Skaffold Standards

Skaffold Standards

When to Use This Skill

Version: 2025.1

Standard Skaffold configuration for local Kubernetes development workflows using OrbStack and dotenvx.

Standard Configuration

API Version

apiVersion: skaffold/v4beta13
kind: Config

Always use the latest stable API version. Currently: skaffold/v4beta13

Build Configuration

build:
  local:
    push: false           # Never push to registry for local dev
    useDockerCLI: true    # Use Docker CLI (better caching)
    useBuildkit: true     # Enable BuildKit for performance
    concurrency: 0        # Unlimited parallel builds
  # Generate secrets from encrypted .env files before building
  hooks:
    before:
      - command: ['sh', '-c', 'dotenvx run -- sh scripts/generate-secrets.sh']
        os: [darwin, linux]
  artifacts:
    - image: app-name
      context: .
      docker:
        dockerfile: Dockerfile
    # Optional: init container for database migrations
    - image: app-db-init
      context: .
      docker:
        dockerfile: Dockerfile.db-init

Port Forwarding (Security)

IMPORTANT: Always bind to localhost only:

portForward:
  - resourceType: service
    resourceName: app-name
    port: 80
    localPort: 8080
    address: 127.0.0.1    # REQUIRED: Bind to localhost only

Never use 0.0.0.0 or omit the address field.

Deploy Configuration

deploy:
  kubeContext: orbstack  # OrbStack for local development
  kubectl:
    defaultNamespace: app-name
    # Optional: validation before deploy
    hooks:
      before:
        - host:
            command: ["sh", "-c", "echo 'Deploying...'"]
            os: [darwin, linux]
  statusCheck: true
  # Extended timeout for init containers (db migrations, seeding)
  statusCheckDeadlineSeconds: 180
  tolerateFailuresUntilDeadline: true
  # Parse JSON logs from applications for cleaner output
  logs:
    jsonParse:
      fields: ["message", "level", "timestamp"]

Standard Profiles

Profile: db-only

Database only - for running app dev server locally with hot-reload:

profiles:
  - name: db-only
    build:
      artifacts: []  # Don't build app
    manifests:
      rawYaml:
        - k8s/namespace.yaml
        - k8s/postgresql-secret.yaml
        - k8s/postgresql-configmap.yaml
        - k8s/postgresql-service.yaml
        - k8s/postgresql-statefulset.yaml
    portForward:
      - resourceType: service
        resourceName: postgresql
        namespace: app-name
        port: 5432
        localPort: 5435
        address: 127.0.0.1

Use case: Run skaffold dev -p db-only + bun run dev for hot-reload development

Profile: services-only

Backend services only (database, APIs) - use with local frontend dev:

profiles:
  - name: services-only
    build:
      artifacts: []  # Don't build frontend
    manifests:
      rawYaml:
        - k8s/namespace.yaml
        - k8s/database/*.yaml
        - k8s/api/*.yaml
    portForward:
      - resourceType: service
        resourceName: postgresql
        port: 5432
        localPort: 5435
        address: 127.0.0.1

Use case: Run skaffold dev -p services-only + bun run dev for hot-reload frontend

Profile: e2e or e2e-with-prod-data

Full stack for end-to-end testing:

profiles:
  - name: e2e
    manifests:
      rawYaml:
        - k8s/*.yaml  # All manifests

Profile: migration-test

Database migration testing:

profiles:
  - name: migration-test
    manifests:
      rawYaml:
        - k8s/database/*.yaml
    test:
      - image: migration-tester
        custom:
          - command: "run-migrations.sh"

Compliance Requirements

Cluster Context (CRITICAL)

Always specify `kubeContext: orbstack` in deploy configuration. This is the standard local development context.

deploy:
  kubeContext: orbstack
  kubectl: {}

When using Skaffold commands, always include --kube-context=orbstack:

skaffold dev --kube-context=orbstack
skaffold run --kube-context=orbstack
skaffold delete --kube-context=orbstack

Only use a different context if explicitly requested by the user.

Required Elements

Recommended Profiles

Depending on project type:

Project Type Variations

Frontend with Backend Services

# Default: Full stack
manifests:
  rawYaml:
    - k8s/namespace.yaml
    - k8s/frontend/*.yaml
    - k8s/backend/*.yaml
    - k8s/database/*.yaml

profiles:
  - name: services-only
    build:
      artifacts: []
    manifests:
      rawYaml:
        - k8s/namespace.yaml
        - k8s/backend/*.yaml
        - k8s/database/*.yaml

API Service Only

# Simpler configuration
manifests:
  rawYaml:
    - k8s/*.yaml

# No profiles needed for simple services

Infrastructure Testing

Skaffold may not be applicable for pure infrastructure repos. Use Terraform/Helm directly.

dotenvx Integration

Projects use dotenvx for encrypted secrets management in local development.

How It Works

1. Encrypted .env files: .env files contain encrypted values, safe to commit 2. Private key: DOTENV_PRIVATE_KEY decrypts values at runtime 3. Hooks: Skaffold hooks run dotenvx run -- script to inject secrets 4. Generated secrets: Scripts create Kubernetes Secret manifests from .env

Build Hooks with dotenvx

build:
  hooks:
    before:
      - command: ['sh', '-c', 'dotenvx run -- sh scripts/generate-secrets.sh']
        os: [darwin, linux]

Deploy Hooks with dotenvx

deploy:
  kubectl:
    hooks:
      before:
        - host:
            command: ["sh", "-c", "dotenvx run -- sh scripts/generate-secrets.sh"]

Generate Secrets Script

Create scripts/generate-secrets.sh:

#!/bin/bash
# Generate Kubernetes secrets from .env using dotenvx
set -euo pipefail

# Validate required env vars are set
: "${DATABASE_URL:?DATABASE_URL must be set}"
: "${SECRET_KEY:?SECRET_KEY must be set}"

# Generate app secrets manifest
cat > k8s/app-secrets.yaml << EOF
apiVersion: v1
kind: Secret
metadata:
  name: app-secrets
  namespace: app-name
type: Opaque
stringData:
  DATABASE_URL: "${DATABASE_URL}"
  SECRET_KEY: "${SECRET_KEY}"
EOF

echo "Generated k8s/app-secrets.yaml"

dotenvx Setup

# Install dotenvx
curl -sfS https://dotenvx.sh | sh

# Create encrypted .env
dotenvx set DATABASE_URL "postgresql://..."
dotenvx set SECRET_KEY "..."

# Encrypt existing .env
dotenvx encrypt

# Store private key securely (NOT in git)
echo "DOTENV_PRIVATE_KEY=..." >> ~/.zshrc

Build Hooks (Validation)

Pre-build hooks for validation (in addition to dotenvx):

build:
  artifacts:
    - image: app
      hooks:
        before:
          - command: ['bun', 'run', 'check']
            os: [darwin, linux]

Status Levels

Troubleshooting

Pods Not Starting

• Check statusCheckDeadlineSeconds (increase if needed)
• Enable tolerateFailuresUntilDeadline: true
• Review pod logs: kubectl logs -f <pod>

Port Forwarding Issues

• Ensure port is not already in use
• Check service name matches deployment
• Verify address: 127.0.0.1 is set

Build Caching

• Enable BuildKit: useBuildkit: true
• Use Docker CLI: useDockerCLI: true
• Set concurrency: 0 for parallel builds
