This is a simple nginx image that enables html-5-mode style urls, by redirecting all request to a single file. This use case is typical for single page apps, that are doing all the routing on the client-side.
Configuration is inspired by https://gist.github.com/cjus/b46a243ba610661a7efb .
Furthermore it is able to generate or merge a config.json depending on the environment.
This is image is intended to be used as a base image:
FROM zalari/nginx-html5-env
ENV ENV_PREFIX=ZALARI
ENV CONFIG_NAME=config.json
COPY ./app/dist /usr/share/nginx/html/
COPY config.json /usr/share/nginx/html/
Then all environment variables passed to the container (e.g. via docker run --rm -p 80:80 -e ZALARI_test='true' zalari/nginx-html5-env
having the ZALARI prefix will be used to generate / be merged into /usr/share/nginx/html/config.json and should be available at
http://localhost/config.json.
There is a syntax for accessing nested values; have a look at init/jsonenv.sh for the actual logic for the lack of a better documentation for the time being.
