I've been trying to use python's elasticsearch library to connect to my ElasticSearch host machine. So the code looks like:
client = Elasticsearch(
["https://my-machine.io:9200"],
http_auth=("user", "password")
)
Now the problem is that this instruction is only working when I use the python 2.7 interpreter, while it fails with python 3.6, generating the following error:
File "/usr/local/lib/python3.6/site-packages/elasticsearch/client/__init__.py", line 171, in __init__
self.transport = transport_class(_normalize_hosts(hosts), **kwargs)
File "/usr/local/lib/python3.6/site-packages/elasticsearch/transport.py", line 108, in __init__
self.set_connections(hosts)
File "/usr/local/lib/python3.6/site-packages/elasticsearch/transport.py", line 163, in set_connections
connections = list(zip(connections, hosts))
File "/usr/local/lib/python3.6/site-packages/elasticsearch/transport.py", line 160, in _create_connection
return self.connection_class(**kwargs)
File "/usr/local/lib/python3.6/site-packages/elasticsearch/connection/http_urllib3.py", line 78, in __init__
raise ImproperlyConfigured("Root certificates are missing for certificate "
elasticsearch.exceptions.ImproperlyConfigured: Root certificates are missing for certificate validation. Either pass them in using the ca_certs parameter or install certifi to use it automatically.
Python versions:
$ python2 --version
Python 2.7.13
$ python3 --version
Python 3.6.1
In both cases I'm using the "elasticsearch" package, version 5.3.0
I've not been able to find any piece of documentation that would suggest a different behaviour based on the version of python being used. Could anyone explain why is this happening?
It looks like the problem is in your ssl setup, make sure you have certifi installed which will provide the root certificates needed.
