以下示例展示 Docker 运行方式下各命令的完整用法。假设宿主机当前工作目录为升级项目目录。
|
||||
|
||||
```bash
|
||||
# -------------------------------------------------------
|
||||
# 定义镜像别名(可选,减少输入量)
|
||||
# -------------------------------------------------------
|
||||
alias db-operator='docker run --rm -it \
|
||||
--network host \
|
||||
--user $(id -u):$(id -g) \
|
||||
-v $(pwd):/data \
|
||||
-e DB_OPERATOR_PASSWORD \
|
||||
harbor.wdd.io:8033/rmdc/db-operator:v1.2.0'
|
||||
|
||||
# 执行数据库密码输入
|
||||
export DB_OPERATOR_PASSWORD=XXXXXX
|
||||
|
||||
# -------------------------------------------------------
|
||||
# ① 导出现场数据库结构基线(多个库按顺序分别导出)
|
||||
# -------------------------------------------------------
|
||||
db-operator export-structure \
|
||||
-H 192.168.1.100 -P 3306 -u root \
|
||||
--databases mydb_core,mydb_order \
|
||||
--output-dir ./export/
|
||||
|
||||
# 导出结果示例(文件名带 001/002 序号前缀,与 --databases 顺序一致):
|
||||
# ./export/001_mydb_core_structure_<timestamp>.sql
|
||||
# ./export/002_mydb_order_structure_<timestamp>.sql
|
||||
|
||||
# -------------------------------------------------------
|
||||
# ② 导入结构基线到临时 MySQL(目录模式)
|
||||
# -------------------------------------------------------
|
||||
db-operator import-structure \
|
||||
-H 127.0.0.1 -P 3306 -u root \
|
||||
--input ./export/
|
||||
|
||||
# 目录模式会按文件名自然序执行(001 -> 002 -> ...)
|
||||
|
||||
# -------------------------------------------------------
|
||||
# ②-补充:单文件导入(仍保留)
|
||||
# -------------------------------------------------------
|
||||
db-operator import-structure \
|
||||
-H 127.0.0.1 -P 3306 -u root \
|
||||
--input ./export/001_mydb_core_structure_<timestamp>.sql
|
||||
|
||||
# -------------------------------------------------------
|
||||
# ③-a 重置数据库(--database 必须与 baseline SQL 内数据库名一致)
|
||||
# -------------------------------------------------------
|
||||
db-operator reset-database \
|
||||
-H 127.0.0.1 -P 3306 -u root -d mydb_core \
|
||||
--baseline ./export/001_mydb_core_structure_<timestamp>.sql \
|
||||
--yes
|
||||
|
||||
# -------------------------------------------------------
|
||||
# ③-b 执行增量升级
|
||||
# -------------------------------------------------------
|
||||
db-operator run-upgrade \
|
||||
-H 127.0.0.1 -P 3306 -u root -d mydb_core \
|
||||
--migration-dir ./migrations/
|
||||
|
||||
# -------------------------------------------------------
|
||||
# ③-c 验证升级
|
||||
# -------------------------------------------------------
|
||||
db-operator verify-upgrade \
|
||||
-H 127.0.0.1 -P 3306 -u root -d mydb_core \
|
||||
--baseline ./export/001_mydb_core_structure_<timestamp>.sql
|
||||
|
||||
# -------------------------------------------------------
|
||||
# ④ 比对差异(纯文件操作,无需 --network host)
|
||||
# -------------------------------------------------------
|
||||
db-operator diff-schema \
|
||||
--source ./export/001_mydb_core_structure_before.sql \
|
||||
--target ./export/001_mydb_core_structure_after.sql
|
||||
|
||||
# -------------------------------------------------------
|
||||
# ⑤ 打包交付物
|
||||
# -------------------------------------------------------
|
||||
db-operator pack \
|
||||
--project myproject --version 2.3.1
|
||||
```
