本地k8s集群的搭建

慢慢慢时光2025-07-21 20:39

windows机器，考虑如果使用云服务器，每年的开销还是太大，不值得，自己只是做demo，了解各种配置和使用即可，使用VMware的虚拟机来搭建k8s集群

使用docker安装rancher和k8s

复制代码

yum -y install chrony

cat > /etc/chrony.conf <<-'EOF'
pool 192.168.200.135 iburst
driftfile /var/lib/chrony/drift 
makestep 1.0 3 
rtcsync
allow 192.168.200.0/24
local stratum 10
keyfile /etc/chrony.keys
leapsectz right/UTC
logdir /var/log/chrony
EOF

systemctl restart chronyd.service --now

chronyc -a makestep
chronyc sources -V
chronyc sourcestats -v
systemctl restart rsyslog;systemctl restart crond

cat > /etc/hosts <<-'EOF'

sudo sed -ri 's/.*swap.*/#&/' /etc/fstab

docker pull rancher/rancher:v2.5.2-linux-amd64

mkdir -p /mnt/d/rancher_data
docker run -d \
  --privileged \
  -p 80:80 \
  -p 443:443 \
  -v /mnt/d/rancher_data:/var/lib/rancher \
  --restart=always \
  --name rancher-v2.5.2 \
  rancher/rancher:v2.5.2-linux-amd64
  
mkdir ~/.kube
vim ~/.kube/config

k8s的监控

采用Prometheus

通过rancher UI的应用商店直接安装
