# DeleteCertificateAuthority
<a name="API_DeleteCertificateAuthority"></a>

Deletes a certificate authority (CA) from your cluster.

Deleting a certificate authority removes its public certificate from the cluster's trust bundle. You can't delete the certificate authority that's currently signing certificates for the cluster (its `signingStatus` is `IN_USE`) — to remove the outgoing CA, first activate the successor CA with [`ActivateCertificateAuthority`](https://docs.aws.amazon.com/eks/latest/APIReference/API_ActivateCertificateAuthority.html). Amazon EKS also protects a successor CA from deletion in certain cases to keep a valid rotation path — for example, a successor that Amazon EKS appended can't be deleted while it's the only successor on the cluster. This is an asynchronous operation that returns an `update` object.

## Examples
<a name="API_DeleteCertificateAuthority_Examples"></a>

In the following example or examples, the Authorization header contents (`AUTHPARAMS`) must be replaced with an AWS Signature Version 4 signature. For more information about creating these signatures, see [Signature Version 4 Signing Process](https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html) in the *Amazon EKS General Reference*.

You need to learn how to sign HTTP requests only if you intend to manually create them. When you use the [AWS Command Line Interface (AWS CLI)](http://aws.amazon.com/cli/) or one of the [AWS SDKs](http://aws.amazon.com/tools/) to make requests to AWS, these tools automatically sign the requests for you with the access key that you specify when you configure the tools. When you use these tools, you don't need to learn how to sign requests yourself.

### Example
<a name="API_DeleteCertificateAuthority_Example_1"></a>

The following example deletes the trusted certificate authority with the ID `b2c3d4e5-6789-0abc-def0-1234567890ab` from the cluster named `my-cluster`.
