Docker Configuration for Magento 2

Deploy secure and flexible docker infrastructure for Magento 2 in a matter of seconds.

🚀 Deploy your project:

Disclaimer: By default, the latest versions of packages are configured, above those recommended by Magento 2

Install Docker:

you can use any linux host or Docker Desktop
https://docs.docker.com/
https://docs.docker.com/engine/install/debian/

    curl -fsSL https://get.docker.com -o get-docker.sh
    bash get-docker.sh

Install docker compose v2:

  mkdir -p ~/.docker/cli-plugins/  
  curl -SL https://github.com/docker/compose/releases/latest/download/docker-compose-linux-x86_64 \
  -o ~/.docker/cli-plugins/docker-compose  
  chmod +x ~/.docker/cli-plugins/docker-compose

Add alias or use auto completion feature:

  echo "alias doco='docker compose'" >> ~/.bash_profile
  . ~/.bash_profile

Create deployment directory:

  mkdir magento && cd magento

Clone repo:

  git clone https://github.com/magenx/Magento-2-docker-configuration.git .

To avoid copying default passwords and hacking through open ports - generate new passwords:

https://docs.docker.com/compose/compose-file/compose-file-v3/#secrets

   bash passgen.sh

When mariadb is started for the first time, a new database with the specified name will be created and initialized with the provided configuration variables. Furthermore, it will execute files with extensions .sh, .sql, .sql.gz, .sql.xz and .sql.zst that are found in ./mariadb/

[ ! ] Check all data, adjust your settings, edit your variables

Run to pull and build images and start containers:

to enable buildkit:
echo '{ "features": { "buildkit": true } }' > /etc/docker/daemon.json
or export DOCKER_BUILDKIT=1

   doco build --no-cache php       
   doco up -d

Watch syslog for errors and issues:

   tail -f /var/log/syslog

To request TLS/SSL certificate with certbot you can run this command [--staging] to test:

  doco stop nginx  
  doco run -p 80:80 --rm certbot certonly \
  --email ${ADMIN_EMAIL} --agree-tos --no-eff-email --standalone -d ${DOMAIN} --staging  
  doco start nginx

change your nginx configuration to uncomment tls/ssl
remove [--staging] flag to reissue live certificate

To request TLS/SSL certificate with certbot in realtime you can run this command:

  doco run --rm certbot certonly \
  --email ${ADMIN_EMAIL} --agree-tos --no-eff-email --webroot -w ${WEB_ROOT_PATH} -d ${DOMAIN}  
  doco restart nginx

Get random mariadb root password from log:

doco logs mariadb 2>&1 | grep GENERATED
magenx-mariadb   | 2021-11-16 08:48:17-05:00 [Note] [Entrypoint]: GENERATED ROOT PASSWORD: m5.QyKl.PS8o<Yx|Jv(~DV&9cY-`i~XZ

Example how to run composer or magento command from host:

magento entrypoint is n98-magerun2 script, looks like providing more commands and options

   doco run --rm composer update
   doco run --rm magento module:status --enabled
   doco run --rm magento module:disable Magento_TwoFactorAuth

Source variables and issue magento installation command for example:

    doco run --rm magento setup:install --base-url=http://${DOMAIN}/ \
   --db-host=mariadb \
   --db-name=${MARIADB_NAME} \
   --db-user=${MARIADB_USER} \
   --db-password='${MARIADB_PASSWORD}' \
   --admin-firstname=${ADMIN_FIRSTNAME} \
   --admin-lastname=${ADMIN_LASTNAME} \
   --admin-email=${ADMIN_EMAIL} \
   --admin-user=${ADMIN_LOGIN} \
   --admin-password='${ADMIN_PASSWORD}' \
   --language=${LOCALE} \

   --session-save-redis-password='${REDIS_PASSWORD}' \
   --use-rewrites=1 \
