I don't know what language you use, but I figured out the success of Docker. I use Go, so my entire program is just one statically-linked binary. I can //go:embed any non-code files that I need at runtime. So I am naturally annoyed at the overhead Docker introduces with builds (throwing away my beloved and reliable ~/.cache for no reason), but I realize I'm not the target market, because most people don't program in a language with a build system. The target market is Python and Javascript programmers. Those languages can't even compute what modules you depend on without running arbitrary code from the Internet, much less produce a single file that will run on any reasonable Linux box. ("Hi! I got drunk and ran someone over with my motorcycle, but I'm out of jail and I need a job. Click here to give me one!" is an actual message that NPM will print in any large project, though it omits some details about the whole killing someone thing.) Docker is a system for shipping your laptop to production, and because of the inadequacies in the tooling of those popular languages, it's in high demand.
