Since 4.0.0 the ASG name is used to fill the EC2 "Name" tag

[gmconte]

Description

since version 4.0.0 the variable asg_name has been removed. This was very useful to separate the name of the ASG from the variable name, which is included as tag "Name" and propagated to the EC2 instances. Now, the only variable we can use is name which means that I need to either change the name of my ASG (and the Cloudwatch metrics, alarms, etc associated) or let the new version change the Name tag of my EC2 instances (and so all the EC2 Cloudwatch metrics, alarms, etc).

I can't set the "Name" tag anywhere because it gets randomly overwritten by the hardcoded "Name" tag when the code builds the local.tags variable in main.tf, so there's no workaround unless I modify my user_data to change the tag from the instance itself.

Reproduction

Steps to reproduce the behavior: Configure ASG in version 3.9.0 set the variables:

• name
• asg_name

now upgrade to version 4.x.x

Expected behavior

naming of ASG should be separate from the name tag propagated to the EC2 instances. In 3.9.0 this meant accepting that the ASG had the same Name tag as the EC2, which is ok.

Actual behavior

The asg_name variable is not valid anymore I have to either change the Name tag of the EC2 instance or the ASG name

Possible solutions:

• reinstate the asg_name variable or
• allow overriding the tag "Name" that is hardcoded in the local.tags in main.tf
