备份

ETCDCTL_API=3 etcdctl snapshot save snapshot.db
ETCDCTL_API=3 etcdctl  snapshot status snapshot.db -w=table

还原

在 containers 同级增加以下yaml 同时挂载pvc进去

initContainers:
  - name: data-restore
    image: 'harbor.axzo.cn/ops/etcd:3.5.4-debian-11-r14'
    command:
      - /bin/bash
    args:
      - '-c'
      - 'rm -rf /bitnami/etcd/data/* && etcdctl snapshot restore /restore-volume/20240617_030015_apisix_snapshot.db --name $(MY_POD_NAME) --data-dir=/bitnami/etcd/data --initial-cluster pro-apisix-etcd-0=http://pro-apisix-etcd-0.pro-apisix-etcd-headless.pro-apisix.svc.cluster.local:2380,pro-apisix-etcd-1=http://pro-apisix-etcd-1.pro-apisix-etcd-headless.pro-apisix.svc.cluster.local:2380,pro-apisix-etcd-2=http://pro-apisix-etcd-2.pro-apisix-etcd-headless.pro-apisix.svc.cluster.local:2380 --initial-cluster-token etcd-cluster-k8s --initial-advertise-peer-urls http://$(MY_POD_NAME).pro-apisix-etcd-headless.pro-apisix.svc.cluster.local:2380'
