Voici mon problème : Je tente d’installer un cluster Kubernetes, un master déjà pour commencer. Je fais ça sur une VM Debian 10 (KVM, hôte en Debian 10 aussi). L’étape `kubeadm init` a bien abouti, je peux interroger le cluster : ``` $ kubectl cluster-info Kubernetes control plane is running at https://192.168.122.204:6443 KubeDNS is running at https://192.168.122.204:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'. ``` Ensuite j’ai installé un CNI : Flannel, puis j’ai voulu installer le dashboard. Et c’est là que ça chie. L’installation (ie: le kubectl apply -f ...) s’est bien déroulée, mais le pod ne démarre pas : ``` $ kubectl -n kubernetes-dashboard get pods NAME READY STATUS RESTARTS AGE dashboard-metrics-scraper-79c5968bdc-gxqct 0/1 CrashLoopBackOff 86 3d23h kubernetes-dashboard-9f9799597-cdcbc 0/1 ContainerCannotRun 53 3d23h ``` ``` $ kubectl -n kubernetes-dashboard describe pods kubernetes-dashboard-9f9799597-cdcbc |tail -n20 Warning FailedCreatePodSandBox 23h kubelet Failed to create pod sandbox: rpc error: code = Unknown desc = failed to start sandbox container for pod "kubernetes-dashboard-9f9799597-cdcbc": Error response from daemon: OCI runtime create failed: runc did not terminate sucessfully: unknown Warning FailedCreatePodSandBox 23h kubelet Failed to create pod sandbox: rpc error: code = Unknown desc = failed to start sandbox container for pod "kubernetes-dashboard-9f9799597-cdcbc": Error response from daemon: OCI runtime create failed: unable to retrieve OCI runtime error (open /run/docker/containerd/daemon/io.containerd.runtime.v1.linux/moby/00a5aab0c7edabe7c56fa373991492a3ebeffc64865b1b8b05b35a47bf5f7846/log.json: no such file or directory): runc did not terminate sucessfully: unknown Warning FailedCreatePodSandBox 23h kubelet Failed to create pod sandbox: rpc error: code = Unknown desc = failed to start sandbox container for pod "kubernetes-dashboard-9f9799597-cdcbc": Error response from daemon: OCI runtime create failed: unable to retrieve OCI runtime error (open /run/docker/containerd/daemon/io.containerd.runtime.v1.linux/moby/237fefb18f26557c180d856b0789c7edf4fab8134e07c15d7cbcc2aaeec51d64/log.json: no such file or directory): runc did not terminate sucessfully: unknown Warning FailedCreatePodSandBox 23h kubelet Failed to create pod sandbox: rpc error: code = Unknown desc = failed to start sandbox container for pod "kubernetes-dashboard-9f9799597-cdcbc": Error response from daemon: OCI runtime create failed: unable to retrieve OCI runtime error (open /run/docker/containerd/daemon/io.containerd.runtime.v1.linux/moby/e4a950a874522a6909b89217611da6aa10d49edf996f47635c54d3be2839e11d/log.json: no such file or directory): runc did not terminate sucessfully: unknown Warning FailedCreatePodSandBox 23h (x3 over 23h) kubelet Failed to create pod sandbox: rpc error: code = Unknown desc = failed to start sandbox container for pod "kubernetes-dashboard-9f9799597-cdcbc": Error response from daemon: failed to start shim: fork/exec /usr/bin/docker-containerd-shim: resource temporarily unavailable: unknown Warning FailedCreatePodSandBox 23h kubelet Failed to create pod sandbox: rpc error: code = Unknown desc = failed to start sandbox container for pod "kubernetes-dashboard-9f9799597-cdcbc": Error response from daemon: OCI runtime create failed: unable to retrieve OCI runtime error (open /run/docker/containerd/daemon/io.containerd.runtime.v1.linux/moby/fccfa3ebd614804419954d1d94d9c03e37885ddef0f4e2566114c9bb014092d6/log.json: no such file or directory): runc did not terminate sucessfully: unknown Warning FailedCreatePodSandBox 23h kubelet Failed to create pod sandbox: rpc error: code = Unknown desc = failed to start sandbox container for pod "kubernetes-dashboard-9f9799597-cdcbc": Error response from daemon: OCI runtime create failed: unable to retrieve OCI runtime error (open /run/docker/containerd/daemon/io.containerd.runtime.v1.linux/moby/ffea13900939584c5bd1d491f1dc695452849485c6718486975a77625bca1921/log.json: no such file or directory): runc did not terminate sucessfully: unknown Normal SandboxChanged 23h (x12 over 23h) kubelet Pod sandbox changed, it will be killed and re-created.
