Installing and Configuring the Mattermost‑Jira Integration

Mattermost is an open‑source messaging platform designed for development teams, offering private‑cloud deployment, scalability, and integration with many DevOps tools such as Jira, Jenkins, GitLab, and Bitbucket.

Jira is a widely used project‑management tool for tracking user stories, bugs, and the full software development lifecycle. Integrating Jira with Mattermost reduces friction by allowing teams to receive and act on Jira notifications without leaving their chat environment.

Installation of the Mattermost Jira plugin

1. Generate a webhook secret for later configuration. 2. In Jira, go to System Settings → Applications → Application Links and add a new link pointing to http://mm.idevops.site . 3. Configure the application link with the following values:

Application Name: Mattermost

Application Type: Generic Application

Consumer Key: mattermost_http_mm_idevops_site

Consumer Name: Mattermost

Public Key: -----BEGIN PUBLIC KEY-----
MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC2mbXCqNvhulHf4Ls7Pi88kcC8
DClduz1Otaf04INVUlPO7c/NyDqV+0N4SbJsf69DFU0zmJ+8owfqeNLINxSoTmOw

og87n+neJaGOnGmoRwIDAQAB
-----END PUBLIC KEY-----

4. In Mattermost, run the command:

/jira install server http://192.168.1.200:8050/

The bot will prompt you to complete the Application Link configuration as described above.

Connecting Mattermost to Jira

In a Mattermost channel, execute:

/jira connect

Authorize the connection on the displayed page.

To verify the setup, run:

/jira info

If the Jira server information appears, the integration is functional.

Configuring Jira Webhook for Notifications

Run the command:

/jira webhook

The bot returns a URL similar to:

http://mm.idevops.site/plugins/jira/webhook?channel=town-square&secret=LeQaZXj7TTvYNgr1HRj7AZKuD4BOBrfb&team=devopsgroup

In Jira, navigate to System Settings → Webhooks → Create Webhook and paste the provided URL.

Creating Jira Issues from Mattermost

Users can create issues without leaving Mattermost by selecting the project, issue type, summary, description, and priority through the plugin UI.

This integration enables ChatOps, allowing teams to manage Jira workflows directly from their messaging channel, improving collaboration and reducing context‑switching.
