numPorts configuration question

We are running singularity with Mesos.
we configure the job with numPorts
config option
singularityDeploy:
resources:
numPorts: 3
We can see that job is given with 3 ports PORT0
, PORT1
, PORT2
, that are exactly what we expect.
The question is about values of these ports.
For example, we are given
PORT0=31842
PORT1=31843
PORT2=31844
In this example PORT0 < PORT1 < PORT2
And the question is - does this statement always hold or port values can be different ?
For example:
PORT0=31842
PORT1=31855
PORT2=31856
I am asking because we are considering using of port ranges for some our applications (like PORT0
- PORT2
)
I did not find the answer in documentation.
Thanks.

Few things:
- The ports returned are chosen from mesos offers. So the port range you allcate to your mesos agent in
--resources
is the full available set of ports - These are generally in ascending order, but there is not anything that enforces that
- Singularity doesn't have any support for port ranges, just requested counts of ports needed
