This application allows you to integrate PagerDuty to your Mattermost instance, letting you subscribe your PagerDuty's services on any custom channel to get notified about any update related to your services. Also, allows the user to create or display incidents, watch who is on-call, etc. without moving from the Mattermost window.

Feature summary

PagerDuty to Mattermost notifications: Link your Mattermost channels with the PagerDuty Service you want to track, so you and your team can get notifications about the creation and updates of each incident, with a user-friendly interface that will let you reassign, change priority, add notes, view details and more.

Development environment

Manual installation

• Download the latest repository release.

Run the local development environment

• You need to have installed at least node version 15 and maximum version 18. You can download the latest lts version of node for the required operating system here: https://nodejs.org/es/download/

Install dependencies

• Move to the project directory or execute cd command to the project directory and execute npm install with a terminal to download all dependency libraries.

$ npm install

• Update the environment configuration file. The .env file must be modified or added to set the environment variables, it must be in the root of the repository.

file: .env

PROJECT=mattermost-app-pagerduty
PORT=4002
HOST=http://localhost:4002

Variable definition

• PROJECT: In case of executing the project with Docker using the .build.sh file, this variable will be used for the name of the container
• PORT: Port number on which the PagerDuty integration is listening
• HOST: PagerDuty API usage URL

• Finally, the project must be executed.

$ npm run dev

Or, if you would like to use the Makefile command:

$ make watch

Run the local development environment with Docker

• You need to have Docker installed. You can find the necessary steps to install Docker for the following operating systems:

Ubuntu Mac Windows

• Once you have Docker installed, the next step would be to run the make run-server command to create the API container and expose it locally or on the server, depending on the case required.

$ make run-server

When the container is created correctly, the API will be running at the url http://127.0.0.1:4002. If Mattermost is running on the same machine, run this slash command in Mattermost to install the app:

/apps install http http://127.0.0.1:4002/manifest.json

To stop the container, execute:

$ make stop-server
