Hello
let's have a look at the message displayed in Jenkins log:
INFO: Offer not sufficient for slave request:
[name: "cpus"
type: SCALAR
scalar {
value: 1.6
}
role: "*"
*==> The Mesos slave is currently offering 1.6 CPU resources*
name: "mem"
type: SCALAR
scalar {
value: 455.0
}
role: "*"
*==> The Mesos slave is currently offering 455MB of RAM resources*
name: "disk"
type: SCALAR
scalar {
value: 32833.0
}
role: "*"
==> The Mesos slave is currently offering 32GB of Disk resources
, name: "ports"
type: RANGES
ranges {
range {
begin: 31000
end: 32000
}
}
role: "*"
==> The Mesos slave is currently offering ports between 31000 & 32000
(default)
]
[]
*Requested for Jenkins slave: cpus: 0.2 mem: 704.0*
*==> Your Jenkins slave is requesting 0.2 CPU and 704 MB of RAM*
So for me it is normal that your Jenkins slave request cannot be fullfilled
by Mesos, at least by *this mesos slave, as it only has 455MB of RAM to
offer and you need 704MB*.
FYI, the requested memory for a Jenkins slave is derived from the following
calculation: *Jenkins Slave Memory in MB + (Maximum number of Executors per
Slave * Jenkins Executor Memory in MB)*.
Maybe that's why you are seeing 704MB here and not 512MB as expected.
But if you have several other Mesos slaves each offering 2CPU/2GB RAM, then
this should not be a problem and the Jenkins slave should be created on
another Mesos slave (log message is something like "offers match")
Are there any other "apps" running on your Mesos slave (another jenkins
slave, a jenkins master, ...) that would consume missing resources?
