⚠️ First, I'd like to invite you to take a look at the official Swoole image: https://hub.docker.com/r/phpswoole/swoole

Dwoole

Docker image for Swoole apps with Composer, auto-restart on development and a production-ready version.

Usage

Requirements

• composer.json
• index.php (this will be your entry-point)

Entry-point file can be overridden with the environment variable ENTRY_POINT_FILE. See this for an example.

Exposed port is 9501

Using Docker Compose?

A docker-compose.yml file would look like:

version: "3"
services:
  web:
    container_name: my_app
    image: leocavalcante/dwoole:dev
    volumes:
      - ./:/app
    ports:
      - "9501:9501"

Yeah! Simple like that.

What is inside?

Options enabled:

• --enable-openssl
• --enable-sockets
• --enable-http2
• --enable-mysqlnd

Development

Comes bundled with:

• sdebug
• Hot-restart
• PDO MySQL & MySQLi
• MongoDB
• Redis

Watch interval can be overridden with the environment variable WATCH_INTERVAL.

Production

Comes bundled with:

• Nothing

It is Swoole only. That is because only you knows what your project really needs. The recommended way to use the production variant is as a base image for you project image.

FROM leocavalcante/dwoole:prod
# Add only what your project really needs
COPY . /app

Then you can add whatever extensions you would like.

Adding PHP extensions

RUN apk add --no-cache freetype-dev libjpeg-turbo-dev libpng-dev libzip-dev \
 && docker-php-ext-configure gd && docker-php-ext-install -j$(nproc) gd zip

Adding PECL extensions

RUN pecl install mongodb \
  && docker-php-ext-enable mongodb

RUN pecl install redis \
  && docker-php-ext-enable redis

You can always take a look at the development Dockerfile to see how it installs extensions that you might have used.

Why not inotify?

• https://github.com/docker/for-win/issues/56

• Linux containers only receive file change events (“inotify events”) if the original files are stored in the Linux filesystem. - https://docs.docker.com/docker-for-windows/wsl/

⚠ Dwoole will always commit to the latest PHP and Swoole versions.
