Introduction

TiDB Data Migration（DM）官方镜像，将 MySQL/MariaDB 增量同步到 TiDB，支持分库分表合并与在线迁移，用于数据库上云与异构同步。

Details

DM 由 PingCAP 维护，包含 dm-master、dm-worker 与同步逻辑，需配合 TiDB 集群与上游 MySQL binlog。Docker 常用于组件测试；生产推荐 TiUP/K8s Operator 部署 HA master-worker。配置 task YAML 时需指定 source-id、路由规则与 binlog GTID；迁移前务必全量备份并验证校验任务。

快速启动

docker run --rm docker.io/pingcap/dm:latest \
  dm-master --help

推荐实践

# 生产请用 TiUP: tiup cluster deploy dm-test dm v8.1.0 ...
# 镜像用于本地验证:
docker run -d --name dm-master \
  --restart unless-stopped \
  -p 8261:8261 \
  -v /etc/dm:/etc/dm \
  docker.io/pingcap/dm:v8.1.0 \
  dm-master --config=/etc/dm/master.toml

核心参数说明

  • dm-master — 调度与元数据管理，8261 为 API/监控端口
  • -v /etc/dm — master/worker 配置与 task YAML
  • dm:v8.1.0 — 与 TiDB 集群版本配套
  • TiUP 优先 — 多 worker HA 不建议单机 docker run
  • 上游 binlog — MySQL 需 ROW 格式与 GTID 开启
