Gerritbot

A Cisco Spark bot, which notifies you about new review approvals (i.e. +2/+1/-1/-2 etc.) from Gerrit.

How to use:

1. Register a developer account at https://developer.ciscospark.com.
2. Create a new bot and write down its api key.
3. Build and run the bot in direct or SQS mode (cf. below).

$ cargo run -- <arguments>

The bot can run in two modes.

Direct mode

The bot is listening on a specified endpoint for incoming incoming Spark messages. For that, you need to provide the endpoint url to the bot by setting spark.webhook_url in the configuration file. The bot will register the url for you through the Cisco Spask API. Alternatively, you can also register the url yourself at https://developer.ciscospark.com. In that case, do not provide the option spark.webhook_url, since otherwise it will overwrite you manually configured url.

See configuration example file in config-direct.yml in the repository.

Example:

$ cargo run -- --config config-direct.yml

In this setup, the bot is listening for the incoming messages at localhost:8888, where Spark will send the messages to the endpoint https://endpoint.example.org. This is useful to test the bot in a local environment. For an easy way to get a public url connected to a local endpoint cf. https://ngrok.com.

AWS SQS mode

The bot is polling the Cisco Spark messages from an AWS SQS queue provided by the configuration spark.sqs and spark.sqs_region. The url of the queue can be registered in Spark in the same way as in direct mode.

See configuration example file in config-sqs.yml in the repository.

Example:

$ cargo run -- --config-sqs.yml

This is useful, when the bot is running in a private network and does not have a connection to the internet. SQS is playing the role of a gateway between the internet and the internal traffic.

To forward the Spark messages to a SQS use an AWS API Gateway.

Gerrit

To listen to Gerrit messages, you need to have a Gerrit user with stream-api access capabilities. Admins and Non-interactive users should have such.

The state of the bot is stored in the state.json file in the same directory, where the bot is running.

This is my first Rust project. Any constructive criticism is welcome.
