rules 命令

rules create

创建一个新的规则:

## 创建一个测试规则，简单打印所有发送到 't/a' 主题的消息内容
$ ./bin/emqx_ctl rules create \
  'test1' \
  'message.publish' \
  'select * from "t/a"' \
  '[{"name":"built_in:inspect_action", "params": {"a": 1}}]' \
  -d 'Rule for debug'
Rule test1:1556242324634254201 created

Tip

一个规则由系统生成的规则 ID 标识，所以如果用相同的名字重复添加规则，会生成多个 ID 不同的规则。

rules list

列出当前所有的规则:

$ ./bin/emqx_ctl rules list
rule(id='test1:1556242324634254201', name='test1', for='message.publish', rawsql='select * from "t/a"', actions=[{"name":"built_in:inspect_action","params":{"a":1}}], enabled='true', description='Rule for debug')

rules show

查询规则:

## 查询 RuleID 为 'test1:1556242324634254201' 的规则
$ ./bin/emqx_ctl rules show 'test1:1556242324634254201'

rules delete

## 删除 RuleID 为 'test1:1556242324634254201' 的规则
