# Validator Management

This section covers creating a validator, and the operational tasks that go beyond viewing its health: managing parties, protecting keys, adding optional components, & keeping a validator upgradable &

## How change reaches a validator

Worth internalising before you operate one, because it determines where you go to change things.

<table><thead><tr><th width="270">To change...</th><th>Do this</th></tr></thead><tbody><tr><td>Component versions, resources, database, authentication, optional components, KMS</td><td>Edit the <code>Validator</code> resource and re-apply. The operator reconciles the change.</td></tr><tr><td>Parties, ledger users, wallet users, DAR packages</td><td>Use the UI, or the REST API. These are ledger operations, not configuration.</td></tr><tr><td>Platform-wide settings — hostnames, TLS, the identity provider the UI uses, Grafana links</td><td>Change the Helm values and upgrade the release.</td></tr><tr><td>Anything Canton supports that CatalyX does not surface</td><td>Use the <a href="/catalyx-blockchain-manager/canton-network/version-2.0/console-guide-canton/canton-console.md">Canton console</a>.</td></tr></tbody></table>

{% hint style="info" %}
Editing a `Validator` is a normal Kubernetes update — `kubectl apply`, `kubectl edit`, or a GitOps commit. Watch the **Observed Generation** on the validator's [Status](/catalyx-blockchain-manager/canton-network/version-2.0/console-guide-canton/validators/status-and-specification.md) tab to confirm your change was picked up.

## 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, and the optional `goal` query parameter:

```
GET https://docs.catalyx.solutions/catalyx-blockchain-manager/canton-network/version-2.0/validator-management.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
