Developing with Drupal

Push changes to an environment

Here, we'll see how to make code changes to an environment.

note You should never be working on the Master branch since it's supposed to be your production environment.

Make sure you're on a working environment. In this example we're on the sprint1 branch:

$ git checkout sprint1

Now that you're set up on your working branch, you can start developing on your website by making code changes and pushing those changes to to test them live.

There are three common ways you will be making code changes to Platform:

  1. Add contributed modules, themes, distributions, third-party libraries in the make file
  2. Create custom code (modules, themes, profiles, libraries) and commit them to your codebase
  3. Modify the services grid configuration

Add contributed projects

Each time you push a commit, will rebuild your environment and run the Composer command if a proper composer.json file has been found.

Add a Drupal module or theme

Each Drupal module or theme you want to install on your project should be included in your composer.json file. For example:

$ composer require drupal/token

That will update your composer.json and composer.lock files, which you can then commit.

If you're using Composer, 3rd party PHP libraries can be added in the exact same way as Drupal modules.

Add custom code

To commit your custom modules, themes, or libraries, add those to the web/modules/custom or web/themes/custom directory and commit them to Git as normal.

Change the services configuration

You can change and define the topology of the services used in an environment, by modifying the configuration files.

This means that you're able to define and configure the services you want to use.

Push your changes

When you're done, commit your changes to test them on your online environment.

$ git add .
$ git commit -m "Made changes to my files."
$ git push

You will see that Platform has found a make file and is starting to rebuild your environment.

When it's completed, you can see your changes on your site by clicking View this website under the name of Sprint1 environment on the management console.

note The build process makes no changes to your Git repository. Your Git repository is the input of the process. A PHP container containing your code and dependencies is the output. You can see the directory structure that has been created by connecting via SSH to the environment. See the information in the Access information below the title of the environment

Merge code changes to Master

Once you've got a branch with some changes, you'll want to be able to push those changes up to your live environment. has a great button called Merge that you can click on and it will push the appropriate changes to master.

Merge your changes.

A dialog box will appear that will provide commands to execute future merges from the command line using the CLI.

Merge confirmation cli

Just click on the "Merge" button again and all of the commits you made on your branch will be merged into the master environment.

Synchronizing data

The easiest way to do that is to use Drush and the sql-sync command. You'll need to have Drush aliases for both your site and your local site. If you are using the CLI and you've run platform get [platform_id] for a project, then your Drush aliases have already been set up.

With the Drush aliases (depending on how yours are set up), you could use a command similar to this:

$ drush sql-sync @platform.master @platform._local

An alternate method that is appropriate for larger databases is to use the pipe | to stream the data, instead of making a copy of the dump file.

$ drush @platform.master sql-dump | drush @platform._local sqlc
