k8s部署 及 knative 開發環境部署

1。安裝kubeadm

版本一定要是1.26

1.25的kubelet有bug

早于1.23的版本無法編譯kanative

（都是血淚教訓嗚嗚嗚

https://blog.csdn.net/yudaxiaye/article/details/126919267

sudo apt install -y apt-transport-https ca-certificates curl

curl https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | sudo apt-key add -

cat <<EOF | sudo tee /etc/apt/sources.list.d/kubernetes.list

deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main

EOF

sudo apt update

sudo apt install -y kubeadm=1.26.1-00 kubelet=1.26.1-00 kubectl=1.26.1-00

2。安裝運作時（1.23後docker不是預設的了，我這裡裝了containerd

containerd安裝腳本我寫好了（python）

需要提前把幾個安裝包準備好：

cni，containerd，runc，containerd.service

import subprocess
import os
import shutil
def copy_file():
    shutil.copy('檔案的名字', '複制的路徑位置')

def runcmd(cmd):
    ret=subprocess.run(cmd.split(" "))
    if ret.returncode==0:
        print(">>> ",cmd," succ \n")
    else:
        print(">>> ",cmd," fail ",ret,"\n")

def trydo(cb):
    try:
        cb()        
    finally:
        print("")
    
trydo(
    lambda:runcmd("tar Cxzvf /usr/local containerd-1.6.15-linux-amd64.tar.gz")
)

shutil.copy("./containerd.service","/etc/systemd/system")
runcmd("systemctl daemon-reload")
runcmd("systemctl enable --now containerd")

runcmd("install -m 755 runc.amd64 /usr/local/sbin/runc")

runcmd("mkdir -p /opt/cni/bin")
trydo(
    lambda:runcmd("tar Cxzvf /opt/cni/bin cni-plugins-linux-amd64-v1.2.0.tgz")
)
           

3。建立叢集

首先需要有個配置檔案

關鍵的幾個地方：

advertiseAddress //專門用來通路的ip，可以是本地，外網，zerotier

imageRepository //國内通路需要代理鏡像

apiVersion: kubeadm.k8s.io/v1beta3
bootstrapTokens:
- groups:
  - system:bootstrappers:kubeadm:default-node-token
  token: abcdef.0123456789abcdef
  ttl: 24h0m0s
  usages:
  - signing
  - authentication
kind: InitConfiguration
localAPIEndpoint:
  advertiseAddress: 192.168.193.3
  bindPort: 6443
nodeRegistration:
  # criSocket: /var/run/dockershim.sock
  imagePullPolicy: IfNotPresent
  name: MasterNode
  taints: null
---
apiServer:
  timeoutForControlPlane: 4m0s
apiVersion: kubeadm.k8s.io/v1beta3
certificatesDir: /etc/kubernetes/pki
clusterName: kubernetes
controllerManager: {}
dns: {}
etcd:
  local:
    dataDir: /var/lib/etcd
imageRepository: registry.aliyuncs.com/google_containers
kind: ClusterConfiguration
kubernetesVersion: 1.26.0
networking:
  dnsDomain: cluster.local
  serviceSubnet: 10.96.0.0/12
scheduler: {}
           

4.knative 開發環境安裝

部署完照着knative步驟做就行了

https://github.com/knative/serving/blob/main/DEVELOPMENT.md

需要.ko.yaml 修改成 defaultBaseImage: docker.io/ubuntu

go語言版本1.19 需要設定環境變量：GOFLAGS=-buildvcs=false
