使用示例
编辑使用示例
编辑在以下示例中,创建了一个组件模板和一个索引模板。索引模板引用了两个组件模板,但只有 @package
模板存在。
创建组件模板 logs-foo_component1
。由于此模板不是可选的,因此必须在索引模板之前创建。
resp = client.cluster.put_component_template( name="logs-foo_component1", template={ "mappings": { "properties": { "host.name": { "type": "keyword" } } } }, ) print(resp)
response = client.cluster.put_component_template( name: 'logs-foo_component1', body: { template: { mappings: { properties: { 'host.name' => { type: 'keyword' } } } } } ) puts response
const response = await client.cluster.putComponentTemplate({ name: "logs-foo_component1", template: { mappings: { properties: { "host.name": { type: "keyword", }, }, }, }, }); console.log(response);
PUT _component_template/logs-foo_component1 { "template": { "mappings": { "properties": { "host.name": { "type": "keyword" } } } } }
接下来,将创建索引模板,它引用了两个组件模板。
"composed_of": ["logs-foo_component1", "logs-foo_component2"]
之前,只创建了 logs-foo_component1
组件模板,这意味着 logs-foo_component2
缺失。因此,以下条目已添加到配置中。
"ignore_missing_component_templates": ["logs-foo_component2"],
在创建模板期间,它不会验证 logs-foo_component2
是否存在。
resp = client.indices.put_index_template( name="logs-foo", index_patterns=[ "logs-foo-*" ], data_stream={}, composed_of=[ "logs-foo_component1", "logs-foo_component2" ], ignore_missing_component_templates=[ "logs-foo_component2" ], priority=500, ) print(resp)
response = client.indices.put_index_template( name: 'logs-foo', body: { index_patterns: [ 'logs-foo-*' ], data_stream: {}, composed_of: [ 'logs-foo_component1', 'logs-foo_component2' ], ignore_missing_component_templates: [ 'logs-foo_component2' ], priority: 500 } ) puts response
const response = await client.indices.putIndexTemplate({ name: "logs-foo", index_patterns: ["logs-foo-*"], data_stream: {}, composed_of: ["logs-foo_component1", "logs-foo_component2"], ignore_missing_component_templates: ["logs-foo_component2"], priority: 500, }); console.log(response);
PUT _index_template/logs-foo { "index_patterns": ["logs-foo-*"], "data_stream": { }, "composed_of": ["logs-foo_component1", "logs-foo_component2"], "ignore_missing_component_templates": ["logs-foo_component2"], "priority": 500 }
索引模板 logs-foo
已成功创建。可以基于此模板创建数据流。
resp = client.indices.create_data_stream( name="logs-foo-bar", ) print(resp)
response = client.indices.create_data_stream( name: 'logs-foo-bar' ) puts response
const response = await client.indices.createDataStream({ name: "logs-foo-bar", }); console.log(response);
PUT _data_stream/logs-foo-bar
查看数据流的映射,它将包含 host.name
字段。
在稍后的阶段,可能会添加缺失的组件模板。
resp = client.cluster.put_component_template( name="logs-foo_component2", template={ "mappings": { "properties": { "host.ip": { "type": "ip" } } } }, ) print(resp)
response = client.cluster.put_component_template( name: 'logs-foo_component2', body: { template: { mappings: { properties: { 'host.ip' => { type: 'ip' } } } } } ) puts response
const response = await client.cluster.putComponentTemplate({ name: "logs-foo_component2", template: { mappings: { properties: { "host.ip": { type: "ip", }, }, }, }, }); console.log(response);
PUT _component_template/logs-foo_component2 { "template": { "mappings": { "properties": { "host.ip": { "type": "ip" } } } } }
这不会对数据流产生即时影响。只有在下一次数据流自动滚动或手动触发滚动时,映射 host.ip
才会显示在数据流映射中。
resp = client.indices.rollover( alias="logs-foo-bar", ) print(resp)
response = client.indices.rollover( alias: 'logs-foo-bar' ) puts response
const response = await client.indices.rollover({ alias: "logs-foo-bar", }); console.log(response);
POST logs-foo-bar/_rollover
