# Create a Minerva resource

### Before you begin

* The Minerva domain must exist. It is typically created during DataOS deployment.
* Compute must be available for coordinator and worker workloads.
* Depots must be configured with valid Secrets.
* You need permission to create a Minerva cluster. See [Minerva Cluster: Access control](/references/v1/resources/minerva/access-control.md).

### Write the manifest

Define the coordinator, workers, compute, runtime user, and depots.

Replace the placeholders with values for your environment.

```yaml
version: v1alpha
type: minerva
name: ${MINERVA_CLUSTER_NAME}

tags:
  - minerva
  - ${TAG1}

spec:
  coordinator:
    replicas: ${COORDINATOR_REPLICAS}
    envs:
      JVM__opts: "${COORDINATOR_JVM_OPTS}"
    resources:
      requests:
        cpu: "${COORDINATOR_REQUEST_CPU}"
        memory: "${COORDINATOR_REQUEST_MEMORY}"
      limits:
        cpu: "${COORDINATOR_LIMIT_CPU}"
        memory: "${COORDINATOR_LIMIT_MEMORY}"
  worker:
    replicas: ${WORKER_REPLICAS}
    envs:
      JVM__opts: "${WORKER_JVM_OPTS}"
    resources:
      requests:
        cpu: "${WORKER_REQUEST_CPU}"
        memory: "${WORKER_REQUEST_MEMORY}"
      limits:
        cpu: "${WORKER_LIMIT_CPU}"
        memory: "${WORKER_LIMIT_MEMORY}"
  compute: ${MINERVA_COMPUTE_NAME}
  runAsUser: ${RUN_AS_USER}
  depots:
    - address: ${DEPOT_ADDRESS}
```

Example:

```yaml
version: v1alpha
type: minerva
name: miniature
tags:
  - minerva
spec:
  coordinator:
    replicas: 1
    envs:
      JVM__opts: "--add-opens=java.base/java.nio=ALL-UNNAMED"
    resources:
      requests:
        cpu: "1"
        memory: "1Gi"
      limits:
        cpu: "2"
        memory: "4Gi"
  worker:
    replicas: 1
    envs:
      JVM__opts: "--add-opens=java.base/java.nio=ALL-UNNAMED"
    resources:
      requests:
        cpu: "1"
        memory: "1Gi"
      limits:
        cpu: "2"
        memory: "4Gi"
  compute: universe-compute
  runAsUser: johndoe
  depots:
    - address: dataos://mys3lh?purpose=rw
```

# Agent Instructions
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://v2.dataos.info/references/v1/resources/minerva/create-a-minerva-resource.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.
