This PR adds pass-through, single encryption at gateway and double
encryption support (gateway encryption with pass through of SSE
headers to backend).
If KMS is set up (either with Vault as KMS or using
MINIO_SSE_MASTER_KEY),gateway will automatically perform
single encryption. If MINIO_GATEWAY_SSE is set up in addition to
Vault KMS, double encryption is performed.When neither KMS nor
MINIO_GATEWAY_SSE is set, do a pass through to backend.
When double encryption is specified, MINIO_GATEWAY_SSE can be set to
"C" for SSE-C encryption at gateway and backend, "S3" for SSE-S3
encryption at gateway/backend or both to support more than one option.
Fixes#6323, #6696
Enhance a little bit the error message that is showing
when access & secret keys are not specified in the
environment when running Minio in gateway and server mode.
This commit also removes a redundant check of access/secret keys.
This PR is the first set of changes to move the config
to the backend, the changes use the existing `config.json`
allows it to be migrated such that we can save it in on
backend disks.
In future releases, we will slowly migrate out of the
current architecture.
Fixes#6182
In a small window, UI error tries to split lines for an eye candy
error message. However, since we show some docs.minio.io links in some
error messages, these links are actually broken and not easily selected
in a X terminal. This PR changes the behavior and won't split lines
anymore.
