Kubernetes → Get All Kubernetes Config Maps Count

AI-generated

Overview

This node operation retrieves the total count of all Kubernetes Config Maps within a specified environment. It is useful for scenarios where you need to monitor or audit the number of Config Maps deployed in a Kubernetes cluster, such as tracking resource usage, validating deployment states, or integrating with dashboards that display cluster configuration metrics.

For example, a DevOps engineer might use this node to quickly get the count of Config Maps before performing cleanup operations or to verify that automated deployment scripts have created the expected number of Config Maps.

Properties

Name Meaning
Id Environment identifier (a required numeric value) specifying which Kubernetes environment to query for Config Maps count.

Output

The output JSON contains the count of all Kubernetes Config Maps found in the specified environment. The structure typically includes a numeric field representing this count. No binary data output is involved.

Example output snippet:

{
  "count": 42
}

Dependencies

  • Requires access to a Kubernetes environment identified by the provided environment ID.
  • The node likely depends on an API or service that interfaces with Kubernetes clusters; thus, appropriate credentials and network access must be configured in n8n.
  • No explicit external libraries or environment variables are indicated in the provided source code snippet.

Troubleshooting

  • Common issues:

    • Invalid or missing environment identifier may cause the node to fail or return zero results.
    • Network connectivity problems between n8n and the Kubernetes API endpoint can lead to timeouts or errors.
    • Insufficient permissions in the Kubernetes cluster to list Config Maps will result in authorization errors.

  • Error messages:

    • Errors related to authentication or authorization usually indicate misconfigured credentials or insufficient RBAC permissions.
    • Timeout or connection refused errors suggest network or endpoint configuration issues.

  • Resolutions:

    • Verify the environment ID is correct and corresponds to a reachable Kubernetes cluster.
    • Ensure the API credentials used have permission to list Config Maps.
    • Check network settings and firewall rules to allow communication with the Kubernetes API server.
