This repo holds the Dockerfile used to create the base image available at Docker hub for building Ur/web apps.
You can use it in your own Dockerfiles by extending the base image, like this:
FROM destynova/urweb:20190907
ADD src /app/src
ADD css /app/css
WORKDIR /app/src
RUN urweb appname -dbms sqlite -db db.sqlite -output /app/appname.exe
For an example of how to do this to build and deploy an Ur/web app on Heroku, check out memvalid, which includes a tiny heroku.yml
file that controls the build/deploy steps.
