## Prod
A `docker-compose.yml` is provided:
- Use [Traefik](https://traefik.io/) on the `web` docker network, eg. with
[proxyta.net](https://framagit.org/oxyta.net/proxyta.net)
- Put the configuration into a `.env` file
- Configure your DNS for `${CHATONS_SERVICE:-matrixwebhook}.${CHATONS_DOMAIN:-localhost}`
```
docker-compose up -d
```
## Test / Usage
```
curl -d '{"body":"new contrib from toto: [44](http://radio.localhost/map/#44)", "key": "secret"}' \
'http://matrixwebhook.localhost/!DPrUlnwOhBEfYwsDLh:matrix.org'
```
(or localhost:4785 without docker)
### Formatters
These formatters will output custom messages depending on the specific formatter. Generally to set these up, on the remote provider you would create a webhook with `https://your.webhook.domain/?formatter=<formatter columun below>&api_key=<your apikey>`
| formatter | description | key location |
| -- | - | - |
| github | for github.com | in github JSON webhook settings as `secret` |
| grafana | for grafana | in webhook URL with `api_key=<yourkey>` |
| pingdom | for pingdom.com | in webhook URL with `api_key=<yourkey>` |
| buildbot | buildbot reporter | in webhook URL with `api_key=<yourkey>` or in master.cfg credentials header as `api_key` |
| generic | returns raw JSON that was recieved. For developing additional formatter plugins | in URL with api_key=<yourkey> |
For example, if your matrix-webhook was hosted at https://webhooks.example.com, and you were setting up pingdom and you have an api_key of "123", you would use the following URL for your webhook call from pingdom:
`https://webhooks.example.com/?formatter=pingdom&api_key=123`
### For Gitlab
At a group level, Gitlab does not permit to setup webhooks. A workaround consists to use Google
Chat or Microsoft Teams notification integration with a custom URL (Gitlab does not check if the url begins with the normal url of the service).
#### Google Chat
Add a Google Chat integration with an URL ending with `?formatter=gitlab_gchat&key=API_KEY`
#### Microsoft Teams
Add a Microsoft Teams integration with an URL ending with `?formatter=gitlab_teams&key=API_KEY`
