Recipes

Build a docker image for WriteFreely. This is designed to be run behind a reverse proxy and “patches” the configuration as such.

To build and run:

podman build . --build-arg VERSION=0.16.0 -t writefreely:0.16.0
podman run --rm -it -v ~/volumes/writefreely:/data writefreely:0.16.0
# Follow directions to create initial config.ini and if all goes well, serve up in your preferred style
