Docker is only officially supported on 64-bit systems, making lxc the better choice for legacy systems.
The major difference between a Docker container and an lxc container is that a Docker container commonly runs one process, while an lxc container runs many. To deploy a database-backed web server, you need at least two Docker containers–one for the web server and one for the database server–but only one lxc container.
The Docker philosophy makes it easy to construct systems from smaller building blocks, but it can make it harder to develop blocks since so many Linux utilities are expected to run inside a full Linux system with crontab entries to carry out operations such...
