# Kubernetes

### Use Kubernetes for deployment and health monitoring.

[Kubernetes](https://kubernetes.io/) (k8s) is a very powerful tool to manage your containerized services. It is very convenient to deploy and upgrade services running in a Docker container in Kubernetes.

k8s will also do the health check and automatically restart the falling node to maximize your uptime.

We heavily rely on k8s in our test environment. With our own experience, we can tell that k8s will for sure reduce your operation cost.

These are the probe configuration we use in our `deployment.yaml`:

```yaml
livenessProbe:
  httpGet:
    path: "/liveness"
    port: 8080
  initialDelaySeconds: 15
  timeoutSeconds: 2
  periodSeconds: 15
  failureThreshold: 5
readinessProbe:
  httpGet:
    path: "/readiness"
    port: 8080
  initialDelaySeconds: 30
  timeoutSeconds: 2
  periodSeconds: 15
  failureThreshold: 5

```

The setup we currently run for the IoTeX testnet is very similar to the one illustrated below:

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://delegates.iotex.io/get-started/advanced/kubernetes.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.
