  --file ./data.json --name data.json

az storage blob download \
  --account-name mystorageacct \
  --container-name mycontainer \
  --name data.json --file ./downloaded.json

# List blobs
az storage blob list \
  --account-name mystorageacct \
  --container-name mycontainer -o table

# Generate SAS token
az storage blob generate-sas \
  --account-name mystorageacct \
  --container-name mycontainer \
  --name data.json \
  --permissions r --expiry 2024-12-31

Azure Functions

# Create Function App
az functionapp create \
  --resource-group my-rg \
  --name my-func-app \
  --consumption-plan-location eastus \
  --runtime python --runtime-version 3.11 \
  --functions-version 4 \
  --storage-account mystorageacct \
  --os-type Linux

# Deploy function code
func azure functionapp publish my-func-app

# App settings
az functionapp config appsettings set \
  --name my-func-app -g my-rg \
  --settings "DB_HOST=mydb.postgres.database.azure.com" "ENV=production"

# View logs
az functionapp log tail --name my-func-app -g my-rg

AKS (Kubernetes)

# Create AKS cluster
az aks create \
  --resource-group my-rg \
  --name my-aks \
  --node-count 3 \
  --node-vm-size Standard_DS2_v2 \
  --enable-managed-identity \
  --generate-ssh-keys

# Get credentials
az aks get-credentials -g my-rg -n my-aks

# Scale node pool
az aks scale -g my-rg -n my-aks --node-count 5

# Enable autoscaler
az aks update -g my-rg -n my-aks \
  --enable-cluster-autoscaler --min-count 1 --max-count 10

Networking

# Create VNet and subnet
az network vnet create \
  --resource-group my-rg \
  --name my-vnet \
  --address-prefix 10.0.0.0/16 \
  --subnet-name default --subnet-prefix 10.0.1.0/24

# Network Security Group
az network nsg create -g my-rg -n my-nsg
az network nsg rule create -g my-rg --nsg-name my-nsg \
  -n allow-https --priority 100 \
  --destination-port-ranges 443 --access Allow --protocol Tcp

Useful Patterns

# Query with JMESPath
az vm list -g my-rg --query "[?powerState=='VM running'].name" -o tsv

# Export ARM template from existing resources
az group export -g my-rg > template.json

# Cost analysis
az consumption usage list --start-date 2024-01-01 --end-date 2024-01-31

# Monitor and alerts
az monitor metrics list --resource /subscriptions/.../my-vm \
  --metric "Percentage CPU" --interval PT1H
