Client API Incompatiliby with Utilized MinIO Version May Break Initial Setup #459

Open robertbartel opened 1 year ago

robertbartel commented 1 year ago

As discussed in #242, we are using an old MinIO version, due to a deprecated feature related to backing storage and how it relates to the way DMOD is designed. It turns out that newer versions of the MinIO client applications have a minor breaking change when used with the old service version.

The break relates to how access policies are set. In short, the version used in DMOD requires the admin policy set command and does not support the admin policy attach command. The reverse is the case for new versions of the client.

On a superficial level, this breaks the minio_init.sh helper script. Updates are pending which will at least help exit cleanly in problem situations, but not to work around them.

More importantly, it isn't possible to initialize the DMOD MinIO services - and thus, a DMOD deployment - using the currently configured version, without an older version of the MinIO client application.

Looks like https://github.com/minio/mc/releases/tag/RELEASE.2023-03-20T17-17-53Z is the breaking release of mc.

Verified that RELEASE.2023-03-20T17-17-53Z is the first version with the issue.

Based on how we check the version of the mc command in scripts/minio_init.sh, you can not use go install github.com/minio/mc@RELEASE.2023-02-28T00-12-59Z to get the last working version. You will need to either download a binary for that tag or clone the repo and run make build. Verified that this is does work, at least for me.
