Can't set lock or retention on docker installed minio

[roycec]

I set up an S3 storage via docker/docker-compose. Everything works so far, data ist stored in the correct bucket/directory. Now I tried to set a policy on this storage (either a lock on the bucket or a retention policy on the files). I use the mc client binary for that, configuring and accessing the storage backend also works. But trying to set the policy ends up with errors like

mc: <ERROR> Cannot enable object lock configuration on the specified bucket. Object Lock configuration cannot be enabled on existing buckets.

I also deleted an existing bucket and tried to set the policy/lock on an empty one, but with the same result. In the case of the compliance policy on single files

Cannot set object retention on /backup/myfolder/2020-03-28T04:27:45Z_backup.zip .Bucket is missing ObjectLockConfiguration

Should the mc binary work with the docker setup? According to issue #5184, I think it should. But what I am doing wrong here?

Expected Behavior

It should be possible to use the minio client to set locks/policies on (existing?) buckets or files.

Current Behavior

Setting these policies is not possible (see error messages above)

Possible Solution

Steps to Reproduce (for bugs)

1. Set up minio (single server) with docker-compose
2. Create bucket via UI or minio client
3. Set retention policy/lock on bucket

Context

Using s3/minio for etcd snapshots. RKE in this case should handle the retention and delete files after a configured period. Due to a bug in RKE (rancher/rancher#24544) I tried to solve this via Minio retention in the meanwhile.

It should be possible to use the minio client to set locks/policies on (existing?) buckets or files.

Existing buckets it's not possible as per AWS S3 API @roycec - so it is not possible to set this on existing buckets.

How is it then possible in general?

@royec Bucket should be created with lock enabled
