Failed to establish a new connection, Docker-Compose Django + Haystack + Mysql + ElasticSearch - elasticsearch

Question

When I enter on the url http://0.0.0.0:9200/ is working.
I am getting the following error when I want to save or retrieve data:
ConnectionError(<urllib3.connection.HTTPConnection object at
0x7f234afdacc0>: Failed to establish a new connection: [Errno 111]
Connection refused) caused by:

I tried to create e network between web and elastic search, same result.
When I call http://0.0.0.0:9200/ I get a response from server with a JSON.
My Haystack config in settings.py
HAYSTACK_CONNECTIONS = {
'default': {
'ENGINE':'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
'URL': '0.0.0.0:9200/',
'INDEX_NAME': 'haystack'
}
}
HAYSTACK_SIGNAL_PROCESSOR = 'haystack.signals.RealtimeSignalProcessor'
Some content so I can post this question, Is not only code.

Answer 1

You should use elasticsearch instead of 0.0.0.0:
HAYSTACK_CONNECTIONS = {
'default': {
'ENGINE':'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
>>> 'URL': 'elasticsearch:9200',
'INDEX_NAME': 'haystack'
}
}
