Problems after the installation of IBM Cloud Private Configuring calicoctl After the cluster is installed, it could present IP connectivity issues across the pods. Service  name resolution issues are a symptom of pods not being able to reach the DNS service.  These problems are not always related to Calico networks. In these situations, gather the following information from the cluster for support: Collect logs from the  calico-node-* pod running on the node which is experiencing the  mesh problem. Example 8-6 shows how to get the logs from  calico-node-*  running on  node  10.10.25.71 . kubectl get nodes -o wide 1. Get the node list: 2. Get the logs: 3. Retrieve the logs from the  calico-node  container in the pod: 4. Get the routing table and interface details to complete this. Run the commands on master  node(s) + nodes on which pods are experiencing the connectivity issues. 5. Get Calico node list running the command on the master node: 6. Get all the pods and endpoints on Calico mesh by running the command on the IBM Cloud  Private master node: 7. Get calico node status and diagnostics. Run the commands on the IBM Cloud Private  master node and the nodes on which pods are experiencing connectivity problem: 8. Provide  config.yaml  and host files from boot node. 1. Log in to the node. Find the  calico-ctl  docker image and copy the  calicoctl  to node as  shown in Example 8-7. Example 8-6 Getting the logs Example 8-7 Copy the calicoctl to node Perform the following steps: # kubectl get pods -o wide | grep calico-node calico-node-amd64-2cbjh 2/2 Running 0 7h 10.10.25.70 10.10.25.70 calico-node-amd64-48lf9 2/2 Running 0 7h 10.10.25.71 10.10.25.71 calico-node-amd64-75667 2/2 Running 0 7h 10.10.25.7 10.10.25.7 # kubectl logs calico-node-amd64-48lf9 -c calico-node-amd64 route -n ifconfig -a calicoctl get nodes calicoctl get workload endpoints calicoctl node status calicoctl node diags # docker images | grep "icp-inception" ibmcom-amd64/icp-inception 3.1.0-ee c816bd4546f9 2 days ago 746MB 278  IBM Cloud Private System Administrator’s Guide
