Despite the fact that the Terraform cache is automatically cleared before each deployment, you may also want to manually force the cleaning process. To clear the Terraform cache, Run the
ansible-playbook clean.yml command.
You can easily manipulate your deployment from any machine with sufficient prerequisites. If the
upload_debug_info_to_s3 variable is set to true, the deployer will automatically upload your
all.yml file to the s3 bucket, so you can download it to any other machine. Simply download this file to your
group_vars folder and your new deployer will pick up the current deployment instead of creating a new one.
Rather than create a new database, you may want to add an existing instance to use with the deployment. To do this, configure all proper values at
group_vars/all.yml, including your DB ID and name, and execute the
ansible-playbook attach_existing_rds.yml command. This will add the current DB instance into the Terraform-managed resource group. After that run
ansible-playbook deploy_infra.yml as you normally would.
ansible-playbook attach_existing_rds.yml the S3 and DynamoDB instances will be automatically created (if
backend variable is set to
true) to store Terraform state files.
The actual name of your resource must include the prefix you are using with this deployment.
Real resource: tf-poa
prefix variable: tf
chain_db_id variable: poa
Make sure MultiAZ is disabled on your database.
Make sure that all the variables at
group_vars/all.yml are exactly the same as your existing DB.
BlockScout deployment can be managed through the AWS console. A brief tutorial is available on our forum.
