elasticsearch - 删除所有具有相似名称的索引

Question

大家好，我的 elasticsearch 有 100 个索引，我想用一个查询删除它们。它们都以 myindex 开头:

myindex-1
myindex-2
myindex-3
myindex-4
  .
  .
  .
myindex-100

当我尝试此查询时，它不起作用:

curl -XDELETE http://localhost:9200/myindex*

我得到:

{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Wildcard expressions or all indices are not allowed"}],"type":"illegal_argument_exception","reason":"Wildcard expressions or all indices are not allowed"},"status":400}

你有什么主意吗？

Answer 1

Elasticsearch documentation说:

The delete index API can also be applied to more than one index, by either using a comma separated list, or on all indices (be careful!) by using _all or *as index.

In order to disable allowing to delete indices via wildcards or _all, set action.destructive_requires_namesetting in the config to true. This setting can also be changed via the cluster update settings api.

因此，如果您有预定义数量的索引要删除，这可能会起作用:

curl -XDELETE http://localhost:9200/myindex-1,myindex-2,myindex-3,myindex-4

如果您想使用通配符，则必须按照上述方式更新配置
