What does NL mean in ELECTRONICS

A Node Label (NL) is a metadata key-value pair that you can attach to a Compute Engine node. You can use labels to organize and filter your nodes. For example, you could use labels to identify nodes that are running a particular application or that are located in a particular region.

Node Labels provide several benefits, including:

• Organization: You can use labels to organize your nodes into groups, making it easier to manage your infrastructure.
• Filtering: You can use labels to filter your nodes based on specific criteria. This can be useful for tasks such as identifying nodes that are running a particular application or that are located in a particular region.
• Automation: You can use labels to automate tasks such as node provisioning and scaling.

You can create a Node Label using the Google Cloud Platform (GCP) Console, the gcloud command-line tool, or the Compute Engine API.

• GCP Console: In the GCP Console, go to the Compute Engine page, select Node Groups, and then click Edit next to the node group that you want to add a label to. In the Labels section, click Add and then enter the key and value for the label.
• gcloud command-line tool: You can use the gcloud command-line tool to create a Node Label by running the following command:

  gcloud compute node-groups set-node-template NODE_GROUP --node-template NODE_TEMPLATE --label-filter KEY=VALUE

• Compute Engine API: You can use the Compute Engine API to create a Node Label by making a POST request to the following URL:

  https://compute.googleapis.com/compute/v1/projects/PROJECT/zones/ZONE/nodeGroups/NODE_GROUP/setNodeTemplate

  In the request body, include the following JSON object:

  {
  "nodeTemplate": "NODE_TEMPLATE",
  "labels": {
  "KEY": "VALUE"
  }
  }

You can delete a Node Label using the GCP Console, the gcloud command-line tool, or the Compute Engine API.

• GCP Console: In the GCP Console, go to the Compute Engine page, select Node Groups, and then click Edit next to the node group that you want to delete the label from. In the Labels section, click the X next to the label that you want to delete.
• gcloud command-line tool: You can use the gcloud command-line tool to delete a Node Label by running the following command:

  gcloud compute node-groups set-node-template NODE_GROUP --node-template NODE_TEMPLATE --delete-label-filter KEY

• Compute Engine API: You can use the Compute Engine API to delete a Node Label by making a POST request to the following URL:

  https://compute.googleapis.com/compute/v1/projects/PROJECT/zones/ZONE/nodeGroups/NODE_GROUP/setNodeTemplate

  In the request body, include the following JSON object:

  {
  "nodeTemplate": "NODE_TEMPLATE",
  "labels": {
  "KEY": ""
  }
  }
