Can I specify database in URI for elasticsearch?-CodePudding

Would this work?

.env:

ELASTIC_SEARCH_URI=http://localhost:9200/example-dev

The docs just say to use ELASTIC_SEARCH_URI=http://localhost:9200/ but I have two different apps on same dedicated server using elasticsearch. I want to specify a unique database for each app.

const es = new ElasticsearchClient({
  node: "http://localhost:9200",
  /*
    auth: {
        username: 'elastic',
        password: 'password'
    }
    */
});

CodePudding user response：

If you want multiple instances of Elasticsearch you can create 2 different containers, one will listen to :9200 and the other :9201 for example.

If what you mean by specifying database is different index. Then you can encapsulate the necessary function to your needs.

// search func in app 1
const esSearch = (body) => {
  const response = await es.search({
    target: "my-app1",
    body,
  });
}

// search func in app 2
const esSearch = (body) => {
  const response = await es.search({
    target: "my-app2",
    body,
  });
}

There is no specifying the database because Elasticsearch itself is a single database. You can create different indices for different data.

You can use below code for two different apps:

APP1

Lets consider datsource name for APP1 is example-dev

const es = new ElasticsearchClient({
  node: "http://localhost:9200",
  /*
    auth: {
        username: 'elastic',
        password: 'password'
    }
    */
});

const result = await es.search({
    index: 'example-dev',
    query: {
      match: {
        quote: 'winter'
      }
    }
  })

APP2

Lets consider datsource name for APP2 is example-dev-app2

const es = new ElasticsearchClient({
  node: "http://localhost:9200",
  /*
    auth: {
        username: 'elastic',
        password: 'password'
    }
    */
});

const result = await es.search({
    index: 'example-dev-app2',
    query: {
      match: {
        quote: 'winter'
      }
    }
  })
