release notes 
# Significant changes

Deferred deletion / pruning phase


Some infrastructure changes are potentially disruptive to the continued

operation of the cluster.  For the most disruptive operations, particularly

those that break rolling-update of the cluster, we have started to use deferred

deletion to minimize the impact.  For example, on AWS we create a second NLB

during the kops update phase when we cannot change the NLB directly.

kops update will report that a --prune is needed.  To minimize disruption,

we recommend you perform this after a rolling-update, for example:


kops update $MYCLUSTER --yes --admin
kops rolling-update $MYCLUSTER --yes
kops update $MYCLUSTER --yes --admin --prune # NEW!



Deferred deletion is currently used to safely introduce security groups for NLBs on AWS,

and to move to an internal load balancer for kops-controller on GCP.


Initial OpenTelemetry Support


We are starting to add (experimental) support for OpenTelemetry,

in particular Tracing support.  Setting OTEL_EXPORTER_OTLP_TRACES_FILE

will write a trace file which can then be read by the traceserver program.

More information and options are described in docs/opentelemetry.md.

The tracing data is not expected to be particularly useful for end-users in

this release; the (non-standard) recording approach is instead intended to

work well with our Prow end-to-end testing system so that developers can

optimize kOps.


Please note: this is not telemetry in the "phone-home" sense.

The kOps project does not collect data from your machine.  As an

open-source project we do not even want to collect any of your data.

Currently the only OpenTelemetry backend supported is writing to a

filesystem (and it is opt-in).  In future you will be able to configure

other OpenTelemetry backends, but this data will only be sent if

you enable OpenTelemetry, and only sent to where you configure.


AWS


    

  • 

    Network Load Balancers in front of the Kubernetes API and bastion hosts now
    
have a security group attached. These security groups are used for security group rules
    
allowing incoming traffic to the NLBs as well as traffic between the NLBs and their target
    
instances.
    

    • 

  • 

    Posts event data to URL upon instance interruption action in aws-node-termination-handler with WEBHOOK_URL.
    

    • 



GCP


    

  • 

    As of Kubernetes version 1.29, credentials for private GCR/AR repositories will be handled by the out-of-tree credential provider. This is an additional binary that each instance downloads from the assets repository.
    

    • 

  • 

    Two additional StorageClasses are created on GCP clusters. These are called balanced-csi and ssd-csi and utilize the GCP Balanced and SSD Persistent Disk volume types respectively.
    

    • 

  • 

    Breaking Change - the default StorageClass has been changed from standard-csi to balanced-csi.
    

    • 

  • 

    We now use a private load-balancer for in-cluster traffic on GCP, which allows us
    
to use network tags to restrict access only to the cluster nodes.
    

    • 



Breaking changes


Other breaking changes


    

  • 

    kops toolbox dump limits the number of nodes dumped to 500 by default. Use --max-nodes to override.
    

    • 

  • 

    Support for Kubernetes version 1.23 has been removed.
    

    • 



Known Issues



Deprecations


    

  • 

    Support for Kubernetes version 1.24 is deprecated and will be removed in kOps 1.30.
    

    • 

  • 

    Support for Kubernetes version 1.25 is deprecated and will be removed in kOps 1.31.
    

    • 

  • 

    Support for AWS Classic Load Balancer for API is deprecated and should not be used for newly created clusters.
    

    • 

  • 

    All unmanaged addons (in addons/) are deprecated in favor of managed addons, including the metrics server addon and the autoscaler addon.
