Django setup elasticsearch client with password auth - django

Question

My Django application uses elasticsearch to index several ressources.
Now I wanted to protect my elasticsearch instance with as password which is working fine if I use "curl -u" or so. Anyways from the elasticsearch_dsl documentation, found here: https://elasticsearch-dsl.readthedocs.io/en/latest/configuration.html, I do not understand what I have to do in order to setup elasticsearch that way that it uses a password for authentication and where do I have to place this code?! is smb. maybe able to pass show me some snippets of his configuration?
My current state looks like this:
settingy.py
ELASTICSEARCH_DSL = {
'default': {
'hosts': env.str('ELASTICSEARCH_HOST') + str(':') + env.str('ELASTICSEARCH_PORT'),
},
}
ELASTICSEARCH_DSL_SIGNAL_PROCESSOR = 'django_elasticsearch_dsl.signals.RealTimeSignalProcessor'
documents.py
from django_elasticsearch_dsl import Document, Index, fields
from elasticsearch_dsl import analyzer
from App.models import Post
# elasticsearch index
posts = Index('posts')
html_strip = analyzer(
'html_strip',
tokenizer="standard",
filter=["lowercase", "stop", "snowball"],
char_filter=["html_strip"]
)
#posts.document
class PostDocument(Document):
... more index stuff
According to the docs, I have to manually setup a default client connection where I can also pass the password and username for authentication which to me seems not to be possible at settings.py at moment.
Kind regards

You can pass the elasticsearch URL as
from urllib.parse import quote_plus as urlquote
elk_base_url = 'elasticsearch://{user_name}:{password}#{host_ip}:{host_port}'
elastic_search_url = elk_base_url.format(user_name='my_username',
password=urlquote('mysecret_password'),
# password may contain special characters
host_ip='my-elastic-host-ip',
host_port=9200)
ELASTICSEARCH_DSL = {
'default': {
'hosts': [elastic_search_url]
},
}
This solution has been tested under the following circumstances
Django==3.0.4
django-elasticsearch-dsl==7.1.1
logstash == kibana == elasticsearch == 7.6.0
If you are experiencing AuthenticationException(401, '') exception, it means you were provide the wrong credentials. Please do check the value of elastic_search_url and make sure the values are correct.
