My Zalenium is deployed in Kubernetes. I have set option desiredContainers = 2 and it's working. But sometimes desired containers are not available. Tests are working properly, even when desired containers not available. After "restart" containers appears, but I have no idea why they sometimes dissapears. Does anyone have idea what's going on?
