[Test Fix] Mock docker network dependencies and fix filtering bug This PR only affects the mocked docker runtime, and has no impact on the kubelet. Issue #53327 When kubernetes creates a pod using the docker shim, it creates a container which contains the pod's network namespace, and then creates containers which specify that namespace. The current mocked docker does not mock this interaction, and thus allows a container to be created even when the container whose network it is joining does not exist. This allows the mocked kubelet to end up in a state where the pod does not exist, but a container in the pod does, and this breaks pod deletion. This fixes the above by only allowing containers to be started if the container whose network it is trying to join is running. Additionally, this PR fixes a filtering bug where we were incorrectly comparing docker container statuses. /assign @shyamjvs can you test this to see if it fixes the issue? /assign @Random-Liu for approval after @shyamjvs confirms this works. |

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.
