Automatic merge from submit-queue Allow Partial Success for ImageGC Fixes #44951. When the eviction manager is under disk pressure, it first attempts to reclaim disk space by deleting images. However, if there are any errors during the image deletion process, the eviction manager treats that as a failed attempt delete images--even if some were successfully deleted. This change essentially makes the eviction manager ignore errors during image garbage collection, and instead rely solely on the quantity of resources reclaimed. If image deletion completely fails, for example, then this should still work as it would return 0 bytes freed. This allows for partial success, because any resources freed are counted, regardless of if some images fail to be deleted, for example. This does not require any changes to the image manager, as the current behavior is already to return the disk space freed along with any errors. ```release-note Fixes a bug where pods were evicted even after images are successfully deleted. ``` cc @dchen1107 @vishh @kubernetes/kubernetes-release-managers note to reviewers: this is mostly whitespace changes, so it will make more sense in reviewable |

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts, providing basic mechanisms for deployment, maintenance, and scaling of applications.
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.
To start using Kubernetes
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To start developing Kubernetes
The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.
If you want to build Kubernetes right away there are two options:
You have a working Go environment.
$ go get -d k8s.io/kubernetes
$ cd $GOPATH/src/k8s.io/kubernetes
$ make
You have a working Docker environment.
$ git clone https://github.com/kubernetes/kubernetes
$ cd kubernetes
$ make quick-release
If you are less impatient, head over to the developer's documentation.
Support
If you need support, start with the troubleshooting guide and work your way through the process that we've outlined.
That said, if you have questions, reach out to us one way or another.
