编辑在以下示例中，将创建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 组件模板存在。
创建组件模板 logs-foo_component1。必须在索引模板之前创建它，因为它不是可选的。
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，将以下条目添加到配置中：
"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"
}
}
}
}
}
这不会立即对数据流产生影响。只有在下次数据流自动滚动更新或触发手动滚动更新时，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
