Redeployment of an application takes more time

[praveenkumar]

When using CentOS ISO with minishift, redeploy an application takes a lot of time (around 10 minutes) and event logs shows following warnings/errors.
Refer: https://issues.jboss.org/browse/CDK-166

This seems like a Kubernetes issue : kubernetes/kubernetes#51835

The root cause of the issue is that Kubernetes tries to delete the POD and associated kubernetes.io~secret but it can not delete it (hence the error device or resource busy). It only happens when oc cluster up access the config/data/volume directories through symbolic links.
Here are the symbolic links which Minishift uses as we use the persistent storage partition.

hostConfigDirectory  = "/var/lib/minishift/openshift.local.config"
hostDataDirectory    = "/var/lib/minishift/hostdata"
hostVolumesDirectory = "/var/lib/minishift/openshift.local.volumes"
hostPvDirectory      = "/var/lib/minishift/openshift.local.pv"

Workaround:

Provide following flags to minishift start as

--host-config-dir /mnt/sda1/var/lib/minishift/openshift.local.config \
--host-data-dir /mnt/sda1/var/lib/minishift/hostdata \
--host-pv-dir /mnt/sda1/var/lib/minishift/openshift.local.pv \
--host-volumes-dir /mnt/sda1/var/lib/minishift/openshift.local.volumes

Since it resolved downstream because of the new version of Openshift. I am closing this now.
