Use the Docker environment

By default, Magento Cloud Docker deploys Magento to a read-only file system in the Docker environment. This deployment mirrors the read-only file system in the Production environment. You have the option to deploy a Docker environment in developer mode, which provides an active development environment with full, writable file system permissions.

You use the ece-docker build:compose command to generate the Docker Compose configuration file from specified configuration settings and to deploy Magento Commerce Cloud to a local Docker environment. You supply the configuration settings from multiple sources depending on your requirements. See Configure sources.

When you run the ece-docker build:compose command, it regenerates the docker-compose.yml configuration file and overwrites the existing docker-compose.yml configuration file. You can save custom configurations across builds by adding the settings to a docker-compose.override.yml file. See a detailed example in the Docker quick reference.

Set the launch mode

You can launch a Docker environment in production or developer mode by setting the mode option on the ece-docker build:compose command:

• Production mode—The --mode="production" setting supports an active production environment with read-only file system permissions. This is the default configuration setting for launching a Docker environment. Selecting this option builds the Docker environment in production mode and verifies configured service versions. See Production mode launch instructions.

• Developer mode—The --mode="developer" setting supports an active development environment with full, writable file system permissions. Selecting this option builds the Docker environment in developer mode and verifies configured service versions. System performance is slower in developer mode because of additional file synchronization operations. See Developer mode launch instructions.

For example, the following command starts the Docker configuration generator for the developer mode:

1
./vendor/bin/ece-docker build:compose --mode="developer"

To skip the interactive mode, use the -n, --no-interaction option.

The mode option for the ece-docker build:compose command does not affect the Magento mode. It determines the Magento Commerce Cloud file system installation and read-only or read-write behavior.

Stop and start containers

You can stop containers and restore them afterwards using the following methods.

Use the following command to stop and remove the Docker configuration:

1
   docker-compose down -v

This command removes all components of your local Docker instance including containers, networks, volumes, and images except for the persistent database and the magento-sync volume. See Rebuild a clean environment.
