Hi !
I need a suggestion from you to solve a problem I'm facing, here it is...
The problem:
I have a ElasticSearch cluster composed of 6 nodes. During the non work
hours I would like to substitute 4 of those 6 ec2 instance for a different
server (cheaper instance). The main problem is: How can I proceed to the
next server , and remove it from the cluster, since I must wait for the
cluster to get in the "green state" ?
Below you can see how I stop the instances:
- name: Stopping ES
ec2:
instance_ids: "{{ item }}"
region: sa-east-1
state: stopped
wait: True
with_items: es_ids
tags:
- esi_stop
and how I run the cluster health check:
- name: Checking ES Cluster Status
uri:
url=http://<cluster_address>:9200/_cluster/health?pretty
method=GET
status_code=200
register: cluster_status
until: "'{{ cluster_status.json.status }}' == 'green'"
retries: 5
delay: 30
tags:
- check_cluster_status
Thanks in advance!
