# laurivan.plausible
THis is a role to install [Plausible](https://plausible.io/) via Docker.
## Requirements
You need a machine with Docker installed.
## Role Variables
Plausible depends on several components (SMTP, Clickhouse, PostgreSQL) and this role is designed to install them as a package. All variables are listed below (see also `defaults/main.yml`).
# Plausible parameters
`plausible_port` defined the exposed port for the web site (including JS delivery and API):
```yaml
plausible_port: 8000
```
You need an admin user to be able to access the site:
```yaml
plausible_admin_user_email: changeme@example.com
plausible_admin_user_name: change-me
plausible_admin_user_pwd: change-me
```
The hosting URL of the server, used for URL generation must be specified:
```yaml
plausible_base_url: change-me
```
Please define a long (>= 64 characters) secret key, which will be used by your instance to encrypt data:
```yaml
plausible_secret_key_base: change-me
```
# Email
Plausible can send various emails; for this it needs a SMTP relay. Following variables define the SMTP account from which emails will be sent:
```yaml
plausible_smtp_host:
plausible_smtp_port: 587
plausible_smtp_username:
plausible_smtp_password:
```
If you don't define any, no emails will be sent and you'll need to look through the logs :)
The email on behalf of which messages are sent is defined by:
```yaml
plausible_smtp_email: "changeme@example.com"
```
## Database
Plausible depends on PostgreSQL and Clickhouse.
For PostgreSQL, you need to specify following variables:
```yaml
plausible_db_host: "plausible_db"
plausible_db: "plausible"
plausible_db_password: "change_me"
```
If you want to expose the database port outside (e.g. for backup), please define `plausible_db_port`
For Clickhouse, you only need to define the version used:
```yaml
plausible_clickhouse_version: "21.3.2.5"
```
### Volumes
The role will create following paths used by the docker containers as volumes:
```yaml
plausible_volume_base: "/mnt/plausible"
plausible_volume_config: "{{ plausible_volume_base }}/config"
plausible_volume_db: "{{ plausible_volume_base }}/db_data"
plausible_volume_events: "{{ plausible_volume_base }}/event_data"
plausible_volume_geoip: "{{ plausible_volume_base }}/geoip_data"
```
The `plausible_volume_geoip` is necessary to access MaxMind GeoIP data (see below).
### GeoIP
Plausible defaults to DBIP, but can be configured to use MaxMind GeoIP. If you want to use MaxMind, you need to define:
```yaml
plausible_geoip_db: "GeoLite2-Country.mmdb"
```
## Dependencies
None
## Example Playbook
```yaml
