Testing
-------
Make && Make check.
Manual test steps:
- Start Mesos master:
$ ./bin/mesos-master.sh --ip=127.0.0.1 --work_dir=/tmp/mesos-master
- Start Mesos slave:
$ ./bin/mesos-slave.sh --master=127.0.0.1:5050
- Register a framwork with `curl`
$ curl -v http://127.0.0.1:5050/api/v1/scheduler -H "Content-type:
application/json" -X POST -d @subscribe.json
$ cat subscribe.json
{
"type" : "SUBSCRIBE",
"subscribe" : {
"framework_info" : {
"user" : "root",
"name" : "comsumer c1 HTTP Framework",
"role" : "mesos",
"principal":"wyq"
},
"force" : true
}
}
And this framework will receive an offer:
{"subscribed":{"framework_id":{"value":"7de42f40-2ddd-44a1-a4ff-4af932d25e02-0000"}},"type":"SUBSCRIBED"}20
{"type":"HEARTBEAT"}680
{"offers":{"offers":[{"agent_id":{"value":"7de42f40-2ddd-44a1-a4ff-4af932d25e02-S0"},"framework_id":{"value":"7de42f40-2ddd-44a1-a4ff-4af932d25e02-0000"},"hostname":"192.168.1.5","id":{"value":"7de42f40-2ddd-44a1-a4ff-4af932d25e02-O0"},"resources":[{"name":"cpus","role":"*","scalar":{"value":8.0},"type":"SCALAR"},{"name":"mem","role":"*","scalar":{"value":15360.0},"type":"SCALAR"},{"name":"disk","role":"*","scalar":{"value":470832.0},"type":"SCALAR"},{"name":"ports","ranges":{"range":[{"begin":31000,"end":32000}]},"role":"*","type":"RANGES"}],"url":{"address":{"hostname":"192.168.1.5","ip":"192.168.1.5","port":5051},"path":"\/slave(1)","scheme":"http"}}]},"type":"OFFERS"}20
{"type":"HEARTBEAT"}20
- Update the weight of role `mesos`
$ curl --data "[{\"weight\":1.8,\"role\":\"mesos\"}]" -X PUT
http://127.0.0.1:5050/weights
Receive an rescind offer, and a new offer received:
{"rescind":{"offer_id":{"value":"7de42f40-2ddd-44a1-a4ff-4af932d25e02-O0"}},"type":"RESCIND"}680
{"offers":{"offers":[{"agent_id":{"value":"7de42f40-2ddd-44a1-a4ff-4af932d25e02-S0"},"framework_id":{"value":"7de42f40-2ddd-44a1-a4ff-4af932d25e02-0000"},"hostname":"192.168.1.5","id":{"value":"7de42f40-2ddd-44a1-a4ff-4af932d25e02-O1"},"resources":[{"name":"cpus","role":"*","scalar":{"value":8.0},"type":"SCALAR"},{"name":"mem","role":"*","scalar":{"value":15360.0},"type":"SCALAR"},{"name":"disk","role":"*","scalar":{"value":470832.0},"type":"SCALAR"},{"name":"ports","ranges":{"range":[{"begin":31000,"end":32000}]},"role":"*","type":"RANGES"}],"url":{"address":{"hostname":"192.168.1.5","ip":"192.168.1.5","port":5051},"path":"\/slave(1)","scheme":"http"}}]},"type":"OFFERS"}20
{"type":"HEARTBEAT"}20
- Update the weight of role `mesos1`
$ curl --data "[{\"weight\":2.8,\"role\":\"mesos1\"}]" -X PUT
http://127.0.0.1:5050/weights
