OCPNODE-3719: Default Enablement of Auto Sizing Reserved in OpenShift 4.21 #5390

ngopalak-redhat · 2025-11-04T02:49:07Z

- What I did
This PR updates the default cluster configuration to enable Auto Sizing Reserved for all new OpenShift clusters created from version 4.21 onward.

New Cluster Default: New 4.21 clusters will now have Auto Sizing Reserved enabled by default

Upgrade Preservation:

Clusters originally created before 4.21 will not be impacted by this default change. The prior behavior (disabled) is maintained unless one of the following occurs:

The MachineConfig introduced by the corresponding 4.20 patch is removed.
The user creates a custom KubeletConfig to explicitly override the default.

If a user defines explicit memory or cpu reservations within a custom KubeletConfig, Auto Sizing Reserved will automatically remain disabled to prevent conflicting configuration logic.

Related 4.20 Patch: For context on how older clusters are transitioned, please refer to the pre-requisite patch:

- How to verify it
The following scenarios were successfully validated:Upgrade Test (4.20 --> 4.21 + PR): A cluster created in 4.20 was upgraded to this 4.21 PR. Auto Sizing Reserved was confirmed to be disabled, preserving the pre-4.21 behavior.

New Cluster Test (4.21 + PR): A new cluster was provisioned in 4.21 with this PR. Auto Sizing Reserved was confirmed to be enabled by default.

Manual Test result

Here's the state of mc after upgrade from [4.20 + patch] to [4.21 + this pr]:

We can see "auto-sizing-disabled" mc

Here's the post upgrade NODE_SIZING_ENABLED:

oc debug node/ip-10-0-6-61.us-east-2.compute.internal                                                           ✔  admin 󱃾  23:24:58

Here are the nodes post upgrade, showing successful upgrade:

 oc get no                                                                                              ✔  1m 35s  admin 󱃾  23:26:53

Now I can apply kubeletconfig to enable auto sizing reserved:

oc apply -f 80-worker-auto.yaml                                                                                 ✔  admin 󱃾  23:26:57
kubeletconfig.machineconfiguration.openshift.io/80-worker-auto created

After applying the NODE_SIZING_ENABLED changes:

oc debug node/ip-10-0-6-61.us-east-2.compute.internal                                                           ✔  admin 󱃾  23:32:43

NODE_SIZING_ENABLED=true
SYSTEM_RESERVED_MEMORY=1Gi
SYSTEM_RESERVED_CPU=500m

Also we can see the KubeletConfig showing correct auto sizing reserved:

oc get kubeletconfig -o yaml                                                                            ✔  1m 6s  admin 󱃾  23:34:02

- What I did
This PR updates the default cluster configuration to enable Auto Sizing Reserved for all new OpenShift clusters created from version 4.21 onward.

New Cluster Default: New 4.21 clusters will now have Auto Sizing Reserved enabled by default

Upgrade Preservation:

We can see "auto-sizing-disabled" mc

Here's the post upgrade NODE_SIZING_ENABLED:

oc debug node/ip-10-0-6-61.us-east-2.compute.internal                                                           ✔  admin 󱃾  23:24:58

NODE_SIZING_ENABLED=false

Here are the nodes post upgrade, showing successful upgrade:

oc get no                                                                                              ✔  1m 35s  admin 󱃾  23:26:53

Now I can apply kubeletconfig to enable auto sizing reserved:

oc apply -f 80-worker-auto.yaml                                                                                 ✔  admin 󱃾  23:26:57
kubeletconfig.machineconfiguration.openshift.io/80-worker-auto created

After applying the NODE_SIZING_ENABLED changes:

oc debug node/ip-10-0-6-61.us-east-2.compute.internal                                                           ✔  admin 󱃾  23:32:43
Starting pod/ip-10-0-6-61us-east-2computeinternal-debug-f8jnj ...

If you don't see a command prompt, try pressing enter.

NODE_SIZING_ENABLED=true
SYSTEM_RESERVED_MEMORY=1Gi
SYSTEM_RESERVED_CPU=500m
SYSTEM_RESERVED_ES=1Gi
sh-5.1#

Also we can see the KubeletConfig showing correct auto sizing reserved:

oc get kubeletconfig -o yaml                                                                            ✔  1m 6s  admin 󱃾  23:34:02

@sairameshv I made the changes and retested setting system reserved manually. When system reserved is set via a kubelet config the auto-sizing-reserved is set to false as expected.

Test Result

Created the cluster with the PR using ClusterBot and check the NODE_SIZING_ENABLED flag:

oc debug node/ip-10-0-64-18.us-east-2.compute.internal 
Starting pod/ip-10-0-64-18us-east-2computeinternal-debug-4lthc ...

NODE_SIZING_ENABLED=true
SYSTEM_RESERVED_MEMORY=1Gi
SYSTEM_RESERVED_CPU=500m
SYSTEM_RESERVED_ES=1Gish-5.1# exit

Now applied a KubeletConfig with system reserved:

oc apply -f systemReserved.yaml                                                                                 ✔  admin 󱃾  08:23:14

Now checked if NODE_SIZING_ENABLED is set to false after the node restarts:

oc debug node/ip-10-0-64-18.us-east-2.compute.internal                                                          ✔  admin 󱃾  08:33:31
