Most applications have a build step to download all the dependencies and/or compile your frontend assets.
Usually, it takes most of the deployment time.
Not to mention that the final image may be bigger because of the unnecessary dependencies that were used to download dependencies and compile the frontend assets.
Docker multi-stage builds
One of the easiest ways to make your deployments faster and images slimmer is to use multi-stage docker builds.
Docker caches a specific stage and only re-runs it if any of the dependent files have been changed.
Composer Step
- Use Composer 2.0 image.
- Copy files required for "composer install".
- Run "composer install".
- Copy the rest of the files.
- Run "composer dump-autoload".
#
# PHP Dependencies
#
FROM composer:2.0 as vendor
WORKDIR /app
COPY database/ database/
COPY composer.json composer.json
COPY composer.lock composer.lock
RUN composer install \
--no-interaction \
--no-plugins \
--no-scripts \
--no-dev \
--prefer-dist
COPY . .
RUN composer dump-autoload
NPM Step
- Use NodeJS image.
- Cop files required for the "npm install".
- Run "npm install".
- Copy files required to build your frontend assets.
- Build your frontend assets.
#
# Frontend
#
FROM node:14.9 as frontend
WORKDIR /app
COPY artisan package.json webpack.mix.js yarn.lock tailwind.js ./
RUN npm install
COPY resources/js ./resources/js
COPY resources/sass ./resources/sass
RUN npm run production
Application Step
- Use your desired image.
- Copy built files from the previous stages.
- Enjoy fast deployments.
