# gSlack
## Prerequisites
- Have a Google Cloud Platform project with billing & Cloud Build API enabled
- Have access to a user with `Owner` role on the project
- Have `gcloud` SDK and CLI installed on your machine ([quickstart](https://cloud.google.com/sdk/docs/quickstarts))
- Have [`firebase-tools`](https://firebase.google.com/docs/cli/) CLI installed on your machine
## Generate Slack API Token
- Go to [https://.slack.com/apps/new/A0F7YS25R-bots]()
- Enter a name for the bot to post with. (i.e. gcp-alert-service)
- Click `Add bot integration`.
- Wait until the UI displays the `API Token` and copy the string (i.e. xxxx-yyyyyyyyyyyy-zzzzzzzzzzzzzzzzzzzzzzzz)
## Initialize Firebase environment
- Make sure you are logged in with your `firebase` CLI tool.
- Edit `` in [`.firebaserc`](.firebaserc) with your real project ID.
- Run `$ firebase functions:config:set gslack.api_token="xxxx-yyyyyyyyyyyy-zzzzzzzzzzzzzzzzzzzzzzzz"` (Replace with your slack API token)
## Deployment
- Make sure your `gcloud` SDK and CLI environment is authenticated against the requested GCP project with a user that has Owner permissions.
- Run `$ make create-export PROJECT=` - Replace `` with your project ID (Run once on the first deployment).
- Deploy the function, run: `$ yarn deploy` or `$ npm run deploy` from the [functions](functions) dir.
## Firestore configuration
- Navigate to your project's Firestore console.
- Create a new collection named `"gSlack"` in Firestore.
- Add documents to the new collection with the following schema:
| Field Name | Type | Description |
| ------------- | ------------- | ------------- |
| channel | string | The destination slack channel, i.e. `general` or `@username` for private messages |
| disabled | bool | Whether the rule is disabled; disabled rules will not be evaluated by the function |
| test | string | Must be a a valid JS expression that returns a boolean. If it returns true the test passes. e.g. `$.protoPayload.serviceName==='cloudfunctions.googleapis.com'` |
| message | string | Must be a a valid JS string template. It will be evaluated to produce the message. e.g. `This is the logname: ${$.logName}` |
- Each document is a rule that will be evaluted by the function and will be posted to the corresponding slack channel if the evaluated test expression passes as `true`.
- If you want to temporary disable a rule, simply update the `disabled` field to `true`.
## Function Message Payload Example
The information received by the function for the log entry is something like this:
```
