HI Rinaldo,
I think that you can use dynamic reservation feature to achieve this: You can
launch your tasks after reservation succeeds. Actually, all of the dynamic
reservation feature with endpoint has been finished except ACL part, so you can
use this feature now if you do not care ACL part.
Thanks,
Hi Guangya,
I have bene trying to get dynamic reservations to work. I downloaded the latest
from git and created a small environment on OS X 10.10. I am trying to use
reservations and I am not making much progress. I tried to get it to work
without authentication and was unable to. I used the ANY option and it still
required a principal. I am unable to configure the master to work without
authentication. Do you have some simple configs for starting a master with no
authentication required so that it can be used to set dynamic reservations.
The output below is for authentication. I tried to authenticate from a slave
and it failed with a coredump.
I start mesos like this:
mesos-master.sh —ip=nnn,nnn,nnn,nnn --work_dir=/var/lib/mesos --acls=$BASE/acls
--credentials=$BASE/credentials
bash-3.2# cat attributes/acls
{
"register_frameworks": [
{
"principals": { "type": "mesos-mach5-beta" },
"roles": { "values": "ANY" }
}
],
"run_tasks": [
{
"principals": { "values": "ANY" },
"users": { "values": "ANY" }
}
],
"shutdown_frameworks": [
{
"principals": { "values": "mesos-mach5-beta" },
"framework_principals": { "values": "ANY" }
}
]
}
bash-3.2# cat attributes/credentials
{
"credentials": [
{
"principal": "mesos-mach5-beta",
"secret": "password"
}
]
}
When I try the following I am told I am not authorized.

Hi,
I have some tasks that need to run on different types of agents. I don’t
want the tasks to run unless I am going to have all the resources. Can someone
suggest how I could accomplish that with mesos. I read about reservations
here: http://mesos.apache.org/documentation/latest/reservation/
I could iterate over all the resources I need and if I get them proceed.
Is that the only way to do it?
Any idea when coming soon will be available?
/reserve (Coming Soon)
Suppose we want to reserve 8 CPUs and 4096 MB of RAM for the ads role on a
slave with id=<slave_id>. We send an HTTP POST request to the /reserve HTTP
endpoint like so:
