rkt is a game-changer for our container deployment strategy. The security model is top-notch, and the integration with our existing infrastructure was surprisingly smooth. We've seen a significant improvement in resource utilization since switching. Highly recommended for teams prioritizing security and efficiency in their containerized environments. Excellent documentation as well!
rkt has potential, but the learning curve was steeper than expected. While the pod-native approach is interesting, it introduced some complexities in our CI/CD pipeline. The documentation could be improved, especially around real-world deployment scenarios. It's a solid product, but requires a dedicated team to fully leverage its features. We have observed some challenges with scalability.
