# Elasticsearch Helm Chart
2+
3+
This chart installs a working version of Elasticsearch cluster on Kubernetes.
4+
5+
### Installation
6+
7+
Values.yaml contains configuration for Elasticsearch cluster.
8+
9+
#### Note: Minimum of 2 Master Nodes are required for elasticsearch cluster
10+
11+
```
12+
helm install elasticsearch
13+
14+
```
15+
### To verify the helm deployment was successful:
16+
17+
```
18+
helm list
19+
```
20+
21+
### To confirm all pods are up and running:
22+
23+
```
24+
kubectl get pods
25+
26+
```
27+
28+
### To view list of services
29+
30+
```
31+
kubectl get svc
32+
```
33+
34+
```
35+
elasticsearch-discovery 10.99.148.252 <none> 9300/TCP 47m
36+
elasticsearch-logging 10.105.222.126 <pending> 9200:31070/TCP 47m
37+
```
38+
39+
### Test elasticsearch functionality:
40+
41+
#### From any host within cluster..
42+
43+
1) Check if Elasticsearch cluster is up
44+
```
45+
curl http://10.105.222.126:9200
46+
```
47+
```
48+
curl http://10.105.222.126:9200/_cluster/health?pretty
49+
```
50+
51+
2) Store data manually using APIs
52+
```
53+
curl -XPUT 'http://10.105.222.126:9200/blog/user/renmak' -d \
54+
'{ "name" : "Dilbert Brown" }'
55+
```
56+
```
57+
curl -XPUT 'http://10.105.222.126:9200/blog/post/1' -d \
58+
'{ "user":"renmak", "title":"how to test ES"}'
59+
```
60+
3) Retrive data manually using APIs
61+
```
62+
curl -XGET 'http://10.105.222.126:9200/blog/user/renmak?pretty=true'
63+
64+
curl -XGET 'http://10.105.222.126:9200/blog/post/1?pretty=true'
65+
66+
curl -XGET 'http://10.105.222.126:9200/blog/post/_search?q=user:renmak&pretty=true'
67+
68+
curl -XGET 'http://10.105.222.126:9200/_search?q=*renmak&pretty=true'
