Release date: December 21, 2020

  • NGINX command options–Added build command options to change the number of NGINX worker_processes and NGINX worker_connections for TLS and Web services. The worker_process parameter retains the ability to set the value to auto. Examples:

     ./vendor/bin/ece-docker build:compose --nginx-worker-processes=2
     ./vendor/bin/ece-docker build:compose --nginx-worker-connections=2048
  • TLS command option–Added build command option to create a configuration without the TLS service. Example:

    ./vendor/bin/ece-docker build:compose --no-tls
  • NGINX memory consumption–Reduced the memory consumed by the NGINX process for TLS and Web services.

  • Blackfire–Disabled Blackfire PHP extension by default in the Cloud Docker image.

  • PHP-FPM container–Fixed PHP-FPM container health check by changing the WEB_PORT from 80 to 8080.

  • Invalid volume naming–Fixed an error with invalid volume naming in developer mode.

  • NGINX upstream port—Updated the Docker NGINX 1.19 image to use port 8080 to avoid an infinite loop. Fix submitted by Adarsh Manickam.


Release date: November 9, 2020

  • Container updates–

    • PHP-FPM container–Added support for the gnupg PHP extension. Fix submitted by G Arvind from Zilker Technology.

    • Database container–Fixed the database container health check by adding the required database password to the health check command.

    • Elasticsearch container

      • Added support for Elasticsearch 7.9 for compatibility with upcoming Magento releases.

      • Elasticsearch plugin configuration–Added support to use the Elasticsearch plugin configuration information from the services.yaml file to generate the docker-compose.yaml file for a Magento Cloud Docker environment. See Elasticsearch plugins.

      • Elasticsearch plugin support–Added support for the following Elasticsearch plugins: analysis-icu, analysis-phonetic, analysis-stempel, and analysis-nori. The analysis-icu and analysis-phonetic plugins are installed by default. You can add or remove the analysis-stempel and analysis-nori plugins as needed.

    • CLI container

      • Run commands inside Docker PHP containers–Now you can use the Magento Cloud Docker CLI to run commands inside PHP containers in your Docker environment without having to install PHP on the host. For example, the following command builds the configuration: ./bin/magento-docker php 7.3 vendor/bin/ece-docker build:compose. See Magento Cloud Docker CLI. Fix submitted by G Arvind from Zilker Technology.

      • Added the OpenSSH-client to PHP CLI containers. Now, you can use ssh-agent forwarding for Composer if the composer.json file contains private git repositories that require an ssh client to use Composer commands.

    • TLS container–Now, the TLS container is based on the Docker image instead of the Centos image. This change fixes issues that caused errors when sending HTTPS requests between containers in the Cloud Docker environment.

    • Test container–Added a test container for Magento application testing, and added the --with-test option to the Docker build:compose command to create the container only when testing Magento in the Docker environment. See Magento application testing.

    • FPM-XDEBUG container

      • Configure Xdebug on Linux–Added the --set-docker-host option to the ece-docker build:compose command to configure the host.docker.internal value in the Xdebug container. This option is required to use Xdebug on Linux systems. See Configure Xdebug for Docker.

      • Fixed the Xdebug variable configuration for the Docker ENTRYPOINT to resolve uninitialized "with_xdebug" variable errors in the logs. Fix submitted by Florent Olivaud

  • Docker configuration changes

    • MailHog configuration–Now you can use the following ece-docker build:compose command options to disable MailHog and specify ports: --no-mailhog, --mailhog-http-port, and --mailhog-smtp-port. See Set up email.

    • For Magento Cloud Docker 1.2.0 and later, Magento now provides Docker images for each patch version, and the Docker configuration generator creates the Docker configuration with a specified patch version instead of using the latest. Previously, the Docker configuration generator built the configuration using the latest patch version which could break Magento Cloud Docker environments built using an earlier version.

    • Specify custom images and versions in custom Magento Cloud Docker configuration—Updated the build:custom:compose command with options to specify custom images and versions when generating a custom Docker compose configuration file (docker-compose.yaml). See Build a custom Docker Compose configuration.

    • Updated the Docker host configuration to expose port 443 to enable access to Magento (https://magento2.docker) from all CLI containers. You can change the default port by adding the --tls-port option when you generate the Docker configuration file.

  • Fixed an issue that caused the Magento Cloud Docker build to fail if the app/etc/env.php file exists.

  • Updated the build configuration to replace named volumes with regular volumes to prevent issues when deploying Magento Cloud Docker on Linux or Windows Subsystem for Linux (WSL2).

  • Updated the Magento Cloud Docker functional tests to support Composer 2.0.


Release date: September 9, 2020

  • Added support for Elasticsearch 7.7


Release date: August 5, 2020

  • Updated email configuration–Updated the default configuration to support the MailHog service instead of using SendMail. See Set up email.

  • Restored the PS library to the Cloud Docker environment configuration to fix ps: command not found errors.

  • Updated the default Magento Cloud Docker configuration to remove automatic mounting of the database entrypoint and MariaDB volumes to fix Cannot create container for service db errors that can occur when starting your Cloud Docker environment.

    Now, you can configure the Cloud Docker environment to mount the database directories by adding the following options to the ece-docker build:compose command: --with-entry-point and with-mariadb-conf. See Service configuration options.

  • CLI command updates

Action Command
Add an entrypoint to the database container to restore the database from backup ./vendor/bin/ece-docker build:compose --db --with-entrypoint
Add a MariaDB configuration volume ./vendor/bin/ece-docker build:compose --db --mariadb-conf


Release date: June 25, 2020

  • Added support for the Magento split database performance solution–Now you can configure and deploy a Magento store using the Magento Split database performance solution in the Cloud Docker environment.

  • Support for Magento Commerce and Magento Open Source deployment–Now you can use Magento Cloud Docker to deploy a local development environment for projects that are not hosted on the Magento Cloud platform.

  • support–Added support to use the extension for automated performance testing. Fix submitted by Adarsh Manickam from Zilker Technology

  • Container updates

    • Varnish—Now Varnish is the default cache when you deploy Magento in a Cloud Docker environment using a supported version of the Magento Cloud application template. See Varnish container.

    • Added the --no-varnish option to skip Varnish service installation when you generate the Cloud Docker configuration file.

    • Database

      • Added the support for the MySQL database. Now, you can configure the Cloud Docker environment with either MariaDB or MySQL. See Service configuration options.

      • Added the ability to set the increment and offset settings for database replication when you generate the Docker compose file. See Service containers.

    • PHP-FPM

    • Node.js—Updated the default Node.js version from version 8 to version 10 to improve security. Node.js version 8 is deprecated and no longer updated with bug fixes or security patches. Fix submitted by Mohan Elamurugan from Zilker Technology.

    • Elasticsearch

      • Added support for Elasticsearch 6.8, 7.2, 7.5, and 7.6.

      • Added the ability to customize the Elasticsearch container configuration when you generate the Docker compose configuration file.

      • Added the --no-es option to the service configuration options for generating the Docker Compose configuration file. Use this option to skip the Elasticsearch container installation and use MySQL search instead. This option is supported only for Magento versions 2.3.5 and earlier.

    • FPM-XDEBUG container—Added a service configuration option to install and configure Xdebug for debugging PHP in your Cloud Docker environment. See Configure Xdebug.

  • Docker configuration changes

    • Added health checks for the PHP-FPM, Redis, Elasticsearch, and MySQL Docker service containers.

    • Changed the default file synchronization mode to native in Developer mode.

    • Added version information to the generic Docker service container image when generating the docker-compose.yml file.

    • Improved ability to handle large responses from the upstream PHP-FPM container by increasing the fastcgi_buffers value for the Nginx server.

    • Improved mutagen file synchronization performance by adding a second sync session to synchronize files in the vendor directory. This change prevents mutagen from getting stuck during the file synchronization process. Fix submitted by Mathew Beane from Zilker Technology.

    • CLI command updates

      Action Command
      Clear Redis cache bin/magento-docker flush-redis
      Clear Varnish cache bin/magento-docker flush-varnish
      Skip default Varnish installation .vendor/bin/ece-docker build:compose --no-varnish
      Customize Elasticsearch options .vendor/bin/ece-docker build:compose --es-env-var
      Remove Elasticsearch configuration .vendor/bin/ece-docker build:compose --no-es
      Configure DB container with MySQL version 5.6 or 5.7 ./vendor/bin/ece-docker build:compose --db <mysql-version-number> --db-image mysql
      Specify custom Magento base URL ./vendor/bin/ece-docker build:compose --host=<hostname> --port=<port-number>
      Add container for Xdebug configuration .vendor/bin/ece-docker build:compose --mode developer --sync-engine native --with-xdebug
  • Fixed the configuration of mutagen file synchronization to prevent mutagen from creating stale sessions. Fix submitted by Mathew Beane from Zilker Technology.

  • Fixed a configuration issue that caused syntax errors in the Docker compose log when starting the PHP-FPM container. Fix submitted by Mathew Beane from Zilker Technology

  • Fixed volume conflict errors that sometimes occurred when using multiple Docker environments. Fix submitted by G Arvind from Zilker Technology.

  • Fixed an issue that caused the ece-docker build:compose command to fail if the configuration included Fix submitted by G Arvind from Zilker Technology.

  • Updated the PHP CLI image configuration to prevent out-of-memory errors that occurred when installing multiple packages using Magento Cloud Docker. Fix submitted by Mohan Elamurugan from Zilker Technology.

  • Added support for multiple MySQL users in the Cloud Docker environment. In earlier releases, the build:compose operation failed if the file specified multiple database users. Fix submitted by G Arvind from Zilker Technology.

  • Removed rsyslog from the Magento Cloud Docker PHP containers to resolve compatibility issues that caused warning notifications during deployment. Magento Cloud Docker does not use the rsyslog utility.


Release date: Feb 5, 2020

  • Created a separate package to deliver Magento Cloud Docker–Moved the source code to deliver Magento Cloud Docker from the ece-tools repository to the new magento-cloud-docker repository to maintain code quality and provide independent releases. The new package is a dependency for ece-tools v2002.1.0 and later.

    When you update ece-tools, you also update the magento/magento-cloud-docker package to version 1.0.0. If you used Magento Cloud Docker with an earlier ece-tools release (2002.0.x), review the backward incompatibilities and update your project as scripts, commands, and processes as needed.

  • Added versioning to the Docker images–You must now update the magento/magento-cloud-docker package to get the updated images.

  • Container updates

    • PHP-FPM container

      • Added Node.js support–Updated the PHP-FPM image to support node, npm, and the grunt-cli capabilities inside the PHP container.

      • Added support for ionCube–Updated the default Docker configuration to support ionCube in the local Docker development environment.

    • Web container

      • Customize NGINX configuration–Added the capability to mount a custom nginx.conf file to the Magento Cloud Docker environment. See Web container.

      • Auto-generated NGINX certificates–The Docker configuration file now includes the configuration to auto-generate NGINX certificates for the Web container.

    • New Selenium container–Added a Selenium container to support Magento Commerce application testing using the Magento Functional Testing Framework (MFTF).

    • RabbitMQ version support–Updated the RabbitMQ container configuration to support RabbitMQ version 3.8.

    • Persistent database container–The magento-db: /var/lib/mysql database volume now persists after you stop and remove the Docker configuration and restores when you restart the Docker configuration. Now, you must manually delete the database volume. See Database containers.

    • TLS container

      • Updated the container base image to use official image–The Magento Cloud TLS container image is now based on the official debian:jessie Docker image.–

      • Added support for the Pound TLS Termination Proxy–The Pound configuration file adds the following ENV variables to customize the Docker configuration for the TLS container:

        • TimeOut–Sets the Time to First Byte (TTFB) timeout value. The default value is 300 seconds.

        • RewriteLocation–Determines whether the Pound proxy rewrites the location to the request URL by default. Defaults to 0 to prevent the rewrite from breaking redirects to outside websites like an external SSO site. Fix submitted by Sorin Sugar

      • Increased the timeout value in the TLS container configuration from 15 to 300 seconds. Fix submitted by Mathew Beane from Zilker Technology

    • Varnish container

  • Docker configuration changes

    • Manage mounts and volumes for your project–Added the ability to manage mounts and volumes when launching a Docker environment for local development. See Sharing Magento Cloud project data.

    • Support for network bridge mode–Added support for network bridge mode to enable connections between Docker containers over the local network.

    • Cron container disabled by default–To improve performance, the Cron container is no longer configured by default when you build the Docker environment. You can use the --with-cron option on the Docker build command to add a Cron container to your environment. See Managing cron jobs.

    • Stop synchronizing large backup files–Added DB dumps and archive files—ZIP, SQL, GZ, and BZ2—to the exclusion list in the dist/docker-sync.yml and dist/ files. Synchronizing large files (>1 GB) can cause a period of inactivity and backup files do not normally require synchronization since you can regenerate them.

  • Command changes

    • Renamed the ./bin/docker file to ./bin/magento-docker to fix an issue that caused some Docker environments to break because the ./bin/docker file overwrites existing Docker binary files. This is a backward incompatible change that requires updates to your scripts and commands.

    • Added a service configuration option to expose the database port to the host–Use the --expose-db-port=<PORT> option to expose the database port to the host when building the docker-compose.yml file: bin/ece-docker build:compose --expose-db-port=<PORT> Fix submitted by Adarsh Manickam from Zilker Technology.

    • New post-deploy command–Previously, the post-deploy hooks defined in the file ran automatically after you deployed Magento to a Cloud Docker container using the cloud-deploy command. Now, you must issue a separate cloud-post-deploy command to run the post-deploy hooks after you deploy. See the updated launch instructions for developer and production mode.

    • Added the --rm option to ./bin/magento-docker commands for the build and deploy containers. This removes the container after the task is complete.

    • Updates to build:compose command

      • Added the --sync-engine="native" option to the docker-build command to disable file synchronization when you generate the Docker Compose configuration file in developer mode. Use this option when developing on Linux systems, which do not require file synchronization for local Docker development. See Synchronizing data in the Docker environment.
    • Changed the default file synchronization setting from docker-sync to native. Fix submitted by Mathew Beane from Zilker Technology.

  • Validation improvements

    • Added validation to the deployment process for local Docker development environments to verify that the Cloud environment configuration includes the encryption key required to decrypt the database. Now, you get an error message in the log if the environment configuration does not specify a value for the encryption key.

    • Added a container health check to the Elasticsearch service to ensure that the service is ready before continuing with build and deploy processing. If the health check returns an error, the container restarts automatically.
