  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads docker-ci-cd automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

Docker CI/CD Skill

GitLab CI

# .gitlab-ci.yml
stages:
  - build
  - scan
  - deploy

variables:
  DOCKER_IMAGE: $CI_REGISTRY_IMAGE:$CI_COMMIT_SHA

build:
  stage: build
  image: docker:24
  services:
    - docker:24-dind
  script:
    - docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY
    - docker build -t $DOCKER_IMAGE .
    - docker push $DOCKER_IMAGE

scan:
  stage: scan
  image:
    name: aquasec/trivy
    entrypoint: [""]
  script:
    - trivy image --exit-code 1 --severity CRITICAL $DOCKER_IMAGE

deploy:
  stage: deploy
  script:
    - ssh deploy@server "docker pull $DOCKER_IMAGE && docker compose up -d"
  only:
    - main

Best Practices

Caching

# GitHub Actions BuildKit cache
cache-from: type=gha
cache-to: type=gha,mode=max

# GitLab cache
cache:
  key: docker-$CI_COMMIT_REF_SLUG
  paths:
    - .docker-cache

Security

# Scan before push
- name: Scan
  run: trivy image --exit-code 1 --severity CRITICAL $IMAGE

# Sign images (cosign)
- name: Sign
  run: cosign sign $IMAGE

Error Handling

Common Errors

ErrorCauseSolution
unauthorizedBad credentialsCheck registry login
rate limitDocker Hub limitsUse authenticated pulls
cache missFirst buildCache will populate

Fallback Strategy

  1. Build without cache if cache corrupted
  2. Use fallback registry if primary down
  3. Deploy previous version on failure

Troubleshooting

Debug Checklist

  • Registry credentials valid?
  • Docker daemon running?
  • Build context correct?
  • Dockerfile present?

azure-prepare

microsoft/azure-skills

Prepare azd-based Azure projects for deployment: generates azure.yaml, infrastructure (Bicep/Terraform), and Dockerfiles for the Azure Developer CLI (azd) workflow. USE ONLY when the user explicitly wants to use azd as the deployment tool, or the project already has an azure.yaml file. DO NOT USE FOR: non-azd deployments, Python App Service code-only deploys (use python-appservice-deploy), or cross-cloud migration (use azure-cloud-migrate). WHEN: prepare app for azd, create azure.yaml, set up azd infrastructure, modernize app for Azure with azd, deploy with azd, function app, timer trigger, service bus trigger, event-driven function, managed identity, generate Bicep, generate Terraform, create and deploy to Azure.

azure-deploy

microsoft/azure-skills

Execute Azure deployments for ALREADY-PREPARED applications that have existing .azure/deployment-plan.md and infrastructure files. DO NOT use this skill when the user asks to CREATE a new application — use azure-prepare instead. This skill runs azd up, azd deploy, terraform apply, and az deployment commands with built-in error recovery. Requires .azure/deployment-plan.md from azure-prepare and validated status from azure-validate. WHEN: "run azd up", "run azd deploy", "execute deployment", "push to production", "push to cloud", "go live", "ship it", "bicep deploy", "terraform apply", "publish to Azure", "launch on Azure". DO NOT USE WHEN: "create and deploy", "build and deploy", "create a new app", "set up infrastructure", "create and deploy to Azure using Terraform" — use azure-prepare for these.
