How to make Minio-client (from host) talk with Minio-server(docker container)?

Question

I am running a minio-server in the container of docker-compose. I am trying to upload a file to the minio-server in the container, from the host machine (Ubuntu) (instead of container) by using minio-client (python SDK). I did not make it happen as expected. I am not clear if it is because of my endpoint(URL), or due to the connection issue between container and host?

The endpoints i tried:

url_1 = 'http://minio:9000' # from my default setup for minio link;

url_2 = 'http://localhost:9000/minio/test' # from Minio browser.

For url_1, what i got is: " botocore.exceptions.EndpointConnectionError: Could not connect to the endpoint URL: http://minio:9000/test ". The line of error: s3.create_bucket(Bucket='test')

For url_2, what i got is: " All access to this bucket has been disabled. ". The line of error: s3.create_bucket(Bucket='test')

I tried the similar thing: activating my minio-server and minio-client both in my host machine. Then i upload file from the minio-client to the minio-server. I can see those uploaded files in Minio browser in localhost.

######### python script uploading files

import boto3 from botocore.client import Config import os import getpass my_url1='http://minio:9000' # this is from os.environ['S3_URL'] my_url2='http://localhost:9000/minio/test' # this is from browser s3 = boto3.resource('s3', endpoint_url=my_url2, aws_access_key_id=os.environ['USER'], aws_secret_access_key = getpass.getpass('Password:'), config = Config(signature_version='s3v4'), region_name='us-east-1') print ('********', s3) s3.create_bucket(Bucket='test') uploadfile= os.getcwd()+'/'+'test.txt' s3.Bucket('testBucket').upload_file(uploadfile,'txt')

######### docker-yml file for Minio

minio: image: minio/minio entrypoint: - minio - server -/data ports: - "9000:9000" environment: minio_access_key = username minio_secret_key = password mc: image: minio/mc environment: minio_access_key = username minio_secret_key = password entrypoint: /bin/sh -c depends_on: minio

i expected to see the uploaded files from the minio browser('http://localhost:9000/minio/test') , just like what i did from activating minio-server and minio-client both at the host.

With default docker networking, you would have to try to access minio at http://localhost:9000 on your host. So you can just use this URL in your Python script. The http://minio:9000 will work from containers on the same docker network as your minio server.

Try to use Pyminio client instead of boto3.

import os from pyminio import Pyminio pyminio_client = Pyminio.from_credentials( endpoint='http://localhost:9000/', access_key=os.environ['USER'], secret_key=getpass.getpass('Password:') ) pyminio_client.mkdirs('/test/') pyminio_client.put_file( to_path='/test/', file_path=os.path.join(os.getcwd(), 'test.txt') )

use this configuration in your compose.yml file

version: "3" services: minio: image: "minio/minio" container_name: mi ports: - "9000:9000" environment: - "MINIO_ACCESS_KEY=ACCRESS" - "MINIO_SECRET_KEY=SECRET" restart: always command: server /data mc: image: minio/mc container_name: mc network_mode: host entrypoint: > /bin/sh -c " /usr/bin/mc config host add minio http://127.0.0.1:9000 ACCESS SECRET; /usr/bin/mc rm -r --force minio/psb-new; /usr/bin/mc mb minio/psb-new; /usr/bin/mc policy set public minio/psb-new; exit 0; " networks: elastic: driver: bridge
