Podman features and specs

  • Daemonless Architecture
    Podman does not require a daemon to run containers, which simplifies its architecture and minimizes the potential attack surface.
  • Rootless Containers
    Podman allows running containers as a non-root user, enhancing security by reducing the risk associated with running processes as the root user.
  • Kubernetes Support
    Podman has built-in support for Kubernetes, enabling easier transition and orchestration of containers at scale.
  • Compatibility with Docker CLI
    Podman provides a Docker-compatible command line interface, making it easy for users to migrate from Docker with minimal changes to their workflows.
  • Enhanced Security
    With features like user namespaces and no central daemon, Podman offers improved security compared to traditional container runtimes.
  • Open Source
    Podman is an open-source project, which provides transparency and community-driven development.

Possible disadvantages of Podman

  • Limited Ecosystem
    The ecosystem around Podman is not as extensive as that of Docker, potentially limiting the availability of third-party tools and integrations.
  • Learning Curve
    Users familiar with Docker may face a learning curve when adapting to some of Podman’s unique features and CLI differences.
  • Performance Overhead
    Running rootless containers can introduce some performance overhead due to the additional layers of user namespace translation.
  • Less Mature
    Podman is relatively newer compared to Docker, which means it might not be as battle-tested in enterprise environments.
  • Inconsistent Behavior
    Certain Podman features may behave differently than Docker, which might lead to unexpected issues during container management and automation.

Podman vs Docker: Comparing the Two Containerization Tools
Rootless processes. Because of its daemonless architecture, Podman can perform truly rootless operations. Users do not have to be granted root privileges to run Podman commands, and Podman does not have to rely on a root-privileged process.

  • Is there any Ubuntu adopters in HPC?
    I highly recommend checking out Singularity for your computational software. Running your software within containers allows you a lot of freedom, although it does create some complexity in regards to MPI based parallelization. Source: almost 3 years ago
  • How do you deploy Python applications?
    Use a singularity image to contain what you want to deploy and give access on the jump host to the image. Permissions flow from existing OS permissions. https://sylabs.io/singularity/. Source: over 3 years ago
  • Brand New HPC Sysadmin at a Major University, Where to Start?
    Singularity This is a HPC focused container system that has large industry support. You can use this to package finicky software that only runs on specific linux distributions or only allows for RPM/Deb installations. It is also another mechanism for users to bring their own software and it integrates fairly well with both Slurm and HTCondor. Source: over 3 years ago
  • Microsoft's Experimental OS – Singularity
    > and it was then when they came up with a pretty cool name for their new OS — Singularity. Or, it was then when they (intentionally?) ripped off the name of an existing, open source, OS-related project. https://sylabs.io/singularity/. - Source: Hacker News / over 3 years ago
