![]() In our example, the only attribute that causes replacement is the AMI ID. Observe the plan output, and find all those attributes which cause the replacement. Eventually, you would achieve a state of 0 difference. ![]() Right now, you need to focus on not replacing the given EC2 instance, but rather aligning the configuration so that the replacement can be avoided. The use of the word “minimum” is intentional here. You need to investigate the state file and update your configuration accordingly so that there is a minimum difference between them. All of its future operations are performed with consideration for this state file. However, the Terraform team is working hard to improve this function in upcoming releases.Īt this point, it is important to understand that the terraform.tfstate file is a vital piece of reference for Terraform. ![]() ![]() The import functionality helps update the state locally and it does not create the corresponding configuration automatically. import is a Terraform CLI command which is used to read real-world infrastructure and update the state, so that future updates to the same set of infrastructure can be applied via IaC. Getting the pre-existing cloud resources under the Terraform management is facilitated by Terraform import. Luckily, you can use the import functionality to rebuild it. In a worst case scenario, you can lose the terraform.tfstate file. Things get especially complicated when dealing with concepts like states and remote backends. The lack of human resources and the steep learning curve involved in using Terraform effectively causes teams to start using cloud infrastructure directly via their respective web consoles.įor that matter, any kind of IaC method (CloudFormation, Azure ARM templates, Pulumi, etc.) requires some training and real-time scenario handling experience. Terraform is a relatively new technology and adopting it to manage an organisation’s cloud resources might take some time and effort.
