Collection of Dockerfile and docker-compose configurations wrapped in an easy-to-use command line, oriented for PHP projects.

What is Docker Starter Kit

This repository provides a Docker infrastructure for your PHP projects with built-in support for HTTPS, custom domain, databases, workers... and is used as a foundation for our projects at JoliCode.

Warning

You are reading the README of version 4 that uses castor.

• If you are using Invoke, you can read the dedicated README;
• If you are using Fabric, you can read the dedicated README;

Project configuration

Before executing any command, you need to configure a few parameters in the castor.php file, in the create_default_variables() function:

• project_name (required): This will be used to prefix all docker objects (network, images, containers);

• root_domain (optional, default: project_name + '.test'): This is the root domain where the application will be available;

• extra_domains (optional): This contains extra domains where the application will be available;

• php_version (optional, default: 8.3): This is PHP version.

For example:

function create_default_variables(): array
{
    $projectName = 'app';
    $tld = 'test';

    return [
        'project_name' => $projectName,
        'root_domain' => "{$projectName}.{$tld}",
        'extra_domains' => [
            "www.{$projectName}.{$tld}",
            "admin.{$projectName}.{$tld}",
            "api.{$projectName}.{$tld}",
        ],
        'php_version' => 8.3,
    ];
)

Will give you https://app.test, https://www.app.test, https://api.app.test and https://admin.app.test pointing at your application/ directory.

Note

Some castor tasks have been added for DX purposes. Checkout and adapt the tasks install, migrate and cache_clear to your project.

Usage documentation

We provide a README.dist.md to bootstrap your project documentation, with everything you need to know to start and interact with the infrastructure.

If you want to install a Symfony project, you can run (before castor init):

castor symfony [--web-app]

To replace this README with the dist, and remove all unnecessary files, you can run:

castor init

Note

This command can be run only once

Also, in order to improve your usage of castor scripts, you can install console autocompletion script.

If you are using bash:

castor completion | sudo tee /etc/bash_completion.d/castor

If you are using something else, please refer to your shell documentation. You may need to use castor completion > /to/somewhere.

Castor supports completion for bash, zsh & fish shells.

Cookbooks

How to install third party tools with Composer

Read the cookbook

If you want to install some third party tools with Composer, it is recommended to install them in their dedicated directory. PHPStan and PHP-CS-Fixer are already installed in the tools directory.

We suggest to:

1. create a composer.json which requires only this tool in tools/<tool name>/composer.json;

2. create an executable symbolic link to the tool from the root directory of the project: ln -s ../<tool name>/vendor/bin/<tool bin> tools/bin/<tool bin>;

[!NOTE] Relative symlinks works here, because the first part of the command is relative to the second part, not to the current directory.

Since tools/bin path is appended to the $PATH, tools will be available globally in the builder container.

How to change the layout of the project

Read the cookbook

If you want to rename the application directory, or even move its content to the root directory, you have to edit each reference to it. Theses references represent each application entry point, whether it be over HTTP or CLI. Usually, there is three places where you need to do it:

• In Nginx configuration file: infrastructure/docker/services/php/frontend/etc/nginx/nginx.conf. You need to update http.server.root option to the new path. For example:

  - root /var/www/application/public;
  + root /var/www/public;

• In all workers configuration file: infrastructure/docker/docker-compose.worker.yml:

  - command: php -d memory_limit=1G /var/www/application/bin/console messenger:consume async --memory-limit=128M
  + command: php -d memory_limit=1G /var/www/bin/console messenger:consume async --memory-limit=128M

• In the builder, to land in the right directory directly: infrastructure/docker/services/php/Dockerfile:

  - WORKDIR /var/www/application
  + WORKDIR /var/www

How to use with Webpack Encore

Read the cookbook

[!NOTE] this cookbook documents the integration of webpack 5+. For older version of webpack, use previous version of the docker starter.

If you want to use Webpack Encore in a Symfony project,

1. Follow instructions on symfony.com to install webpack encore.

   You will need to follow these instructions too.

2. Create a new service for encore:

   Add the following content to the docker-compose.yml file:

   services:
       encore:
           build:
               context: services/php
               target: builder
           volumes:
               - "../..:/var/www:cached"
           command: "yarn run dev-server --hot --host 0.0.0.0 --allowed-hosts encore.${PROJECT_ROOT_DOMAIN} --allowed-hosts ${PROJECT_ROOT_DOMAIN} --client-web-socket-url-hostname encore.${PROJECT_ROOT_DOMAIN} --client-web-socket-url-port 443 --client-web-socket-url-protocol wss"
           labels:
               - "traefik.enable=true"
               - "project-name=${PROJECT_NAME}"
               - "traefik.http.routers.${PROJECT_NAME}-encore.rule=Host(`encore.${PROJECT_ROOT_DOMAIN}`)"
               - "traefik.http.routers.${PROJECT_NAME}-encore.tls=true"
               - "traefik.http.services.encore.loadbalancer.server.port=8080"
           profiles:
               - default

3. Update the webpack configuration to specify the asset location in dev:

   diff --git a/application/webpack.config.js b/application/webpack.config.js
   index 056b04a..766c590 100644
   --- a/application/webpack.config.js
   +++ b/application/webpack.config.js
   @@ -6,13 +6,22 @@ if (!Encore.isRuntimeEnvironmentConfigured()) {
       Encore.configureRuntimeEnvironment(process.env.NODE_ENV || 'dev');
   }
   
   +
   +if (Encore.isProduction()) {
   +    Encore
   +        // public path used by the web server to access the output path
   +        .setPublicPath('/build')
   +        // only needed for CDN's or sub-directory deploy
   +        //.setManifestKeyPrefix('build/')
   +} else {
   +    Encore
   +        .setPublicPath('https://encore.app.test/build')
   +        .setManifestKeyPrefix('build/')
   +}
   +
   Encore
       // directory where compiled assets will be stored
       .setOutputPath('public/build/')
   -    // public path used by the web server to access the output path
   -    .setPublicPath('/build')
   -    // only needed for CDN's or sub-directory deploy
   -    //.setManifestKeyPrefix('build/')
   
       /*
       * ENTRY CONFIG

If the assets are not reachable, you may accept self-signed certificate. To do so, open a new tab at https://encore.app.test and click on accept.

Add the following file infrastructure/docker/services/redirectionio-agent/Dockerfile:

FROM alpine:3.12 AS alpine

WORKDIR /tmp

RUN apk add --no-cache wget ca-certificates \
    && wget https://packages.redirection.io/dist/stable/2/any/redirectionio-agent-latest_any_amd64.tar.gz \
    && tar -xzvf redirectionio-agent-latest_any_amd64.tar.gz

FROM scratch

# Binary copied from tar
COPY --from=alpine /tmp/redirection-agent/redirectionio-agent /usr/local/bin/redirectionio-agent

# Configuration, can be replaced by your own
COPY etc /etc

# Root SSL Certificates, needed as we do HTTPS requests to our service
COPY --from=alpine /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/

CMD ["/usr/local/bin/redirectionio-agent"]

Add infrastructure/docker/services/redirectionio-agent/etc/redirectionio/agent.yml:

instance_name: "my-instance-dev" ### You may want to change this
listen: 0.0.0.0:10301

Then you'll need wget. In infrastructure/docker/services/php/Dockerfile, in stage frontend:

RUN apt-get update \
    && apt-get install -y --no-install-recommends \
        wget \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /usr/share/doc/*

You can group this command with another one.

Then, after installing nginx, you need to install the module:

RUN wget -q -O - https://packages.redirection.io/gpg.key | gpg --dearmor > /usr/share/keyrings/redirection.io.gpg \
    && echo "deb [signed-by=/usr/share/keyrings/redirection.io.gpg] https://packages.redirection.io/deb/stable/2 focal main" | tee -a /etc/apt/sources.list.d/packages_redirection_io_deb.list \
    && apt-get update \
    && apt-get install libnginx-mod-redirectionio \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /usr/share/doc/*

Finally, you need to edit infrastructure/docker/services/php/frontend/etc/nginx/nginx.conf to add the following configuration in the server block:

redirectionio_pass redirectionio-agent:10301;
redirectionio_project_key "AAAAAAAAAAAAAAAA:BBBBBBBBBBBBBBBB";

Don't forget to change the project key.

            BLACKFIRE_SERVER_TOKEN: FIXME
            BLACKFIRE_CLIENT_ID: FIXME
            BLACKFIRE_CLIENT_TOKEN: FIXME
        profiles:
            - default

Then you'll need wget. In infrastructure/docker/services/php/Dockerfile, in stage base:

RUN apt-get update \
    && apt-get install -y --no-install-recommends \
        wget \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /usr/share/doc/*

You can group this command with another one.

Then, after installing PHP, you need to install the probe:

RUN wget -q -O - https://packages.blackfire.io/gpg.key | gpg --dearmor > /usr/share/keyrings/blackfire.io.gpg \
    && sh -c 'echo "deb [signed-by=/usr/share/keyrings/blackfire.io.gpg] http://packages.blackfire.io/debian any main" > /etc/apt/sources.list.d/blackfire.list' \
    && apt-get update \
    && apt-get install -y --no-install-recommends \
        blackfire-php \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /usr/share/doc/* \
    && sed -i 's#blackfire.agent_socket.*#blackfire.agent_socket=tcp://blackfire:8707#' /etc/php/${PHP_VERSION}/mods-available/blackfire.ini

If you want to profile HTTP calls, you need to enable the probe with PHP-FPM. So in infrastructure/docker/services/php/Dockerfile:

RUN phpenmod blackfire

Here also, You can group this command with another one.

How to add support for crons?

Read the cookbook

In order to set up crontab, you should add a new container:

# services/php/Dockerfile

FROM php-base AS cron

RUN apt-get update \
    && apt-get install -y --no-install-recommends \
        cron \
    && apt-get clean \

COPY crontab /etc/cron.d/crontab
RUN crontab /etc/cron.d/crontab

CMD ["cron", "-f"]

And you can add all your crons in the services/php/crontab file:

* * * * * su app -c "/usr/local/bin/php -r 'echo time().PHP_EOL;'" > /proc/1/fd/1 2>&1

Finally, add the following content to the docker-compose.yml file:

services:
    cron:
        build:
            context: services/php
            target: cron

        <<: *worker_base
        command: /var/www/application/my-worker

    worker_date:
        <<: *worker_base
        command: watch -n 1 date

How to use PHP FPM status page?

Read the cookbook

If you want to use the PHP FPM status page you need to remove a configuration block in the infrastructure/docker/services/php/frontend/etc/nginx/nginx.conf file:

-        # Remove this block if you want to access to PHP FPM monitoring
-        # dashboarsh (on URL: /php-fpm-status). WARNING: on production, you must
-        # secure this page (by user IP address, with a password, for example)
-        location ~ ^/php-fpm-status$ {
-            deny all;
-        }
-

And if your application uses the front controller pattern, and you want to see the real request URI, you also need to uncomment the following configuration block:

-            # # Uncomment if you want to use /php-fpm-status endpoint **with**
-            # # real request URI. It may have some side effects, that's why it's
-            # # commented by default
-            # fastcgi_param SCRIPT_NAME $request_uri;
+            # Uncomment if you want to use /php-fpm-status endpoint **with**
+            # real request URI. It may have some side effects, that's why it's
+            # commented by default
+            fastcgi_param SCRIPT_NAME $request_uri;

RUN apt-get update \
    && apt-get install -y --no-install-recommends \
        pg-activity \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /usr/share/doc/*

Then, you can add the following content to the castor.php file:

#[AsTask(description: 'Monitor PostgreSQL', namespace: 'app:db')]
function pg_activity(): void
{
    docker_compose('exec postgres pg_activity -U app');
}

Finally you can use the following command:

castor app:db:pg-activity

How to use MySQL instead of PostgreSQL

Docker For Windows support

Read the cookbook

This starter kit is compatible with Docker for Windows, so you can enjoy native Docker experience on Windows. You will have to keep in mind some differences:

• You will be prompted to run the env vars manually if you use PowerShell.

How to access a container via hostname from another container

Read the cookbook

Let's say you have a container (frontend) that responds to many hostnames: app.test, api.app.test, admin.app.test. And you have another container (builder) that needs to call the frontend with a specific hostname - or with HTTPS. This is usually the case when you have a functional test suite.

To enable this feature, you need to add extra_hosts to the builder container like so:

services:
    builder:
        # [...]
        extra_hosts:
            - "app.test:host-gateway"
            - "api.app.test:host-gateway"
            - "admin.app.test:host-gateway"

How to connect networks of two projects

Read the cookbook

Let's say you have two projects foo and bar. You want to run both projects a the same time. And containers from foo project should be able to dialog with bar project via public network (host network).

In the foo project, you'll need to declare the bar_default network in docker-compose.yml:

networks:
    bar_default:
        external: true

Then, attach it to the the foo router:

services:
    router:
        networks:
            - default
            - bar_default

Finally, you must remove the constraints on the router so it'll be able to discover containers from another docker compose project:

--- a/infrastructure/docker/services/router/traefik/traefik.yaml
+++ b/infrastructure/docker/services/router/traefik/traefik.yaml
 providers:
   docker:
     exposedByDefault: false
-    constraints: "Label(`project-name`,`{{ PROJECT_NAME }}`)"
   file:

Finally, you must :

1. build the project foo
2. build the project bar
3. Create the network bar_default (first time only)

   docker network create bar_default
   

4. start the project foo
5. start the project bar
