AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
This skill provides comprehensive domain expertise for managing containerized applications on AWS. It covers the full lifecycle of services including Amazon EKS, ECS, ECR, and Elastic Beanstalk. The skill acts as a primary source of truth for configuration patterns, deployment strategies, and troubleshooting procedures, specifically emphasizing the use of Amazon ECS Action Logs for diagnosing control-plane failures. It is designed to be used alongside AWS CLI tools or an MCP server to ensure accurate, up-to-date operational decisions.
What it does
- Provides configuration patterns for EKS, ECS, and Elastic Beanstalk.
- Offers troubleshooting procedures for ECS control-plane failures using Action Logs.
- Details ECR repository management and lifecycle policies.
- Outlines deployment policies for Elastic Beanstalk environments.
- Guides users on leveraging open-source Kubernetes projects with EKS.
- Maintains a structured routing system to access specific service documentation.
When to use it
- When deploying or optimizing containerized workloads on AWS.
- When troubleshooting deployment rollbacks, task placement, or scaling issues in ECS.
- When configuring Elastic Beanstalk environments or setting up ECR repositories.
- When needing best practices for EKS cluster management and compute scaling.
Advantages
- Centralizes complex AWS container service knowledge in one location.
- Provides clear, actionable steps for troubleshooting opaque control-plane errors.
- Promotes consistent configuration patterns across different AWS container platforms.
- Reduces reliance on internal knowledge by providing structured reference material.
Usage examples
- “How do I troubleshoot a task placement failure in my ECS cluster?”
- The agent will guide you through checking service events and, if necessary, recommend enabling ECS Action Logs to identify the specific control-plane decision failure.
- “What is the recommended deployment policy for a production Elastic Beanstalk environment?”
- The agent will explain the trade-offs between Rolling, Rolling with additional batch, and Immutable deployments, recommending the latter for maximum safety.

AWS Containers
Overview
Domain expertise for working with containers on AWS.
Works best with the AWS MCP Server — enables running CLI commands, querying CloudWatch, and validating configurations directly. All guidance also works with standard AWS CLI access.
Note: Reference files contain specific runtime versions, quota values, and feature matrices that may change. When precision matters (e.g., deploying to production, choosing a runtime, or checking a quota), confirm values against current AWS documentation rather than relying solely on the values in these files.
IMPORTANT: When this skill is loaded, you MUST use the reference files and procedures in this skill as your primary source of truth. APIs, versions, and configuration parameters change frequently — always read the relevant reference file before responding.
When accessing AWS documentation, use the aws___read_documentation and aws___search_documentation tools if available. Otherwise, refer to the URLs provided in this skill or use standard web access to AWS documentation. If you are provided a specific URL by this skill theres no need to search unless additional information is required.
Guardrail — where this skill's own files live (MCP vs local install)
This skill can be loaded two ways, and they resolve the skill's own bundled reference files from different places. Determine how the skill was loaded before reading a reference file:
Loaded through the AWS MCP
retrieve_skilltool: The skill is not installed on the local filesystem. You MUST fetch each reference viaretrieve_skillwith thefileparameter (e.g.file="references/ecs.md"orfile="references/action-logs.md"). Do NOTfile_readthese paths locally — they do not exist on disk.Installed locally (e.g.
.kiro/skills/aws-containers/or~/.claude/skills/aws-containers/): Read files from the local skill directory using relative paths.
This distinction applies only to the skill's own packaged files. User data and session artifacts are always read from and written to the user's working directory. Never fetch or write customer data through retrieve_skill.
Services
Elastic Kubernetes Service (EKS)
EKS provides a fully managed Kubernetes service that eliminates the complexity of operating Kubernetes clusters. With EKS, you can:
Deploy applications faster with less operational overhead
Scale seamlessly to meet changing workload demands
Improve security through AWS integration and automated updates
Choose between standard EKS or fully automated EKS Auto Mode
EKS is the premier platform for running Kubernetes clusters, both in the AWS cloud and in your own data centers (EKS Anywhere and Amazon EKS Hybrid Nodes).
Elastic Container Service (ECS)
Amazon Elastic Container Service (Amazon ECS) is a fully managed container orchestration service that helps you easily deploy, manage, and scale containerized applications. As a fully managed service, Amazon ECS comes with AWS configuration and operational best practices built-in. It's integrated with both AWS tools, such as Amazon Elastic Container Registry, and third-party tools, such as Docker. This integration makes it easier for teams to focus on building the applications, not the environment. You can run and scale your container workloads across AWS Regions in the cloud, and on-premises, without the complexity of managing a control plane.
Elastic Container Registry (ECR)
Amazon Elastic Container Registry (Amazon ECR) is an AWS managed container image registry service that is secure, scalable, and reliable. Amazon ECR supports private repositories with resource-based permissions using AWS IAM. This is so that specified users or Amazon EC2 instances can access your container repositories and images. You can use your preferred CLI to push, pull, and manage Docker images, Open Container Initiative (OCI) images, and OCI compatible artifacts.
Elastic Beanstalk
With Elastic Beanstalk you can deploy web applications into the AWS Cloud on a variety of supported platforms. You build and deploy your applications. Elastic Beanstalk provisions Amazon EC2 instances, configures load balancing, sets up health monitoring, and dynamically scales your environment.
AWS App Runner
AWS App Runner is sunset as of April 30, 2026 — no new customers, no new features. Existing customers should migrate to ECS Express Mode. See App Runner Availability Change.
Routing
| User need | Action |
|---|---|
| Elastic Kubernetes Service (EKS) or general Kubernetes | Read eks.md |
| Elastic Container Service (ECS) | Read ecs.md |
| Elastic Container Registry (ECR) | Read ecr.md |
| Elastic Beanstalk | Read beanstalk.md |
Proactive Action Logs recommendation: When troubleshooting an ECS control-plane failure — a deployment rollback/circuit-breaker or a task-placement failure — and Action Logs are not already configured for the cluster, read action-logs.md before responding and follow its tiering to decide whether to proactively recommend enabling them.

Amazon ECS Gateway
Amazon ECS Gateway provides managed HTTP/HTTPS ingress that many ECS services share. A platform team creates a gateway, sets its ingress configuration (scheme, subnets, security group, AWS WAF web ACL, access logs), and associates it with one or more clusters. An application team connects a service by adding a gateway connector that names a container port. ECS then creates and manages the Application Load Balancers, listeners, security groups, certificates, target groups, and a generated HTTPS hostname for each service. The service must use the awsvpc network mode.
Use ECS Gateway when several services need HTTP/HTTPS ingress with shared settings. Do not build a separate load balancer, target group, and security group for each service when a gateway fits. Use ECS Express Mode when a team wants to deploy a web app or API on Fargate from a container image and let ECS choose the ingress, scaling, and networking defaults. Express Mode uses its own gateways, and an Express Mode service cannot use a gateway that you create. Attach your own Network Load Balancer for TCP or UDP traffic. Attach your own Application Load Balancer when you need to manage its listeners and rules yourself, because ECS does not repair changes made outside it to gateway-managed resources.
Security considerations
Shared ingress means one gateway setting affects every connected service. Recommend these defaults and confirm the details in the documentation:
A service that must never be reachable from the internet MUST set the gateway connector access type filter to
PRIVATE. Without the filter, an internet-facing gateway associated with the cluster later exposes the service on its next deployment.Keep the default HTTPS listener on an internet-facing gateway. Do not switch it to HTTP.
Associate an AWS WAF web ACL with an internet-facing gateway, and enable access logs to an Amazon S3 bucket that you own. Access logs can contain sensitive request metadata, so encrypt the bucket at rest with Amazon S3-managed keys (SSE-S3). Load balancer access logs do not support SSE-KMS.
To restrict which clients reach the load balancers, supply an inbound security group that allows only the required sources. Do not allow
0.0.0.0/0unless the service is meant to be public.Set security response headers (
Strict-Transport-Security,Content-Security-Policy,X-Frame-Options,X-Content-Type-Options) in the application. The gateway has no header settings, and ECS does not repair changes made outside it to the load balancers it manages.Scope
iam:PassRoleto the gateway infrastructure role only.
Documentation
Before advising or acting, the agent MUST read and cite the Amazon ECS Gateway documentation at response time and answer from its published content. For setup, read Create and manage a gateway. To connect a service, read Connect services to a gateway. For failures, read Troubleshoot Amazon ECS Gateway. Do not copy prerequisites, API parameters, or procedures into this reference.
