k3sup features and specs

  • 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 of k3sup

  • 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.

Docker Compose features and specs

  • Simplified Multi-Container Deployment
    Docker Compose allows users to define and manage multi-container applications with a single YAML file, making it easy to deploy complex applications.
  • Infrastructure as Code
    Compose files are version-controlled, enabling teams to use best practices in infrastructure as code, repeatable builds, and consistent development environments.
  • Portability
    Applications defined with Docker Compose can be shared easily and deployed in any environment that supports Docker, enhancing development and operational consistency.
  • Ease of Use
    With simple CLI commands, developers can start, stop, and manage containers, reducing the complexity of container orchestration.
  • Environment Variables
    Docker Compose supports the use of environment variables, making it easier to configure applications and manage different environments (e.g., development, testing, production).
  • Isolation
    Compose creates isolated environments for different applications, preventing conflicts and allowing for more straightforward dependency management.

Possible disadvantages of Docker Compose

  • Not Suitable for Large-Scale Production
    Docker Compose is not designed for managing large-scale, production-grade applications. For more robust orchestration and scaling, systems like Kubernetes are typically used.
  • Single Host Limitation
    Docker Compose is intended for single-host deployments, which limits its use in distributed and multi-host environments.
  • Networking Complexity
    Networking between containers can become complex, especially as the number of services grows, which may require additional configuration and management.
  • Learning Curve
    While Docker Compose simplifies many tasks, there is still a learning curve associated with understanding Docker concepts, Compose syntax, and best practices.
  • Limited Built-in Monitoring
    Docker Compose has limited built-in monitoring and logging capabilities, necessitating the use of additional tools for comprehensive monitoring.
  • Resource Management
    Docker Compose does not provide advanced resource management features, which can lead to suboptimal resource usage and potential inefficiencies.

k3sup mentions (29)

  • 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 tld-list and then provision a TLS certificate with cert-manager and letsencrypt (skip steps 1-4 because Google Cloud is overpriced).

  • 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: about 2 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: about 2 years ago
  • Easiest way to provision and configure ephemeral cluster locally
    Yeah, this is the answer, but I would use this with K3S: https://github.com/alexellis/k3sup. Source: about 2 years ago

  • Building a bot to talk to my cats
    I talk a lot about using containers for local development. The container that I always used was some running LLM container that I pulled from the Docker Hub official AI image registry.

  • How to Keep Docker Secrets Secure
    Docker includes a secrets management solution, but it doesn't work with standalone containers. You can supply secrets to your containers when you're using either Docker Compose or Docker Swarm.
