# Infrastructure changelog ## Changelog #### 13.03.2022 What has been done: - recreated Opensearch cluster - resize storage from 50GB to 1TB - changed cloudformation stack name from opensearchteststack to opensearchstack, - added security rule that allows logscraper01.openstack.org to push logs to the Logstash service, - renamed Logstash container service deployment from pre-prod-Cluster to production-Cluster. Executed commands: ``` shell # Delete stacks if they exist echo "Deleting Logstash stack..." aws cloudformation delete-stack --stack-name logstashstack echo "Waiting 60 minutes (press enter to continue)..." read -t 3600 NullVariable echo "Deleting Opensearch stack..." aws cloudformation delete-stack --stack-name opensearchteststack echo "Waiting 60 minutes (press enter to continue)..." read -t 3600 NullVariable # Create OpenSearch Cluster stack echo "" echo "Creating Opensearch stack..." aws cloudformation create-stack --stack-name opensearchstack --template-body file://opensearch.yaml --parameters ParameterKey=SSHKey,ParameterValue=my-keypair --capabilities CAPABILITY_NAMED_IAM echo "Waiting 60 minutes (press enter to continue)..." read -t 3600 NullVariable # Create Logstash Cluster stack aws cloudformation create-stack --stack-name logstashstack --template-body file://logstash_cluster.yaml --capabilities CAPABILITY_NAMED_IAM ``` Different changes to CloudFormatino templates have different "update behaviors". For example, changing the EBS configuration of an OpenSearch cluster requires "No interruption" ([source](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-opensearchservice-domain.html#cfn-opensearchservice-domain-ebsoptions)). Others (like changing the name of a CloudFormation stack or a load balancer) require total replacement. Those update behaviors are documented [here](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html). If you're deploying a change that doesn't require resource replacement, you can run the "update-stack" commands: ```shell aws cloudformation update-stack --stack-name opensearchstack --template-body file://opensearch.yaml --parameters ParameterKey=SSHKey,ParameterValue=my-keypair --capabilities CAPABILITY_NAMED_IAM aws cloudformation update-stack --stack-name logstashstack --template-body file://logstash_cluster.yaml --capabilities CAPABILITY_NAMED_IAM ``` #### 15.12.2021 What has been done: - creted cloudformation stack for Logstash, - created Opensearch cluster, - created readonly user and readonly role, - deployed logscraper, loggearman-client and loggearman-worker services on logscraper01.openstack.org. Configuration has been describe `here `__.
