Extend the Docker configuration
You can use the built-in extension mechanism of Docker to specify multiple compose files. The following example replaces the default value of the ENABLE_SENDMAIL
environment variable.
-
Create a
docker-compose-dev.yml
file inside your project root directory and add the following content:1 2 3 4 5
version: '2' services: deploy: environment: - ENABLE_SENDMAIL=true
-
Pass both configuration files while executing your commands. For example:
1
docker-compose -f docker-compose.yml -f docker-compose-dev.yml run deploy bash
Specify Docker build sources
To test changes to images or make more extensive changes to the containers, you must build them from source. You can do this by
by adding the build:context
configuration to the docker-compose.override.yml
file.
The following example defines the build context for the Web container. You can use the same technique to build from any of the images in the vendor/magento/magento-cloud-docker
directory or any other Docker image, including local images that are resourced outside the project.
1
2
3
4
5
version: '2.1'
services:
web:
build:
context: ./vendor/magento/magento-cloud-docker/images/nginx/1.9/
To update the container configuration and test iteratively, use the --force-recreate
option to refresh the container build:
1
docker-compose up -d --force-recreate --build
Add a new version of existing service
In package the available service versions are determined by the Docker service images configured in the images
directory. You can add a new service version by creating a directory for the version and adding a Dockerfile
and other files to configure the new version.
To add a new service version using a Dockerfile
:
-
Clone the `` project to your local environment if necessary.
-
On the command line, change to the directory that contains the existing service version configurations.
1
cd magento-cloud-docker/images/<service-name>
-
Create a directory for the new version.
-
In the new directory, add the
Dockerfile
that contains the image configuration details for the new version. Use theDockerfile
for an existing version as a template and add any other required configuration such as supported plugins. -
Add the
docker-entrypoint.sh
andhealthcheck
files if needed. -
Add any necessary
.conf
and.ini
files for the service to theetc
directory. -
Run the following command to build the image.
docker build -t test/<service-name>:<service-version>
-
Once the build succeeds, test the changes by specifying the Docker build sources.
Add a new PHP extension
In addition to built-in extensions, you can add PHP extensions to the PHP container.
To add a new PHP extension:
-
Clone the `` project to your local environment if necessary.
-
On the command line, navigate to the PHP directory.
```bash cd magento-cloud-docker/src/Compose/Php
-
Open the
ExtensionResolver.php
file, define the required extension inside thegetConfig
method by specifying the extension type and dependency.For instance the following block adds the GNUPG extension:
1 2 3 4 5
'gnupg' => [ '>=7.0' => [ self::EXTENSION_TYPE => self::EXTENSION_TYPE_PECL, self::EXTENSION_OS_DEPENDENCIES => ['libgpgme11-dev'], ],],
The extension type can be either CORE or PECL, which are defined as
EXTENSION_TYPE_PECL
orEXTENSION_TYPE_CORE
respectively. -
Add any required
.ini
files to the PHP FPM container configuration.-
On the command line, navigate to FPM image directory
magento-cloud-docker/images/php/fpm
:1
cd ../../../images/php/fpm
-
Add each required
.ini
file to theetc
directory. -
For each
.ini
file that you add, you must add the following line to theDockerfile
(magento-cloud-docker/images/php/fpm/Dockerfile
):1
COPY etc/<filename>.ini /usr/local/etc/php/conf.d/<filename>.ini
-
-
Add any required
.ini
files to the PHP CLI container configuration.-
On the command line, navigate to the CLI image directory
magento-cloud-docker/images/php/cli
.1
cd ../cli
-
Add each required
.ini
file to theetc
directory. -
For each
.ini
file that you add, you must add the following line to theDockerfile
(magento-cloud-docker/images/php/cli/Dockerfile
):1
ADD etc/<file-name>.ini /usr/local/etc/php/conf.d/<filename>.ini
-
-
Generate an updated
Dockerfile
for all PHP image versions included in the package.1
bin/ece-docker image:generate:php
-
Test the extension by specifying the Docker build sources.
