Upgrading EKS 1.23 to 1.24

Using reduced permissions mode, you must manually delete some entries in the AWS CloudFormation template during the EKS 1.23 to 1.24 upgrade.

In Environments, find your enviroment, and click Upgrade.
Click the CloudFormation Stack Update link.
Edit template in designer.
In the CloudFormation template, find and delete all entries --feature-gates=DynamicKubeletConfig=true.

If you use NTP (Network Time Protocol), replace the ProxyData section with the following code:

    ProxyData:
      Value: |
        #!/bin/bash
        set -x
        
        # Create the containerd and sandbox-image systemd directory
        mkdir -p /etc/systemd/system/containerd.service.d
        mkdir -p /etc/systemd/system/sandbox-image.service.d

        #Configure yum to use the proxy
        cloud-init-per instance yum_proxy_config cat << EOF >> /etc/yum.conf
        proxy=$PROXY
        EOF

        #Set the proxy for future processes, and use as an include file
        cloud-init-per instance proxy_config cat << EOF >> /etc/environment
        http_proxy=$PROXY
        https_proxy=$PROXY
        HTTP_PROXY=$PROXY
        HTTPS_PROXY=$PROXY
        no_proxy=$NOPROXY
        NO_PROXY=$NOPROXY
        EOF

        set -a
        source /etc/environment

        #Configure containerd with the proxy
        cloud-init-per instance containerd_proxy_config tee <<EOF /etc/systemd/system/containerd.service.d/http-proxy.conf >/dev/null
        [Service]
        EnvironmentFile=/etc/environment
        EOF

        # Configure sandbox-image with the proxy
        cloud-init-per instance sandbox-image_proxy_config tee <<EOF /etc/systemd/system/sandbox-image.service.d/http-proxy.conf >/dev/null
        [Service]
        EnvironmentFile=/etc/environment
        EOF

        # Configure the kubelet with the proxy
        cloud-init-per instance kubelet_proxy_config tee <<EOF /etc/systemd/system/kubelet.service.d/proxy.conf >/dev/null
        [Service]
        EnvironmentFile=/etc/environment
        EOF

        # Reload the daemon/containerd to reflect proxy configuration at launch of instance
        cloud-init-per instance reload_daemon systemctl daemon-reload
        cloud-init-per instance reload_containerd systemctl restart --now --no-block containerd
