Step 1 — Remote State with Storage Account . Storage Encryption Scopes can be imported using the resource id, e.g. Change ), You are commenting using your Facebook account. 4. Change ). Locking helps in preventing conflicts, data loss and state file corruption due to multiple runs on the same state file. To enable Terraform to use this information, you need to copy some of the above command’s output: Now you can configure environmental variables for Terraform with the information above and either export the following environment variables or configure a Terraform provider: To export the variables you run the code above in you bash shell session or store it in your ./bash_profile file (on macOS). the ability to change existing deployments. DynamoDB supports state locking and consistency checking. Storage Encryption is now enabled by default, but you should make sure it is enabled, and if you want to use your own key … However, S3 doesn’t support the state locking functionality and this can be achieved by using DynamoDB. To set up the resource group for the Azure Storage Account, open up an Azure Cloud Shell session and type in the following command: A workaround is to use a null_resource to enable these settings (e.g. Adds the Azure Storage Account key as a pipeline variable so that we can use it in the next task; If the Resource Group, Azure Storage Account and container already exist then we still need the Azure Storage Account key so this task needs to be executed during each pipeline run as the following task needs to interact with the Azure Storage account: Data in Azure Storage is encrypted and decrypted transparently using 256-bit AES encryption, one of the strongest block ciphers available, and is FIPS 140-2 compliant. In today’s multi cloud environment, it is beneficial to use automation patterns you can repeat across multiple environments. the following passage is an Azure CLI script to create the service principal which is used for Terraform later: ARM_SUBSCRIPTION_ID=yourSubscriptionID Change ), You are commenting using your Twitter account. I have created an Azure Key Vault secret with the storage account key as the secret’s value and then added the following line to my .bash_profile file: The export command creates an environment variable for as long as the bash terminal is running.

A “backend” in Terraform determines the handling of the state and the way certain operations are executed, enabling many essential features. Next, we need to get the storage account key for our new SA. Identity Identity The identity of the resource. Set the tags on the storage account to use the tags exported attribute of the azurerm_resource_group; Prefix the storage account name with the value of the source tag; Rerun the terraform plan; If you get stuck on this section then you can skip to the end of the lab and click on the terraform … The Terraform top level keyword is resource. The following bash code creates the new Azure resource group terraformstate and a new storage account with a random name in it: Now, you have a storage account and a storage container and you need to make Terraform using this container as a remote backend. The storage account name forms part of the FQDN, and needs to be globally unique; Save the file (CTRL+S) The round dot on the file name tab denotes unsaved changes; Let’s look more closely at the second resource block (or stanza) for the storage account.
