### Environment variables

#### MINIO_ETCD_ENDPOINTS

This is comma separated list of etcd servers that you want to use as the MinIO federation back-end. This should
be same across the federated deployment, i.e. all the MinIO instances within a federated deployment should use same
etcd back-end.

      --log_caller: Comma-separated list of scopes for which to include caller information, scopes can be any of \[.*\]
      --log_output_level: Comma-separated minimum per-scope logging level of messages to output, in the form of <scope>:<level>,<scope>:<level>,... where scope can be one of \[.*\] and level can be one of \[.*\]

claim_name    (string)    JWT canned policy claim name, defaults to "policy"
claim_prefix  (string)    JWT claim namespace prefix e.g. "customer1/"
scopes        (csv)       Comma separated list of OpenID scopes for server, defaults to advertised scopes from discovery document e.g. "email,admin"
comment       (sentence)  optionally add a comment to this setting
```
