## The playbook now uses external roles for some things
**TLDR**: when updating the playbook and before running it, you'll need to run `make roles` to make [ansible-galaxy](https://docs.ansible.com/ansible/latest/cli/ansible-galaxy.html) download dependency roles (see the [`requirements.yml` file](requirements.yml)) to the `roles/galaxy` directory. Without this, the playbook won't work.
We're in the process of trimming the playbook and making it reuse Ansible roles.
Starting now, the playbook is composed of 2 types of Ansible roles:
- those that live within the playbook itself (`roles/custom/*`)
- those downloaded from other sources (using [ansible-galaxy](https://docs.ansible.com/ansible/latest/cli/ansible-galaxy.html) to `roles/galaxy`, based on the [`requirements.yml` file](requirements.yml)). These roles are maintained by us or by other people from the Ansible community.
We're doing this for greater code-reuse (across Ansible playbooks, including our own related playbooks [gitea-docker-ansible-deploy](https://github.com/spantaleev/gitea-docker-ansible-deploy) and [nextcloud-docker-ansible-deploy](https://github.com/spantaleev/nextcloud-docker-ansible-deploy)) and decreased maintenance burden. Until now, certain features were copy-pasted across playbooks or were maintained separately in each one, with improvements often falling behind. We've also tended to do too much by ourselves - installing Docker on the server from our `matrix-base` role, etc. - something that we'd rather not do anymore by switching to the [geerlingguy.docker](https://galaxy.ansible.com/geerlingguy/docker) role.
Some variable names will change during the transition to having more and more external (galaxy) roles. There's a new `custom/matrix_playbook_migration` role added to the playbook which will tell you about these changes each time you run the playbook.
From now on, every time you update the playbook (well, every time the `requirements.yml` file changes), it's best to run `make roles` to update the roles downloaded from other sources.
If you've [configured your DNS](configuring-dns.md) and have [configured the playbook](configuring-playbook.md), you can start the installation procedure.
**Before installing** and each time you update the playbook in the future, you will need to update the Ansible roles in this playbook by running `make roles`.
## Playbook tags introduction
The Ansible playbook's tasks are tagged, so that certain parts of the Ansible playbook can be run without running all other tasks.
- take a look at [the changelog](../CHANGELOG.md) to see if there have been any backward-incompatible changes that you need to take care of
- re-run the [playbook setup](installing.md): `ansible-playbook -i inventory/hosts setup.yml --tags=setup-all`
- download the upstream Ansible roles used by the playbook by running `make roles`
- restart the services: `ansible-playbook -i inventory/hosts setup.yml --tags=start`
- re-run the [playbook setup](installing.md) and restart all serivces: `ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,ensure-matrix-users-created,start`
**Note**: major version upgrades to the internal PostgreSQL database are not done automatically. To upgrade it, refer to the [upgrading PostgreSQL guide](maintenance-postgres.md#upgrading-postgresql).
matrix_ntpd_package:"{{ 'systemd-timesyncd' if (ansible_os_family == 'RedHat' and ansible_distribution_major_version | int > 7) or (ansible_distribution == 'Ubuntu' and ansible_distribution_major_version | int > 18) else ('systemd' if ansible_os_family == 'Suse' else 'ntp') }}"
matrix_ntpd_service:"{{ 'systemd-timesyncd' if (ansible_os_family == 'RedHat' and ansible_distribution_major_version | int > 7) or (ansible_distribution == 'Ubuntu' and ansible_distribution_major_version | int > 18) or ansible_distribution == 'Archlinux' or ansible_os_family == 'Suse' else ('ntpd' if ansible_os_family == 'RedHat' else 'ntp') }}"
"NOTE: Your appservice-irc database files have been imported into Postgres. The original database files have been moved from `{{ matrix_appservice_irc_data_path }}/*.db` to `{{ matrix_appservice_irc_data_path }}/*.db.backup`. When you've confirmed that the import went well and everything works, you should be able to safely delete these files."
"NOTE: Your appservice-slack database files have been imported into Postgres. The original database files have been moved from `{{ matrix_appservice_slack_data_path }}/*.db` to `{{ matrix_appservice_slack_data_path }}/*.db.backup`. When you've confirmed that the import went well and everything works, you should be able to safely delete these files."
"NOTE: Your mautrix-facebook bridge is still on SQLite and on the last version that supported it, before support was dropped. Support has been subsequently re-added in v0.3.2, so we advise you to upgrade (by removing your `matrix_mautrix_facebook_docker_image` definition from vars.yml)"
