# Supported Kubernetes versions
<a name="supported_kubernetes_version"></a>

AWS Batch on Amazon EKS currently supports the following Kubernetes versions:
+ `1.34`
+ `1.33`
+ `1.32`
+ `1.31`
+ `1.30`
+ `1.29`

You might see an error message that resembles the following when you use the `CreateComputeEnvironment` API operation or `UpdateComputeEnvironment`API operation to create or update a compute environment. This issue occurs if you specify an unsupported Kubernetes version in `EC2Configuration`.

```
At least one imageKubernetesVersion in EC2Configuration is not supported.
```

To resolve this issue, delete the compute environment and then re-create it with a supported Kubernetes version. 

You can perform a minor version upgrade on your Amazon EKS cluster. For example, you can upgrade the cluster from `1.xx` to `1.yy` even if the minor version isn't supported. 

However, the compute environment status might change to `INVALID` after a major version update. For example, if you perform a major version upgrade from `1.xx` to `2.yy`. If the major version isn't supported by AWS Batch, you see an error message that resembles the following.

```
reason=CLIENT_ERROR - ... EKS Cluster version [2.yy] is unsupported
```
