We need to include the logic to verify presence of versioned image tarballs before attempting to fetch/tar the test images. If the image for the specified version/tag is available, the image fetch/tar operations should be skipped.

The proposed changes to reduce CI time by making use of pre-pulled images uses a single tar bundle to hold all the test images. While this does help with improving CI time, a better approach would be to maintain the image tars separately and load them individually. Reasons :
Currently the application specification YAML files use "latest" tag for some images, and other version-based tags for others. It is necessary to identify changes to the images using "version"-based tags using a separate logic on the test harness machine
With current logic, even on changes to any one application/test image, the whole tar bundle will be re-applied

A base box with all the dependencies needs to be created. Only check-out of the code should be dynamic. This should help in reducing the time taken to setup new development VM.
OpenEBS VSM comprises of two types of containers: frontend/controller and backend/replica. backend/replica are associated with a minion node and store the data onto a disk attached to the minions. A VSM can have one or more backend/replica for providing data availability in case of node loss.
The yaml specs for launching the jiva controller and replica are at : https://github.com/openebs/elves/tree/master/k8s-dev/examples/openebs
Launching a VSM involves three steps:
With k8s pods, the IP address to the pod is assigned at runtime, so the yaml file doesnt pass the the IP address (param "listen"). Some of the issues hit when listen parameter is not specified:
(a) replica passes an empty address to controller for auto-registration. the controller can't reach the replica.
(b) controller provides an empty ip address for the iscsi discovery request, so the client can't connect to it.
