Manage IDP

Instructions

Step 1: Establish Scope

Call MCP tool: harness_list
Parameters:
  resource_type: "project"
  org_id: "<organization>"

Step 2: Identify the IDP Task

1. Service Catalog Template -- Standardized microservice template with scaffolding, CI/CD, and observability
2. Self-Service Environment Provisioning -- On-demand environment creation with IaC and RBAC controls
3. Service Documentation -- Generate catalog-info.yaml, API docs, and architecture overviews
4. Architecture Decision Record (ADR) -- Structured decision documentation
5. Developer Onboarding -- Automated Day 1 onboarding workflow

Step 3: Create Service Catalog Template

• Technology stack (Node.js, Java, Python, Go, etc.)
• Service pattern (REST API, gRPC, event-driven, etc.)
• Container registry for Docker images
• Observability stack (Datadog, Prometheus, etc.)

1. Application scaffolding with standard dependencies
2. CI pipeline: build, test, security scan, Docker build and push
3. CD pipeline: deploy to dev, staging, production with approvals
4. Observability: health endpoints, metrics, structured logging, dashboards
5. catalog-info.yaml with ownership metadata and SLO links

Call MCP tool: harness_create
Parameters:
  resource_type: "template"
  org_id: "<organization>"
  project_id: "<project>"
  body:
    name: "<stack>-microservice-template"
    identifier: "<stack>_microservice_template"
    versionLabel: "1.0.0"
    type: "Pipeline"
    yaml: |
      template:
        name: <stack>-microservice-template
        identifier: <stack>_microservice_template
        versionLabel: "1.0.0"
        type: Pipeline
        spec:
          stages:
            - stage:
                name: Build
                type: CI
                spec:
                  # Build, test, scan, push
            - stage:
                name: Deploy Dev
                type: Deployment
                spec:
                  # Deploy to dev environment

Step 4: Create Self-Service Environment Provisioning

• Environment type (dev, staging, QA, ephemeral)
• Cloud provider and IaC tool (Terraform, Pulumi, CloudFormation)
• Max concurrent environments per developer
• TTL for ephemeral environments

• Pre-approved infrastructure modules
• Database provisioning with test data seeding
• Secret injection from Harness Secrets or Vault
• RBAC: developer can create/destroy own environments
• Cost controls: TTL-based auto-cleanup, budget caps

Step 5: Generate Service Documentation

• Service name, team, type (backend, frontend, data pipeline)
• Tech stack, repo URL, environments
• API endpoints and dependencies

1. catalog-info.yaml -- Backstage-compatible service registration
2. API documentation -- Endpoint inventory with request/response schemas
3. Architecture overview -- Component diagram, data flow, dependencies
4. Operational guide -- Deployment, monitoring, incident response links

Step 6: Create Architecture Decision Record (ADR)

• Decision title and context
• Options considered with pros/cons
• Decision made and rationale
• Consequences and follow-up actions

• Status (Proposed, Accepted, Deprecated, Superseded)
• Context, Decision, Consequences sections
• Link to related ADRs if applicable

Step 7: Design Developer Onboarding Workflow

• New engineer's role, team, and tech stack
• Required access (repos, environments, tools)
• Mentorship and buddy program details

• Access provisioning (GitHub org, Harness project, cloud accounts)
• CDE setup with pre-configured workspace
• First task assignment with guided walkthrough
• Week 1 and Week 2 milestone checklists

Examples

• "Create a microservice template for our Node.js services" -- Generate service catalog template with CI/CD, observability, and catalog-info.yaml
• "Set up self-service environments for developers" -- Create IDP workflow for on-demand environment provisioning
• "Generate documentation for the checkout-service" -- Create catalog-info.yaml, API docs, and architecture overview
• "Write an ADR for our migration from REST to gRPC" -- Create structured ADR with context, decision, and consequences
• "Design an onboarding workflow for new backend engineers" -- Create Day 1 self-service workflow with access, CDE, and milestones

Performance Notes

• Service catalog templates should be tested end-to-end before publishing -- a broken template degrades developer trust.
• Self-service environments need cost guardrails (TTL, budget caps) to prevent cloud spend overruns.
• catalog-info.yaml must conform to Backstage entity schema -- validate before registering.
• ADRs should reference the IDP portal URL so they are discoverable alongside the service catalog.
• Onboarding workflows should be idempotent -- re-running should not create duplicate resources.

Troubleshooting

Template Not Appearing in Catalog

• Verify the template YAML is valid and the identifier matches the directory name
• Check that the template is published (not draft) and the version label is set
• Confirm the user has read access to the org/project where the template lives

Self-Service Workflow Failing

• Check IaC module permissions -- the service account needs create/destroy access in the target cloud
• Verify secret references are resolvable in the target project scope
• Check TTL cleanup jobs are not conflicting with active environments

Documentation Out of Date

• Regenerate catalog-info.yaml when ownership or dependencies change
• Link API docs to the CI pipeline so they auto-update on merge
