Telegram bot to do things

telgram-chatops

A Telegram bot to send pipeline updates from CodePipeline to a Telegram chat

Building

Run the following

$ make build

This will produce a Lambda in the build/ directory

Deploying

Set the following environment variables:

• CLOUDFORMATION_BUCKET - The Cloudformation artifact bucket
• TELEGRAM_TOKEN - The API token give to you by the Botfather
• TELEGRAM_CHAT_ID - ID of the chat to post updates to

Then run

$ make deploy

This will deploy the function and an SNS topic. After this, configure CodePipeline to send events to the topic

$ aws codestar-notifications create-notifications-rule --cli-input-json  file://rule.json

Where rule.json takes the form of:

{
  "Name": "CodePipeline",
  "EventTypeIds": [
    "codepipeline-pipeline-pipeline-execution-started"
  ],
  "Resource": "{Pipeline ARN}",
  "Targets": [
        {
          "TargetType": "SNS",
          "TargetAddress": "{SNS Topic ARN}"
        }
    ],
    "Status": "ENABLED",
    "DetailType": "FULL"
}

EventTypeIds can be any combination of the following

• codepipeline-pipeline-action-execution-succeeded
• codepipeline-pipeline-action-execution-failed
• codepipeline-pipeline-stage-execution-started
• codepipeline-pipeline-pipeline-execution-failed
• codepipeline-pipeline-manual-approval-failed
• codepipeline-pipeline-pipeline-execution-canceled
• codepipeline-pipeline-action-execution-canceled
• codepipeline-pipeline-pipeline-execution-started
• codepipeline-pipeline-stage-execution-succeeded
• codepipeline-pipeline-manual-approval-needed
• codepipeline-pipeline-stage-execution-resumed
• codepipeline-pipeline-pipeline-execution-resumed
• codepipeline-pipeline-stage-execution-canceled
• codepipeline-pipeline-action-execution-started
• codepipeline-pipeline-manual-approval-succeeded
• codepipeline-pipeline-pipeline-execution-succeeded
• codepipeline-pipeline-stage-execution-failed
• codepipeline-pipeline-pipeline-execution-superseded

Troubleshooting

SNS Topic not receiving messages

In this case the pipeline's IAM role may not have permission to publish messages to the topic. Add a policy to allow the pipeline to publish SNS messages

Todo

• Add webhooks so the bot can answer questions about pipeline statuses
  • List pipelines
  • Get pipeline statuses
  • Start pipeline execution
  • Get pipeline details
• Add webhooks to subscribe and unsubscribe via the bot itself rather than futzing with AWS
