Destroying Provisioned Infrastructure
Deployment with Terraform 12 is unstable due to these bugs: #144, #147, #148, #149. Please use TF 11.11 - 11.14 and following branch for deployment https://github.com/poanetwork/blockscout-terraform/tree/before-t12
First, remove autoscaling groups (ASG) deployed via CodeDeploy manually since Terraform doesn't track them and will miss them during the automatic destroy process. Once ASG is deleted you can use the
ansible-playbook destroy.ymlplaybook to remove the rest of the generated infrastructure.
Make sure to check the playbook output since in some cases it may not delete everything. Check the error description for details.
While Terraform is stateful, Ansible is stateless, so if you modify
dynamodb_tablevariables and run
deploy_infra.ymlplaybooks, it will not alter the current S3/Dynamo resources names, but create new resources. Moreover, altering the
bucketvariable will make Terraform forget about existing infrastructure and, as a consequence, redeploy it. If it is absolutely necessary for you to alter the S3 or DynamoDB names, perform this operation manually and then change the appropriate variable accordingly.
backendvariable will force Terraform to forget about created infrastructure, since it will start searching the current state files locally instead of remotely.
