--------------------------------
Summary: Container stuck in PULLING when Docker daemon hangs
Key: MESOS-8573
URL: https://issues.apache.org/jira/browse/MESOS-8573
Project: Mesos
Issue Type: Improvement
Affects Versions: 1.5.0
Reporter: Greg Mann
When the {{force}} argument is not set to {{true}}, {{Docker::pull}} will
always perform a {{docker inspect}} call before it does a {{docker pull}}. If
either of these two Docker CLI calls hangs indefinitely, the Docker container
will be stuck in the PULLING state. This means that we make no further progress
in the {{launch()}} call path, so the executor binary is never executed, the
{{Future}} associated with the {{launch()}} call is never failed or satisfied,
and {{wait()}} is never called on the container. Thus, when the executor
registration timeout elapses, the agent's call to {{containerizer->destroy()}}
gets stuck waiting on the container status, and its continuation is never
invoked.
This leaves the task destined for that Docker executor stuck in TASK_STAGING
from the framework's perspective, and attempts to kill the task will fail.
