Elasticsearch #
Defining a Resource #
INFINI Gateway supports multi-cluster access and different versions. Each cluster serves as one Elasticsearch back-end resource and can be subsequently used by INFINI Gateway in multiple locations. See the following example.
elasticsearch:
- name: local
enabled: true
endpoint: https://127.0.0.1:9200
- name: dev
enabled: true
endpoint: https://192.168.3.98:9200
basic_auth:
username: elastic
password: pass
- name: prod
enabled: true
endpoint: http://192.168.3.201:9200
discovery:
enabled: true
refresh:
enabled: true
interval: 10s
basic_auth:
username: elastic
password: pass
The above example defines a local development test cluster named local
and a development cluster named dev
.
Authentication is enabled in the development cluster, in which corresponding usernames and passwords are also defined. In addition, one production cluster named prod
is defined, and the auto node topology discovery and update of the cluster are enabled through the discovery
parameter.
