Amazon EKS cluster upgrade is a utility that automates the upgrade process for Amazon EKS clusters.
## Checks post v0.9.0
The pre/post-flight checks are removed in favor of guiding the user to evaluate their clusters with existing tools which handle this better such as **[eksup](https://github.com/clowdhaus/eksup)**. The existing pre/post checks will be replaced with relevant checks specific to the upgrade (based on previous understanding the cluster is eligible for such an upgrade).
### Cluster Upgrade
1. Control plane upgrade - This is handled entirely by AWS once the version upgrade has been requested.
2. Identification of Managed and Self-managed node - The worker nodes are identified as EKS managed and Self-managed to perform upgrade.
3. Managed Node group update - Updates managed node group to the specified version.
4. Self-managed Node group update
- Launch new nodes with upgraded version and wait until they require ready status for next step.
- Mark existing nodes as unschedulable.
- If pod disruption budget (PDB) is present then check for force eviction flag (--force) which is given by user, only then evict the pods or continue with the flow.
## Pre-Requisites
Before running `eksupgrade`, you will need to have permission for both AWS and the Kubernetes cluster itself.
1. Install `eksupgrade` locally:
```sh
python -m pip install eksupgrade
```
2. Ensure you have the necessary AWS permissions; an example policy of required permissions is listed below:
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "iam",
"Effect": "Allow",
"Action": [
"iam:GetRole",
"sts:GetAccessKeyInfo",
"sts:GetCallerIdentity",
"sts:GetSessionToken"
],
"Resource": "*"
},
{
"Sid": "ec2",
"Effect": "Allow",
"Action": [
"autoscaling:CreateLaunchConfiguration",
"autoscaling:Describe*",
"autoscaling:SetDesiredCapacity",
"autoscaling:TerminateInstanceInAutoScalingGroup",
"autoscaling:UpdateAutoScalingGroup",
"ec2:Describe*",
"ssm:*"
],
"Resource": "*"
},
{
"Sid": "eks",
"Effect": "Allow",
"Action": [
"eks:Describe*",
"eks:List*",
"eks:UpdateAddon",
"eks:UpdateClusterVersion",
"eks:UpdateNodegroupVersion"
],
"Resource": "*"
}
]
}
```
3. Update your local kubeconfig to authenticate to the cluster:
```sh
aws eks update-kubeconfig --name <CLUSTER-NAME> --region <REGION>
```
## Usage
To view the arguments and options, run:
```sh
eksupgrade --help
```
```sh
Usage: eksupgrade [OPTIONS] CLUSTER_NAME CLUSTER_VERSION REGION
Run eksupgrade against a target cluster.
