Using official Osmimis pro image + aws S3 plugin + minio = curlCode: 6, Couldn't resolve host name
Darren Gallagher
I’m testing the version 1.3.0 of the plugin in the Docker images 21.6.2, with an entirely local setup using Docker compose with local PostgreSQL and local Minio.
docker inspect osimis.azurecr.io/orthanc-pro:latest

See https://docs.min.io/docs/minio-docker-quickstart-guide.html]My docker-compose has the following configuration for the Orthanc container (this is derived from the osimis.azurecr.io/orthanc-pro:latest image but with some additional python modules being pip installed.

When I then try to POST an instance into the server I receive the following error:

To debug this I connected to the Orthanc container (docker container exec -it my-orthanc /bin/bash) and used the python REPL to test that boto3 can talk to the minio instance from the Orthance container:
root@f481526c1de2:/# export AWS_ACCESS_KEY_ID=<REDACTED>

>>> import boto3
>>> s3 = boto3.resource('s3', endpoint_url=http://minio:9000)
>>> bucket = s3.Bucket('testbucket')
>>> file_list = [s.key for s in list(bucket.objects.all())]
>>> print(file_list)
['ML Workflow.jpg', 'patch.diff']
We have had the S3 plugin working on earlier versions of the Osimis image using AWS cloud backend (e.g not minio). The new ENV VAR that I have added in local docker-compose setup are:
ORTHANC__AWS_S3_STORAGE__VIRTUALADDRESSING=false
ORTHANC__AWS_S3_STORAGE__ENDPOINT=http://minio:9000/
Has anyone else successfully used minio with Orthanc via docker-compose? Is this related to something new in the 21.6.2 release? https://bitbucket.org/osimis/orthanc-builder/src/master/release-notes-docker-images.txt
Anything else I can try?
Is the source code to the official S3 plugin available anywhere?
Thanks in advance
