> Containers didn't become a popular tool because they don't add value. The use case for them has been clear for over four years now Well, yes, they did become popular despite not providing anything substantially new. The main value of containers is that programmer who works with network now doesn't need (initially) to understand how to configure the network, which is a dumb idea by itself. All the other things added by containers boil down to distributing a tarball with whole operating system, so you can run that in a chroot. From where I stand it seems that programmers didn't want to learn how to build, distribute, and configure software with OS packages, so they invented their own binary packages system.
