Elasticserach Dummy Responder (Success)

Dummy server to mimic elasticsearch success response upon receiving bulk post requests. I personally use this simple app for testing codes I developed, especially the one that require interaction with elasticsearch server for sending bulk post request.

Limitation

• Currently doesn't support HTTPS
• Only accept _bulk operation

Installation

To install this application, the following requirements needs to be met

• nodejs ^6.0.0
• npm ^5.0.0

then clone this repository using the following command

git clone https://github.com/rimaulana/elasticsearch-dummy-success-responder.git

once the codes were downloaded, cd into the directory and then run

npm install

Running the service

To run the service simply run

npm run server

by default this application will listen to port 3000. However, it can simply be configure by changing it in config.json file.

{
    "port": 3000
}

Running on Docker

You can build this application into docker by running the following command

docker build -t rimaulana/fake-es .

and you can simply run the container by executing

docker run -d -p 3000:3000 rimaulana/fake-es

Testing with postman

In order to check whether this app is running, it can simply be tested by sending request to this app using postman.

Setting URL and METHOD

Method should be POST and url will depend on the config. However, the default would be http://localhost:3000/_bulk

Defining Content-Type header

The acceptable Content-Types header are

• application/x-ndjson
• text/plain

Defining body

body needs to be set to raw, for testing purpose, use the following body

{ "index" : { "_index" : "test", "_type" : "type1", "_id" : "1" } }
{ "field1" : "value1" }
{ "delete" : { "_index" : "test", "_type" : "type1", "_id" : "2" } }
{ "create" : { "_index" : "test", "_type" : "type1", "_id" : "3" } }
{ "field1" : "value3" }
{ "update" : {"_id" : "1", "_type" : "type1", "_index" : "test"} }
{ "doc" : {"field2" : "value2"} }

Getting response

response should look like following

{
    "took": 30,
    "errors": false,
    "items": [
        {
            "index": {
                "_index": "test",
                "_type": "type1",
                "_id": "1",
                "_version": 1,
                "result": "created",
                "_shards": {
                    "total": 2,
                    "successful": 1,
                    "failed": 0
                },
                "status": 201,
                "_seq_no": 0,
                "_primary_term": 1
            }
        },
        {
            "delete": {
                "_index": "test",
                "_type": "type1",

                "_version": 1,
                "result": "deleted",
                "_shards": {
                    "total": 2,

                    "failed": 0
                },
                "status": 200,
                "_seq_no": 1,
                "_primary_term": 2
            }
        },
        {
            "create": {
                "_index": "test",
                "_type": "type1",
                "_id": "3",
                "_version": 1,
                "result": "created",
                "_shards": {
                    "total": 2,
                    "successful": 1,
                    "failed": 0
                },
                "status": 201,
                "_seq_no": 2,
                "_primary_term": 3
            }
        },
        {
            "update": {
                "_index": "test",
                "_type": "type1",
                "_id": "1",
                "_version": 2,
                "result": "updated",
                "_shards": {
                    "total": 2,
                    "successful": 1,
                    "failed": 0
                },
                "status": 200,
                "_seq_no": 3,
                "_primary_term": 4
            }
        }
    ]
}

Health check

This app has health check utility for making sure that the service is running via GET method on / path. the request send should return

{
    "name": "Dummy ES",
    "version": {
        "number": "0.1.0",
        "build_hash": "m93b675",
        "build_date": "2017-11-29T06:51:46.989Z",
        "build_snapshot": true,
        "lucene_version": "doesn't use lucene"
    },
    "tagline": "You Know, only for _bulk"
