module with caddy at Caddy's official download site. Or:
CGO_ENABLED=1 xcaddy build --with github.com/mliezun/caddy-snakeDockerfile:
FROM python:3.12
WORKDIR /root
RUN apt-get update -y &&\
wget https://go.dev/dl/go1.21.6.linux-amd64.tar.gz &&\
tar -xvf go1.21.6.linux-amd64.tar.gz &&\
rm -rf go1.21.6.linux-amd64.tar.gz &&\
mv go /usr/local &&\
export GOROOT=/usr/local/go &&\
export GOPATH=$HOME/go &&\
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH &&\
go install github.com/caddyserver/xcaddy/cmd/xcaddy@latest
RUN CGO_ENABLED=1 xcaddy build --with github.com/mliezun/caddy-snake
# Use caddy binary located in: /root/caddy{

https_port 9443

}
localhost:9080 {
route {
python "simple_app:main"
}
}
The python rule is an HTTP handler that expects a wsgi app as an argument.
- simple_app. WSGI App that returns the standard hello world message and a UUID.
- example_flask. Flask application that also returns hello workd message and a UUID.
NOTE
At the moment there's no support for virtual environments. To use one is necessary to set the PYTHONPATH env variable when starting caddy. As follows:
PYTHONPATH="venv/lib/python3.12/site-packages/" caddy run --config CaddyfileMake sure to use the right python version depending on your case ^.
