Segregate Scheduler¶
Overview¶
tsuru uses schedulers to chooses which node an unit should be deployed. There are two schedulers: round robin and segregate scheduler.
The default one is round robin, this page describes what the segregate scheduler does and how to enable it.
How it works¶
Segregate scheduler is a scheduler that segregates the units among pools.
First, what you need to do is to define a relation between a pool and teams. After
that you need to register nodes with the pool
metadata information, indicating
to which pool the node belongs.
When deploying an application, the scheduler will choose among the nodes within the application pool.
Configuration and setup¶
To use the segregate scheduler you need to enable the segregate mode in
tsuru.conf
:
docker:
segregate: true
Registering a node with pool metadata¶
You can use the tsuru-admin
with docker-node-add
to register or create
nodes with the pool metadata:
$ tsuru-admin docker-node-add --register address=http://localhost:2375 pool=pool1
