AWS (Amazon Web Services)

AWS CLI Setup

# Install
curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip && sudo ./aws/install

# Configure
aws configure
# Enter: Access Key ID, Secret Access Key, Region, Output format

EC2 Instances

# List instances
aws ec2 describe-instances --query 'Reservations[].Instances[].[InstanceId,State.Name,Tags[?Key==`Name`].Value|[0]]' --output table

# Start/Stop instance
aws ec2 start-instances --instance-ids i-1234567890abcdef0
aws ec2 stop-instances --instance-ids i-1234567890abcdef0

# Create instance
aws ec2 run-instances --image-id ami-12345678 --instance-type t2.micro --key-name MyKey

# SSH to instance
ssh -i "key.pem" [email protected]

S3 Storage

# List buckets
aws s3 ls

# Upload/download
aws s3 cp file.txt s3://my-bucket/
aws s3 cp s3://my-bucket/file.txt ./
aws s3 sync ./folder s3://my-bucket/folder

# Create bucket
aws s3 mb s3://my-new-bucket

Lambda Functions

# List functions
aws lambda list-functions

# Invoke function
aws lambda invoke --function-name MyFunction --payload '{"key": "value"}' output.json

# Deploy (zip)
zip -r function.zip .
aws lambda update-function-code --function-name MyFunction --zip-file fileb://function.zip

Azure

Azure CLI Setup

# Install
curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash

# Login
az login

# Set subscription
az account set --subscription "Subscription Name"

Virtual Machines

Compute Engine

# List instances
gcloud compute instances list

# Start/Stop
gcloud compute instances start INSTANCE_NAME --zone=ZONE
gcloud compute instances stop INSTANCE_NAME --zone=ZONE

# Create instance
gcloud compute instances create my-instance --zone=us-central1-a --machine-type=e2-micro

# SSH
gcloud compute ssh INSTANCE_NAME --zone=ZONE

Cloud Storage

# List buckets
gsutil ls

# Upload/download
gsutil cp file.txt gs://my-bucket/
gsutil cp gs://my-bucket/file.txt ./
gsutil -m rsync -r ./folder gs://my-bucket/folder

# Create bucket
gsutil mb gs://my-new-bucket

Cloud Functions

# Deploy function
gcloud functions deploy my-function --runtime python39 --trigger-http --allow-unauthenticated

# Invoke
gcloud functions call my-function --data '{"name": "World"}'

Terraform (Infrastructure as Code)

Basic Terraform

# main.tf
provider "aws" {
  region = "us-east-1"
}

resource "aws_instance" "example" {
  ami           = "ami-0c55b159cbfafe1f0"
  instance_type = "t2.micro"
  
  tags = {
    Name = "FRIDAY-Instance"
  }
}

Terraform Commands

# Initialize
terraform init

# Plan
terraform plan

# Apply
terraform apply

# Destroy
terraform destroy

# Show state
terraform show

Docker & Container Registries

# Build and push to AWS ECR
aws ecr get-login-password | docker login --username AWS --password-stdin $ECR_URL
docker build -t my-app .
docker tag my-app:latest $ECR_URL/my-app:latest
docker push $ECR_URL/my-app:latest

# Azure Container Registry
az acr login --name myregistry
docker tag my-app myregistry.azurecr.io/my-app:latest
docker push myregistry.azurecr.io/my-app:latest

# Google Container Registry
gcloud auth configure-docker
docker tag my-app gcr.io/my-project/my-app:latest
