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
In order to be able to use
drush site:alias-convert , you need to do the following:
- Rename the
Generate Site Aliases#
You can now convert your Drush aliases by running the following command in your project using the
docker-compose exec cli drush site:alias-convert /app/drush/sites --yes
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
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:
drush rsync @self:%files @lagoon.main:%files -- --omit-dir-times --no-perms --no-group --no-owner --chmod=ugo=rwX
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.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:
drush rsync @lagoon.main:%files @self:%files -- --omit-dir-times --no-perms --no-group --no-owner --chmod=ugo=rwX
This is not necessary if you
rsync from a remote to a local environment.
Also, we're working with the Drush maintainers to find a way to inject this automatically.
