Webpack-encore: How to use webpack-encore in docker container?

[powerlimit]

Hi @powerlimit,

Could you detail a bit more what you are trying to achieve and the issue(s) you are having?

As far as I know any container with Node.js + Yarn/npm should work fine with Encore.

COPY docker-entrypoint.sh /usr/local/bin

ENTRYPOINT `["/usr/local/bin/docker-entrypoint.sh"]``

here is my dockerfile

``#!/bin/bash
if [ ! -f /public/build/manifest.json ]; then
yarn install
fi

exec "yarn run encore dev --watch"``

and here is entrypoint.

it does not work.

after creating container i want encore to watch changes in scss and js files. can you help?

Put a docker-compose.yaml file in the root of your project containing:

version: "3"

services:
    app:
        image: php:7.2-alpine
        volumes:
            - .:/app
        ports:
            - "${APP_PORT:-8000}:8000"
        working_dir: /app
        command: ["bin/console", "server:run", "0.0.0.0"]

    encore:
        image: node:10-alpine
        volumes:
            - .:/app
        ports:
            - "${DEV_SERVER_PORT:-8080}:8080"
        working_dir: /app
        command: ["yarn", "dev-server", "--host=0.0.0.0"]

To start your Symfony app + Encore dev server:

docker-compose up

To stop your Symfony app + Encore dev server:

docker-compose down

To build your assets for production:

docker-compose run --rm encore yarn build

maybe this is the problem:
https://symfony.com/doc/current/frontend/encore/virtual-machine.html#file-watching-issues

btw:

#!/bin/bash
if [ ! -f /public/build/manifest.json ]; then
yarn install
fi

this runs yarn install even when everything is installed but not yet build with webpack. But when yarn has installed, it returns rather quickly. So just skip the if
