I have modified kubectl's edit command (/pkg/kubectl/cmd/edit.go) to restart all active pods to reflect the new changes immediately after the edit is done. (A down time is acceptable in my use case). Now I want to include this feature to the REST api, where when I call
PATCH /api/v1/namespaces/{namespace}/replicationcontrollers/{name}the patch should be applied to the replicationController and restart all the pods that are maintained by the corresponding replication controller. How ever I can't find the file that I should edit in order to alter the REST API. Where can I find these files and is there a better way to achieve what I am currently doing. (Edits to the RC should be reflect immediately in the pods)
We're actually implementing this feature in the Deployment API. You want the Recreate update strategy. It will be in Kubernetes 1.2, but you can try it now, in v1.2.0-alpha.6 or by building from HEAD.
https://github.com/kubernetes/kubernetes/blob/master/docs/user-guide/deployments.md
That documentation is a little out of date, since Deployment is under active development. For the current API, please see https://github.com/kubernetes/kubernetes/blob/master/pkg/apis/extensions/v1beta1/types.go
