The storage folder must already exist. 16 17- **No High Availability** – the Manta storage backend does not support high 18 availability. 19 20- **Community Supported** – the Manta storage backend is supported by the 21 community. While it has undergone review by HashiCorp employees, they may not 22 be as knowledgeable about the technology. If you encounter problems with them, 23 you may be referred to the original author. 24 25```hcl 26storage "manta" { 27 directory = "manta-directory" 28 user = "myuser" 29 key_id = "40:9d:d3:f9:0b:86:62:48:f4:2e:a5:8e:43:00:2a:9b" 30} 31``` 32 33## `manta` Parameters 34 35- `directory` `(string: <required>)` – Specifies the name of the manta directory to use. 36 This will be in the `/stor/` folder in the specific manta account 37 38The following settings are used for authenticating to Manta. 39 40- `user` `(string: <required>)` – Specifies the Manta user account name. This can also be provided via 41 the environment variable `MANTA_USER`. 42 43- `key_id` `(string: <required>)` – The fingerprint of the public key of the SSH key pair to use for authentication with the Manta API. 44 It is assumed that the SSH agent has the private key corresponding to this key ID loaded. This can also be provided 45 via the environment variable `MANTA_KEY_ID`. 46 47- `subuser` - The name of a subuser that has been granted access to the Manta account.
