It implies that there is a syntax error in the configuration file. The exact location of the error in the file can be identified in the error message

The terraform state command is used for advanced state management. Rather than modify the state directly, the terraform state commands can be used in many cases instead.

Terraform is a cloud-agnostic tool, and therefore isn't limited to a single cloud provider, such as AWS CloudFormation or Azure Resource Manager. Terraform supports all of the major cloud providers and allows IT organizations to focus on learning a single tool for deploying its infrastructure, regardless of what platform it's being deployed on.

The Consul agent is the core Consul process that runs the Consul service. Everything Consul does is the result of the Consul agent, which can run in either server or client mode.

The vault operator init command initializes a Vault server. Initialization is the process by which Vault's storage backend is prepared to receive data.

This only happens once when the server is started against a new backend that has never been used with Vault before.

Within each datacenter, we have a mixture of clients and servers. It is expected that there be between three to five servers. This strikes a balance between availability in the case of failure and performance, as consensus gets progressively slower as more machines are added. However, there is no limit to the number of clients, and they can easily scale into the thousands or tens of thousands.

Server or Leader - It indicates whether the agent is running in server or client mode. Server nodes participate in the consensus quorum, storing cluster state, and handling queries. At any given time, the peer set elects a single node to be the leader. The leader is responsible for ingesting new log entries, replicating to followers, and managing when an entry is considered committed.

Client or Follower - Client nodes make up the majority of the cluster, and they are very lightweight as they interface with the server nodes for most operations and maintain a very little state of their own.

The terraform taint command manually marks a Terraform-managed resource as tainted, forcing it to be destroyed and recreated on the next apply. This command will not modify infrastructure but does modify the state file in order to mark a resource as tainted. Once a resource is marked as tainted, the next plan will show that the resource will be destroyed and recreated. The next terraform apply will

implement this change.

All plaintext data must be base64-encoded. The reason for this requirement is that Vault does not require that the plaintext is "text". It could be a binary file such as a PDF or image. The easiest safe transport mechanism for this data as part of a JSON payload is to base64-encode it.

The Identity secrets engine is the identity management solution for Vault. It internally maintains the clients who are recognized by Vault. This secrets engine will be mounted by default. This secrets engine cannot be disabled or moved.

The Vault server process collects various runtime metrics about the performance of different libraries and subsystems. These metrics are aggregated on a ten-second interval and are retained for one minute. This telemetry information can be used for debugging or otherwise getting a better view of what Vault is doing.

Telemetry information can be streamed directly from Vault to a range of metrics aggregation solutions as described in the telemetry Stanza documentation.
