Implements a web interface for VersityGW with role-based access:
- Object explorer for all users to browse, upload, and download S3 objects
- Admin dashboard showing system overview and gateway status
- Admin-only user management for IAM user administration
- Admin-only bucket management for creating and configuring S3 buckets
- User authentication with automatic role-based page access
The web UI is disabled by default and only enabled with the --webui or
VGW_WEBUI_PORT env options that specify the listening address/port for
the web UI server. This preserves previous version behavior to not enable
any new ports/services unless opted in.
Login to the web UI login page with accesskey/secretkey credentials as
either user or admin account. UI functionality will auto detect login
role.
Regular users have access to the object explorer for managing files within
their accessible buckets. Admins additionally have access to user and bucket
management interfaces. The web UI is served on a separate port from the S3
server and integrates with existing S3 and Admin API endpoints.
All requests to the S3 and Admin services are signed by the browser and sent
directly to the S3/Admin service handlers. The login credentials are never
sent over the network for security purposes. This requires the S3/Admin
service to configure CORS Access-Control-Allow-Origin headers for these
requests.
We had debug output incorrectly always enabled when running the
admin API on a separate port. This fixes the debug output to only
be enabled when --debug option selected.

When attempting to delete a non-existing object in a versioning-enabled bucket while specifying a `versionId`, VersityGW previously returned an internal error if the object had a parent file object, and an `InvalidArgument` error if the object did not exist. This PR fixes both behaviors and now returns a successful response that includes the `versionId`.
`getBucketName` in the integration test utilities is responsible for generating unique bucket names using the `test-bucket-` prefix and an atomic integer. The previous implementation performed an atomic `Add` followed by a `Load`, which does not guarantee uniqueness and could result in duplicate bucket names. This has been fixed by removing the `Load` call and relying solely on the return value of the `Add` operation, which provides the updated integer value.
Fixes#1751
When an object lock–related operation is performed on an object in a bucket where Object Lock is not enabled, an `InvalidRequest` error is returned; however, the error message differs for some actions. This PR introduces a new error, `ErrMissingObjectLockConfigurationNoSpaces`, for `PutObject`, `CopyObject`, and `CreateMultipartUpload` to maintain compatibility with S3 in terms of the error message. It also adds the missing integration tests for these actions.
Fixes#1741
An object delete request without a `versionId` results in the creation of a new delete marker in versioning-enabled buckets. Even if the latest object version is locked, a new delete marker must still be created.
This implementation skips the object lock check for delete requests in versioning-enabled buckets when the `versionId` is missing, allowing the delete marker to be created as expected.
Additionally, it introduces a flag in the `createObjVersion` method in POSIX to remove unnecessary xattr attributes from an object after creating a new object version. A delete marker must not carry object-specific attributes such as tagging, legal hold, or retention. Currently, the cleanup is limited to legal hold and retention attributes, but this list will be expanded after fixing issue #1751.
Closes#1731
Implements the admin `CreateBucket` (`PATCH /:bucket/create`) endpoint and CLI command, which create a new bucket with the provided owner access key ID. The endpoint internally calls the S3 `CreateBucket` API, storing the new owner information in the request context under the `bucket-owner` key. This value is then retrieved by the S3 API layer and the backends.
The endpoint uses the custom `x-vgw-owner` HTTP header to pass the bucket owner access key ID.
The admin CLI command mirrors `aws s3api create-bucket` and supports all flags implemented by the gateway (for example, `--create-bucket-configuration`, `--acl`, `--object-ownership`, etc.).
Go's stdlib seems to handle the FreeBSD user. namespace directly, or
FreeBSD itself doesn't require it. Make this a platform-specific
feature.
Fixes: #1745
Fixes#1733Fixes#1734
The `x-amz-object-lock-retain-until-date` request header appears in the `PutObject`, `CopyObject`, and `CreateMultipartUpload` operations. This PR fixes the two types of error codes and messages returned when the header value is invalid or expired and adds the corresponding integration tests.
There is some desire to have a web dashboard for the gateway. So
that we dont have to proxy all requests through the webserver
and expose credentials over the wire, the better approach would
be to enable CORS headers to allow browser requests directly to
the s3/admin service.
The default for these headers is off, so that they are only
enabled for instances that specfically want to support this
workload.
Fixes#1643
`GetBucketLocation` in S3 returns empty `LocationConstraint` if the bucket is in the `us-east-1` region. This fix returns empty `LocationConstraint` if the gateway region is `us-east-1`.
Fixes#1654Fixes#1644
CreateBucket `LocationConstraint` rejects empty values with an `InvalidLocationConstraint` error.
The `us-east-1` `LocationConstraint` is considered invalid because it is the default value and must not be present in the `CreateBucketConfiguration` request body.
This PR fixes both issues by returning `InvalidLocationConstraint` in both cases.
Fixes#1688
S3 returns a specific `InvalidRequest` error for the requests with `?versions` query param against `object` resource. The PR implements this error route.
Fixes#1707
The `Expect` HTTP header is ignored by the AWS SDK SigV4 signer and is omitted during signature calculation. As a result, the signature is computed incorrectly when the `Expect` header is included in the signed headers. This PR removes the `Expect` header from the SigV4 ignored headers list in the SDK-derived source code.
Fixes#1698
`PutObjectTagging`, `GetObjectTagging` and `DeleteObjectTagging` return the `x-amz-version-id` in the response headers. The PR adds this header in the responses.
Fixes#1686
GetObjectTagging previously returned a `NoSuchTagSet` error when no object tags were set. This has been fixed, and an empty tag set is now returned instead.
Fixes#1708
This PR focuses on evaluating the `x-amz-if-none-match` precondition header for object PUT operations. If any value other than `*` is provided, a `NotImplemented` error is returned. If `If-Match` is used together with `If-None-Match`, regardless of the value combination, a `NotImplemented` error is returned. When only `If-None-Match: *` is specified, a `PreconditionFailed` error is returned if the object already exists in `PutObject` or `CompleteMultipartUpload`; if the object does not exist, object creation is allowed.
