After upgrading from 1.10.9 to 1.10.10, you may see the following error:
```
[2020-04-20 23:14:44,087] {{docker_operator.py:267}} INFO - Pulling docker
image XXXX:latest
[2020-04-20 23:14:44,140] {{taskinstance.py:1145}} ERROR - 'dict' object has
no attribute 'decode'
Traceback (most recent call last):
File
"/usr/local/lib/python3.7/site-packages/airflow/models/taskinstance.py", line
983, in _run_raw_task
result = task_copy.execute(context=context)
File
"/usr/local/lib/python3.7/site-packages/airflow/operators/docker_operator.py",
line 269, in execute
output = json.loads(l.decode('utf-8').strip())
AttributeError: 'dict' object has no attribute 'decode'
```
You can patch this in your Dockerfile by adding the following (per
@brokenjacobs above):
```
RUN sed -i '268s/l/output/'
/usr/local/lib/python3.7/site-packages/airflow/operators/docker_operator.py
RUN sed -i '269s/output/#output/'
/usr/local/lib/python3.7/site-packages/airflow/operators/docker_operator.py
```
