# Setting up Buscarron (optional)
|
|
|
|
The playbook can install and configure [Buscarron](https://github.com/etkecc/buscarron) for you.
|
|
|
|
Buscarron is bot that receives HTTP POST submissions of web forms and forwards them to a Matrix room.
|
|
|
|
## Adjusting the playbook configuration
|
|
|
|
To enable Buscarron, add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file:
|
|
|
|
```yaml
|
|
matrix_bot_buscarron_enabled: true
|
|
|
|
# Uncomment and adjust this part if you'd like to use a username different than the default
|
|
# matrix_bot_buscarron_login: bot.buscarron
|
|
|
|
# Generate a strong password for the bot. You can create one with a command like `pwgen -s 64 1`.
|
|
matrix_bot_buscarron_password: PASSWORD_FOR_THE_BOT
|
|
|
|
# Adjust accepted forms
|
|
matrix_bot_buscarron_forms:
|
|
- name: contact # (mandatory) Your form name, will be used as endpoint, eg: buscarron.example.com/contact
|
|
room: "!qporfwt:{{ matrix_domain }}" # (mandatory) Room ID where form submission will be posted
|
|
redirect: https://example.com # (mandatory) To what page user will be redirected after the form submission
|
|
ratelimit: 1r/m # (optional) rate limit of the form, format: <max requests>r/<interval:s,m>, eg: 1r/s or 54r/m
|
|
hasemail: 1 # (optional) form has "email" field that should be validated
|
|
extensions: [] # (optional) list of form extensions (not used yet)
|
|
|
|
matrix_bot_buscarron_spamlist: [] # (optional) list of emails/domains/hosts (with wildcards support) that should be rejected automatically
|
|
```
|
|
|
|
### Adjusting the Buscarron URL
|
|
|
|
By default, this playbook installs Buscarron on the `buscarron.` subdomain (`buscarron.example.com`) and requires you to [adjust your DNS records](#adjusting-dns-records).
|
|
|
|
By tweaking the `matrix_bot_buscarron_hostname` and `matrix_bot_buscarron_path_prefix` variables, you can easily make the service available at a **different hostname and/or path** than the default one.
|
|
|
|
Example additional configuration for your `inventory/host_vars/matrix.example.com/vars.yml` file:
|
|
|
|
```yaml
|
|
# Switch to the domain used for Matrix services (`matrix.example.com`),
|
|
# so we won't need to add additional DNS records for Buscarron.
|
|
matrix_bot_buscarron_hostname: "{{ matrix_server_fqn_matrix }}"
|
|
|
|
# Expose under the /buscarron subpath
|
|
matrix_bot_buscarron_path_prefix: /buscarron
|
|
```
|
|
|
|
## Adjusting DNS records
|
|
|
|
Once you've decided on the domain and path, **you may need to adjust your DNS** records to point the Buscarron domain to the Matrix server.
|
|
|
|
By default, you will need to create a CNAME record for `buscarron`. See [Configuring DNS](configuring-dns.md) for details about DNS changes.
|
|
|
|
If you've decided to reuse the `matrix.` domain, you won't need to do any extra DNS configuration.
|
|
|
|
## Installing
|
|
|
|
After configuring the playbook and potentially [adjusting your DNS records](#adjusting-dns-records), run the playbook with [playbook tags](playbook-tags.md) as below:
|
|
|
|
<!-- NOTE: let this conservative command run (instead of install-all) to make it clear that failure of the command means something is clearly broken. -->
|
|
```sh
|
|
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,ensure-matrix-users-created,start
|
|
```
|
|
|
|
**Notes**:
|
|
|
|
- The `ensure-matrix-users-created` playbook tag makes the playbook automatically create the bot's user account.
|
|
|
|
- The shortcut commands with the [`just` program](just.md) are also available: `just install-all` or `just setup-all`
|
|
|
|
`just install-all` is useful for maintaining your setup quickly ([2x-5x faster](../CHANGELOG.md#2x-5x-performance-improvements-in-playbook-runtime) than `just setup-all`) when its components remain unchanged. If you adjust your `vars.yml` to remove other components, you'd need to run `just setup-all`, or these components will still remain installed.
|
|
|
|
- If you change the bot password (`matrix_bot_buscarron_password` in your `vars.yml` file) subsequently, the bot user's credentials on the homeserver won't be updated automatically. If you'd like to change the bot user's password, use a tool like [synapse-admin](configuring-playbook-synapse-admin.md) to change it, and then update `matrix_bot_buscarron_password` to let the bot know its new password.
|
|
|
|
## Usage
|
|
|
|
To use the bot, invite it to the room you specified on your `vars.yml` file (`/invite @bot.buscarron:example.com` where `example.com` is your base domain, not the `matrix.` domain).
|
|
|
|
After the bot joins the room, anyone can call the web form via HTTP POST method.
|
|
|
|
Here is an example for the `contact` form:
|
|
|
|
```html
|
|
<form method="POST" action="https://buscarron.example.com/contact">
|
|
<!--your fields-->
|
|
</form>
|
|
```
|
|
|
|
**Note**: to fight against spam, Buscarron is **very aggressive when it comes to banning** and will ban you if:
|
|
|
|
- you hit the homepage (HTTP `GET` request to `/`)
|
|
- you submit a form to the wrong URL (`POST` request to `/non-existing-form`)
|
|
- `hasemail` is enabled for the form (like in the example above) and you don't submit an `email` field
|
|
|
|
If you get banned, you'd need to restart the process by running the playbook with `--tags=start` or running `systemctl restart matrix-bot-buscarron` on the server.
