Despite the plethora of Docker articles here on HN, I haven't paid much attention to containers. Reading this article, I get the impression that they occupy a niche somewhere between a chroot jail and a VM.

The question is, how to deploy an application in this kind of environment? Maybe I build a minimal container and find that a DBMS works fine until it does something like dlopen("/usr/lib/libxml2.so"). Oops, rebuild the container with another library and try again.

After fixing one of the broken links in the blog post, I found this article, which describes an Oracle container:

Yeah, it's called testing. But it's no different from, say, building a server and finding that the DBMS works fine until it doesn't. The only difference is that when you fix it, you can be sure(er) that you've actually fixed it, compared to a classic server, where there is a lot of state that can obscure the real problem.

Thank you, we will fix the link.
