How to get a list of all indexes in python-elasticsearch
PythonElasticsearchPython Problem Overview
How would I get a list of the names of an index in Python? Here is what I have so far:
>>> es=e.es
>>> es
<Elasticsearch([{'host': '14555f777d8097.us-east-1.aws.found.io', 'port': 9200}])>
>>> es.indices
<elasticsearch.client.indices.IndicesClient object at 0x10de86790>
# how to get a list of all indexes in this cluster?
Python Solutions
Solution 1 - Python
This question comes up when searching for information on retrieving aliases using the python-elasticsearch library. The accepted answer says to use get_aliases but that method has been removed (as of 2017). To get aliases, you can use the following:
es.indices.get_alias("*")

>how to get a list of all indexes in this cluster?
Use the wildcard. Works with elasticsearch-py.
for index in es.indices.get('*'):
print index
Solution 3 - Python
Here is one way to do it with the get_alias() method:
>>> indices=es.indices.get_alias().keys()
>>> sorted(indices)
[u'avails', u'hey', u'kibana-int']
Solution 4 - Python
If you are willing to use pyelasticsearch module they have support for the GET _mapping command, which produces the schema of the cluster. This will allow you to see the indices, and drill into each index to see doc_types, and their fields, etc. Here's an example:
import pyelasticsearch as pyes
es = pyes.ElasticSearch(["http://hostname0:9200", "http://hostname1:9200"]) ## don't accidentally type Elasticsearch, the class from the other two modules
schema = es.get_mapping() ## python dict with the map of the cluster
To get just the list of indices,
indices_full_list = schema.keys()
just_indices = [index for index in indices_full_list if not index.startswith(".")] ## remove the objects created by marvel, e.g. ".marvel-date"

Solution 5 - Python
I use curl to call the stats API and get information about the indices. Then I parse the JSON object that is returned to find the index names.
curl localhost:9200/_stats
In Python you can call curl using the requests library. I don't know of a way to do this using the Elasticsearch or Elasticsearch-DSL Python library.
Solution 6 - Python
You can get _mapping to get list of all indexes by doing something like that.
requests.get(full_elastic_url + "/_mapping")
Solution 7 - Python
You can use the Cat API:es.cat.indices(h='index', s='index').split()
Solution 8 - Python
If you want 'alias name' and not 'index name', here the perfect solution:
response = es.indices.get(indexname)
alias_names = list(response[indexname]['aliases'].keys())
In alias_names we get list of alias names on a particular index.
