      * Previously, when the Node Tuning Operator (NTO) was configured using PerformanceProfiles it would create an ocp-tuned-one-shot systemd service. The systemd service would run prior to kubelet and blocked execution. The systemd service invokes Podman which uses an NTO image, but when the NTO image was not present Podman still tried to fetch the image and it would fail. With this release, support is added for cluster-wide proxy environment variables defined in `/etc/mco/proxy.env`. Now, Podman pulls NTO images in environments which need to use proxies for out-of-cluster connections. (link:https://issues.redhat.com/browse/OCPBUGS-42061[*OCPBUGS-42061*])

      Hello Team,

       

      After the hard reboot of all nodes due to a power outage,  failure of image pull of NTO preventing "ocp-tuned-one-shot.service" startup result in dependency failure for kubelet and crio services,

      • Customer has proxy configured in their environment. However,  nodes can not start after hard reboot of all nodes as it looks that NTO ignoring cluster wide proxy settings. To resolve NTO image pull issue, customer has to include proxy variable in  /etc/systemd/system.conf manually.
