Miheer, can you look into the failure to resolve github.com? Sure Miciah. Just working on to reproduce this issue. *** This bug has been marked as a duplicate of bug 1991067 *** |
Description of problem: Builder/deployment pods are unable to resolve domains, e.g. source S2I builds fail with the following message: Could not resolve host: github.com The issue does not seem to be occuring elsewhere than pods, for example, importing images from remote registries functions. The OCP4.6/4.7 clusters installed with same configuration do not have any issues with resolving domain names. OpenShift release version: 4.8.2, 4.8.3, 4.8.4 Cluster Platform: IPI OpenStack, x86_64 VMs How reproducible: Always Steps to Reproduce (in detail): 1. Install OCP 4.8 cluster on OpenStack with IPI 2. Once cluster is ready, import registry.access.redhat.com/ubi8/openjdk-11:latest cat <<-EOF | ./oc apply -f - apiVersion: image.openshift.io/v1 kind: ImageStream metadata: name: openjdk-11 spec: lookupPolicy: local: false tags: - name: latest from: kind: DockerImage name: registry.access.redhat.com/ubi8/openjdk-11:latest 3. Create source S2I build with the created imagestream: oc new-app openjdk-11 https://github.com/quarkusio/quarkus-quickstarts.git\#1.11 --context-dir=getting-started --name=getting-started Actual results: Build fails as git in build pod is unable to resolve github.com Expected results: Build succeeds Additional info: install-config.yaml apiVersion: v1 baseDomain: ${QUARKUS_QE_DOMAIN} metadata: name: ${OPENSHIFT_CLUSTER_NAME} controlPlane: name: master platform: {} replicas: 3 compute: - name: worker platform: openstack: type: ${OPENSTACK_FLAVOR_COMPUTE} replicas: 3 networking: clusterNetwork: - cidr: 10.128.0.0/14 hostPrefix: 23 machineCIDR: 172.208.0.0/16 networkType: OpenShiftSDN serviceNetwork: - 172.30.0.0/16 platform: openstack: cloud: openstack computeFlavor: ${OPENSTACK_FLAVOR_CONTROL_PLANE} externalDNS: null externalNetwork: ${OPENSTACK_NETWORK} lbFloatingIP: ${OPENSTACK_FLOATING_IP_API} octaviaSupport: "0" region: "regionOne" trunkSupport: "1" publish: External pullSecret: '$(cat ${OPENSHIFT_PULL_SECRET})' sshKey: '$(cat ${OPENSHIFT_SSH_KEY})' ========================= ** Please do not disregard the report template; filling the template out as much as possible will allow us to help you.
