Cannot configure a host in docker image minio/mc:RELEASE.2018-07-31T02-28-53Z

[ghost]

Expected behaviour

We use the minio/mc image in our CI pipelines.

We start by adding the the host with the mc config host add command.

The host should be configured and the pipeline can continue.

Actual behaviour

mc: <ERROR> Unable to initialize new config from the provided credentials. The specified bucket is not valid.

Steps to reproduce the behaviour

The following generates the error:

docker run -ti --rm minio/mc:RELEASE.2018-07-31T02-28-53Z mc config host add <minio-name> https://<path-to-our-minio>/ ${MINIO_ACCESS_KEY} ${MINIO_SECRET_KEY} S3v4

If we use the previous build there is no error:

docker run -ti --rm minio/mc:RELEASE.2018-07-13T00-53-22Z mc config host add <minio-name> https://<path-to-our-minio>/ ${MINIO_ACCESS_KEY} ${MINIO_SECRET_KEY} S3v4
