Batch tokens are generally used for encrypting data because they are lightweight and scalable and also include enough information to use with Vault.

To extend Vault beyond a data center or cloud regional boundary, replication can be used. Vault supports both DR replication and Performance replication to copy data from the primary cluster to a secondary cluster safely.

By default, Terraform will clone and use the default branch (referenced by HEAD) in the selected repository. You can override this using the ref argument:

module "vpc" {source = "git::https://wpexpertsupport.com/vpc.git?ref=v1.2.0 "}

The value of the ref argument can be any reference that would be accepted by the git checkout command, including branch and tag names.

Dev server mode stores its data in memory, therefore if the Vault service is shut down, any data stored will be lost. Additionally, dev server mode does not use TLS, and all data is sent in cleartext.

A workspace can only be configured to a single VCS repo, however, multiple workspaces can use the same repo, if needed. A good Explanation: of how to configure your code repositories can be found here.

The -prefix flag treats the ID as a prefix instead of an exact lease ID. This can revoke multiple leases simultaneously.

For production use, you should constrain the acceptable provider versions via configuration file to ensure that new versions with breaking changes will not be automatically installed by terraform init in the future. When terraform init is run without provider version constraints, it prints a suggested version constraint string for each provider

For example:

terraform {

required_providers {

aws = ">= 2.7.0"

}

}

The terraform workspace select command is used to choose a different workspace to use for further operations. https://www.terraform.io/docs/commands/workspace/select.html

The storage stanza configures the storage backend, which represents the location for the durable storage of Vault's information.

Storage backend configuration is done through the Vault configuration file using the storage stanza.

The kv delete command is like a soft delete which deletes the data for the provided path in the key/value secrets engine. If using K/V Version 2, its versioned data will not be fully removed, but marked as deleted and will no longer be available for normal get requests.

The kv destroy command permanently removes the specified versions' data from the key/value secrets engine. If no key exists at the path, no action is taken. It does not deletes all versions of a secret.

The kv metadata delete command deletes all versions and metadata for the provided key.
