Elasticsearch Create Index Template

Create an Elasticsearch Template with following command:

curl -XPUT -u elastic:changeme ‘localhost:9200/template/people_1?pretty’ -H ‘Content-Type: application/json’ -d’
{
“template”: “people_1*”,
“settings”: {
“number_of_shards”: 1,
“refresh_interval”: “3s”
},
“mappings”: {
“people_type”: {
“_source”: {
“enabled”: true
},
“properties”: {
“id”: {
“type”: “text”,
“fields”: {
“keyword”: {
“type”: “keyword”,
“ignore_above”:256
}
}
},
“name”: {
“type”: “text”,
“fields”: {
“keyword”: {
“type”: “keyword”,
“ignore_above”:256
}
}
},
“surname”: {
“type”: “text”,
“fields”: {
“keyword”: {
“type”: “keyword”,
“ignore_above”:256
}
}
},
“username”: {
“type”: “text”,
“fields”: {
“keyword”: {
“type”: “keyword”,
“ignore_above”:256
}
}
},
“age”: {
“type”: “integer”
},
“created_at”: {
“type”: “date”
}
}
}
},
“aliases”: {}
}

Elasticsearch post new document to people_1_june index

curl -XPUT -u elastic:changeme ‘localhost:9200/people_1_june/people_type’ -H ‘Content-Type: application/json’ -d’
{
“id”: “3d7797e5-736f-441a-8a13-9a997ee71e17”,
“age”: 27,
“name”: “oguzhan”,
“surname”:”karacullu”,
“username”:”mete00”,
“created_at”: “2017-06-17”
}
‘

• After creating the ES indexes and documents,

• first change “application.yml” then,

• gradle clean

• gradle build

• gradle bootRun

Create Person with RestApi:

curl -H “Content-Type: application/json” -X POST -d
‘{“name”: “Oguzhan”,”surname”: “Karacullu”,”username”: “oguz00”,”age”: 27}’ http://localhost:8080/person

Get All Person from ES index with Java Api if exist, else getter from local PostgreSql DB

curl -i -H “Accept: application/json” -H “Content-Type: application/json” -X GET ‘http://localhost:8080/person/all‘

spring-boot-kotlin-actuator

curl -i -H “Accept: application/json” -H “Content-Type: application/json” -X GET ‘http://localhost:8080/details‘

For Example Monitoring Endpoints:
-X GET ‘http://localhost:8080/details/mappings‘
