Azure Container Instances Skill

This skill provides expert guidance for Azure Container Instances. 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.

How to Use This Skill

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 file

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

This skill requires network access to fetch documentation content:

• Preferred: Use mcp_microsoftdocs:microsoft_docs_fetch with query string from=learn-agent-skill. Returns Markdown.
• Fallback: Use fetch_webpage with query string from=learn-agent-skill&accept=text/markdown. Returns Markdown.

Category	Lines	Description
Troubleshooting	L36-L42	Diagnosing ACI issues using logs/events, understanding provisioning/runtime states, and troubleshooting deployment failures and container startup problems.
Best Practices	L43-L47	Guidance on designing and running ACI workloads reliably: resource sizing, networking, storage, security, scaling, image management, and operational best practices.
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.
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.
Limits & Quotas	L61-L69	ACI limits, quotas, and behaviors: max CPU/memory (Big Containers), per‑region quotas, standby pool limits, VNet constraints, and FAQs on scaling, performance, and resource usage.
Security	L70-L84	Securing Azure Container Instances: TLS/HTTPS setup, secrets and CMK encryption, managed identities/RBAC, secure ACR pulls, DNS reuse protection, and Azure Policy for compliance.
Configuration	L85-L116	Configuring ACI container groups: env vars, DNS, volumes, GPUs, probes, logging/monitoring, standby pools, restarts, entrypoints, updates, and runtime command execution.
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.
