私は Kubernetes 1.13.2 を実行しており、kubeadm を使用してセットアップし、calico 3.5 の起動と実行に苦労しています。クラスターは KVM 上で実行されます。

設定:

  1. kubeadm init --apiserver-advertise-address=10.255.253.20 --pod-network-cidr=192.168.0.0/16
  2. 以下を含むように変更されたcalico.yamlファイル:

        - name: IP_AUTODETECTION_METHOD
          value: "interface=ens.*"
    
  3. 適用済みrbac.yaml, etcd.yaml,calico.yaml

からの出力kubectl describe pods:
