Possible disadvantages of Traefik

  • Complexity
    The flexibility and range of features can make Traefik complex to configure and understand for beginners.
  • Performance Overhead
    The additional abstraction layer can introduce some performance overhead, which might be a concern in high-performance environments.
  • Limited Advanced Features
    Although Traefik covers many standard use cases, it may lack some advanced features that are found in more specialized load balancers.
  • Documentation
    While improving, the documentation can sometimes be lacking in depth or clarity, which can lead to difficulties in configuration and troubleshooting.
  • Community Support
    Although there is an active community, it may not be as vast or responsive as that of some other more established software like NGINX or HAProxy.
  • Proprietary Features
    Some advanced features are only available in the enterprise edition, which might be a constraint for users looking for a completely open-source solution.

k3s features and specs

  • Lightweight
    K3s is designed to be lightweight and less resource-intensive compared to full Kubernetes distributions, making it ideal for edge and IoT devices, as well as development environments.
  • Easy Installation
    K3s provides a simple installation process, requiring only a single binary for installation, which simplifies the setup procedure for users.
  • Low Resource Usage
    By stripping away non-essential features, K3s consumes significantly fewer resources, lowering the barrier to entry for running Kubernetes on resource-constrained environments.
  • Fully CNCF Conformant
    K3s is certified by the Cloud Native Computing Foundation (CNCF) as conformant with standard Kubernetes, meaning it follows the same API and operational model.
  • Built-In Database
    K3s includes an embedded SQLite database by default, which simplifies deployment and reduces the complexity associated with managing an external etcd cluster.
  • Automated TLS Management
    K3s has integrated support for TLS certificates management, which helps in ensuring secure communications between components without additional configuration.
  • Ecosystem Compatibility
    K3s supports popular Kubernetes add-ons and CI/CD tools, so it can be seamlessly integrated into existing Kubernetes-based workflows.

Possible disadvantages of k3s

  • Reduced Feature Set
    To keep K3s lightweight, some non-essential Kubernetes features and components are omitted or replaced, which might limit functionality for more advanced use cases.
  • Lack of Scalability
    K3s is optimized for smaller clusters and edge environments, so it may not scale as efficiently as standard Kubernetes distributions in large, enterprise-level deployments.
  • Embedded SQLite Limitations
    While the built-in SQLite database simplifies initial setup, it may not handle high write loads or offer the same reliability and performance as an external etcd cluster for production environments.
  • Community and Enterprise Support
    Although supported by the Kubernetes community, K3s may have less enterprise-grade support and fewer educational resources compared to other full-featured Kubernetes distributions.
  • Ecosystem Integration
    Certain Kubernetes tools or cloud services optimized for full Kubernetes distributions may not work seamlessly with K3s, requiring custom configurations or workarounds.
  • Limited Networking Options
    K3s might have fewer networking configuration options compared to full-featured Kubernetes implementations, potentially restricting advanced network setup.
  • Simplified Security Model
    K3s implements a simplified security model which might lack some advanced security features and policies found in the standard Kubernetes distribution.

  • Adventures in Homelabbing: From Cloud Obsession to Self-Hosted Shenanigans
    I began to self-host a Minecraft server using Crafty Controller, an Excalidraw instance, Docmost to replace Notion, Plane to replace Jira, and Penpot to replace Figma. To be able to access them from the internet, I used Nginx Proxy Manager to set up reverse proxies with SSL. You can use Traefik or Caddy instead, but I enjoyed the ease-of-use of NPM. For a dashboard solution, I started with Homarr, but later... - Source: dev.to / 21 days ago
  • Nginx vs Traefik: Which Reverse Proxy is Right for You?
    Before diving into the specifics of Nginx and Traefik, let’s quickly define what a reverse proxy is. A reverse proxy sits between the client (browser or other services) and your backend services (web servers or applications). It handles incoming requests, routes them to the appropriate backend service, and forwards the response to the client. Reverse proxies are typically used for:. - Source: dev.to / 3 months ago
  • Opening Pandora's Container - How Exposing the Docker Socket Paves the Way to Host Control (Part 1)
    You may wonder why one would even want to expose the Docker socket when there are clearly risks involved. A popular usecase besides accessing remote Docker daemons (which you can actually expose over a TCP socket) are applications that either need control of the daemon to manage other containers, like for example Portainer, or tools that need information about containers for auto discovery purposes, like Traefik.... - Source: dev.to / 7 months ago
  • The Home Server Journey - 3: An Actually Global "Hello"
    I emphasize usually because K3s is different and comes with a Traefik-based ingress controller by default. Taking that into account, as much as I like NGINX outside the container's world, I'd rather keep things simple and use what's already in place. - Source: dev.to / 8 months ago
  • Running Docker based web applications in Hashicorp Nomad with Traefik Load balancing
    In previous post, we discussed creating a basic Nomad cluster in the Vultr cloud.
