The Red5 Pro Node instance image is used for autoscaling node groups. The Stream Manager will scale nodes using this instance image.

Create Red5 Pro Node Instance

• Navigate to the Google Cloud Console.(https://console.cloud.google.com/)
• Go to Compute Engine in the left-hand navigation and click on VM Instances.
• Click the Create Instance button to create a new virtual machine.
• Specify a name for the instance, such as red5pro-node-instance.
• Select the Region and Zone for the instance. For example, us-central1 and us-central1-a.
• Choose the Machine Type, e.g., n2-standard-2 (2 vCPUs, 8 GB RAM).
• In the Boot disk section, select Ubuntu and choose Ubuntu 22.04 LTS as the operating system image and Size values as 8GB.
• In the Service Account section, Select existing account created in the previous steps and defines roles to this account.
• For Firewall rules, select the checkboxes:
  • Allow HTTP traffic.
  • Allow HTTPS traffic.
• Under Advanced options, Select Networking and In the Network interfaces section, select from existing created in the previous step
• In Network service Tier, Select Standard
• Click Create to launch the instance.

Install Red5 Pro on the Instance

• Connect to your instance over ssh as the ubuntu user. Example: ssh -i ssh_private_key.pem ubuntu@1.2.3.4
• Follow the Installing Red5Pro on a Linux Server instructions.
• Make sure that Red5 Pro service is set to auto-start on launch.
• Red5 Pro Clustering does not work without a license. You will need to purchase a Red5 Pro Professional license from Red5 Pro. Add a file named LICENSE.KEY with your Pro license key (16 characters, plus dashes, like: YOUR-LICE-NSEK-EY12) to the root of the Red5 Pro Server installation (/usr/local/red5pro/LICENSE.KEY).

Configure Autoscaling on the Instance

• Edit the file /usr/local/red5pro/conf/autoscale.xml
• Change the active value from false to true. Example: <property name="active" value="true"/>
• Save and close the file
• Example:

    <bean name="config" class="com.red5pro.clustering.autoscale.Configuration" >
        <property name="active" value="true"/>

Remove Unnecessary Webapps and Plugins

To ensure a faster startup time for your server, we suggest deleting any web apps that you will not be using from the /usr/local/red5pro/webapps directory (for example: secondscreen, template, vod, streammanager, inspector). For ease of setup for the Stream Manager, leave a zipped copy of the server distribution on the server. If you are running a custom web app, then you would want to include that on your node servers.

In addition, it is recommended that you remove any plugins (found in the red5pro/plugins directory) that you will not be using, from the following list:

• red5pro-mpegts* — HLS
• red5pro-restreamer* — restreamer
• red5pro-socialpusher* — social media restreaming
• red5pro-client-suppressor* — suppressor
• inspector.jar — inspector

Verify Red5 Pro on Instance

Start the Red5 Pro service

systemctl start red5pro

Once you have started the Red5 Pro Server, you can verify that it is running and available by opening a web browser and navigating to http://<server-ip>:5080, where <server-ip> is the Public address value of your Red5 Pro server.

Create Red5 Pro Node Instance Image

1. Navigate to Compute Engine → Under Storage section → Images and click Create Image.
2. Enter a NAME for the image, For example red5pro-autoscaling-node-image and select the Source Disk of the red5pro node instance.
3. Set Location to Multi-regional and choose Google-managed encryption key.
4. Click Create to finalize the image creation.

Please record Node image name to your checklist for the NODE_IMAGE_NAME parameter, it will be using in API calls to Stream Manager to create node group config.
