Add support for hostPath #15648

amarflybot · 2024-12-09T13:53:18Z

Description

This feature introduces support for the hostPath volume type in Knative Serving, enabling users to mount directories from the host node’s filesystem into their service containers. This allows direct access to node-specific data or preloaded resources like certificates, enhancing flexibility while retaining Knative’s serverless capabilities.

Proposed Changes

Add support for the hostPath volume type in Knative Serving.
Enable users to mount directories from the host node's filesystem into their Knative service containers.
Update relevant documentation and examples to include usage of hostPath volumes.

Release Note


Adding support for the "hostPath" volume type. The feature allows users to mount directories from the host node's filesystem into their Knative service containers. It enables access to local storage on the node, facilitating use cases such as accessing node-specific data or utilizing local caches. The feature is behind the flag `kubernetes.podspec-volumes-hostpath`.

Hi @amarflybot. Thanks for your PR.

I'm waiting for a knative member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
