> The vast majority of comments have nothing to do with containerization which is the purpose of Docker and unfortunately Docker just isn't that great at it. Meanwhile, they use it for configuration and in lieu of system administration which has multiple drawbacks and does indeed waste resources. Maybe that's because Docker largely iterates on existing container technology, and its purpose IS configuration? Nothing prevented you from containerizing processes before Docker, and initially it was merely a configuration frontend for LXC, which in turn handled all the containerization stuff. The actual value that Docker had added to good old jails/zones/chroot/lxc workflows is tooling and infrastructure for building, distributing and running images - there is nothing preventing you from creating simple similar tooling in plain Bash. Docker is largely about configuration and Dockerfiles, it doesn't create anything novel in regard to containerization tech. + It's just a popular standard.
