Covers troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.89## How to Use This Skill1011> **IMPORTANT for Agent**: Use the **Category Index** below to locate relevant sections. For categories with line ranges (e.g., `L35-L120`), use `read_file` with the specified lines. For categories with file links (e.g., `[security.md](security.md)`), use `read_file` on the linked reference file1213> **IMPORTANT for Agent**: If `metadata.generated_at` is more than 3 months old, suggest the user pull the latest version from the repository. If `mcp_microsoftdocs` tools are not available, suggest the user install it: [Installation Guide](https://github.com/MicrosoftDocs/mcp/blob/main/README.md)1415This skill requires **network access** to fetch documentation content:16- **Preferred**: Use `mcp_microsoftdocs:microsoft_docs_fetch` with query string `from=learn-agent-skill`. Returns Markdown.17- **Fallback**: Use `fetch_webpage` with query string `from=learn-agent-skill&accept=text/markdown`. Returns Markdown.1819## Category Index2021| Category | Lines | Description |22|----------|-------|-------------|23| Troubleshooting | L36-L42 | Diagnosing ACI issues by viewing logs/events, understanding provisioning/runtime states, and troubleshooting common deployment, startup, and container runtime failures. |24| Best Practices | L43-L47 | Guidance on designing and running ACI workloads reliably: resource sizing, networking, storage, security, scaling, image management, and operational best practices. |25| Decision Making | L48-L53 | Guidance on cost-optimizing ACI with Spot containers and using prediction-based sizing to configure and right-size Azure Container Instances standby pools. |26| Architecture & Design Patterns | L54-L60 | Design patterns for giving ACI containers static inbound/outbound IPs using Application Gateway, firewalls, and NAT Gateway for controlled, predictable network egress/ingress. |27| Limits & Quotas | L61-L68 | ACI limits on CPU/memory (big containers), regional quota checks, standby pool constraints, and networking limits when using virtual networks |28| Security | L69-L83 | Securing Azure Container Instances: TLS/HTTPS setup, image and secret protection, managed identities, RBAC, DNS safety, ACR auth, CMK encryption, and Azure Policy enforcement. |29| Configuration | L84-L116 | Configuring ACI container groups: YAML, env vars, DNS, volumes, probes, GPUs, restart/entrypoint, standby pools, networking, lifecycle, logging, and monitoring. |30| Deployment | L117-L120 | Using GitHub Actions to build, push, and automatically deploy container images to Azure Container Instances, including workflow YAML setup and authentication configuration. |3132### Troubleshooting33| Topic | URL |34|-------|-----|35|
