Silk Release for CFCR

Konstantin Kiess

Kubernetes networking operates sufficiently when requests are generated from within a cluster. If you need to access your pods from outside the cluster, it can be a problem.

Silk Release for CFCR is a Cloud Foundry pluggable container networking solution used alongside CF Networking. It provides networking via the Silk CNI plugin and enforces a policy that is stored in the Policy Server. During the meeting, Konstantin Kiess of Stark & Wayne demonstrated how to use the plugin.

Silk Release for CFCR enables container-to-container networking from Cloud Foundry to Kubernetes by employing silk-cni.
