Description
Docker is a container technology that provides a way to "wrap up a
piece of software in a complete filesystem that contains everything it
needs to run" [1]. We have experimented with Docker to investigate its
utility in three broad realms: (1) allowing existing complex software
to run in very different environments from that in which the software
was built (such as Cori, NERSC's newest supercomputer), (2) as a means
of delivering the same development environment to multiple operating
systems (including laptops), and allowing the use of tools from both
the host and container system to their best advantage, and (3) as a
way of encapsulating entire software suites (in particular, a popular
cosmology-based MCMC parameter estimation system), allowing them to be
supported for use on multiple operating systems without additional
effort. We report on the strengths and weaknesses of Docker for the
HEP community, and show results (including performance) from our
experiments.
