Configure external traffic for Alluxio Web UI

To allow external traffic on port 19999 for Alluxio on an Azure virtual machine, open the port in the Network Security Group (NSG). The NSG can be attached to the virtual machine’s network interface or subnet.

Note

For more information about Azure setup, see Getting started with Microsoft Azure Platform .

Add an inbound firewall rule in Azure

To expose the TCP port 19999, create a firewall rule.

  1. Navigate to the Azure portal , go to Virtual Machines, and select your virtual machine.

  1. In the left menu, select Networking, then select Network settings.

  1. Navigate to Create port rule, and select Inbound port rule.

Image Alt Text:Azure Portal Create port rule menu with Inbound port rule selected. Choose this option to open port 19999 for the Alluxio Web UI.Create rule

  1. Configure the inbound security rule with the following settings:
  • Source: My IP address
  • Source IP addresses: (auto-populated with your current public IP)
  • Source port ranges: *
  • Destination: Any
  • Destination port ranges: 19999
  • Protocol: TCP
  • Action: Allow
  • Name: allow-alluxio-port
Note Setting Source to My IP address restricts access to port 19999 to your current machine only. Source port ranges remains * because this refers to the client’s ephemeral outbound port, which is always dynamically assigned. If your IP address changes or you need to access the Alluxio Web UI from a different machine, update the source IP in this rule.
  1. After filling in the details, select Add to save the rule.

You can now access the Alluxio Web UI over port 19999.

What you’ve learned and what’s next

You’ve now configured the Azure Network Security Group to allow incoming traffic on port 19999. This firewall rule enables external access to the Alluxio Web UI for monitoring cluster status and storage usage.

Next, you’ll integrate Alluxio with Apache Spark and begin analyzing cached data performance.
