upgrade.sh: Om fargate poddene kjører en versjon bak den man oppgraderer fra, feiler oppgradering

[Kielo87]

Eks: Fargate poddene kjører på 1.19, mens EKS skal oppgraderes fra 1.20 til 1.21

$ ./upgrade.sh ... 1.21 ...
...
cb-91f7801fe5fe, InvalidRequestException: Kubelet version of Fargate pods must be updated to match cluster version 1.20 before updating cluster version; Please recycle all offending pod replicas

Command failed with error code 1: /tmp/eks-upgrade/1-21/eksctl upgrade cluster --name julius --version 1.21 --approve
Aborting.

$ k get node -o wide

Workaround
