Verified on OSP16+Octavia-OVN (RHOS_TRUNK-16.0-RHEL-8-20200513.n.1) with OCP4.5.0-0.nightly-2020-06-08-053957 NP and Conformance run without compromising kuryr-controller stability. No KeyError: 'status' observed. Manual reproduction also confirms the behaviour. Steps: #1. Create project with two pods and service. $ oc new-project test1 && oc run --image kuryr/demo demo && oc run --image kuryr/demo demo-caller && oc expose pod/demo --port 80 --target-port 8080 $ oc get all NAME READY STATUS RESTARTS AGE pod/demo 1/1 Running 0 2m27s pod/demo-caller 1/1 Running 0 2m27s NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE service/demo ClusterIP 172.30.92.184 <none> 80/TCP 2m26s $ oc rsh demo-caller curl 172.30.92.184 demo: HELLO! I AM ALIVE!!! $ oc get kuryrnetworks NAME SUBNET-CIDR AGE test1 10.128.114.0/23 2m23s #3. Edit kuryrnetwork CRD and remove the status section. Set the instruction to remove the project immediately before the status is fulfilled again by kuryr-controller: $ oc edit kuryrnetworks/test1 && oc delete project test1 && oc edit kuryrnetworks/test1 && oc delete project test1 && oc edit kuryrnetworks/test1 >> Remove below: status: netId: 0d3b19f5-e578-4f0b-9949-eaa3ca8afede nsLabels: {} populated: false routerId: 3a218a45-e158-4aad-90aa-ed67c97bc6c7 subnetCIDR: 10.128.114.0/23 subnetId: b9156704-b438-43cc-9baf-6d70ccf2ade0 #4. Confirm that KeyError exception does not take place and no restarts took place. $ oc logs -n openshift-kuryr $(oc get pods -n openshift-kuryr -o jsonpath='{.items[6].metadata.name}') | grep -i keyerror $ oc get pods -n openshift-kuryr NAME READY STATUS RESTARTS AGE kuryr-cni-6xthm 1/1 Running 0 49m kuryr-cni-c6n82 1/1 Running 0 49m kuryr-cni-cttpr 1/1 Running 0 49m kuryr-cni-kw8bm 1/1 Running 0 49m kuryr-cni-m45nr 1/1 Running 0 49m kuryr-cni-r2ct2 1/1 Running 0 49m kuryr-controller-696c89958-l5qrc 1/1 Running 0 23m [...]
