Timothy Chen updated MESOS-2196:
--------------------------------
Component/s: docker
> Add option to Docker containerizer to check for adequate disk space prior to
> "docker pull" on slave
> ---------------------------------------------------------------------------------------------------
>
> Key: MESOS-2196
> URL: https://issues.apache.org/jira/browse/MESOS-2196
> Project: Mesos
> Issue Type: Improvement
> Components: docker
> Affects Versions: 0.20.1
> Reporter: Lans Carstensen
>
> This is a request for a flag similar in nature to
> https://reviews.apache.org/r/28190/ to ensure that there is adequate disk
> space on a mesos-slave prior to attempting to download a Docker image. This
> would avoid negatively impacting running tasks/containers and/or running a
> system out of disk space since this machine resource is currently unmanaged.
> If space is unavailable to run a particular task, It would be desirable to be
> able to invoke a preconfigured space reclamation workflow on the slave.
> Regarding implementation on the slave, one would have to query the /info
> endpoint to find storage information from the Docker storage driver. My
> particular use case is with devicemapper. One then has to resolve the list
> of image layers associated with a particular image tag, remove the list of
> layers already downloaded, and then query the registry for each layer's size
> to determine if all layers can be downloaded.
