Disadvantages of Podman on Ubuntu

While Podman offers several advantages, there are some potential disadvantages or limitations to consider when using Podman on Ubuntu:

• Limited Ecosystem and Community Support: The Podman, on the other hand, was not as popular as the Docker and it has little community in terms of support and development. This also implies that you may stumble on fewer third-party apps, modules, and materials concerning Podman, especially Ubuntu-based ones.
• Compatibility Issues: There may be some compatibility issues or new cases where Podman works slightly different from Docker, even though it aims at working with the Docker CLI and images. This could pose an issue of challenge when trying to port existing Docker oriented work or application to Podman.
• Rootless Limitations: A clearly stated advantage that Podman repeats repeatedly is that it is inherently not root-run and can operate rootlessly. For instance, while using kernel features or system configurations, a user might find that rootless mode cannot support some features or options due to limitations in that particular form of installation.
• Networking Complexity: Configuring more sophisticated networking scenarios, for example, opening ports or creating networks, might less efficiently differ in Podman more than in Docker. This is so because Podman lacks the networking stack as implemented in Docker and what you require might be available as a tool or may warrant manual configuration.

Podman is a modern and efficient open-source tool for developing, managing, and populating consumer containers as well as images on Linux platforms. It entered the market to rival Docker by providing a daemon-less model that is easier to use and provides more layers of security to manage containers. This article is designed for anyone using Ubuntu and interested in leveraging Podman’s capabilities; if you belong to this community, read on to learn how to install and use Podman on your Ubuntu machine. This article will explain the basics of Docker, how the program can be installed and set up, and what one has to do after the installation is complete.
