crio's contract with networking is to have networking up when the container starts. Moving to the openshift-sdn team to help triage what is going on. this fixed PR is merged to build 4.12.0-0.nightly-2022-07-24-180529 So I update the target version to 4.12 version. still failed on build 4.12.0-0.nightly-2022-07-26-131732 Creating above statefulset and pod still cannot be worked with same error 27s Warning FailedPostStartHook pod/httpd-0 Exec lifecycle hook ([/bin/sh -c curl -k https://<IP:PORT> > /tmp/urltest.txt]) for Container "httpd" in Pod "httpd-0_default(7e519841-7092-4513-928b-03c7783ddc7d)" failed - error: command '/bin/sh -c curl -k https://<IP:PORT> > /tmp/urltest.txt' exited with 1: /bin/sh: -c: line 0: syntax error near unexpected token `>'... 85s Normal Killing pod/httpd-0 FailedPostStartHook Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: lifecycle.posStart does not have network connectivity on OpenShiftSDN CNI. (OVNKubernetes does not have the issue) Version-Release number of selected component (if applicable): 4.10 How reproducible: always Steps to Reproduce: 1. create statefulset ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ $ oc create -f statefulset.yaml $ cat statefulset.yaml apiVersion: apps/v1 kind: StatefulSet metadata: name: httpd spec: serviceName: "httpd" replicas: 1 selector: matchLabels: app: httpd template: metadata: labels: app: httpd spec: containers: - name: httpd image: registry.redhat.io/rhel8/httpd-24:1-191 ports: - containerPort: 80 name: web lifecycle: postStart: exec: command: - /bin/sh - -c - curl -k https://<IP:PORT> > /tmp/urltest.txt ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Actual results: PostStartHook fails ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 36s Normal Killing pod/httpd-0 FailedPostStartHook ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Expected results: PostStartHook should not fail. Additional info: by adding a dummy initContainers, you can workaround the issue. something like this: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ spec: initContainers: - name: init-myservice image: busybox:1.28 command: ['sh', '-c', 'sleep 2'] containers: - name: httpd image: registry.redhat.io/rhel8/httpd-24:1-191 ports: - containerPort: 80 name: web lifecycle: postStart: exec: command: - /bin/sh - -c - curl -k <IP:PORT> > /tmp/urltest.txt .... ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
