-------------------------------------
Summary: DockerOperator failing when the docker default logging
drivers are other than 'journald','json-file'
Key: AIRFLOW-5213
URL: https://issues.apache.org/jira/browse/AIRFLOW-5213
Project: Apache Airflow
Issue Type: Bug
Components: DAG, operators
Affects Versions: 1.10.4
Reporter: venkata Bonu

Background:
Docker can be configured with multiple logging drivers.
* syslog
* local
* json - file
* journald
* local
* gelf
* fluentd
* awslogs
* splunk
* etwlogs
* gcplogs
* Logentries
But reading docker logs is supported only with drivers local , json-file ,
journald
Docker documentation:
[https://docs.docker.com/config/containers/logging/configure/]
Description:
When a docker is configured with a logging driver other than local , json-file
, jourmald , Airflow Tasks which are using DockerOperator are failing with an
error
_docker.errors.APIError: 501 Server Error: Not Implemented ("configured logging
driver does not support reading")_
Issue exists in the below lines of the code when the operator is trying to read
the logs by attaching the container.
```
{code:python}
line = ''
for line in self.cli.attach(container=self.container['Id'], stdout=True,
stderr=True, stream=True):
line = line.strip()
if hasattr(line, 'decode'):
line = line.decode('utf-8')
self.log.info(line)
{code}
```
