使用官方示例
- etcd:
- image: bitnami/etcd:3.4.15
- restart: always
- volumes:
- - ./etcd_data:/bitnami/etcd
- environment:
- ALLOW_NONE_AUTHENTICATION: "yes"
- ETCD_ADVERTISE_CLIENT_URLS: "http://etcd:2379"
- ETCD_LISTEN_CLIENT_URLS: "http://0.0.0.0:2379"
-
- ports:
- - "2379:2379/tcp"
- networks:
- docker:
备份
ETCDCTL_API=3 docker exec -it etcd etcdctl --endpoints=":2379" snapshot save "/bitnami/etcd/snapshot.db"
这时snapshot.db文件在./etcd_data下面,可以复制到对应宿主机上的etcd映射目录下
恢复
-
- 1
- docker docker exec -it api-etcd-1 bash
- 2
- etcdctl snapshot restore /bitnami/etcd/snapshot.db --data-dir /bitnami/etcd/new_data
- 3
- 退出变更配置,指定新的数据目录 - ./etcd_data/new_data:/bitnami/etcd/data
- 4
- 重新启动服务
