&gt;The article starts off by talking about trying to run legacy applications and then just casually tells you to modify the source code to solve all your problems. Not everything you want to run in a container is something which you want to modify.<p>I think it goes without saying that practicality&#x2F;pragmatism trumps convention or philosophy every time. I suppose the question we have to ask ourselves every day is &quot;are we being resistant to change or are we being pragmatic?&quot; Anyway, he does cover this when he mentions applications you don&#x27;t have control over. So I&#x27;m not sure it&#x27;s a fair criticism. This post seems to be aimed directly at developers or people with the latitude to effect change with them.
