Run a specific set of tagged tasks

You can filter which part of the provisioning process to run by specifying a set of tags using the DRUPALVM_ANSIBLE_TAGS environment variable.

# E.g. xdebug, drupal, webserver, database, cron...
DRUPALVM_ANSIBLE_TAGS=xdebug vagrant provision

# Or combine them (e.g. if adding new databases and virtualhosts).
DRUPALVM_ANSIBLE_TAGS=webserver,database vagrant provision

Passing arguments to ansible during a provision

You can specify an additional argument to the ansible-playbook command by using the DRUPALVM_ANSIBLE_ARGS environment variable. This can be useful when debugging a task failure.

Note the following caveats:

• Passing more than one argument may require special formatting. Read the Ansible provisioner's raw_arguments docs for more info.
• You should not quote a flag's value as you would normally do in the shell.

Display verbose ansible output:

DRUPALVM_ANSIBLE_ARGS='--verbose' vagrant provision

Begin the provisioning at a particular task:

DRUPALVM_ANSIBLE_ARGS="--start-at-task '*post-provision shell*'" vagrant provision

Override a config variable:

DRUPALVM_ANSIBLE_ARGS='--extra-vars "drupal_db_backend=pgsql"' vagrant provision
