Bruce Merry created MESOS-7156: ---------------------------------- Summary: Docker containerizer ignores capability requests Key: MESOS-7156 URL: https://issues.apache.org/jira/browse/MESOS-7156 Project: Mesos Issue Type: Bug Components: containerization, documentation Affects Versions: 1.1.0 Environment: Ubuntu 16.04 Reporter: Bruce Merry Priority: Minor
I'm trying to set a capability (SYS_NICE) by populating the linux_info.capability_info.capabilities field in a ContainerInfo, while using the Docker containerizer. I was expecting this to turn into a `--cap-add` argument passed to Docker, but in fact nothing happens. I also grepped the source of Mesos HEAD and there doesn't seem to be any code to pass --cap-add. Maybe this is intended, but I couldn't find anything to indicate this in the documentation or in mesos.proto, and the placement of linux_info in ContainerInfo rather than in MesosInfo led me to expect that it would be supported independently of the containerizer. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
