    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 avoids running a central daemon, thus using fewer system resources and simplifying debugging and monitoring.

Possible disadvantages of rkt

    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.
