学习 Kubernetes (Part 2: Minikube)

[nonocast]

前提

• 切记不要用M1的macOS去尝试minikube，否则很容易在arch不一致上出问题，比如luajit不支持arm64, 又或者打包出来的image只能支持amd64，最直接的方式就是找台云服务器会简单很多。

从零配置

• 2cpu, mem:2G, disk: 20G+
• 安装docker - Install Docker Engine on Ubuntu | Docker Documentation
• 配置docker镜像地址 Docker 入门 #74
• 安装minikube - minikube start | minikube

安装

• install: minikube start | minikube
• start: minikube start
• dashboard: minikube dashboard
• reset: minikube delete --all

国内加速

• Docker 入门 #74 配置docker国内镜像

hello-minikube

• 创建 Deployment: kubectl create deployment hello-node --image=k8s.gcr.io/echoserver:1.4

跟着官网做第一步就报错 Back-off restarting failed container, 查看错误:

• kubectl get pods
• kubectl describe pod pod-id
• kubectl logs pod-id

然后发现估计错在M1缺少luajit:

kubectl logs hello-minikube-5c5f5cddb9-jprqk -p
2022/08/20 16:18:43 [error] 1#1: failed to initialize Lua VM in /etc/nginx/nginx.conf:54
nginx: [error] failed to initialize Lua VM in /etc/nginx/nginx.conf:54
