EksX

AWS EKS utility library born out of a need to replicate the following functionality, but without relying on the command line:

https://awscli.amazonaws.com/v2/documentation/api/latest/reference/eks/get-token.html

Heavily inspired from the wonderful answer I found on this topic here:

https://stackoverflow.com/questions/59853623/get-authentication-token-from-aws-eks-using-the-aws-java-sdk-v2

Example Gradle usage:

repositories {
    mavenCentral()
}
dependencies {
    implementation("dev.mrbergin:eksx:0.0.1")
}

Example Usage:

val eksx = AwsEksX(
    accessKeyId = yourAccessKeyId,
    secretAccessKey = yourSecretAccessKey,
    region = yourRegion,
)

val token = eksx.getToken(
    clusterName = yourClusterName,
    roleArn = yourRoleArn, //optional
)

//use the token with your favourite K8s client!

You have no tests, what kind of dev are you?!

I found the effort to value ratio unappealing. The logic in this code is mostly just stitching together a bunch of AWS APIs, and the unit tests I started writing were a monstrosity of white box testing mocks which I'm not a fan of...

I wanted to write some integration tests with docker and localstack, but it appears EKS is only available with the pro version of localstack, so I just decided to write examples and test them against a real EKS cluster instead.

PRs that educate me on how this could actually be unit / integration tested are welcome!
