Play with Clustering
Build 3 releases that can run on the same machine::
make devrel
Start them in different consoles::
make dev1-console
make dev2-console
make dev3-console
join 2 nodes to the first one::
make devrel-join
check the status of the cluster::
make devrel-status
you should see something like this::
================================= Membership ==================================
Status Ring Pending Node
-------------------------------------------------------------------------------
joining 0.0% -- '[email protected]'
joining 0.0% -- '[email protected]'
valid 100.0% -- '[email protected]'
-------------------------------------------------------------------------------
Valid:1 / Leaving:0 / Exiting:0 / Joining:2 / Down:0
it should say that 3 nodes are joining, now check the cluster plan::
make devrel-cluster-plan
it should display the cluster plan, now we can commit the plan::
make devrel-cluster-commit
check the status of the cluster again::
make devrel-status
you could see the vnodes transfering::
================================= Membership ==================================

Valid:3 / Leaving:0 / Exiting:0 / Joining:0 / Down:0
at some point you should see something like this::

valid 33.3% -- '[email protected]'
valid 33.3% -- '[email protected]'

Valid:3 / Leaving:0 / Exiting:0 / Joining:0 / Down:0
when you are bored you can stop them::
make devrel-stop
