Mike Perry created AIRFLOW-839:
----------------------------------
Summary: docker_operator.py attempts to log status key without
first checking existence
Key: AIRFLOW-839
URL: https://issues.apache.org/jira/browse/AIRFLOW-839
Project: Apache Airflow
Issue Type: Bug
Components: docker
Affects Versions: Airflow 1.7.1
Environment: arch linux
python 2.7 and python 3
Reporter: Mike Perry
Assignee: Mike Perry
Priority: Trivial
When pulling a docker image, docker_operator.py attempts to log the `status`
key each time it gets output. This is usually fine, but occasionaly no `status`
key exists. We've seen this happen when we run out of inode space in our
cluster and the docker cli is unable to extract the image. This is consistent
with the docker HTTP api docs
(https://docs.docker.com/engine/api/v1.24/#create-an-image). If an error
occurs, there won't be a `status` key. There will be an `error` key.
This is a relatively minor bug, but it obscures the real issue and can
sometimes make it difficult to figure out what went wrong.
