Using different Drush versions in containers

Because Acquia Cloud containers support several versions of Drush, Acquia Cloud provides a set of aliases that you can use to access specific Drush major versions for your use.

To run a specific version of Drush, specify the major version in the drush command. For example:

  • Drush 8 - drush8
  • Drush 7 - drush7
  • Drush 6 - drush6

To run the default version of Drush, use the command drush (which in Acquia Cloud containers is currently Drush 8).

Note for pipelines feature users

Acquia strongly recommends that you always run a specific major version of Drush. Running the default version of Drush is dangerous because the behavior of your build definition file may change unexpectedly when a new version of Drush becomes the default.

Using Drush 9 with your container

Drush 9 is not installed in your Acquia Cloud-supplied container. If you want to use Drush 9 with your application, you must include it as a requirement in your application’s composer.json file.
