Pros of kubernetes-handbook

• Comprehensive coverage of Kubernetes concepts and components
• Available in multiple languages (Chinese and English)
• Regularly updated with the latest Kubernetes features and best practices

Cons of kubernetes-handbook

• Less hands-on approach compared to kubernetes-the-hard-way
• May be overwhelming for beginners due to its extensive content
• Lacks the step-by-step installation process for a production-ready cluster

Code Comparison

kubernetes-the-hard-way focuses on manual installation and configuration, while kubernetes-handbook provides more general information and examples. Here's a brief comparison of how they might describe setting up a pod:

kubernetes-the-hard-way:

kubectl run nginx --image=nginx

kubernetes-handbook:

apiVersion: v1
kind: Pod
metadata:
  name: nginx
spec:
  containers:
  - name: nginx
    image: nginx

kubernetes-the-hard-way emphasizes command-line operations, while kubernetes-handbook tends to use YAML manifests for resource definitions.

Both repositories serve different purposes: kubernetes-the-hard-way is designed for learning Kubernetes internals through manual setup, while kubernetes-handbook acts as a comprehensive reference guide for Kubernetes concepts and usage.

Pros of follow-me-install-kubernetes-cluster

• Provides a more detailed, step-by-step guide in Chinese, making it accessible to a broader audience
• Includes additional components like Dashboard and Heapster for monitoring and visualization
• Offers more flexibility in terms of OS support, including CentOS and Ubuntu

Cons of follow-me-install-kubernetes-cluster

• Less frequently updated compared to kubernetes-the-hard-way
• May not always reflect the latest Kubernetes best practices or versions
• Documentation is primarily in Chinese, which may limit accessibility for non-Chinese speakers

Code Comparison

kubernetes-the-hard-way:

wget -q --show-progress --https-only --timestamping \
  "https://github.com/etcd-io/etcd/releases/download/v3.4.10/etcd-v3.4.10-linux-amd64.tar.gz"

follow-me-install-kubernetes-cluster:

wget https://github.com/etcd-io/etcd/releases/download/v3.4.9/etcd-v3.4.9-linux-amd64.tar.gz
tar -xvf etcd-v3.4.9-linux-amd64.tar.gz

Both repositories provide instructions for downloading and installing etcd, but follow-me-install-kubernetes-cluster includes an additional step for extracting the downloaded archive.

Pros of kube-ladder

• Provides a structured learning path with multiple levels of difficulty
• Covers a broader range of Kubernetes topics, including advanced concepts
• Includes hands-on exercises and projects for practical experience

Cons of kube-ladder

• Less focused on the manual installation process of Kubernetes
• May not provide as detailed insights into the inner workings of Kubernetes components
• Written primarily in Chinese, which may be a barrier for non-Chinese speakers

Code Comparison

kubernetes-the-hard-way focuses on manual installation and configuration:

wget -q --show-progress --https-only --timestamping \
  "https://github.com/etcd-io/etcd/releases/download/v3.4.15/etcd-v3.4.15-linux-amd64.tar.gz"

kube-ladder emphasizes practical exercises and projects:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx

Both repositories aim to teach Kubernetes, but with different approaches. kubernetes-the-hard-way provides a deep dive into the manual setup process, offering valuable insights into the system's internals. kube-ladder, on the other hand, offers a more comprehensive curriculum covering various aspects of Kubernetes, from basics to advanced topics, with a focus on practical application through exercises and projects.

Pros of Kubespray

• Automated deployment process, reducing manual effort and potential errors
• Supports multiple platforms and cloud providers out-of-the-box
• Regularly updated and maintained by the Kubernetes community

Cons of Kubespray

• Less educational value for understanding Kubernetes internals
• May abstract away important details, making troubleshooting more challenging
• Requires more complex setup and configuration for customization

Code Comparison

Kubernetes the Hard Way (manual setup):

wget -q --show-progress --https-only --timestamping \
  "https://github.com/etcd-io/etcd/releases/download/v3.4.10/etcd-v3.4.10-linux-amd64.tar.gz"
tar -xvf etcd-v3.4.10-linux-amd64.tar.gz
sudo mv etcd-v3.4.10-linux-amd64/etcd* /usr/local/bin/

Kubespray (automated setup):

all:
  vars:
    ansible_user: ubuntu
    ansible_become: true
    kubespray_version: v2.15.0
    kube_version: v1.20.7

Kubernetes the Hard Way provides a step-by-step manual approach, offering deep insights into Kubernetes components and their interactions. It's ideal for learning but time-consuming for production deployments. Kubespray, on the other hand, automates the process, making it more suitable for production environments but potentially obscuring some underlying details.

Pros of kubeadm

• Easier and faster setup process for Kubernetes clusters
• Automated installation and configuration of components
• Regular updates and maintenance by the official Kubernetes project

Cons of kubeadm

• Less granular control over the cluster setup process
• May not provide as deep an understanding of Kubernetes internals
• Limited customization options for advanced configurations

Code Comparison

kubernetes-the-hard-way:

wget -q --show-progress --https-only --timestamping \
  "https://github.com/etcd-io/etcd/releases/download/v3.4.10/etcd-v3.4.10-linux-amd64.tar.gz"
tar -xvf etcd-v3.4.10-linux-amd64.tar.gz
sudo mv etcd-v3.4.10-linux-amd64/etcd* /usr/local/bin/

kubeadm:

sudo apt-get update && sudo apt-get install -y apt-transport-https curl
curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
sudo apt-get update
sudo apt-get install -y kubelet kubeadm kubectl

The code snippets demonstrate the difference in setup complexity. kubernetes-the-hard-way requires manual downloading and installation of components, while kubeadm simplifies the process with package management tools.
