About
This folder contains CloudFormation configurations for an AWS OpenSearch cluster and a set of Logstash servers behind a load balancer.
Usage
You'll need appropriate AWS permissions (to create and monitor resources). Put AWS credentials in ~/.aws/credentials and run deploy_opensearch.sh.
After Creation
OpenSearch users
- Create a user with username 'logstash' and the entered password in OpenSearch, and assign it the "logstash" role.
- Create a user with username 'readonly' and password 'opensearch-readonly-PUBLIC-2021!' in OpenSearch, and grant it read-only privileges. Give it access to the Global tenant.
In the OpenSearch Dashboard select Index Management, State management policies, and then Create Policy. Make a policy with the following policy statement:
{
"policy_id": "DeleteAllDataAfter14Days",
"description": "Delete all data after 14 days",
"last_updated_time": 1639608774297,
"schema_version": 1,
"error_notification": null,
"default_state": "hot",
"states": [
{
"name": "hot",
"actions": [],
"transitions": [
{
"state_name": "delete",
"conditions": {
"min_index_age": "14d"
}
}
]
},
{
"name": "delete",
"actions": [],
"transitions": []
}
],
"ism_template": null
}
This will delete all indices that are at least 7 days old (e.g. the logstash-logs-2021.12.15 index will be deleted on 2021-12-22).
