From 5afb24809d15ce9a9c549b063700b6338a7f1d06 Mon Sep 17 00:00:00 2001 From: Kevin Zhao Date: Fri, 29 Mar 2019 09:27:57 +0800 Subject: [PATCH] Add OpenStack Zun provider(#22) (#239) * Add Virtual Kubelet provider for OpenStack Zun Initial virtual kubelet provider for OpenStack Zun. This provider currently handles creating, starting and deleting a pod via OpenStack Zun. Currently the configmap and secret is not support in Zun. Currently the Volume is supported in Zun and will implementation the support in virtual kubelet in next several patches. Will add document to elaborate this development status. Change-Id: Id80f18d89b22c535214aef95254f5c3c7ae23139 Signed-off-by: Kevin Zhao * trying to fix dependencies Change-Id: I8e6f2e0234a11591ff2be74e22dca1fb91bf8f47 Signed-off-by: Davanum Srinivas * Add dummy ExecInContainer method Change-Id: Idece5695bd81b0911538660526484895cdd8832c Signed-off-by: Davanum Srinivas * better use of fmt.Errorf Change-Id: Ic402c80bd2302ac4f26b0025f110cbf9977ca862 Signed-off-by: Davanum Srinivas * fix gofmt error Signed-off-by: Kevin Zhao * add gophercloud vendor Signed-off-by: Kevin Zhao * add provider register for openstack Signed-off-by: Kevin Zhao * fix build error Signed-off-by: Kevin Zhao * excluded aci test case Signed-off-by: Kevin Zhao * Zun: several fixes on openstack provider * Remove 'zunCapStatusToPodPhase' since it is not used anymore. * Remove the handling of first container in capsule. * Remove 'ApiVersion' from CapsuleTemplate Signed-off-by: Hongbin Lu * Update gophercloud to latest * Zun: use Zun API micro version 1.32 Signed-off-by: Hongbin Lu * Zun: wait for capsule to be deleted Resource deletion in OpenStack Zun is asynchronous which means the resource is not deleted immediately right after the delete request. This commit make the provider wait for resource deletion to complete on DeletePod.
