Possible disadvantages of Haproxy

  • Complex Configuration
    Setting up HAProxy can be complex and may require a deep understanding of its configuration syntax and options, particularly for advanced use cases.
  • Lack of Built-in GUI
    HAProxy does not come with a built-in graphical user interface (GUI), which can make management more difficult for users who prefer visual tools over command-line interfaces.
  • Steep Learning Curve
    For beginners, the learning curve can be steep due to the advanced features and extensive configuration options provided by HAProxy.
  • Limited Application Layer Features
    While HAProxy excels at load balancing and basic traffic management, it lacks some application layer features that specialized application delivery controllers (ADCs) might offer.
  • Resource Intensive
    In certain high-traffic scenarios, HAProxy may consume significant CPU and memory resources, potentially requiring hardware upgrades.

  • Building a Kubernetes Cluster from Scratch With K3s And MetalLB
    Kubernetes does not provide network load balancers for bare-metal clusters out of the box. To configure load balancers in cloud environments like AWS, Azure and GCP, Kubernetes makes an API call to the cloud provider’s API to provision a load balancer and external IP. Once the load balancer is provisioned, it populates the “External IP” information in load balancer. When running Kubernetes in a bare-metal cluster,... - Source: dev.to / about 2 months ago
  • Let's Make a k3s Cluster with Raspberry Pi and Cloudflare Tunnel
    The very first step for this project is to have your Raspberry Pi up and running. This also includes SSH set up. If you already have a running one (or more) you can skip this step. One thing I want to note here is that I personally recommend you to not use WiFi connection, instead utilize wired connection which is more reliable and fast. I occasionally experienced unexpected disconnection and had to reboot my k3s... - Source: dev.to / 5 months ago

  • Self hosted kubernetes
    Hey guys, I want to share a guide I’m pretty proud of which is talking about setting up kubernetes which leverages https://kubespray.io/#/ and https://metallb.universe.tf/ so you can host this yourself most people when spinning up kubernetes opt for k3s or get stuck with all the options or unable to setup the external ips for their services so these tools will eliminate the problem.

  • Trouble with RKE2 HA Setup: Part 2
    To avoid that, you can use a combination of haproxy and keepalived, an enterprise grade load balancer like the one from F5 or Citrix. Besides that you can also work with https://kube-vip.io or https://metallb.universe.tf. Source: over 1 year ago
