- Docker 24+ introduces modern enhancements for build flexibility, team collaboration, and multi-platform compatibility.
- Key improvements include `docker compose` CLI (Compose v2), `docker buildx` for multi-platform support, and `docker context` for environment switching.
- Legacy `docker-compose` is deprecated in favor of `docker compose` (with a space), offering better integration and performance.
- `docker buildx` enables building images for different CPU architectures (e.g., ARM and x86), ideal for Apple M1/M2 users and CI/CD pipelines.
- `docker context` allows defining and switching between multiple Docker environments (local, SSH, cloud-based).
- Other features include container image signing, improved volume management, and advanced `docker compose cp` for file transfers.
- Upgrading to Docker 24+ provides unified tooling, multi-arch builds, seamless remote deployments, and better performance.
- Future topics may cover `docker scan`, `docker init`, and Compose profiles for complex apps.
