The storage folder must already exist. - **No High Availability** – the Manta storage backend does not support high availability. - **Community Supported** – the Manta storage backend is supported by the community. While it has undergone review by HashiCorp employees, they may not be as knowledgeable about the technology. If you encounter problems with them, you may be referred to the original author. ```hcl storage "manta" { directory = "manta-directory" user = "myuser" key_id = "40:9d:d3:f9:0b:86:62:48:f4:2e:a5:8e:43:00:2a:9b" } ``` ## `manta` Parameters - `directory` `(string: )` – Specifies the name of the manta directory to use. This will be in the `/stor/` folder in the specific manta account The following settings are used for authenticating to Manta. - `user` `(string: )` – Specifies the Manta user account name. This can also be provided via the environment variable `MANTA_USER`. - `key_id` `(string: )` – The fingerprint of the public key of the SSH key pair to use for authentication with the Manta API. It is assumed that the SSH agent has the private key corresponding to this key ID loaded. This can also be provided via the environment variable `MANTA_KEY_ID`. - `subuser` - The name of a subuser that has been granted access to the Manta account. This can also be provided via the environment variable `MANTA_SUBUSER`. - `url` – Specifies the Manta URL. Defaults to `https://us-east.manta.joyent.com`. This can also be provided via the environment variable `MANTA_URL`. - `max_parallel` `(string: "128")` – Specifies The maximum number of concurrent requests to Manta. ## `manta` Examples This example shows configuring the Azure storage backend with a custom number of maximum parallel connections. ```hcl storage "manta" { directory = "vault-storage-directory" max_parallel = 512 } ``` [manta-object-store]: https://www.joyent.com/triton/object-storage
