I have to say that I have some doubts here. These are the points:

• I deleted config related to spec.selector.matchLabels because I do not found the point in that condition and tests still work without any kind of problem (as long as I have been testing). Should I keep it my way? -I deleted the redirection from stderr to stdout (2>&1) from the command because I neither found the point here. Aren't both stored in the log? -I set backoffLimit to 3 and restartPolicy to Never. I think it is a good approach but perhaps it can be reduced and, if it fails, it fails.
