@ -339,3 +339,117 @@ All fields (`name`, `allow` and `deny`) are optionnal.
If they are present, the corresponding modifications are applied to the key, otherwise nothing is changed.
The possible flags in `allow` and `deny` are: `createBucket`.
## Bucket operations
### ListBuckets `GET /bucket`
Returns all storage buckets in the cluster.
Example response:
```json
[
{
"id": "70dc3bed7fe83a75e46b66e7ddef7d56e65f3c02f9f80b6749fb97eccb5e1033",
"globalAliases": [
"test2"
],
"localAliases": []
},
{

],

},
{

"test3"
],
"localAliases": []
},
{
"id": "e6a14cd6a27f48684579ec6b381c078ab11697e6bc8513b72b2f5307e25fff9b",
"globalAliases": [],
"localAliases": [
{
"accessKeyId": "GK31c2f218a2e44f485b94239e",
"alias": "test"
}
]
}
]
```
### GetBucketInfo `GET /bucket?id=<bucket id>`
### GetBucketInfo `GET /bucket?globalAlias=<alias>`
Returns information about the requested storage bucket.
If `id` is set, the bucket is looked up using its exact identifier.
If `globalAlias` is set, the bucket is looked up using its global alias.
(both are fast)
Example response:
```json
{
"id": "e6a14cd6a27f48684579ec6b381c078ab11697e6bc8513b72b2f5307e25fff9b",
"globalAliases": [
"alex"
],
"keys": [
{
"accessKeyId": "GK31c2f218a2e44f485b94239e",
"name": "alex",
"permissions": {
"read": true,
"write": true,
"owner": true
},
"bucketLocalAliases": [
"test"
]
}
]
}
```
### CreateBucket `POST /bucket`
Creates a new storage bucket.
Request body format:
```json
{
"globalAlias": "NameOfMyBucket"
}
```
OR
```json
{
"localAlias": {
"key": "GK31c2f218a2e44f485b94239e",
"alias": "NameOfMyBucket"
}
}
```
OR
```json
{}
```
Creates a new bucket, either with a global alias, a local one,
or no alias at all.
### DeleteBucket `DELETE /bucket?id=<bucket id>`
Deletes a storage bucket. A bucket cannot be deleted if it is not empty.
