rkt features and specs

  • Compatibility
    rkt supports the App Container (appc) spec and can also run Docker container images, providing flexibility and compatibility with various container formats.
  • Security
    rkt is designed with security in mind, offering features like process isolation through Linux namespaces, user namespaces, and SELinux/AppArmor integration.
  • Isolation
    rkt runs applications in their own stage1 environments, ensuring strong isolation between containers and better resource management.
  • Modularity
    rkt is built with a modular architecture, allowing users to swap out the stage1 implementation to better fit their needs.
  • Lightweight
    rkt avoids running a central daemon, thus using fewer system resources and simplifying debugging and monitoring.

Possible disadvantages of rkt

  • Maturity
    rkt is not as mature as Docker, meaning it may lack some features and integrations that have been developed for Docker.
  • Community and Ecosystem
    rkt has a smaller community and ecosystem compared to Docker, which may limit the availability of third-party tools and support.
  • Adoption
    rkt has lower adoption rates, leading to fewer tutorials, guides, and community-driven content, which can make the learning curve steeper.
  • Development Activity
    rkt's development and maintenance activity is not as high as Docker's, which could impact long-term viability and feature development.
  • Enterprise Support
    Enterprise-grade support and services for rkt may not be as widely available or comprehensive as those for Docker.

Possible disadvantages of Scalr

    Integrating Scalr with existing IT systems and processes might require additional time and resources, especially for legacy setups.
