| 17 | +# Quickstart: Create and SSH into a Linux VM using Azure CLI |
| 18 | + |
| 19 | +In this quickstart tutorial, you will learn how to automate the creation of a Linux virtual machine (VM) and perform a non-interactive SSH connection test using Azure CLI. This guide provides detailed, step-by-step instructions to help you deploy a VM using a valid Ubuntu image (Ubuntu2204) while avoiding common quota issues. |
| 20 | + |
| 21 | +In response to previous errors, the following changes have been made: |
| 22 | +- The Ubuntu image reference has been corrected to use a valid image ("Ubuntu2204"). |
| 23 | +- The deployment region has been updated from "WestUS2" to "centralindia" to help avoid quota issues experienced in the WestUS2 region. |
| 24 | + |
| 25 | +## Create a Resource Group |
| 26 | + |
| 27 | +In this section, we declare the environment variables and create a new resource group for our deployment. We append a random suffix to the resource group name to ensure uniqueness for each run. |
| 28 | + |
| 29 | +```bash |
| 30 | +export RANDOM_SUFFIX=$(openssl rand -hex 3) |
| 31 | +export REGION="centralindia" |
| 32 | +export MY_RESOURCE_GROUP_NAME="MyLinuxResourceGroup${RANDOM_SUFFIX}" |
| 33 | +az group create --name $MY_RESOURCE_GROUP_NAME --location $REGION |
| 34 | +``` |
| 35 | + |
| 36 | +Results: |
| 37 | + |
| 38 | +```JSON |
| 39 | +{ |
| 40 | + "id": "/subscriptions/xxxxx-xxxxx-xxxxx-xxxxx/resourceGroups/MyLinuxResourceGroupabc123", |
| 41 | + "location": "centralindia", |
| 42 | + "managedBy": null, |
| 43 | + "name": "MyLinuxResourceGroupabc123", |
| 44 | + "properties": { |
| 45 | + "provisioningState": "Succeeded" |
| 46 | + }, |
| 47 | + "tags": null, |
| 48 | + "type": "Microsoft.Resources/resourceGroups" |
| 49 | +} |
| 50 | +``` |
| 51 | + |
| 52 | +> The output above confirms that the resource group was created successfully in the centralindia region. Subscription identifiers and resource group names have been redacted for security. |
| 53 | +
|
| 54 | +## Create the Linux Virtual Machine |
| 55 | + |
| 56 | +Next, we create a Linux virtual machine using the valid Ubuntu2204 image. We also generate SSH keys automatically with the --generate-ssh-keys flag if they do not already exist. A random suffix is added to the VM name to ensure uniqueness. Specifying the region as centralindia helps avoid potential core quota issues. |
| 57 | + |
| 58 | +```bash |
| 59 | +export ADMIN_USERNAME="azureuser" |
| 60 | +export MY_VM_NAME="MyLinuxVM${RANDOM_SUFFIX}" |
| 61 | +az vm create --resource-group $MY_RESOURCE_GROUP_NAME --name $MY_VM_NAME --image Ubuntu2204 --admin-username $ADMIN_USERNAME --generate-ssh-keys |
| 62 | +``` |
| 63 | + |
| 64 | +Results: |
| 65 | + |
| 66 | +```JSON |
| 67 | +{ |
| 68 | + "fqdns": "", |
| 69 | + "id": "/subscriptions/xxxxx-xxxxx-xxxxx-xxxxx/resourceGroups/MyLinuxResourceGroupabc123/providers/Microsoft.Compute/virtualMachines/MyLinuxVMabc123", |
| 70 | + "location": "centralindia", |
| 71 | + "name": "MyLinuxVMabc123", |
| 72 | + "powerState": "VM running", |
| 73 | + "privateIpAddress": "10.0.0.4", |
| 74 | + "publicIpAddress": "52.170.12.34" |
| 75 | +} |
| 76 | +``` |
| 77 | + |
| 78 | +> The output shows that the VM deployment was successful using the Ubuntu2204 image and provides details including the public IP address. |
| 79 | +
|
| 80 | +## Obtain the VM's Public IP |
| 81 | + |
| 82 | +After the VM is deployed, we retrieve its public IP address. This IP address will be used to test the SSH connection. |
| 83 | + |
| 84 | +```bash |
| 85 | +export VM_PUBLIC_IP=$(az vm list-ip-addresses --resource-group $MY_RESOURCE_GROUP_NAME --name $MY_VM_NAME --query "[].virtualMachine.network.publicIpAddresses[].ipAddress" -o tsv) |
| 86 | +echo "The VM public IP address is: $VM_PUBLIC_IP" |
| 87 | +``` |
| 88 | + |
| 89 | +Results: |
| 90 | + |
| 91 | +```text |
| 92 | +The VM public IP address is: 52.170.12.34 |
| 93 | +``` |
| 94 | + |
| 95 | +> The command returns the public IP address of the virtual machine. Note that the actual IP address will vary with each deployment. |
| 96 | +
|
| 97 | +## Test SSH Connection to the VM |
| 98 | + |
| 99 | +To ensure the VM is accessible via SSH without launching an interactive session, we run a non-interactive SSH command. This command executes a simple echo command on the VM and uses SSH options to disable strict host key checking and to operate in batch mode. |
| 100 | + |
| 101 | +```bash |
| 102 | +ssh -o BatchMode=yes -o StrictHostKeyChecking=no $ADMIN_USERNAME@$VM_PUBLIC_IP echo "SSH connection successful" |
| 103 | +``` |
| 104 | + |
| 105 | +Results: |
| 106 | + |
| 107 | +```text |
| 108 | +SSH connection successful |
| 109 | +``` |
| 110 | + |
| 111 | +> The output confirms that the SSH connection to the VM is working as expected by printing the confirmation message. |
