DEPRECATED - move to 36node/docker-nginx-react

docker-nginx-react

What is this

A docker base image for a Single Page App (eg. React), within nginx server, clear url, push state friendly by default.

We use the minimalist Nginx image based on Alpine linux (~6 MB).

Actually it does nothing with react, no matter the app is made by React or any other framework.

Migrating from 0.2.0

Two environment variables are changed:

• API_GATEWAY => APP_API_GATEWAY
• API_PLACEHOLDER => APP_API_PLACEHOLDER

For all environments start with APP_, it will dynamically subset while server starting. You can put those envrionments in html/js/css files, we will handle it gracefully.

The above two environments are used by nginx, but it may also be interested with development. So we put APP_ prefix on them, make sure you can use them in your code.

Quick start

There are two ways to kick off:

1. Start the default container

note: link your app with this volume -v /your/webapp:/app.

docker run -d --name myapp -p 80:80 -v /your/webapp:/app zzswang/docker-nginx-react

2. Dockfile

notice: we strongly suggest you follow this way

FROM zzswang/docker-nginx-react:latest

ENV DEBUG=off

## Suppose your app is in the dist directory.
COPY ./dist /app

Then just publish your images, and run the container from it.

docker run -d -p 80:80 your_image

Environments

• APP_DIR: the root direactory of your app running in the docker container, usally you do not need to change it.
• APP_PATH_PREFIX: some times you would want to put several sites under one domain, then sub path prefix is required.
• APP_API_PLACEHOLDER: An api call start with a specific path, then the server will redirect the request to APP_API_GATEWAY.
• APP_API_GATEWAY: work together with APP_API_PLACEHOLDER.
• CLIENT_BODY_TIMEOUT: body timeout.
• CLIENT_HEADER_TIMEOUT: header timeout.
• CLIENT_MAX_BODY_SIZE: maximum request body size.
• WHITE_LIST: on or off, turn on white_list feature if on, default off.
• WHITE_LIST_IP: ip you wang put through, set it as (172.17.0.1)|(192.168.0.25).

examples

'use runtime env';

If you want to automatically inject all environment variables start with REACT_APP_ to an HTML file during container startup，you can add one line 'use runtime env'; to your index.html

<script>
  (function initRuntimeConfig() {
    'use runtime env';
  })();
</script>

and the code block in index.html file will be replaced to

<script>
  (function initRuntimeConfig() {
    'use runtime env';
window._36node=window._36node||{};
window._36node["REACT_APP_VAR2"]="var2";
window._36node["REACT_APP_VAR1"]="var1";
  })();
</script>

APP_API_PLACEHOLDER && APP_API_GATEWAY

note: we suggest you call api with a full url with domain, make your api server independently. But we need to take care of cross domain and https issues.

If your app calls api without domain, and not deploy behind a Well Structured haproxy(or other forward proxy), you can turn on this option.

APP_API_PLACEHOLDER="/api/v1"
APP_API_GATEWAY="http://api.your.domain"

Then all url match /api/v1 will redirect to http://api.your.domain. Please notice that the /api/v1 is stripped.

APP_PATH_PREFIX

Suppose you have a domain

www.books.com

You have two apps Computer and Math, want put them under the same domain.

http://www.books.com/computer
http://www.books.com/math

For App computer, setting

APP_PATH_PREFIX=/computer

You also need to take care about this path prefix in your APP. Like react router(3.x), it could take a prefix option. We strongly suggest to use the same envrionment in your source code. So this image will take care of it for you. For example, in your router.js file:

import useBasename from "history/lib/useBasename";
import { browserHistory } from "react-router";

export const myHistory = useBasename(() => browserHistory)({
  basename: `/${APP_PATH_PREFIX}`
});
