README

⚠ For Magento 2.3, see the 2.x branch.

Docker for services, php locally. No sync, no mental overhead, no performance penalties.
php, nginx, https, http/2, varnish, mysql elasticsearch, rabbitmq, mailhog

Reasoning

Docker is easy, docker scales, we love Docker, but docker's volume mounting is slow, we can't have slow.

The problem with all the docker devboxes is that they require running php inside a vm. The problem with php in a VM is that files need to be available in the VM, but it also needs to have files outside the VM, because programs like PHPStorm and others do not accept network drives.

Sync is slower than no sync. docker-sync, unison, mutagen offer good sync solutions, but always slower than no sync.

Hovever, syncs require additional HDD space and additional mental overhead: Are my files synced?, Is my sync broken? Are there sync conflicts? Why did that file appear here? Where should I execute my php cli scripts? Where should I run node cli? Why is my system slow? Sync is bad.

Goals

• It should be possible for a frontend developer without any backend skillsto set up a development environment.
• It should be possible for a backend developer to add or upgrade services.
• It should be possible for a backend developer to propagate the changes to the rest of the team with version control.

Principles

• No magic: As few CLI tools that will automatically 'fix' things. Do not use wrappers around existing tools: docker / etc. Exception: php runs locally, needs to be set up.
• Declarative: Developer should define the final state instead of running upgrade scripts (hence, docker).
• Minimal: Use as few cpu cycles and memory as possible.

Requirements

• Recent OSX

Global installation (only once)

Cleanup your system

Since we're running some things locally it probably is a good time to clean some stuff up.

• Run brew doctor and make sure you don't have errors.
• Run brew update to update to the latest version.

You should not have any services running like.

• php: find them with brew list | grep php, uninstall them using brew uninstall —f <packages>. With the force flag you'll delete all installed versions of formula.
• httpd: Disable apache that is OSX native. http://localhost/ should not return anything.
• mysql: uninstall or disable mysql, or at least make sure it doesnt run on the default MySQL port.
• nginx: uninstall

Take a look at ~/.bash_profile or ~/.zshrc and make sure it doesn't contain any references to $BREW_PREFIX/Cellar/php*.

Installing services for Magento 2.4

Since we're running a hybrid docker+local system we need to set up PHP to run locally.

# Magento 2.4 (for 2.3, see the 2.x branch)
# Cleans existing brew php (will not remove Valet stuff) + installs php on OSX!
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/ho-nl/docker-development-box/master/install.sh)"

It will (re)install multiple php-fpm services, one for each version (port: 9072, 9073, 9074) and one for each version with xdebug (port: 9172, 9173, 9174).

Switch PHP versions

brew unlink php@7.3
brew link php@7.4 --force
php -v

Should now show the right version. If it doesn't there might be still be a version linked, or your ~/.bash_profile should be cleaned up, or you need to reopen your CLI.

Install docker

1. Install latest version of docker for mac.
2. Start Docker
3. Exclude ~/Library/Containers from your backups
4. brew install ctop: can be used to show container metrics.
5. Open Docker -> Preferences
6. Set memory to 6-8 GB

Install nfs

Note that the -mapall=501:20 part below refers to your user ID (501) and the staff (20) user group ID. You may need to adjust your user ID if isn't 501. You can check this by running id.

1. sudo nano /etc/exports add: /System/Volumes/Data -alldirs -mapall=501:20 localhost
2. sudo nano /etc/nfs.conf add: nfs.server.mount.require_resv_port = 0
3. sudo nfsd restart

Based on this article

Install local certificate

• Download the raw .pem file (Open Raw, then CMD + S):
• ./hitch/*.localhost.reachdigital.io.pem
• Open keychain.app, add this file (you can drag and drop this file in the keychain app, under the Login tab).
• Open certificate and trust the certificate (do this by right clicking on the entry, choosing 'Get Info', and choose 'Always trust' under the 'Trust' section)

You are now done with the global installation 🎉

Project installation

This covers initially adding docker-devbox support to a Magento project; if your project already has docker-devbox support added, please refer to the projects' own README.md.

• Install this in the project:
  • Magento 2.3: 2.x branch
  • Magento 2.4: composer require reach-digital/docker-devbox ^3.0.0
• Install static-content-deploy patch and remove existing static symlinked content: rm -rf pub/static/*/*.
• Disable services you don't need in docker-compose.yml (required: hitch, varnish, nginx, db and elasticsearch).
• Commit the docker-compose.yml file to prevent future accidental changes.
• Update or create an env.php file and with the following info

    'host' => '127.0.0.1',
    'dbname' => 'magento',
    'username' => 'root',
    'password' => 'magento',
  

• Create a setup script for the base-urls and run it.

Usage

• Start: docker-compose up -d
• Logging: ctop
• Stop: docker-compose down

You now have all services set up 🎉. See individual services below to set urls, caches, etc.

Deleting data (mysql/elasticsearch):

• docker-compose down
• rm -rf var/.esdata/*
• rm -rf var/.mysqldata/*
• docker-compose up -d

Be sure to give MySQL a minute or two to re-initialize the data directory - during this time it will not accept connections.

Settings for mysql elasticsearch, rabbitmq, mailhog, etc.

How do I use xdebug?

• Web: Xdebug should work by default when you have the Xdebug helper installed + PHPStorm is listening to connections.
• Command line: you can add the following alias to your ~/.bash_profile or ~/.zshrc, this will auto-detect your active PHP version, and let you debug using something like phpd bin/magento ...:

  alias phpd="XDEBUG_SESSION=1 php -c \$(brew --prefix)/etc/php/\$(php -v | head -n1 | cut -c 5-7)/php-xdebug.ini"
  

• Tests: Create a local interpreter in PhpStorm, the PHP version you're looking for should be suggested. Configure the 🐞 Xdebug path: to enable xdebug (from the output of the installation script). The path is something like /usr/local/Cellar/php/7.4.3/pecl/20190902/xdebug.so. You can look up your exact path in your php-xdebug.ini.

How do I set up my cron?

default setup

Where can I find logs?

• For all other services, start ctop and press <- on your keyboard.
• phplogs: tail -f `brew --prefix`/var/log/php* (will probably be empty as it will only output true errors)

How do I set up urls/https?

https only with hitch. The docker container does not support http, only https.

bin/magento config:set --lock-env web/unsecure/base_url https://blabla.localhost.reachdigital.io/
bin/magento config:set --lock-env web/secure/base_url https://blabla.localhost.reachdigital.io/
# You can use any domain that points to 127.0.0.1, you can't use https://localhost because Magento can't handle that.
# *.localhost.reachdigital.io always resolves to 127.0.0.1

How do I set up multiple websites?

To allow our nginx setup to work with multiple websites we need change the nginx environment parameter MAGE_RUN_TYPE from store to website

To define our website or storeview codes we have to add a new conf file, for example nginx-map.conf $MAGE_RUN_CODE is the relevant website_code or storeview_code

map $http_host $MAGE_RUN_CODE {
    default '';
    example-dutch.localhost.reachdigital.io 'example_dutch';
    example-german.localhost.reachdigital.io 'example_german';
}

Add the file path to the nginx volumes, for example:

    volumes:
      - ./nginx-map.conf:/etc/nginx/conf.d/map.conf:ro

Your website or storeview should now be available.

For more information check the magento docs: https://experienceleague.adobe.com/docs/commerce-operations/configuration-guide/multi-sites/ms-nginx.html

How do I use and set up Varnish?

Cache by default with https://www.varnish-software.com/

bin/magento setup:config:set --http-cache-hosts=127.0.0.1:6081
bin/magento config:set --lock-config system/full_page_cache/caching_application 2

• You can use bin/magento cache:clean or cache:flush to flush Varnish.
• You can use CMD+SHIFT+R to bypass Varnish for any page.
• You can use port 6082 and docker-devbox-varnish-secret as shared secret to connect with the Varnish management interface.

How do I set up Redis?

php bin/magento setup:config:set --cache-backend=redis --cache-backend-redis-db=0 --cache-backend-redis-port=6379
php bin/magento setup:config:set --session-save=redis --session-save-redis-db=2 --session-save-redis-port=6379

How do I flush Redis directly when bin/magento is broken? docker-compose exec redis redis-cli flushall

How do I set up Elastic Search?

bin/magento config:set --lock-config catalog/search/enable_eav_indexer 0
bin/magento config:set --lock-config catalog/search/engine [elasticsearch7 OR  elasticsuite]
bin/magento config:set --lock-env catalog/search/elasticsearch6_server_port 9200
bin/magento config:set --lock-env catalog/search/elasticsearch6_server_hostname localhost

How do I set up MailHog?

composer require magepal/magento2-gmailsmtpapp
php bin/magento setup:upgrade
bin/magento config:set --lock-env system/smtp/disable 0
bin/magento config:set --lock-env system/gmailsmtpapp/active 1
bin/magento config:set --lock-env system/gmailsmtpapp/auth NONE
bin/magento config:set --lock-env system/gmailsmtpapp/ssl none
bin/magento config:set --lock-env system/gmailsmtpapp/smtphost localhost
bin/magento config:set --lock-env system/gmailsmtpapp/smtpport 1025

Note that when trying to visit MailHog via your browser, use http instead of https.

How do I set up RabbitMQ?

bin/magento setup:config:set --amqp-host=localhost --amqp-port=5672 --amqp-user=guest --amqp-password=guest
http://localhost:15672

How do I set up Ngrok?

Ngrok exposes local servers to the public internet over secure tunnels.

http://localhost:4551
Update base urls with tunnel url shown on webpage.

By default an unregistered session is started, this will limit the connections per minute. Adding your authtoken using environment parameters will grant you access to more features and longer session times.

  - PARAMS=http -region=eu --authtoken=<token> nginx:80

How do I set up Sphinx?

No support yet.

How do I connect to my container over SSH directly?

1. Open up ctop
2. ⮐ on your service
3. exec shell

Please note that the containers are as minimal as possible, so not all common tools are available, but you should be able to get around.

I want to create a custom configuration for a service.

Everything is set up via the docker-compose.yml file. You see paths to the configuration file there.

1. Change the path to your custom configuration file.
2. Run docker-compose down && docker-compose up -d
3. Changes should be applied, check ctop if your container is able to start.

How do I restart php-fpm?

pkill php-fpm

Troubleshooting

The Compose file './docker-compose.yml' is invalid

ERROR: The Compose file './docker-compose.yml' is invalid because: Unsupported config option for services.mailhog: 'platform'

Please update Docker to fix this error. This error happens because your Docker version is too low and does not support the platform option. This option is used in recent versions of docker-development-devbox to enable support for both Intel and Apple Silicon macbooks.

docker-composer and/or ctop are not able to connect to the Docker daemon

ERROR: Couldn't connect to Docker daemon. You might need to start Docker for Mac.

This may happen if you've upgraded from an old version of Docker. In more recent versions of docker, the socket file through which one can connect with the deamon was moved to ~/.docker/run/docker.sock. Programs like ctop and docker-composer use the symlink at /var/run/docker.sock which may still point to the old path.

To correct this, run the following:

sudo ln -sf ~/.docker/run/docker.sock /var/run/docker.sock
