The presentation discusses Intuit's migration from 'dockerd' to 'containerd' as the CRI runtime for their Kubernetes clusters, and the challenges they faced during the process.
- Intuit had over 200 Kubernetes clusters with 20,000 nodes running 'dockerd' as the CRI runtime
- The upcoming removal of dockerd from upstream Kubernetes prompted the migration to containerd
- Lessons learned during the migration process, including issues with log management, SELinux, and GPU support
- Rollout of containerd to production clusters and handling compatibility issues during cluster upgrades
- Performance analysis showed that containerd had lower startup times and CPU consumption compared to dockerd
