Inclavare Containers vs Podman

Inclavare Containers is a free, open-source Linux container runtime for launching protected containers in hardware-assisted Trusted Execution Environments. It creates hardware-enforced isolation between a tenant workload and privileged cloud-provider software. Its Enclave Attestation Architecture provides remote attestation that sensitive workloads run on trusted TEE hardware. The rune component is described as compliant with the OCI Runtime specification, while documented integrations include dockerd, containerd, and pouchd. Deployment can use Occlum LibOS or WebAssembly Micro Runtime, and Rats-TLS provides an attested secured channel between heterogeneous TEEs. shim-rune handles enclave signing and management between containerd and rune; epm manages cache pools for enclave startup. The project is cloud-platform agnostic and can run on public-cloud Kubernetes platforms. It supports Kubernetes CRI, uses the OCI image format, and documents Linux hosts including Ubuntu 18.04 and Alibaba Linux 2. Installation is described through source builds or RPM/DEB repositories.

Podman manages containers, pods, and images, with workflows for finding, running, building, and sharing container workloads. It is a free, daemonless container engine with a command line comparable to Docker’s CLI; most commands can run as a regular user without additional privileges. Podman Desktop adds a graphical application for installing and working with Podman and other container engines on Windows, macOS, and Linux. It can build images from Dockerfiles or Containerfiles, pull images from remote repositories, and manage accounts for pushing images to registries. Podman can run Kubernetes YAML locally, generate YAML from pods, and deploy to existing Kubernetes environments. It can find and pull containers from Docker Hub, Quay.io, internal registries, or vendors. On macOS and Windows it listens for Docker API clients. The project lists integrations including Visual Studio Code, Cirrus CLI, GitHub Actions, and kind. Podman is licensed under Apache License 2.0. Its security foundations include rootless and daemonless containers, SELinux support, network policy enforcement, and immutable containers.
