FROM minio/minio

# The next step is to define the environment variables that will be used by the MinIO service. 
# These include the access key and secret key for authentication, the bucket name for storing objects, and the port number for exposing the service. 
# We can use the environment instruction in docker-compose file to do this:

environment:
    MINIO_ACCESS_KEY: minio
    MINIO_SECRET_KEY: minio123
    MINIO_BUCKET: mybucket
    MINIO_PORT: 9000

# The third step is to create the bucket that will store our objects. 
# We can use the RUN instruction to execute a command that will use the MinIO client (mc) to create the bucket. 
# We need to make sure that the MinIO client is installed in our image before running this command. 
# We can use the apk command to install it from Alpine's package manager:

RUN apk add --no-cache minio-client && \
    mc config host add myminio http://localhost:9000 $MINIO_ACCESS_KEY $MINIO_SECRET_KEY && \
    mc mb myminio/$MINIO_BUCKET

# The final step is to specify the command that will run when our container is started. 
# We want to run the MinIO server with the specified port and bucket name. 
# We can use the CMD instruction to do this:

CMD ["server", "--address", ":$MINIO_PORT", "/data/$MINIO_BUCKET"]
