Hi

I am trying to run Chapter 7 to learn about Haystack for QA:

I am using Jupyter Notebook which is connected to my GCP VM : Debian GNU/Linux 9, Tesla V100  
I did install debian version  
but facing the following error : ConnectionError: Initial connection to Elasticsearch failed. Make sure you run an Elasticsearch instance at `[{'host': 'localhost', 'port': 9200}]` and that it has finished the initial ramp up (can take \> 30s).

!wget [https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.1.2-linux-x86\_64.tar.gz](https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.1.2-linux-x86_64.tar.gz)  
!wget [https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.1.2-linux-x86\_64.tar.gz.sha512](https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.1.2-linux-x86_64.tar.gz.sha512)  
!shasum -a 512 -c elasticsearch-8.1.2-linux-x86\_64.tar.gz.sha512  
!tar -xzf elasticsearch-8.1.2-linux-x86\_64.tar.gz  
!cd elasticsearch-8.1.2/  
!pip install pymilvus  
import pymilvus  
import os  
from subprocess import Popen, PIPE, STDOUT

!chown -R daemon:daemon elasticsearch-8.1.2  
es\_server = Popen(args=[‘elasticsearch-8.1.2/bin/elasticsearch’])  
!sleep 30

from haystack.document\_store.elasticsearch import ElasticsearchDocumentStore

#document\_store = ElasticsearchDocumentStore(host=‘localhost’, port= 9201, username=’’, password=’’)  
document\_store = ElasticsearchDocumentStore(return\_embedding=True)

I would appreciate your support on this.

Hi! the solution is launch ES:

```auto
from haystack.utils import launch_es
launch_es()

```

Before launching ES, we need to install docker to run ES locally, [here](https://docs.docker.com/engine/install/ubuntu/) the link to install [docker](https://docs.docker.com/engine/install/ubuntu/)  
After Docker installed, we need to change permission to use it as $USER:

```auto
sudo usermod -aG docker $USER
sudo reboot

```

Thats all:)
