eksup is a tool to help DevOps Engineers/Platform Engineers/SREs (you name it!) upgrade EKS clusters. With eksup you can list and check for newer versions of addons and Kubernetes versions supported by EKS.

Getting started

• Download the latest release from the releases page and extract the binary.
• Run ./eksup init to create a new config file and then configure it with your AWS credentials or SSO profile name. You can't use both at the same time.

Example config file

# With profile
aws:
  auth:
    profile: true
    profileName: my_sso_profile_name
  region: us-east-1

# With default credentials
aws:
  auth:
    # Use the default credentials
    credentials: true
  region: us-east-1

What does it do?

Listing addons

$ eksup addons list

Listing installed add-ons for cluster: my-cluster
coredns
kube-proxy
vpc-cni

Check for newer addons versions

$ eksup addons check

Listing add-ons for cluster: my-cluster
coredns is running version: v1.9.3-eksbuild.2 and can be upgraded to version: v1.9.3-eksbuild.5
kube-proxy is running version: v1.24.9-eksbuild.1 and can be upgraded to version: v1.24.10-eksbuild.2
vpc-cni is running version: v1.12.5-eksbuild.1 and can be upgraded to version: v1.13.0-eksbuild.1

List EKS clusters

$ eksup addons check

List of clusters:
my-cluster
my-cluster-02

Check for newer Kubernetes versions

$ eksup addons check

What it does not do

Currently, eksup does not support any upgrade operations. It only lists the available versions for addons and Kubernetes.
