Pros
Pro Allows for portable application deployment
Docker creates a single object, containing an application with its dependencies, that can be moved between any docker-enabled machines, guaranteeing the same environment for application execution.
Pro Git-like capabilities
Docker tracks changes in systems. It allows for commits and rollbacks and for quick deployment due to having to deploy only the updated code.
Pro Allows re-using components
Docker essentially allows creating boilerplate systems (a LAMP stack, for example) that can be used as a starting point on multiple projects. And you can find multiple such containers already created by people in their public registry.
Pro Automatic build
Allows automatically assembling a container from its source code.
Pro Provides easy sharing and installation of containers through a public registry
Docker allows easily pushing and pulling containers to and from their public index.docker.io registry. Additionally, dotCloud maintains a list of official repositories of the more popular containers.
Pro Application-centric
Pro Works in virtualized environments
You can set up Docker within an already virtualized environment such as a virtual machine. This allows you to run Docker on Mac and Windows, among other use-cases.
Pro Low overhead
Pro Supports a wide range of isolation tools
Docker can be used with OpenVZ, systemd-nspawn, libvirt-lxc, libvirt-sandbox, qemu/kvm, BSD Jails, Solaris Zones, and chroot.
Pro Tool ecosystem
Pro Warnings
Displays wrong entries in red, e.g. paths that do no longer exist.
Pro Easy
Editing of Windows environment variables is easy, splits long lines.
Pro Resolve variables values, make easy a refactoring of PATH by extracting different elements in their own new variable
Pro Convert variables between verbatim and expandable
Windows supports referencing variables within variables, but only if they're marked in the registry as expandable, and conversion between the two types is exposed in the context menu for each variable.
Cons
Con Large image size
Con Security concerns
Con Kernel OS fragmentation
Con Simple
Some may not consider it a "power" user tool.
