etcd常用操作

1. 设置环境变量，设置证书

rke部署的k8s,etcd集群

export ETCD_ENDPOINTS="https://127.0.0.1:2379"  # 设置连接点
export ETCD_CERT_FILE="/etc/kubernetes/ssl/kube-etcd-192-168-10-211.pem"
export ETCD_KEY_FILE="/etc/kubernetes/ssl/kube-etcd-192-168-10-211-key.pem"
export ETCD_CACERT_FILE="/etc/kubernetes/ssl/kube-ca.pem"

2. 执行etcdctl命令

# 查看监控状态

etcdctl endpoint status --write-out=table

etcdctl member list --write-out=table

# 删除成员节点
etcdctl member remove <member-id>
