# Assigning Agents to Kubernetes Nodes for the connectware-agent Helm Chart

## Assigning Agents to Kubernetes Nodes

You can target specific Kubernetes nodes with your agent using the Kubernetes node selector. This can for example be used to select a remote node close to your shop floor.

Kubernetes node selector is a set of one or more labels, that the target Kubernetes node must have, to be eligible to run the agent.

To set these node selector labels, use the `nodeSelector` value inside the agent’s entry in the `protocolMapperAgents` context of your `values.yaml` file.

**Example**

{% code lineNumbers="true" %}

```yaml
protocolMapperAgents:
  - name: bender-robots
    connectwareHost: connectware.cybus # adjust to actual hostname of Connectware
    nodeSelector:
      mycompany.tld/node-location: shopfloor
      mycompany.tld/building: 1a
```

{% endcode %}

## Unsetting protocolMapperAgentDefaults Node Selector Labels

If you used the `nodeSelector` value in the `protocolMapperAgentDefaults` context of your `values.yaml` file, you can unset them for individual agents by setting the value of `nodeSelector` to `{}` inside the agents entry in the `protocolMapperAgents` context of your `values.yaml`.

**Example**

{% code lineNumbers="true" %}

```yaml
protocolMapperAgentDefaults:
  connectwareHost: connectware.cybus # adjust to actual hostname of Connectware
  nodeSelector:
    mycompany.tld/node-location: shopfloor
    mycompany.tld/building: 1a
protocolMapperAgents:
  - name: bender-robots # this agent will use the node selector labels
  - name: welder-robots # this agent will NOT use the node selector labels
    nodeSelector: {}
```

{% endcode %}

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.cybus.io/2-1-2/documentation/agents/agents-in-kubernetes/configuring-agents-with-the-connectware-agent-helm-chart/assigning-agents-to-kubernetes-nodes-for-the-connectware-agent-helm-chart.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
