If you manually destroy infrastructure, what is the best practice reflecting this change in Terraform?
If you manually destroy infrastructure, what is the best practice reflecting this change in Terraform?
When you manually destroy infrastructure, the best practice to reflect this change in Terraform is to run 'terraform refresh'. This command reads the current settings from all managed remote objects and updates the Terraform state to match. Note that while 'terraform refresh' is deprecated, it still serves the purpose of updating Terraform's state to reflect the manual changes made to the infrastructure. You should avoid manually updating the state file as it can introduce errors, and the changes won't happen automatically without running 'terraform refresh' or similar commands.
Wouldn't it be A?
I think is not B because automatically means that the state changes without launch commands, according to the guide you should do a plan and apply again but is not an option here so I think terraform refresh is the most feasible even if is deprecated
Refresh is deprecated and marked as unsecure. On page they write that it happens automativally. via https://developer.hashicorp.com/terraform/cli/commands/refresh
According to https://developer.hashicorp.com/terraform/cli/commands/refresh: "The -refresh-only option for terraform plan and terraform apply was introduced in Terraform v0.15.4. For prior versions you must use terraform refresh directly if you need this behavior, while taking into account the warnings above. Wherever possible, avoid using terraform refresh explicitly and instead rely on Terraform's behavior of automatically refreshing existing objects as part of creating a normal plan."
See the word "Best practice" . So the answer is B https://developer.hashicorp.com/terraform/cli/commands/refresh
The should be B Wherever possible, avoid using 'terraform refresh' explicitly and instead rely on Terraform's behavior of automatically refreshing existing objects as part of creating a normal plan. If you don't want to automatically refresh, you can use the 'terraform apply -refresh-only' without the -auto-approve option terraform refresh is deprecated https://developer.hashicorp.com/terraform/cli/commands/refresh
unless, you are using old version of TF that doesn't support the refresh-only but you shouldn't typically need to use this command, because Terraform automatically performs the same refreshing actions as a part of creating a plan in both the 'terraform plan' and ' terraform apply' commands.
Read the document carefully :-) The document mentions the reason for the deprecation and recommends alternatives. "A" is not the best practice in the real world, but is the best answer available here. "B" it won't automatically happen unless run some command.

Since Terraform does not recommend using refresh anymore, I will choose B.
if you want to just state refresh you can use "terraform apply -refresh-only" command now. terraform refresh deprecated so answer is A
of course A, although better to use command "terraform apply -refresh-only"
https://developer.hashicorp.com/terraform/cli/commands/refresh You shouldn't typically need to use this command, because Terraform automatically performs the same refreshing actions as a part of creating a plan in both the terraform plan and terraform apply commands. This command is here primarily for backward compatibility, but we don't recommend using it because it provides no opportunity to review the effects of the operation before updating the state.
->option C. We have to CHANGE the State File Manually.
Incorrect, you should not change the state file manually. The question is badly written, it does not specify if the change should take place in state or in Terraform code itself. The correct answer is not listed; remove the resource definition from your terraform code and run a terraform plan & apply, this will align the state and Terraform code with what's deployed
The phrasing makes this question really difficult... If we wish the STATE file to update, it could arguably be A or B. A is deprecated but can still run. B - if you run plan or apply, the state file WILL be automatically refreshed at the start of the run... But the question is "the best practice reflecting this change in Terraform" -- Couldn't this also mean we need the manually destroyed infrastructure to STAY destroyed? In which case.. C could be our answer (if we assume by 'manual' they mean running a state rm command")
I also think so.
Chatgpt A. Run terraform refresh Yes, in older versions of Terraform (before 0.15), terraform refresh could be used to reconcile the state file with the actual infrastructure. From Terraform 0.15 and later, terraform apply performs this reconciliation. B. It will happen automatically No, Terraform does not automatically detect changes made outside of its context. You must run terraform apply (or terraform plan in older versions) to see these changes and apply them to the Terraform state file.
The question is probably very old, posted at a time when option A was relevant and correct. It is however deprecated now and the suggested solution is "terraform apply -refresh-only". See https://developer.hashicorp.com/terraform/cli/commands/refresh
TERRAFROM plan or apply command are implicitly calling terraform refresh so when user runs the configuration file it happens automatically so I believe B is correct
A is the correct answer, I have replicated this. Created a Resource using Tf configuration Deleted it from the portal. Ran Tf Refresh, This will delete the resource details from state file.
happens automatically
terraform refresh will update only the state file. What about the configuration ?
A is correct Option . Now it is used with Terraform Plan/Apply -refresh-only option.
c'mon guys.. I am running terraform 1.3.7 and you can use either "terraform refresh" or "terraform plan -refresh-only" The problem here is that the question options is not mentioning "terraform plan -refresh-only" and the sencond problem is that if you run "terraform plan --help", you will see this: -refresh-only Select the "refresh only" planning mode, which checks whether remote objects still match the outcome of the most recent Terraform apply but does not propose any actions to undo any changes made outside of Terraform. Now let's get back on track: you create the config.. run terraform apply. .then you go to the console and delete the resource manually.. then you run "terraform plan" and it will not be aware you have deleted it.. you can check the state file and it will still be there.. So finally you run "terraform refresh" then it will remove the resource from the state file.. case closed.. Answer is Refresh.
correct answer
I guess this question is kind outdated, in this case answer is A due question's age, but nowadays answer should be B
Terraform stores the state of the infrastructure that is being created from the TF files. This state allows terraform to map real-world resources to your existing configuration. It is to be emphasized that the. tfstate file reflects actual infrastructure state including manual changes done via portal (file is kept up to date with help of terraform refresh that runs in background each time terraform plan or terraform apply is done) Prior to a plan or apply or destroy operation, terraform does a refresh to update the state file with real-world status. <<AUTOMATIC>> You can also do a refresh any time with terraform refresh.<<MANUAL>> What Terraform is doing here is reconciling the resources tracked by the state file with the real world. It does this by querying your infrastructure providers to find out what is actually running and the current configuration, and updating the state file with this new information.
Terraform is designed to co-exist with other tools as well as manually provisioned resources and so it only refreshes resources under its management. Now that the state file is up to date, Terraform can compare the desired state, defined in your configuration, with the actual state of your existing resources. This comparison allows Terraform to detect which resources need to be created, modified, or destroyed and forms a plan.
Question states "what is the best practice reflecting this change". Refreshing automatically cannot be best practice. Best practice would be run the refresh command. Though, I agree that refresh happens automatically, but I still will go with Answer A just because of the language of the question.
It is a good point you made about best practice, however the best practice would be automatic, as per Terraform page regarding the refresh: Warning: This command is deprecated, because its default behavior is unsafe if you have misconfigured credentials for any of your providers. You shouldn't typically need to use this command, because Terraform automatically performs the same refreshing actions as a part of creating a plan in both the terraform plan and terraform apply commands. This command is here primarily for backward compatibility, but we don't recommend using it because it provides no opportunity to review the effects of the operation before updating the state. As such, automatic should be the correct answer.
If you remove an EC2 instance manually and run a terraform plan/apply, it will try to recreate that instance. How can B be the answer if the instance will be recreated the next time an apply is run?

B is correct , sunte-ti prosti facuti gramada
A. Run terraform refresh
B seems more accurate than A

running "terraform refresh " to the refresh the state file
Terraform plan and apply automatically refresh the state, so B is correct.
No you deleted manuall from the Cloud, Terraform cannot notice the difference. Even if is deprecated I think you should run a refresh
A. Doesn’t make sense to directly modify the state file…
The -destroy option to terraform apply exists only in Terraform v0.15.2 and later. For earlier versions, you must use terraform destroy to get the effect of terraform apply -destroy.
A , terraform refresh is working fine
Option - A should be the Answer . Ref: https://www.terraform.io/cli/commands/refresh
A is correct answer (within scope of these answers) : refresh Best answer is described below and maybe in updated exam question.

A should be the answer here
Answer is C or A

The answer is A
the answer A tested in my lab
Answer- A. Tested in my LAB
A, tried and tested
A. Terrafrom refresh will update the state file
The only answer to this question is "refresh-only", with this option, terraform will correct your state file to match your infrastructure
A is the correct answer.
terraform import to reflect the manual deletion outside of Terraform state. refresh doesn't fix the drift. it will in fact try to recreate the infra since it's missing from the state file.
terraform import is used to get existing infra into terraform scope, if infra is removed how can you make it part of terraform, terraform refresh sync the state file with current infra state
C. Manually update the state file If you manually destroy infrastructure that was created by Terraform, the state file that Terraform uses to track the resources it manages will be out of sync with the actual infrastructure. Therefore, the best practice is to manually update the state file to reflect the changes you made. To do this, you can use the terraform state command to remove the destroyed resource from the state file. For example, if you manually deleted an EC2 instance, you can run terraform state rm aws_instance.example to remove that resource from the state file. Then, the next time you run terraform plan or terraform apply, Terraform will recognize that the resource is no longer present and will not attempt to recreate it. Option A, running terraform refresh, is not the best practice in this case, because it will only update the state file with the current state of the infrastructure, without removing the destroyed resource from the state file.
https://www.examtopics.com/exams/hashicorp/terraform-associate/view/3/
When we manual destroy our infra, we need run terraform refresh for update the terraform.tfstate
A is correct. There's no way terraform state gets updated without doing anything.
A is correct.
The terraform refresh command reads the current settings from all managed remote objects and updates the Terraform state to match. https://developer.hashicorp.com/terraform/cli/commands/refresh
I meant A,
I vote for A
Terraform refresh
A, correct
B is correct - refresh is deprecated AND unnecessary
B is correct - A is deprecated and unnecessary
When you go to do anything useful (plan or apply) the state file is automatically refreshed, so the answer should be B. More a problem of the wording of the question.
It seems to be A
A. Run terraform refresh
Due to changes in terraform versions, the answer was previously A, but is now B.
The wordings on B very unclear, while A is the closest possible answer. I would choose A over B for lack option and clarity on answers given
A is the best answer here terraform plan -refresh-only or terraform apply -refresh-only is best practice, but not mentioned here.
there are two ways to do this manually remove the resource using "terraform rm" from the state management and the other way is to refresh the state. Since the option given in this question is not clear enough as to run "terraform rm" or not in option C, I will go with option A is the best suited. terraform refresh
in the context of question resource is deleted manually mean we can just refresh the state while terrafrom rm command or manually updating state file updated than resources will be still there so I will go with a TERRAFORM REFRESH
-------------------------------
terraform refresh is not depricated. Answer is A
The command had been deprecated already. Use -refresh-only option along with terraform plan or terraform apply for the same operation.
A is the correct answer. Terraform says Warning: This command is deprecated, because its default behavior is unsafe if you have misconfigured credentials for any of your providers. You shouldn't typically need to use this command, because Terraform automatically performs the same refreshing actions as a part of creating a plan in both the terraform plan and terraform apply commands.
he terraform refresh command : You shouldn't typically need to use this command, because Terraform automatically performs the same refreshing actions as a part of creating a plan in both the terraform plan and terraform apply commands.
terraform refresh is used to reconcile the Terraform state with the real-world infrastructure. If you manually destroy infrastructure, the Terraform state will still show that the resource exists. Running terraform refresh updates the state to reflect the current state of the infrastructure, marking resources that were manually destroyed as no longer existing. B. It will happen automatically: No, Terraform does not automatically update its state when infrastructure is changed outside of Terraform. You need to run a command like terraform refresh.
Answer is C. We have to manually remove the the resource from state file.
The best practice when infrastructure is manually destroyed is to manually update the state file (option C). This means the need to update Terraform's state file to reflect that the resource has been destroyed outside of Terraform. Specifically: You can use the terraform state rm command to remove the resource from the state file, as it no longer exists. Alternatively, you could manually edit the state file, but this is risky and generally not recommended. Other options like terraform refresh will only update the state based on the existing infrastructure, but if the resource was destroyed outside of Terraform, it will still appear in the state file unless manually removed.
A. is correct but now as a best practice the correct way should be running terraform apply with the -refresh-only, this way you will get a prompt when it compares and see's that the deleted infrastructure is missing and will show you during your plan.
When infrastructure is manually destroyed (outside of Terraform): 🔄 Terraform's state file becomes out of sync with reality 🎯 terraform refresh updates the state file to match the real infrastructure 📝 No changes are made to your infrastructure, only to the state file Why it's not "C": - Dangerous practice - Easy to corrupt state file - Can cause inconsistencies - Not recommended
"Manually destroying infrastructure" means you changed infrastructure outside of Terraform. What is the best practice reflecting this change in your* Terraform configuration*? Correct Anwser is [A] : Run terraform refresh (Answer B is wrong: Because a manual change in remote infrastructure is not automatically parsed into your Terraform configuration)
