This is a Docker image used to serve a Single Page App (pure frontend javascript) using nginx, it support PushState, and includes a way to pass configuration at run time.

This is a fork of SocialEngine/docker-nginx-spa. Changes include:

  • armv7/armv6/amd64 support (not just amd64)
  • Using nginx:alpine-stable as base

Supported tags and Dockerfile links

Included on top of base nginx image

App Setup

This docker image is built for index.html file being in the /app directory. pushState is enabled.

At a minimum, you will want this in your Dockerfile:

FROM ghcr.io/nikeee/docker-nginx-spa:latest

COPY build/ /app
COPY index.html /app/index.html

Then you can build & run your app in the docker container. It will be served by a nginx static server.

$ docker build -t your-app-image .
$ docker run -e API_KEY=yourkey -e API_URL=http://myapi.example.com \
  -e CONFIG_VARS=API_URL,API_KEY -p 8000:80 your-app-image

You can then go to http://docker-ip:8000/ to see it in action.

Env Config

Included is ability to pass run time environmental variables to your app.

This is very useful in case your API is on a different domain, or if you want to configure central error logging.

$ docker run -e RAVEN_DSN=yourkey -e API_URL=http://myapi.example.com  \
  -e CONFIG_VARS=API_URL,RAVEN_DSN -p 8000:80 ghcr.io/nikeee/docker-nginx-spa:latest
 ==> Writing /app/config.js with {"RAVEN_DSN":"yourkey", "API_URL":"http://myapi.example.com"}

This will create a config.js file, which you can then add to your index.html, or load asynchronously. The path can be controlled with CONFIG_FILE_PATH environmental variable.
