[PSA] bei-common-libraries Log Setting Changes

TL;DR

All features about CloudWatch log management features (such as log group creation and log retention period update) have been removed in the latest versions of bei-common-libraries (v11.1.42 and v11.2.48).
Migrate your log group configuration (including your custom-defined log group) into Terraform code.

Background

Having a standard log retention period of 1 year is one of the priorities for our IPO preparation. Currently, we have two options to manage log, using bei-common-libraries and Terraform. It creates confusion about where to put the configuration.

In addition, we want to standardize our log management procedure using Terraform as a part of the IaC (Infrastructure as Code) policy.

Release Notes

Existing Applications (Log groups already exist)

(If you decide to upgrade your bei-common-libraries to the latest version (you should))

Create Terraform code for managing cloudwatch log groups (including your custom-defined log group). Why? We must ensure no missing state for log group creation and retention.

Example: https://github.com/traveloka/terraform-aws-cul-stack-modules/blob/master/culdata-app/cw-log.tf

Import the existing CloudWatch log groups resources into Terraform state.

Example:
terraform import module.culdata_app.aws_cloudwatch_log_group.api_access_log /tvlk/app-java/culdata/api_access.log

Upgrade your bei-common-libraries version to either:

>= v11.2.48
>= v11.1.42

If you have a logRetentionPeriodInDays parameter in your @TravelokaApplication annotation, we encourage you to remove it because this parameter is not used anymore. We will remove the parameter in future releases.

Removable code example: https://github.com/traveloka/lpc-quotation/blob/d9b5214ef2053f2df510f50276685ec86d3c79d8/pricing-service/src/main/java/com/traveloka/lpc/pricing/component/PricingServiceComponent.java#L22-L24 (remove logRetentionPeriodInDays part)

New Applications

(If you decide to use the latest version of bei-common-libraries (you should))

Create Terraform code for log group creation (including your custom-defined log group).

Example: https://github.com/traveloka/terraform-aws-cul-stack-modules/blob/master/culdata-app/cw-log.tf

That's all for the announcement. Thank you for your attention.
