Error initiating docker client. Python hang after trying to find config file

python hangs on this messages:

2019-04-12 14:13:52,323 [MainThread  ] [DEBUG]  Trying paths: ['/root/.docker/config.json', '/root/.dockercfg']
2019-04-12 14:13:52,323 [MainThread  ] [DEBUG]  No config file found

this is the code:

client = docker.from_env()
    volumes={
    work_dir+'input/album': {'bind': '/code/images', 'mode': 'rw'},
    work_dir+'output/odm_orthophoto': {'bind': '/code/odm_orthophoto', 'mode': 'rw'},

    work_dir+'output/odm_dem': {'bind': '/code/odm_dem', 'mode': 'rw'}
    }

    try:
        container = client.containers.run('opendronemap/opendronemap', command="--skip-3dmodel --time --dtm --dsm", volumes=volumes, auto_remove=True, tty=True, stdin_open=True, detach=False)
        
    except docker.errors.ContainerError:
        logging.error('ERROR: Erro na execução do container docker')
        error = {
            'code': 6,
            'message': 'Erro na execução do container docker'
        }
        
  
        runCommand("sh /home/vantum/vantum-scripts/shutdown.sh")

        sys.exit()
    except docker.errors.ImageNotFound:
        logging.error('ERROR: Imagem docker não encontrada')
        error = {
            'code': 7,
            'message': 'Imagem docker não encontrada'
        }
        
       
      
        runCommand("sh /home/vantum/vantum-scripts/shutdown.sh")

        sys.exit()
    except docker.errors.APIError:
        logging.error('ERROR: Erro na API docker')
        error = {
            'code': 8,
            'message': 'Erro na API docker'
        }
        
       
        runCommand("sh /home/vantum/vantum-scripts/shutdown.sh")

        sys.exit()
    except:
        error = {
            'code': 8,
            'message': 'Erro inesperado no docker: '+sys.exc_info()[0]
        }
        logging.error('ERROR: Erro inesperado no docker: '+error)
        
        logging.info('Saving memory logs')

       
        runCommand("sh /home/vantum/vantum-scripts/shutdown.sh")

        sys.exit()
        raise

Sometimes it gives me except on error code 8, but no error given.

by the way is there a way to store logs on a file?

Start with the shown docker.from_env() call and the DEBUG output for the missing Docker configuration files. Reproduce the hang using the provided client initialization and container call, then trace where execution stops; done means identifying the cause and verifying that the resulting error or logging behavior is observable.
