Subject [jira] [Commented] (MESOS-9288) Allow operators to limit the number of Docker containers on a host
Date Tue, 02 Oct 2018 22:35:00 GMT

    [ https://issues.apache.org/jira/browse/MESOS-9288?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16636198#comment-16636198
] 

Gastón Kleiman commented on MESOS-9288:
---------------------------------------

Just for reference other projects do allow specifying a maximum number of containers/pods
per node.

For example the kubelet takes a [{{--max-pods}} flag|https://kubernetes.io/docs/reference/command-line-tools-reference/kubelet/]
with a default value of 110.

>             Project: Mesos
>          Issue Type: Improvement
>          Components: containerization
>    Affects Versions: 1.7.0
>            Reporter: Greg Mann
>            Priority: Major
>              Labels: containerizer, docker, mesosphere

> Since we have observed performance issues on machines where a large number (hundreds)
of Docker containers are running simultaneously, we should consider adding a Mesos configuration
flag to allow operators to limit the number of Docker containers that can be launched on a
single host.
