I am using the AWS Go SDK v2 (https://github.com/aws/aws-sdk-go-v2) to
talk to my RGW instance using the s3 interface. I am running ceph in
docker using the ceph/daemon docker images in demo mode. The RGW is
started with a zonegroup and zone with their names set to an empty
string by the scripts in the image.
I have ForcePathStyle for the client set to true, because I want to
access all my buckets using the path: myrgw.instance:8080/somebucket.
I noticed that if I set the region for the client to anything other than
us-east-1, I get this error when creating a bucket:
InvalidLocationConstraint: The specified location-constraint is not valid.
If I set the region in the client to something made up, such as "ceph"
and the LocationConstraint to "ceph", I still get the same error.
The only way to get my buckets to create successfully is to set the
client's region to us-east-1. I have grepped the ceph code base and
cannot find any references to us-east-1. In addition, I looked at the
AWS docs for calculating v4 signatures and us-east-1 is the default
region but I can see that the region string is used in the calculation
(i.e. the region is not ignored when calculating the signature if it is
set to us-east-1).
Why do my buckets create successfully if I set the region in my s3
client to us-east-1, but not otherwise? If I do not want to use
us-east-1 as my default region, for example, if I want us-west-1 as my
default region, what should I be configuring in ceph?
Thanks,
Francis
