### Service "container.Service"
|
||
|
|
Container service provides API for manipulating with the container.
|
||
|
|
|
||
|
|
```
|
||
|
|
rpc Put(PutRequest) returns (PutResponse);
|
||
|
|
rpc Delete(DeleteRequest) returns (DeleteResponse);
|
||
|
|
rpc Get(GetRequest) returns (GetResponse);
|
||
|
|
rpc List(ListRequest) returns (ListResponse);
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Method Put
|
||
|
|
|
||
|
|
Put request proposes container to the inner ring nodes. They will
|
||
|
|
accept new container if user has enough deposit. All containers
|
||
|
|
are accepted by the consensus, therefore it is asynchronous process.
|
||
|
|
|
||
|
|
| Name | Input | Output |
|
||
|
|
| ---- | ----- | ------ |
|
||
|
|
| Put | [PutRequest](#container.PutRequest) | [PutResponse](#container.PutResponse) |
|
||
|
|
#### Method Delete
|
||
|
|
|
||
|
|
Delete container removes it from the inner ring container storage. It
|
||
|
|
also asynchronous process done by consensus.
|
||
|
|
|
||
|
|
| Name | Input | Output |
|

|
|
| ---- | ----- | ------ |
|
||
|
|
| Delete | [DeleteRequest](#container.DeleteRequest) | [DeleteResponse](#container.DeleteResponse) |
|
||
|
|
#### Method Get
|
||
|
|
|
||
|
|
Get container returns container instance
|
||
|
|
|
||
|
|
| Name | Input | Output |
|
||
|
|
| ---- | ----- | ------ |
|
||
|
|
| Get | [GetRequest](#container.GetRequest) | [GetResponse](#container.GetResponse) |
|
||
|
|
#### Method List
|
||
|
|
|
||
|
|
List returns all user's containers
|
||
|
|
|
||

|
| Name | Input | Output |

|
|
DeleteResponse is empty because delete operation is asynchronous and done
