Here's my honest experience. Half a year ago, I used to think like that too. Then I tried everything vanilla. I used naked lxc. I used those lxc standard commands like lxc-start. I dedicated a partition as btrfs for lxc because I needed a lot of nodes based on the same base image. Then I wrote scripts to automate everything. It had been a fun experience. But it just stopped there. None of what I did was general enough to be reused. Then 3 months later, I tried docker again. I started to appreciate it. It achieve the same but was with much less effort. Documentation is not the best, but the community is really responsive. I dumped my own scripts and never looked at them again.
