k3sup VS Docker Machine

• Simplicity
  k3sup simplifies the process of setting up a lightweight Kubernetes cluster by providing an easy-to-use CLI tool, reducing the manual effort involved.
• Speed
  It significantly speeds up the installation of k3s by automating many of the steps, allowing users to get a cluster up and running quickly.
• Portability
  k3sup is compatible with various environments, including Raspberry Pi, virtual machines, and cloud services, offering flexibility in deployment.
• No Overhead
  Since k3sup installs k3s without any additional overhead, it maintains the lightweight nature of the k3s distribution.
• Open Source
  Being open source, k3sup allows developers to contribute to its development and adapt the source code to suit their specific needs.

Possible disadvantages

• Limited to k3s
  k3sup is specifically designed for k3s and may not be suitable for users who need to work with larger Kubernetes distributions or have specific deployment requirements not covered by k3s.
• Basic Features
  While k3sup simplifies setup, it might lack some of the advanced features that more robust, full-featured Kubernetes management tools provide.
• Community Support
  As a smaller, community-driven project, k3sup may not offer the same level of support and resources as more established Kubernetes tools.
• Limited Automation
  Although k3sup automates the installation of k3s, further configuration and management of the cluster after setup may require additional scripting or manual intervention.
• Dependency on SSH
  k3sup relies on SSH for remote connections, which means it requires proper SSH setup and permissions, potentially complicating configurations for some users.

• Cross-platform portability
  Docker Machine enables users to create and manage Docker hosts on local machines or cloud platforms, offering seamless cross-platform portability and integration across different environments.
• Consistent environment setup
  Simplifies the process of setting up development environments, ensuring that configurations are consistent across various machines and reducing setup errors.
• Integration with multiple drivers
  Supports various infrastructure providers like AWS, Azure, Google Cloud, VirtualBox, and more, allowing for flexibility in deploying and managing containers across different platforms.
• Automated provisioning
  Automates the creation and provisioning of Docker hosts, reducing the manual steps and saving time for developers and system administrators.
• Facilitates swarm creation
  Eases the creation and management of Docker Swarm clusters, simplifying orchestration and scaling of Docker containers.

Possible disadvantages

• No longer actively maintained
  Docker Machine is deprecated and no longer actively maintained, making it less reliable for production use and missing out on the latest updates and community support.
• Complexity in management
  Managing multiple Docker Machines can become complex, especially in larger environments, requiring additional tools and scripts to handle configurations and updates efficiently.
• Limited functionality
  Compared to other modern container orchestration tools, like Kubernetes, Docker Machine offers limited functionality in terms of orchestration and scaling capabilities.
• Dependency on external tools
  Relies on external drivers and plugins which may introduce compatibility issues or require additional maintenance and troubleshooting efforts.
• Resource overhead
  Running Docker Machine, especially on local environments like VirtualBox, can introduce additional resource overhead, potentially affecting the performance and speed of operations.

• How do you archive your side hobby projects?

  I recommend learning docker first, then pick a vps host from vpsbenchmarks, then use k3sup to deploy a kubernetes cluster on that, then follow a getting-started kubernetes tutorial from there. You'll also want to buy a domain name with... Source: over 3 years ago

• What do you use as a kubernetes base?

  I just installed k3s yesterday using k3sup on 6 VMs (3 masters, 3 workers) each with 2GB RAM ( limited by the actual RAM on hardware, for now ) with Ubuntu 22.04 as the base OS. Source: over 3 years ago

• What's a cheap way to setup your own Kubernetes cluster locally or remote?

  k3s installed with k3sup, longhorn for storage, kube-vip for API VIP, and MetalLB for service load balancer using local subnet, and of course Rancher. Source: over 3 years ago
