Optimize DevOps Requests with Mattermost & Google Calendar Workflow

Transform your Mattermost chat into an intelligent DevOps command center that automatically classifies requests, identifies on-call engineers, and routes tasks to the right team members. This n8n workflow eliminates manual triage and ensures critical DevOps requests never fall through the cracks.

What this workflow does

When team members mention @devops-duty in your Mattermost channel, this automated workflow springs into action:

• Captures the message via Mattermost outgoing webhook
• Uses AI (LLM) to classify requests into 8 specific categories: incident response, resource creation, CI/CD errors, change requests, code approvals, limits/quotas, questions, and other
• Queries Google Calendar to identify the current on-call engineer
• Routes classified requests through intelligent Switch logic
• Posts acknowledgment in Mattermost thread with classification results

Use cases

Perfect for DevOps teams managing production environments, this workflow handles common scenarios like emergency incident reports that get instantly classified and routed to on-call staff, database provisioning requests that trigger automated resource creation, GitHub Actions failures that connect to investigation workflows, and general DevOps questions that reach the right expertise. SaaS operators can extend each category branch with custom sub-workflows—connect incident classifications to AI-powered investigation tools using Kubernetes and Grafana integrations, or link resource requests to infrastructure provisioning playbooks.

Technical details

Built with essential n8n nodes including Webhook for Mattermost integration, Code node for LLM processing, Google Calendar for on-call lookups, and Switch node for intelligent routing logic. Each Switch output creates independent branches ready for custom extensions, making this workflow a powerful foundation for comprehensive DevOps automation. The sticky note documentation ensures easy maintenance and team collaboration.

Streamline your DevOps request management and reduce response times with this intelligent Mattermost and Google Calendar integration.
