Day 2

~1 hour Intermediate Hands-on Precision AI Academy

Today's Objective

Create a Linux VM, configure inbound ports, connect via SSH, and understand VM sizing and cost.

Creating a VM with CLI

azure_cli_-_create_vm.txt
AZURE CLI — CREATE VM
az vm create \
  --resource-group myapp-rg \
  --name my-linux-vm \
  --image Ubuntu2204 \
  --size Standard_B1s \
  --admin-username azureuser \
  --generate-ssh-keys

# Open port 80 for web traffic
az vm open-port --resource-group myapp-rg --name my-linux-vm --port 80
az vm open-port --resource-group myapp-rg --name my-linux-vm --port 443

# Get the public IP
az vm show -d -g myapp-rg -n my-linux-vm --query publicIps -o tsv

# SSH in
ssh azureuser@
install_nginx_on_the_vm.txt
INSTALL NGINX ON THE VM
# Once SSH'd in:
sudo apt update && sudo apt install -y nginx
sudo systemctl enable nginx
sudo systemctl start nginx
# Visit the public IP in your browser — you should see the Nginx welcome page
stop/deallocate_when_done.txt
STOP/DEALLOCATE WHEN DONE
# Deallocated = no compute charges (storage still billed)
az vm deallocate --resource-group myapp-rg --name my-linux-vm

# Start again
az vm start --resource-group myapp-rg --name my-linux-vm
Stopped (not deallocated) VMs still incur compute charges in Azure. Always use az vm deallocate, not just stop, when you're done for the day.
