Docker is the leading container technology at present. However, it should be pointed out that alternatives do exist. One such alternative is the rkt engine, which is part of the CoreOS project. We can find out more about rkt at: https://coreos.com/rkt/.

Following the recent explosive growth in container technology, there has been a drive to push for binary and runtime standardization among interested parties in this space. The standardization effort is being led by the open container initiative. We can read about their work at: https://www.opencontainers.org/.
