Can I run a multisite application on Cloud IDE?

Cloud IDE has one preview URL, which means you can only serve one site at a time. When running the acli pull command, you can select any arbitrary database or files directory to pull from. You can switch sites at any point in time by using the acli pull command again and pulling a different database and files directory.

Cloud IDE only recognizes the sites/default directory by default. To serve other sites in other directories, we recommend you to use path-based multisite.

To configure path-based multisite for an example site located under sites/foo:

• Pull your application in Cloud IDE. Ensure that you pull the database and files directory that correspond to the foo site.
• Add a foo symlink in the docroot directory, for example, cd /home/ide/project/docroot && ln -s . foo, so that Drupal does not try to serve the foo path.
• Modify /home/ide/project/docroot/sites/sites.php to add $sites = ['cloud.foo' => 'foo'];. The first foo must match the symlink / path to access the multisite, and the second foo must match the name of the site directory on the disk. These are generally same but not always.
