To remove/terminate or destroy a build, it pretty simple. You use the terraform destroy command
ayan@Epoch:~/terraform$ terraform destroy aws_instance.example: Refreshing state... (ID: i-065b6f952bd9dc3e0) An execution plan has been generated and is shown below. Resource actions are indicated with the following symbols: - destroy Terraform will perform the following actions: - aws_instance.example Plan: 0 to add, 0 to change, 1 to destroy. Do you really want to destroy all resources? Terraform will destroy all your managed infrastructure, as shown above. There is no undo. Only 'yes' will be accepted to confirm. Enter a value: yes aws_instance.example: Destroying... (ID: i-065b6f952bd9dc3e0) aws_instance.example: Still destroying... (ID: i-065b6f952bd9dc3e0, 10s elapsed) aws_instance.example: Still destroying... (ID: i-065b6f952bd9dc3e0, 20s elapsed) aws_instance.example: Still destroying... (ID: i-065b6f952bd9dc3e0, 30s elapsed) aws_instance.example: Still destroying... (ID: i-065b6f952bd9dc3e0, 40s elapsed) aws_instance.example: Still destroying... (ID: i-065b6f952bd9dc3e0, 50s elapsed) aws_instance.example: Still destroying... (ID: i-065b6f952bd9dc3e0, 1m0s elapsed) aws_instance.example: Still destroying... (ID: i-065b6f952bd9dc3e0, 1m10s elapsed) aws_instance.example: Destruction complete after 1m19s Destroy complete! Resources: 1 destroyed.
Destroying the infrastructure does not automatically remove the source files though
ayan@Epoch:~/terraform$ ls -lrth total 12K -rwxrwxrwx 1 ayan ayan 243 Jan 3 18:00 aws.tf -rw-rw-r-- 1 ayan ayan 3.9K Jan 4 15:17 terraform.tfstate.backup -rw-rw-r-- 1 ayan ayan 319 Jan 4 15:17 terraform.tfstate
But it does change the state file
{ "version": 3, "terraform_version": "0.11.11", "serial": 10, "lineage": "0bda5f62-cdfc-ca79-284f-XXXX", "modules": [ { "path": [ "root" ], "outputs": {}, "resources": {}, "depends_on": [] } ] }
The backup file still has the previous data in case it is needed
