can't install deis with 1 coreos node

394 views Asked by At

I've tried to follow the setup, I successfully started a bare-metal (though really a VM) by installing coreos and then installing deis, however I think I have a problem of having only 1 coreos instance.

The procedure stalls at:

deisctl install platform

I can find old documentation about 1 node setups, but they seem out of date, is the 1 node (dev) setup still supported?

As of late, Deis requires a minimum of 3 nodes for both dev and production setups. This is due to ceph requiring a minimum of 3 nodes to achieve quorum.
