I am trying to use Kubernetes for a project I am working on, but I am having an issue with pod networking.
First, I followed along with the tutorials here https://kubernetes.io/docs/tutorials/kubernetes-basics/ Then I set this up with a local environment running minkube and repeated all of the exercises. Now, I have spun up a 4 node cluster (1 master, 3 workers) with vagrant. I have been able to successfully join the worker nodes into the cluster. Here is the output for "kubectl get nodes -o wide": NAME STATUS ROLES AGE VERSION EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME head Ready master 1h v1.9.1 <none> CentOS Linux 7 (Core) 3.10.0-693.11.6.el7.x86_64 docker://1.12.6 worker1 Ready <none> 1h v1.9.1 <none> CentOS Linux 7 (Core) 3.10.0-693.11.6.el7.x86_64 docker://1.12.6 worker2 Ready <none> 1h v1.9.1 <none> CentOS Linux 7 (Core) 3.10.0-693.11.6.el7.x86_64 docker://1.12.6 worker3 Ready <none> 1h v1.9.1 <none> CentOS Linux 7 (Core) 3.10.0-693.11.6.el7.x86_64 docker://1.12.6 I have deployed the image from the above tutorial. Here is the output for "kubectl get deployments -o wide": NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE CONTAINERS IMAGES SELECTOR kubernetes-bootcamp 1 1 1 1 44m kubernetes-bootcamp gcr.io/google-samples/kubernetes-bootcamp:v1 run=kubernetes-bootcamp I have also exposed the deployment. Here is the output of "kubectl get services -o wide": NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE SELECTOR kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 1h <none> kubernetes-bootcamp NodePort 10.110.105.36 <none> 8080:30037/TCP 38m run=kubernetes-bootcamp The pod is up and running (I currently only have one running, but I have scaled to 8 replicas and they all showed as running). Here is the output of "kubectl get pods -o wide": NAME READY STATUS RESTARTS AGE IP NODE kubernetes-bootcamp-5dbf48f7d4-qldkx 1/1 Running 0 46m 10.1.1.8 worker1 For an in depth look at the pod, here is the output of "kubectl describe pods": Name: kubernetes-bootcamp-5dbf48f7d4-qldkx Namespace: default Node: worker1/10.0.2.15 Start Time: Tue, 15 May 2018 15:36:40 +0000 Labels: pod-template-hash=1869049380 run=kubernetes-bootcamp Annotations: <none> Status: Running IP: 10.1.1.8 Controlled By: ReplicaSet/kubernetes-bootcamp-5dbf48f7d4 Containers: kubernetes-bootcamp: Container ID: docker://b17539ecb8dc641c2a82dbc1affbcc5b70cea0791318c6721b617032dc401541 Image: gcr.io/google-samples/kubernetes-bootcamp:v1 Image ID: docker-pullable://gcr.io/google-samples/kubernetes-bootcamp@sha256:0d6b8ee63bb57c5f5b6156f446b3bc3b3c143d233037f3a2f00e279c8fcc64af Port: 8080/TCP State: Running Started: Tue, 15 May 2018 15:37:00 +0000 Ready: True Restart Count: 0 Environment: <none> Mounts: /var/run/secrets/kubernetes.io/serviceaccount from default-token-gr5qg (ro) Conditions: Type Status Initialized True Ready True PodScheduled True Volumes: default-token-gr5qg: Type: Secret (a volume populated by a Secret) SecretName: default-token-gr5qg Optional: false QoS Class: BestEffort Node-Selectors: <none> Tolerations: node.kubernetes.io/not-ready:NoExecute for 300s node.kubernetes.io/unreachable:NoExecute for 300s Events: Type Reason Age From Message ---- ------ ---- ---- ------- Normal Scheduled 49m default-scheduler Successfully assigned kubernetes-bootcamp-5dbf48f7d4-qldkx to worker1 Normal SuccessfulMountVolume 49m kubelet, worker1 MountVolume.SetUp succeeded for volume "default-token-gr5qg" Normal Pulling 49m kubelet, worker1 pulling image "gcr.io/google-samples/kubernetes-bootcamp:v1" Normal Pulled 49m kubelet, worker1 Successfully pulled image "gcr.io/google-samples/kubernetes-bootcamp:v1" Normal Created 49m kubelet, worker1 Created container Normal Started 49m kubelet, worker1 Started container Now, even though everything looks fine, when I run "kubectl exec -ti kubernetes-bootcamp-5dbf48f7d4-qldkx bash", here is the message that I get: error: unable to upgrade connection: pod does not exist Does anyone have a solution to this?
