“ Docker allows you to package an application with all
of its dependencies into a standardized unit for software development.

Image Building Introducing the Dockerfile
(Simplified) Dockerfile for PHP FROM ubuntu:17.04 RUN apt install -y
php-cli COPY hello.php /code WORKDIR /code ENTRYPOINT [“php”] CMD [“-v”]
(Simplified) Dockerfile for PHP FROM ubuntu:17.04 RUN apt install -y
php-cli COPY hello.php /code WORKDIR /code ENTRYPOINT [“php”] CMD [“-v”]
(Simplified) Dockerfile for PHP FROM ubuntu:17.04 RUN apt install -y

Tips I’ve learnt the hard way, so you don’t have
to
Tips: Use Random Ports services: php: ports: - 80
Tips: Mindful of Network Collisions Every new docker-compose file is,
potentially, a new docker network / bridge on your host. Eventually, you’ll get a collision docker-compose down
Tips: Prune docker system prune Docker CE >= 17.04
Tips: env_file Lots of environment variables defined inside compose.yml? Duplication?
env_file: - some file
Tips: Alpine Linux Unless you need Ubuntu / Fedora, use
Alpine Linux Ubuntu -- 130MB Alpine -- 3.99MB
Tips: Keep a Single Dockerfile Using MultiStage Builds, you can
usually keep your project to a single Dockerfile FROM node AS node RUN npm install FROM php COPY --from=node assets
Tips: Don’t Bust Your Build Cache COPY composer.json /code RUN
composer install COPY . /code
Tips: Logging ALWAYS LOG to STDOUT
Production Tip Mandatory Requirement --read-only
