From the author

Configures CI/CD pipelines using AWS CodePipeline, CodeBuild, CodeDeploy, CodeConnections, and CodeArtifact. Covers CodePipeline V2 (triggers, variables, execution modes, cross-account), buildspec.yml (caching, VPC, Docker), CodeDeploy strategies (blue/green, canary, linear), CodeArtifact (private package registries, auth tokens, cross-account), and source connections (GitHub, GitLab, Bitbucket). Applies when CodePipeline, CodeBuild, CodeDeploy, CodeConnections, CodeArtifact, buildspec.yml, appspec.yml, or CI/CD pipeline orchestration is referenced. Does NOT cover: ECS Fargate services or task definitions (use aws-containers), CDK Pipelines or cdk deploy (use aws-cdk), sam deploy (use aws-serverless), Amplify deployments (use aws-amplify), or GitHub Actions/GitLab CI.

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides guidance on configuring and managing end-to-end CI/CD pipelines within the AWS ecosystem. It covers the integration of source control connections, build environments, package management, and deployment strategies. The content focuses on service orchestration, security best practices, and troubleshooting common infrastructure-level failures in build and deployment processes.

What it does

  • Configures CI/CD pipelines using CodePipeline and CodeConnections.
  • Defines build environments and buildspec logic for CodeBuild.
  • Manages private package registries via CodeArtifact.
  • Implements deployment strategies like blue/green, canary, and linear using CodeDeploy.
  • Provides troubleshooting steps for pipeline, build, and deployment failures.
  • Details security configurations for service roles and cross-account access.

When to use it

  • When setting up automated build and deployment pipelines on AWS.
  • When integrating external source providers like GitHub, GitLab, or Bitbucket.
  • When managing private dependencies for build processes.
  • When implementing traffic shifting strategies for application updates.
  • When debugging pipeline stalls or deployment errors.

Advantages

  • Native integration with AWS security and IAM policies.
  • Supports complex deployment patterns like blue/green and canary.
  • Enables secure cross-account artifact management.
  • Provides centralized control over build and deployment phases.

Usage examples

“How do I set up a pipeline that pulls from GitHub and deploys to ECS?”
The agent provides a sequence to create a connection, configure a build stage for container packaging, and set up a deployment stage using blue/green traffic shifting.
“My CodeBuild project is hanging at the download source phase.”
The agent identifies the likely cause as a VPC configuration issue and suggests verifying the presence of a NAT gateway in the private subnets.
“How can I share packages across different AWS accounts?”
The agent explains how to configure CodeArtifact domain policies and use customer-managed KMS keys to enable cross-account access.
“How do I handle a failed deployment in CodeDeploy?”
The agent outlines how to use automated rollback settings or manual commands to stop and revert the deployment.

Documentation by AWS

AWS Deploy (CI/CD)

Works best with the AWS MCP server for running CLI commands and validating configurations directly. All guidance also works with standard AWS CLI.

Critical Warnings

CodeConnections PENDING trap: Connections created via CLI/CloudFormation remain PENDING indefinitely — MUST complete OAuth in the AWS Console. No API-only path exists.

Cross-account triple requirement: Cross-account deploys need ALL THREE: (1) KMS key policy granting target account (use key ID, not alias), (2) S3 bucket policy for target account, (3) cross-account IAM role with trust policy. Missing any one = cryptic Access Denied.

CodeDeploy ApplicationStop uses PREVIOUS revision: Broken stop scripts in a prior deployment block ALL future deploys. Make stop scripts idempotent (exit 0 if service absent). Unblock with --ignore-application-stop-failures.

CodeBuild VPC without NAT: Builds in VPC subnets without NAT gateway hang at DOWNLOAD_SOURCE silently. Private subnets MUST have NAT gateway or VPC endpoints.

CodeConnections IAM: Use codeconnections: prefix for API calls and IAM policy Actions. Resource ARNs must match exactly — new resources use codeconnections prefix, existing resources may use codestar-connections prefix. Specify both in Resource if you have mixed-age resources.

UseConnection is over-permissive: codeconnections:UseConnection grants access to ALL repositories the connection can reach. MUST specify condition keys (codeconnections:FullRepositoryId, codeconnections:ProviderAction, codeconnections:BranchName) to limit CodeBuild to only the required repository.

How These Services Compose

CodeConnections → CodeBuild → CodeDeploy, orchestrated by CodePipeline.

LayerServiceRole
SourceCodeConnectionsAuthenticates to GitHub/GitLab/Bitbucket, delivers code
PackagesCodeArtifactPrivate package registry, dependency caching from public registries
Build/TestCodeBuildCompiles, tests, packages artifacts
DeployCodeDeployDeploys to EC2/ECS/Lambda with traffic shifting strategies
OrchestratorCodePipelineChains stages, manages transitions, approval gates

Default: V2 pipeline type with QUEUED execution mode. Use PARALLEL only when executions are fully independent.

Security

  • MUST store secrets in Secrets Manager or Parameter Store; reference via CodeBuild type: SECRETS_MANAGER — MUST NOT embed in buildspec as PLAINTEXT

  • MUST use customer-managed KMS keys for cross-account artifact encryption (default encryption does not support cross-account)

  • SHOULD scope CodeBuild/CodeDeploy service roles to specific resource ARNs; MUST NOT use * for s3:GetObject or kms:Decrypt

  • MUST use CodeConnections (not personal access tokens) for source connections; OAuth tokens cannot be rotated automatically

  • See CodePipeline security best practices for comprehensive guidance

      and charge a fee for, acceptance of support, warranty, indemnity,

      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
