Lagoon defaults to Drush 8. Drush 9 is used if you install Drush 9 into your Drupal site via Composer.
Unfortunately, Drush 9 does not provide the ability to inject dynamic site aliases like Drush 8 did. We are working with the Drush team to implement this again. In the meantime, we have a workaround that allows you to use Drush 9 with Lagoon.
Drush 9 provides a new command, drush site:alias-convert , which can convert Drush 8-style site aliases over to the Drush 9 YAML site alias style. This will create a on- time export of the site aliases currently existing in Lagoon, and save them in /app/drush/sites . These are then used when running a command like drush sa.
In order to be able to use drush site:alias-convert , you need to do the following:
Rename the aliases.drushrc.php inside the drush folder to lagoon.aliases.drushrc.php.
Generate Site Aliases
You can now convert your Drush aliases by running the following command in your project using the cli container:
It's good practice to commit the resulting YAML files into your Git repository, so that they are in place for your fellow developers.
Use Site Aliases
In Drush 9, all site aliases are prefixed with a group. In our case, this is lagoon. You can show all site aliases with their prefix via:
drush sa --format=list
and to use them:
drush @lagoon.main ssh
Update Site Aliases
If a new environment in Lagoon has been created, you can run drush site:alias-convert to update the site aliases file. If running this command does not update lagoon.site.yml, try deleting lagoon.site.yml first, and then re-run drush site:alias-convert.
Drush rsync from local to remote environments
If you would like to sync files from a local environment to a remote environment, you need to pass additional parameters:
This also applies to syncing one remote environment to another, if you're not using the Lagoon tasks UI to copy files between environments.
For example, if you wanted to sync the files from @lagoon.main to @lagoon.dev , and ran drush rsync @lagoon.main @lagoon.dev locally, without the extra parameters, you would probably run into a "Cannot specify two remote aliases" error.
To resolve this, you would first need to SSH into your destination environment drush @lagoon.dev ssh, and then execute the rsync command with parameters similar to the above:
