Functions

func DoAddonsSupportMultiArch

func DoAddonsSupportMultiArch(ctx context.Context, clientSet kubernetes.Interface) (bool, error)

DoAddonsSupportMultiArch checks if the coredns/kubeproxy/awsnode support multi arch nodegroups We know that AWS node requires 1.6.3+ to work, so we check for that. For kube-proxy and CoreDNS, we do not know what version adds support, so we just ensure they contain a node affinity that allows them to be scheduled on ARM64 nodes.

func DoesAWSNodeSupportMultiArch

func DoesAWSNodeSupportMultiArch(ctx context.Context, clientSet kubernetes.Interface) (bool, error)

DoesAWSNodeSupportMultiArch makes sure awsnode supports ARM nodes

func UpdateAWSNode

func UpdateAWSNode(ctx context.Context, input AddonInput, plan bool) (bool, error)

UpdateAWSNode will update the `aws-node` add-on and returns true if an update is available.

func UpdateCoreDNS

func UpdateCoreDNS(ctx context.Context, input AddonInput, plan bool) (bool, error)

UpdateCoreDNS will update the `coredns` add-on and returns true if an update is available

func UpdateKubeProxy

func UpdateKubeProxy(ctx context.Context, input AddonInput, plan bool) (bool, error)

UpdateKubeProxy updates image tag for kube-system:daemonset/kube-proxy based to match ControlPlaneVersion

}

AddonVersionDescriber describes the versions for an addon.
