      Kubernetes Starter Kit for Development Teams: Becoming Productive From Day 1


      About the Talk

      When rolling out new features for your business, it’s important to have a development cycle that can keep up with rapid iterations and changes. Go beyond setting up Kubernetes clusters to creating a faster development cycle that increases business efficiency, provides comprehensive observability, and enables faster recovery with troubleshooting techniques.

      Whether you’re just getting started or are an active user of Kubernetes, this deployment starter kit will help you become productive from day one and focus on your business logic.

      What You’ll Learn

      • How to get the best out of your Kubernetes investment while simplifying operations and controlling costs.
      • Why it’s worthwhile to build your own custom repeatable stack for specific day-2 operations.
      • What to consider when building your own Kubernetes starter kit — finding reliable, cloud-agnostic products and tools with predictable costs — for containerization, monitoring, logging, backup, ingress, advanced observability, GitOps, and progressive release.

      How To Create PHP Development Environments with Docker Compose: A DigitalOcean Workshop Kit

      How to Create PHP Development Environments with Docker Compose Workshop Kit Materials

      This workshop kit is designed to help a technical audience become familiar with Docker Compose and learn to set up a working development environment for a Laravel application using containers.

      The aim is to provide a complete set of resources for a speaker to host an event and deliver an introductory talk on Docker Compose in the context of PHP development environments. It includes:

      • Slides and speaker notes including commands for running an optional live demo. This talk runs for roughly 40 minutes.
      • A GitHub repository containing the demo app code and the additional files necessary to get a PHP development environment up and running with Docker and Docker Compose.
      • This tutorial, which walks a user through getting the Travellist demo Laravel application running on containers with Docker Compose.

      This guide is intended to supplement the talk demo with additional detail and elucidation.


      This tutorial, designed to accompany the slides and speaker notes for the How To Create PHP Development Environments with Docker Compose Slide Deck, will show you how to get a demo Laravel application up and running with Docker and Docker Compose, using the setup that we discuss in greater detail in our guide on How To Set Up Laravel with Docker Compose on Ubuntu 20.04.

      Note: This material is intended to demonstrate how to use Docker Compose to create PHP development environments. Although our demo consists of a Laravel application running on a LEMP server, readers are encouraged to modify and adapt the included setup to suit their own needs.


      To follow this tutorial, you will need:

      Step 1 — Download the Demo Application

      To get started, download release tutorial-4.0.3 of the Travellist Laravel Demo application, which contains the application files and the Docker Compose setup that are used in this workshop kit.

      • curl -L --output

      Next, install the unzip utility in case that is not yet installed on your local machine or development server:

      Unzip the package and move into the newly created directory:

      • unzip
      • cd travellist-laravel-demo-tutorial-4.0.3

      Now, you can run an ls command to inspect the contents of the cloned repository:

      • ls -l --group-directories-first

      You’ll receive output like this:

      -rw-rw-r-- 1 sammy sammy 181665 mei 14 16:16 composer.lock
      -rw-rw-r-- 1 sammy sammy   1016 mei 14 16:16 docker-compose.yml
      -rw-rw-r-- 1 sammy sammy    737 mei 14 16:16 Dockerfile
      -rw-rw-r-- 1 sammy sammy   1013 mei 14 16:16 package.json
      -rw-rw-r-- 1 sammy sammy   1405 mei 14 16:16 phpunit.xml
      -rw-rw-r-- 1 sammy sammy    814 mei 14 16:16
      -rw-rw-r-- 1 sammy sammy    563 mei 14 16:16 server.php
      -rw-rw-r-- 1 sammy sammy    538 mei 14 16:16 webpack.mix.js

      Here are the relevant directories and files for the Docker Compose setup we’re using:

      • docker-compose/ — contains files used to set up the containerized environment, such as the Nginx configuration file and the application’s MySQL dump.
      • docker-compose.yml — here, we define all services we’ll need: app, web, and db. Shared volumes and networks are also set up here.
      • Dockerfile — this defines a custom application image based on php-fpm. While the web and db services are based on default images, the app service requires additional setup steps, that’s why we are creating a custom image for this service container.

      All remaining files are part of the application.

      Step 2 — Set Up the Application’s .env File

      You’ll now create a new .env file using the included .env.example file as base. Because Laravel uses a dot env file that is also supported by Docker Compose, the values set here will be available at build time when you bring your environment up, and will be used to set up the database service container.

      For reference, this is what the included .env file looks like. Because these settings are being applied to an isolated development environment, there is no need to change database credentials in this file, but you are free to do so if you would like.



      Once you are satisfied with your .env file, you should move onto running Docker Compose, as outlined in the next session.

      Step 3 — Run Docker Compose

      Once you have your .env file in place, you can bring your environment up with:

      This will execute Docker Compose in detached mode, which means it will run in the background. This command may take a few moments to run when you execute it for the first time, since it will download and build the app service image.


      Creating network "travellist-laravel-demo-tutorial-403_travellist" with driver "bridge" Creating travellist-db ... done Creating travellist-app ... done Creating travellist-nginx ... done

      To verify the status of your services, you can run:

      You’ll receive output like this:


      Name Command State Ports -------------------------------------------------------------------------------- travellist-app docker-php-entrypoint php-fpm Up 9000/tcp travellist-db mysqld Up 3306/tcp, 33060/tcp travellist-nginx / ngin ... Up>80/tcp

      Your containerized PHP development environment is up and running, but there are still a couple steps required so that you can access the application from your browser. We’ll set everything up in the next and final step.

      Step 4 — Finish Setting Up the Application

      Now that you have a development environment able to handle PHP scripts, you can install the application dependencies using composer. To execute commands inside containers, you can use the docker-compose exec command, followed by the name of the service container and the command you want to execute.

      The following command will run composer install on the app service container, where PHP is installed:

      • docker-compose exec app composer install

      After the dependencies are installed, you’ll need to generate a unique application key using the artisan Laravel command line tool:

      • docker-compose exec app php artisan key:generate


      Application key set successfully.

      You can now access the demo application by pointing your browser to localhost if you are running this setup on a local machine, or your remote server’s domain name or IP address if you are running this on a development server. The server expects connections on port 8000, so be sure to include :8000 in the address:


      You will see a page like this:

      Laravel Travellist Demo

      With this page displaying on your browser you have successfully set up your application.

      Docker Compose Quick Reference

      In this section, you’ll find a brief reference of the main Docker Compose commands used to manage a containerized environment. These should be executed from the same directory where you have set up your docker-compose.yml file.


      Builds any custom images associated with the current docker-compose.yml file, without bringing the environment up.


      Brings the environment up. Custom images will be automatically built when not cached, and when you make changes to the referenced Dockerfile.


      Similar to docker ps, shows the status of active services associated with the current docker-compose.yml file.


      Executes a command on the specified service.

      • docker-compose exec service-name command


      Stops the active environment, while keeping any allocated resources: containers, volumes, and networks.


      Brings up an environment that was previously stopped with the stop command.


      Shows latest logs from active services.


      Shows processes running on the specified service.

      docker-compose top service-name


      Brings the containerized environment down along with any allocated resources.

      docker-compose down

      For more information about each available Docker Compose command, please refer to their official documentation.


      This guide complements the How To Create PHP Development Environments with Docker Compose Workshop Kit’s slides and speaker notes, and is accompanied by a demo GitHub repository containing all necessary files to follow up with the demo component of this workshop.
