Sealos 自定义配置

Sealos 安装操作系统时, 会有一些特殊的要求, 比如需要指定 Containerd 的主路径, 这些不可避免的会修改配置文件;

Sealos 的配置 都可通过配置文件来运行, 默认通过命令行生成的配置文件, 在~/.sealos/default/Clusterfile 中;也可以不安装, 直接通过命令生成Clusterfile

比如我的机器配置如下

master:

• 192.168.0.2

• 192.168.0.3

• 192.168.0.4

node:

• 192.168.0.5
• 192.168.0.6
• 192.168.0.7

需要安装如下安装包

• labring/kubernetes:v1.25.0
• labring/helm:v3.8.2
• labring/calico:v3.24.1

执行sealos gen 命令就可以生成对应的配置文件;

$ sealos gen labring/kubernetes:v1.25.0 labring/helm:v3.8.2 labring/calico:v3.24.1    --masters 192.168.0.2,192.168.0.3,192.168.0.4    --nodes 192.168.0.5,192.168.0.6,192.168.0.7 --passwd 'xxx' > Clusterfile

修改配置文件, 实现调整containerd 的 的存储主路径
