Cloud CLI Cheatsheet

Quick Reference

AWS CLI

S3

aws s3 ls
aws s3 cp file.txt s3://my-bucket/
aws s3 sync ./dist s3://my-bucket/ --delete
aws s3 presign s3://my-bucket/file.txt --expires 3600

Lambda

aws lambda list-functions
aws lambda invoke --function-name myfunc out.json
aws lambda update-function-code --function-name myfunc --zip-file fileb://package.zip
aws lambda update-function-configuration --function-name myfunc \
  --environment Variables="{KEY=val}"

ECS / ECR

aws ecr get-login-password | docker login --username AWS \
  --password-stdin <account>.dkr.ecr.<region>.amazonaws.com
docker tag myapp <account>.dkr.ecr.<region>.amazonaws.com/myapp:v1
docker push <account>.dkr.ecr.<region>.amazonaws.com/myapp:v1
aws ecs update-service --cluster c --service s --force-new-deployment

Vercel CLI

vercel                  # Deploy (preview)
vercel --prod           # Deploy to production
vercel env pull .env.local
vercel logs myapp.vercel.app
vercel rollback

Netlify CLI

netlify deploy                    # Preview deploy
netlify deploy --prod             # Production deploy
netlify env:set KEY value
netlify sites:list
netlify dev                       # Local dev with edge functions

Cloudflare Developer Platform (Wrangler)

Workers

npx wrangler init my-worker       # Scaffold
npx wrangler dev                  # Run locally
npx wrangler deploy               # Deploy
npx wrangler tail                 # Stream live logs

wrangler.toml

name = "my-worker"
main = "src/index.ts"
compatibility_date = "2026-06-01"

[[kv_namespaces]]
binding = "KV"
id = "abc123..."

[[d1_databases]]
binding = "DB"
database_name = "my-db"
database_id = "def456..."

[[r2_buckets]]
binding = "BUCKET"
bucket_name = "my-bucket"

Secrets & Env Vars

npx wrangler secret put API_KEY
npx wrangler secret list

# wrangler.toml
[vars]
ENVIRONMENT = "production"

[env.staging.vars]
ENVIRONMENT = "staging"

KV (Key-Value)

npx wrangler kv key put --binding=KV "key" "value"
npx wrangler kv key get --binding=KV "key"
npx wrangler kv key list --binding=KV
npx wrangler kv key delete --binding=KV "key"

D1 (SQLite)

npx wrangler d1 create my-db
npx wrangler d1 execute my-db --local --file=./schema.sql
npx wrangler d1 execute my-db --remote --command="SELECT * FROM users"

R2 (Object Storage)

npx wrangler r2 bucket create my-bucket
npx wrangler r2 object put my-bucket/file.txt --file=./file.txt
npx wrangler r2 object get my-bucket/file.txt
npx wrangler r2 object delete my-bucket/file.txt

Pages

npx wrangler pages deploy ./dist
npx wrangler pages dev ./dist
npx wrangler pages project list

CI/CD (GitHub Actions)

# Vercel
- run: vercel --prod --token=${{ secrets.VERCEL_TOKEN }}

# Netlify
- run: netlify deploy --prod --auth=${{ secrets.NETLIFY_TOKEN }}

# Cloudflare Workers
- run: npx wrangler deploy

# Cloudflare Pages
- run: npx wrangler pages deploy ./dist --project-name my-site

Tips

• Use wrangler tail to stream live Worker logs for production debugging.
• Cloudflare D1 is SQLite-compatible — local with --local, remote with --remote.
• Use wrangler deploy --env for staging/production separation.
• Add --token flags in CI to avoid interactive login.
