Docker with ElasticSearch

[sankalp-acl]

I'm trying to set up the ElasticsearchDocumentStore in memory within an AWS EC2 instance. As a prerequisite, I'm running the below command (from a python script) but running into issues related to docker (error messages also mentioned below)

from haystack.utils import launch_es
launch_es()

Error messages from the log

/bin/sh: 1: docker: not found
WARNING: haystack.utils.doc_store: Tried to start Elasticsearch through Docker but this failed. It is likely that there is already an existing Elasticsearch instance running. 

Any help to resolve this error is appreciated!

From /bin/sh: 1: docker: not found, it seems that Docker is not installed.

Depending on your system/preferences you have two possible solutions:

• Install Docker in your system and retry with the current approach
• Manually download Elasticsearch and run it from source, as you see in this Haystack tutorial
