What it does
AWS Containers is an agent skill from aws/agent-toolkit-for-aws, published by the product's own GitHub organization. Builds and deploys containerized workloads on Elastic Kubernetes Service (EKS), Elastic Container Service (ECS), Fargate, and ECR (Elastic Container Registry). Covers general EKS knowledge, Karpenter, AWS Load Balancer Controller and leveraging various open source Kubernetes projects with EKS. Covers general ECS knowledge, task definitions, Fargate services, ECS Exec, ECS Express Mode and ECS Managed Instances. Covers general Elastic Beanstalk knowledge, Elastic Beanstalk configuration and platforms supported by…
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 16 other files, including reference files (for example `references/action-logs.md`, `references/beanstalk-configuration.md` and `references/beanstalk-platforms.md`).
It sits in DevOps & Cloud, covering Container orchestration and Cloud networking. It works with Amazon Web Services, Kubernetes and Model Context Protocol. The repository describes itself as: Official, AWS-supported MCP servers, skills, and plugins to help AI agents build on AWS. The licence is Apache-2.0.

Requirements
- Docker
- Pre-approved tools (allowed-tools): Read
What it can do on your machine
Read from SKILL.md and the folder at commit 188af2f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Read
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
docs.aws.amazon.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
AWS Containers loads about 1.7k tokens when it runs, and up to ~25k if it reads all its reference files. Until then it costs about 240 tokens; SKILL.md has 709 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.
