## Example

```ts
// S3 bucket containing the agent core
const codeBucket = new s3.Bucket(this, "AgentCode", {
  bucketName: "my-code-bucket",
  removalPolicy: RemovalPolicy.DESTROY, // For demo purposes
});

// the bucket above needs to contain the agent code

const agentRuntimeArtifact = agentcore.AgentRuntimeArtifact.fromS3(
  {
    bucketName: codeBucket.bucketName,
    objectKey: 'deployment_package.zip',
  },
  agentcore.AgentCoreRuntime.PYTHON_3_12,
  ['opentelemetry-instrument', 'main.py']
);

const runtimeInstance = new agentcore.Runtime(this, "MyAgentRuntime", {
  runtimeName: "myAgent",
  agentRuntimeArtifact: agentRuntimeArtifact,
});
```
