`spread cluster start` fails to start up cluster

[hharnisc]

It's unclear how I got in this state, but I'm not able to start up a localkube cluster.

I've tried stoping/starting the cluster, removing all images and containers, re-creating a docker machine, and even going as far as re-installing docker.

The container seems to continuously restart

CONTAINER ID        IMAGE                            COMMAND             CREATED             STATUS                         PORTS               NAMES
5a1e299c3124        redspreadapps/localkube:latest   "start.sh"          15 minutes ago      Restarting (0) 2 minutes ago                       localkube

When I grab the container logs (docker log 5a1e299c3124) I get the following:

Hey @hharnisc, try to stop localkube and remove all containers with spread cluster stop -r and then restart with spread cluster start - let me know if that fixes it.

[hharnisc]

@mfburnett still no luck

$ spread cluster stop -r
Stopping container '5a1e299c3124b361b895f1279f612f1174f7c5e2e9b5287a8ae077b12708f803'
Removing container '5a1e299c3124b361b895f1279f612f1174f7c5e2e9b5287a8ae077b12708f803'

then starting it

$ spread cluster start                                           
Creating localkube container...
Starting localkube container...

then checking the cluster

$ kubectl cluster-info
The connection to the server 192.168.99.100:8080 was refused - did you specify the right host or port?

[hharnisc]

Looking at that log it looks like etcd is having a bad time. Potentially blowing up here: https://github.com/coreos/etcd/blob/master/wal/wal.go#L271

[hharnisc]

@mfburnett @ethernetdan does localkube cache anything on the host filesystem?

[hharnisc]

rm -rf ~/.localkube seems to have got me unstuck. I wish I would have thought to keep of copy of data in there so you could use it to debug. If it happens again I'll be sure to include it.

[mfburnett]

@hharnisc hm glad you got unstuck, thanks for documenting it!

It also happened to me under Turnkey Linux 14.1 but fortunately below worked.
Thanks @mfburnett

spread cluster stop -r

spread cluster start
