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 ================================== Status Ring Pending Node ------------------------------------------------------------------------------- valid 75.0% 25.0% '[email protected]' valid 9.4% 25.0% '[email protected]' valid 7.8% 25.0% '[email protected]' ------------------------------------------------------------------------------- Valid:3 / Leaving:0 / Exiting:0 / Joining:0 / Down:0
at some point you should see something like this:
================================= Membership ================================== Status Ring Pending Node ------------------------------------------------------------------------------- valid 33.3% -- '[email protected]' 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
