SPA+Docker example

This is an SPA+Docker example.

If you want to launch this example, type the following command and open http://localhost.

$ docker-compose up

It executes the following steps.

1. Build a docker image whose definition is written in Dockerfile.
   • Since Dockerfile has multi stage build, this example requires Docker >= 17.05.
   • Multi stage build in this case is comprised of:
     1. Build SPA with webpack.
     2. Bundle it in a nginx:alpine. This image is quite smaller than single stage build.
2. Run the image built above. The bootstrap script is serve.sh.
   1. Generate env.js having environment variables defined in docker-compose.yml. This will be loaded in SPA.
   2. Generate nginx.conf nginx uses.
   3. Start nginx with no daemon options.
