Cannot connect to S3-Compatible object storage

[Maeva Kos]

Hi all !

I'm unable to connect to my swift object storage (S3 compatible). I'm having this error :

 om.amazonaws.AmazonClientException: Cannot instantiate a S3 client; check your AWS credentials and region


I'm confused because I can call the s3 swift api with awscli, so my config et credentials files are good.

I deployed dataverse 5.2.2 with docker : https://github.com/IQSS/dataverse-docker

This is my configuration:

config file:

[default]
region = gra

credentials file:

[default]
aws_access_key_id = *******************************
aws_secret_access_key = *****************************

I put these configuration files in the home directory of the user "payara". I think this user runs the glassfish server:

payara       6  4.5 14.6 34048336 4797192 ?    Sl   13:41   5:35 /usr/lib/jvm/zulu-8-amd64/bin/java -cp /opt/payara/appserver/glass

Any suggestions?

I don’t see anything obvious. It’s possible that swift s3 requires some additional option (the chunked-encoding option that has to be false of surf stores – I don’t know what swift needs), but I’d suspect some issue with reading the credential files first.

 

A couple ~obvious tests would be to

·         Log in as the payara user and try the aws cli – that would make sure the files are in the right place and readable by that user.

·         Make sure the URL you use with the client (aws --endpoint-url <URL> s3 ...) is the same as in your jvm option

·         Use ps –ef | grep glassfish (or similar) to verify that payara is the user account running it.

 

FWIW: The AmazonClientException: text is straight from the AWS library so there could be info on the web about this error being seen in other applications trying to use swift.

 

Hope that’s helpful,
