Docker is a stepping-stone When language-specific unikernels become the norm; the OS/kernel, platform, and application will all be released/shipped as a single immutable package. Stripping the underlying OS to the bare minimum will minimize the effective surface area for security vulnerabilities. The components and dependent modules will be tested and versioned separately. Automated builds of an entire system will be quick. Start up times will be nearly instant. Resource usage will be optimized. etc...
