*Since Camel {since}*

*{component-header}*

The AWS2 EKS component supports create, delete, describe and list clusters
https://aws.amazon.com/eks/[AWS EKS] clusters instances.

Prerequisites

You must have a valid Amazon Web Services developer account, and be
signed up to use Amazon EKS. More information is available at
https://aws.amazon.com/eks/[Amazon EKS].


== URI Format

-------------------------
aws2-eks://label[?options]
-------------------------

You can append query options to the URI in the following format,
?options=value&option2=value&...


// component-configure options: START

// component-configure options: END

// component options: START
include::partial$component-configure-options.adoc[]
include::partial$component-endpoint-options.adoc[]
// component options: END

// endpoint options: START

// endpoint options: END


Required EKS component options

You have to provide the amazonEKSClient in the
Registry or your accessKey and secretKey to access
the https://aws.amazon.com/eks/[Amazon EKS] service.

== Usage

=== Static credentials vs Default Credential Provider

You have the possibility of avoiding the usage of explicit static credentials, by specifying the useDefaultCredentialsProvider option and set it to true.

 - Java system properties - aws.accessKeyId and aws.secretKey
 - Environment variables - AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY.
 - Web Identity Token from AWS STS.
 - The shared credentials and config files.
 - Amazon ECS container credentials - loaded from the Amazon ECS if the environment variable AWS_CONTAINER_CREDENTIALS_RELATIVE_URI is set.
 - Amazon EC2 Instance profile credentials. 

For more information about this you can look at https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/credentials.html[AWS credentials documentation]

include::partial$component-endpoint-headers.adoc[]
// component headers: END

=== EKS Producer operations

Camel-AWS EKS component provides the following operation on the producer side:

- listClusters
- createCluster
- describeCluster
- deleteCluster

== Producer Examples

- listClusters: this operation will list the available clusters in EKS

[source,java]
--------------------------------------------------------------------------------
from("direct:listClusters")
    .to("aws2-eks://test?eksClient=#amazonEksClient&operation=listClusters")
--------------------------------------------------------------------------------

== Using a POJO as body

Sometimes build an AWS Request can be complex, because of multiple options. We introduce the possibility to use a POJO as body.
In AWS EKS there are multiple operations you can submit, as an example for List cluster request, you can do something like:

[source,java]
------------------------------------------------------------------------------------------------------
from("direct:start")
  .setBody(ListClustersRequest.builder().maxResults(12).build())
  .to("aws2-eks://test?eksClient=#amazonEksClient&operation=listClusters&pojoRequest=true")
------------------------------------------------------------------------------------------------------

In this way you'll pass the request directly without the need of passing headers and options specifically related to this operation.

== Dependencies

Maven users will need to add the following dependency to their pom.xml.

*pom.xml*

[source,xml]
---------------------------------------
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-aws2-eks</artifactId>
    <version>${camel-version}</version>
</dependency>
---------------------------------------

where `$\{camel-version}` must be replaced by the actual version of Camel.
