sealos 创建单节点集群

1. sealos 安装

2. 创建一个k8s集群

  1. 方式1
    参考 kuberentes-life-cycle
# sealos version must >= v4.1.0
$ sealos run labring/kubernetes:v1.25.0 labring/helm:v3.8.2 labring/calico:v3.24.1 --single
  1. 方式2
    创建Clusterfile文件
apiVersion: apps.sealos.io/v1beta1
kind: Cluster
metadata:
  creationTimestamp: null
  name: default
spec:
  hosts:
  - ips:
    - 172.16.51.5:22
    roles:
    - master
    - amd64
#  - ips:
#    - 172.16.51.12:22
#    roles:
#    - node
#    - amd64
  image:
  - labring/kubernetes-docker:v1.26.1
  - labring/helm:v3.10.3
  - labring/calico:v3.25.0
  ssh:
    passwd: ${ssh登录密码}
    pk: /root/.ssh/id_rsa
    port: 22
    user: root
status: {}
 
# 执行安装  
sealos apply -f Clusterfile

3. 允许master节点调度pod

kubectl taint node ${master节点名称} node-role.kubernetes.io/control-plane:NoSchedule-

4. 部署nginx-ingress

常见错误处理

invalid capacity 0 on image filesystem

1.修改/etc/default/grub

添加一行

GRUB_CMDLINE_LINUX="cgroup_enable=cpu"
