Hi guys,
in my company we started using Terraform with New Relic provider in order to be maintain, reuse, deploy our monitoring checks. I never myself used it before but I tried to read as more documentation as possible. Just saying this propaedeutic to let you know that might be simply be caused by an improper usage of Terraform modules as I am a newbie 
.
Terraform Version
v0.13.2
Newrelic Version
v2.7.5
Affected Resource(s)
- newrelic_synthetics_monitor
- newrelic_synthetics_monitor_script
- newrelic_alert_policy
- newrelic_nrql_alert_condition
- newrelic_alert_channel
Terraform Configuration Files
Attaching source code of the PROJECT.zip which is pretty simple. This way you should be able to reproduce the problem which includes:
- check1 which is a Synthetic check API based
- check2 which is a Synthetic check browser based
Expected Behavior
When check 1 is live (which means I’ve run terraform apply <DIRECTORY_CHECK1>) I should be able to deploy check 2 (terraform apply <DIRECTORY_CHECK2>) without destroying the resources of check 1 which are not in check 2 as I am using terraform apply <PATH>. For an unknown reason its seems it’s doing a kind of bisect.
Actual Behavior
By applying check 1 in a workspace called “staging”, when I
- init
- plan
- apply
check 2 then check 1’s resources should not removed.
Steps to Reproduce
$ terraform workspace new staging
$ terraform workspace select staging
$ terraform init ./check1
$ terraform plan ./check1
$ terraform apply ./check1

Note.
as far as I read it’s possible to apply a single directory or to use target option. I tried both but got the same behavior in both cases.
Could you please help me?
Best
