I have added a custom resource called my_resource to my agent nodes but I can't figure out how to use it in a service.
I have verified that my custom resource shows up correctly using the CLI command dcos node --json which shows:
...
"unreserved_resources": {
"cpus": 12.0,
"disk": 174179.0,
"gpus": 3.0,
"mem": 31052.0,
"ports": "[1025-2180, 2182-3887, 3889-5049, 5052-8079, 8082-8180, 8182-32000]",
"my_resource": 3.0
},
...
How do I specify the custom resource in a service? I've tried the following JSON:
{
"id": "test-custom-resource",
"cmd": "while [ true ] ; do sleep 5; done",
"cpus": 1,
"mem": 128,
"disk": 0,
"instances": 1,
"my_resource": 1
}
but the my_resource line disappears from the service definition when I run it: dcos marathon app add test_custom_resource.json
Unfortunately, arbitrary resources are not supported in Marathon yet. Please, see this Marathon ticket for more information.
