 Ansible role EteBase - EteSync 2.0 Server Backend
===================================================
Ansible role to Setup and Confugure Etebase - The Backend from [EteSync](https://www.etesync.com/) 2.0 -> [https://github.com/etesync/server](https://github.com/etesync/server.git).

 Details
---------
This Ansible role installs and configures etebase, the backend of etesync. A piece of software to securely sync your contacts, calendars, tasks and notes!
In this Ansible role, a separate user is created for etebase. The latest release of etebase is downloaded to the home of this user. A configuration is created. The specified Python dependencies are installed in a venv. And optionally etebase can be started automatically via a systemd service and uvicorn.

This Ansible role does not create users in Etebase. And the configuration for the web server is not created either. More about this in the [Additional Information](#additional-information) section.

 Additional Information
------------------------
You find more information about the webserver config at [github.com/etesync/server/wiki/Production-setup-using-Nginx](https://github.com/etesync/server/wiki/Production-setup-using-Nginx). Please remember the value you used for the ``etebase__socket`` variable, if you used this role to start the [uvicorn](https://www.uvicorn.org/) ASGI server via systemd. For this you have to set ``etebase__systemd_setup`` to ``true``.

You have to create a admin User by yourself. To do this, log in manually as priviledged user, change to the ``etebase__user_home``. Enter the downloaded etebase code direcotory and run the ``python3 ./manage.py createsuperuser`` command in the venv:
```bash
# go to etebase home
cd /var/lib/etebase/

# change to latest etebase version
ls -l etebase_*
cd etebase_v0.10.0  # example versiom

# enable latest venv
ls -l /var/lib/etebase/venv
source /var/lib/etebase/venv/v0.10.0/bin/activate  # example version

# create new superuser
python3 ./manage.py createsuperuser
```

By the way, this role requires that the Ansible user be allowed to execute commands with sudo privileges.

 Example Playbook
------------------
```yml
---
- name: Install etebase server at example.com
  hosts: example.com
  roles:
    - {role: do1jlr.etebase, tags: etebase}
  vars:
    etebase__allowed_hosts_allowed_host1: 'example.com'
    etebase__systemd_setup: true
    submodules_versioncheck: true
```
