Antwort Should I use Docker or Proxmox? Weitere Antworten – Is Proxmox better than Docker
Proxmox and Docker offer distinct advantages and features, making them suitable for different application usage. Proxmox excels in virtualization and container integration, while Docker offers lightweight containerization, facilitating rapid deployment and scalability.Proxmox official support would always recommend that you run Docker in VMs, but the disadvantage to that is that VMs require more resources from the hypervisor. Running Docker in a Linux Container (LXC) will allow you to run Docker at a fraction of the resource requirements with much faster boot speeds.At the heart of Proxmox's power is its clustering capability. A cluster, in the Proxmox world, is a network of servers working together, allowing centralized management and advanced features like migration and high availability. Adding nodes to the Proxmox cluster is simple.
Can Docker run on LXC : Docker is developed in the Go language and utilizes LXC, cgroups, and the Linux kernel itself. Since it's based on LXC, a Docker container does not include a separate operating system; instead it relies on the operating system's own functionality as provided by the underlying infrastructure.
Is there anything better than Docker
Podman: Best for security-conscious developers seeking an open-source containerization tool. Podman is an open-source containerization tool and Docker alternative with daemonless architecture, rootless containers, Kubernetes integration and drop-in compatibility with Docker CLI commands.
What is Docker not good for : Do Not Use Docker if You Develop a Desktop GUI Application. Docker does not suit applications that require rich UI. Docker is mainly intended for isolated containers with console-based applications. GUI-based applications are not a priority, their support will rely on the specific case and application.
Best way to use Docker on Proxmox VE is to set up a separate VM and install/run Docker containers on there as on any other machine. Installing Docker on the Proxmox VE host is highly discouraged (it interferes with some mechanisms on which we rely).
Other important factors to consider when researching alternatives to Proxmox VE include storage. We have compiled a list of solutions that reviewers voted as the best overall alternatives and competitors to Proxmox VE, including VMware vSphere, VirtualBox, Oracle VM, and Azure Virtual Machines.
Do companies use Proxmox
Customers of Proxmox
Around the world in 2024, over 2200 companies have started using Proxmox as Virtualization Platform tool.In the debate of LXC containers vs Docker, LXC offers better performance and resource utilization. It provides bare-metal performance, ideal for resource-intensive applications. Docker is better suited for rapid deployment and portability across various environments.Whether Podman is better than Docker depends on the specific use case and requirements. Sometimes, Podman may offer better security and flexibility, but Docker may be more appropriate for certain environments or applications. Evaluating both options is important as determining which best meets the project's needs.
When it is used as a container runtime for Kubernetes, Docker is just a middle-man between Kubernetes and containerd. However, Kubernetes can use containerd directly as a container runtime, meaning Docker is no longer needed in this middle-man role.
Why not to use Docker : Do Not Use Docker if You Develop a Desktop GUI Application. Docker does not suit applications that require rich UI. Docker is mainly intended for isolated containers with console-based applications. GUI-based applications are not a priority, their support will rely on the specific case and application.
Is Docker as safe as VM : Docker is, at best, as secure as VMs or bare metal machines. Keep in mind, Docker runs on top of VMs and bare metals. If we are to consider Docker's security on its own, we need to consider what makes these isolation technologies secure and how they interact.

No, the software itself is open source and licensed under the AGPLv3.Yes, Docker is still relevant. It is one of the most popular containerization technologies and is used by millions of developers and companies around the world.
Why is Podman replacing Docker : Podman is an open-source container engine that aims to provide a more secure and lightweight alternative to Docker. It allows users to run containers without requiring a daemon, making it easier to manage and deploy containers on a variety of systems.
