Calico Readiness probe failed: calico/node is not ready故障处理

calico 报如下错误

Readiness probe failed: calico/node is not ready: BIRD is not ready: Error querying BIRD: unable to connect to BIRDv4 socket: dial unix /var/run/calico/bird.ctl: connect: connection refused

解决方案：

修改 ds calico-node配置文件加入如下两行

- name: IP_AUTODETECTION_METHOD
  value: "interface=eth0"

value指向从ip a看到的实际网卡名。

具体操作步骤

1. 编辑ds calico-node加入配置

kubectl edit ds calico-node -n kube-system

# Cluster type to identify the deployment type
- name: CLUSTER_TYPE
  value: "k8s,bgp"
- name: IP_AUTODETECTION_METHOD  # 新增
  value: "interface=eth0"        # 新增
# Auto-detect the BGP IP address.
- name: IP
  value: "autodetect"
# Enable IPIP
- name: CALICO_IPV4POOL_IPIP
  value: "Always"

2. 重启calico

kubectl rollout restart daemonset calico-node  -n kube-system 
daemonset.apps/calico-node restarted
