[Feature Request] Ability to specify CloudWatch Log group name for VPC Flow logs

[air3ijai]

Is your request related to a problem? Please describe.

As for now, we can specify just flow_log_cloudwatch_log_group_name_prefix and with all defaults we will get a kind of the the following name for CloudWatch Log group name:

/aws/vpc-flow-log/vpc-02b7411f86f26842b

Describe the solution you'd like.

We should be able to specify CloudWatch Log group name(suffix) in order to be able to identify it by name.

A variable like flow_log_cloudwatch_log_group_name = project-name should permit us to set custom name instead of VPC ID:

/aws/vpc-flow-log/project-name

Current code

terraform-aws-vpc/vpc-flow-logs.tf

Line 47 in 5939699

name = "${var.flow_log_cloudwatch_log_group_name_prefix}${local.vpc_id}"

this is not a naming scheme we control - its a naming scheme controlled by AWS that we match here in order to "control" the log group

Not sure if I understand correctly - we cannot do this or we should not do this?

I just updated code to test how it works

  name              = "${var.flow_log_cloudwatch_log_group_name_prefix}projects-name"

I was trying to find the documentation but I stand corrected - I guess we do have control over the log group name. A lot of other services usually dictate the name of the log group but I guess VPC flow logs allows complete control of the name
