docker compose setup for local development

This development environment uses as much default docker containers as possible.

Default nginx container - Nginx container with brotli support
Default mariadb container - serves the database
Default mailhog container - catches all outgoing mail and displays it
Default docker-hoster container - makes the containers accessible by name
Default busybox container - used for initialization
Default blackfire container - used for profiling your site
Default ngrok container - used to share your local site with the world
Default dozzle container - used to inspect the logs in browser
Slightly changed php container (added graphicsmagick, rsync and some php modules) - serves up php

Disclaimer: This was developed and tested on Linux. OSX has some limitations when it comes to easy access to docker hosts by hostname: Docker Known limitations, use cases, and workarounds

Pull requests are welcome ;-)

Installation

mkdir project && cd project
git clone https://github.com/Tuurlijk/docker-local.git .docker
ln -s .docker/.env .env

Make sure the containers can read and write your files

The different container processes run under different user ids. The containers must be able to read, and some must be able to write host files mounted as volumes inside the container. The default user and group id's the processes are set to run as are 1000 and 1000. If your uid and gid are not 1000, set the UID and GID env vars in the .env file.

You can see your uid and gid by doing id -u and id -g.

Set the project name in .env

Set up a project name in the .env file.

# Project name
COMPOSE_PROJECT_NAME=my_great_project

Start the environment

Adjust other env vars if needed. When you are done, you can start the environment with:

docker-compose -f .docker/docker-compose.yml up

For ease of use you can create an alias:

alias dc="docker-compose -f .docker/docker-compose.yml"

The service user

The services in the web and php* containers run under user docker. If you want to log in to the php container as that user you can do:

dev exec -u docker php /bin/bash

# If you are logging is as your host user, you can do:
dev exec -u $UID php /bin/bash

# Or even leave out the user part all together:
dev exec php /bin/bash

You can create an alias, so you don't have to type the user out all the time.

alias de="dev -u $UID exec"

Aliases

Bonus aliases:

# Colorful messages
e_header()  { echo -e "\n\033[1m$@\033[0m"; }
e_success() { echo -e " \033[1;32m✔\033[0m  $@"; }
e_error()   { echo -e " \033[1;31m✖\033[0m  $@"; }

# Docker
alias d=docker
alias dp="docker ps"
alias dc="docker-compose -f .docker/docker-compose.yml"
alias dev="docker-compose -f .docker/docker-compose.yml"
alias down='f(){ dev rm -fsv $@; unset -f f; }; f'
alias up='f(){ dev up -d $@ && dev logs -f before_script after_script; unset -f f; }; f'
alias on=up
alias off=down
alias re='f(){ dev rm -fsv $@ && dev build $@ && dev up -d $@ && dev logs -f before_script after_script; unset -f f; }; f'
alias offon=re
alias ds="dev exec php bash -l"
alias de="dev exec"
alias cf='e_header "Running typo3cms cache:flush"; ds -c "./public/bin/typo3cms cache:flush"; e_success Done'
alias ct='e_header "Clearing ./public/typo3temp/*"; ds -c "echo removing \`find ./public/typo3temp/ -type f | wc -l\` files; rm -rf ./public/typo3temp/*"; e_success Done'

SSL support

To generate the certificates and make the system trust them, we use the fantastic mkcert tool.

The provided certificate has wildcards for:

*.dev.local
*.blackfire.local
*.black.local
*.fire.local
*.bf.local
*.xdebug.local
*.debug.local
*.xdbg.local
*.mail.local
*.logs.local

The certificate was generated from the web/ssl folder using:

mkcert -cert-file public.crt -key-file private.rsa "dev.local" "*.dev.local" "*.xdebug.local" "*.xdbg.local" "*.blackfire.local" "*.bf.local" "*.black.local" "*.fire.local" "*.debug.local" "*.mail.local" "*.mailhog.local" "*.logs.local"

Configuration

Each container may use configuration files from the .docker folder.

The environment file /.env defines some important variables. Check yout platform documentation so you know what version of PHP and Mariadb you need. For TYPO3 you can find the requirements here: https://get.typo3.org/version

COMPOSE_PROJECT_NAME

The project name is used in the domain names of the http containers:

prefix.dev.local - default PHP
prefix.xdebug.local / prefix.debug.local / prefix.xdbg.local - Xdebug enabled PHP
prefix.blackfire.local / prefix.bf.local / prefix.fire.local / prefix.black.local - Blackfire enabled PHP
prefix.mail.local - Mailhog
prefix.logs.local - Dozzle

All environments are started within their own subnet. They can reach each other by the service name or container_name specified in .docker/docker-compose.yml. So the php machine can reference the redis machine by using hostname redis or container_name: ${COMPOSE_PROJECT_NAME}_web. So if your project name is babel the php machine can reach the redis machine by using babel_redis as hostname.

PHP versions

There are different PHP versions available. The default is PHP 7.4

PHP_VERSION

One of: 5.6, 7.1, 7.2, 7.3, 7.4, 8.0, 8.1

Database version

One of the mariadb versions. The default is 10.2

DATABASE_VERSION

One of teh tags on https://hub.docker.com/_/mariadb

mysql database credentials

MYSQL_DATABASE

The name of the database that mysql will import the dump into

MYSQL_USER

The name of the mysql user

MYSQL_PASSWORD

The password of the mysql user

MYSQL_ROOT_PASSWORD

The password of the mysql root user

Ngrok

Expose a local web server to the internet. Share your local development environment with others

NGROK_AUTH

Your token from https://dashboard.ngrok.com/auth

This option is commented out by default because you are better of setting it globally in your shell environment.

NGROK_PORT=prefix.dev.local:443

Hostname and port of the exposed website

NGROK_USERNAME

Username for htaccess based authentication of the exposed website

NGROK_PASSWORD

Password for htaccess based authentication of the exposed website

Blackfire credentials

Use blackfire to profile your PHP code. Get the credentials from https://blackfire.io/my/settings/credentials

BLACKFIRE_CLIENT_ID

Client id

This option is commented out by default because you are better of setting it globally in your shell environment.

BLACKFIRE_CLIENT_TOKEN

Client token

This option is commented out by default because you are better of setting it globally in your shell environment.

BLACKFIRE_SERVER_ID

Server id

This option is commented out by default because you are better of setting it globally in your shell environment.

BLACKFIRE_SERVER_TOKEN

Server token

This option is commented out by default because you are better of setting it globally in your shell environment.

HOSTMAP_IMAGE

By default the dvdarias/docker-hoster image is started. This may give trouble if you start multiple environments. Docker-hoster does not seem to cope too well. An alternative is to start a standalone image that does docker dns like kevinjqiu/resolvable.

If you opt for that, you can set HOSTMAP_IMAGE to bash.

Example resolvable config:

version: "3"
services:
  resolvable:
    image: kevinjqiu/resolvable
    restart: always
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro
      - /etc/resolv.conf:/tmp/resolv.conf

TEMPLATE

Use a template to get an installation up quickly. Each template has a before.sh file to set up the environment before any machine starts and an after.sh file to set up the environment after the machines have started. This may fix permissions and copy over files like composer.json and AdditionalConfiguration.php.

Please keep in mind that you may need to tweak the MariaDb and PHP versions for the older TYPO3 versions.

Choose from:

empty
default
TYPO3-v7
TYPO3-v8
TYPO3-v9
TYPO3-v10
TYPO3-v11
Neos-v4

Add your own templates in .docker/template/

Scripts

There are a few helper scripts in .docker/bin. Most of these are meant to be executed from the project root (where the .env file is stored).

Dumping a database

There is a script in .docker/bin/ called dump.sh. It uses the database credentials defined in the .env file to dump the database from the database host. You can execute it by doing:

./.docker/bin/dump.sh

The database dump will be stored in .docker/db/dump.

Importing a database

There is a script in .docker/bin/ called import.sh. It uses the database credentials defined in the .env file to import a database to the database host. You can execute it by doing:

./.docker/bin/import.sh dumpfile.sql.gz

Automatically importing a database

Any files in .docker/db/import ending in tar.gz, sql or gz will be imported. This can be of use to you if you wish to execute SQL on each run of the db container. Also nice if you want to run a databbase in ram, because then you will need to re-import the data on each run of the container.

Run database in ram

The database in the container is already pretty fast if you have a ssd, But if you want more speed, you can run it in ram.

The database can run in a tmpfs volume. If you want to save it, please use ./.docker/bin/dump.sh. This will create a gzipped dump in .docker/db/dump.

If you want to run the db in ram, uncomment the dbData volume lines at the end of docker-compose.override.yml:

#volumes:
#  dbData:
#    driver_opts:
#      type: tmpfs
#      device: tmpfs
#      o: "noatime,noexec,nodiratime,nodev,nosuid,async,mode=0770,uid=${UID:-1000},gid=${GID:-1000}"

Ephemeral

The containers are ephemeral as suggested in Best practices for writing Docker files

The image defined by your Dockerfile should generate containers that are as ephemeral as possible. By “ephemeral”, we mean that the container can be stopped and destroyed, then rebuilt and replaced with an absolute minimum set up and configuration.

Of course all the files in your project directory remain in place, but temporary stuff like public/typo3temp and var run in ramdisk (tmpfs) volumes that will be removed when the machines stop.

PHPStorm Xdebug

In docker-compose.yml an environment variable is set: PHP_IDE_CONFIG=serverName=${COMPOSE_PROJECT_NAME}. Make sure that you have this server configured in PHPStorm. The name of the server must be the value of your COMPOSE_PROJECT_NAME.

Known Issues

Sometimes the var and Web directories get created with owner and group root. This breaks the installation.
Mariadb fails to set the configured charset on first image start. This may be a problem of the stock MariaDb docker image.
