通过ansible-playbook,以Kubeadm方式部署K8S集群(一主多从)。
kubernetes安装目录: /etc/kubernetes/ KubeConfig: ~/.kube/config Version: v1.18.3
主机说明:
系统 | ip | 角色 | cpu | 内存 | hostname |
---|---|---|---|---|---|
CentOS 7.8 | 192.168.30.128 | master | >=2 | >=2G | master |
CentOS 7.8 | 192.168.30.129 | node | >=2 | >=2G | node1 |
CentOS 7.8 | 192.168.30.130 | node | >=2 | >=2G | node2 |
CentOS 7.8 | 192.168.30.131 | node | >=2 | >=2G | node3 |
准备
- 将所有部署k8s集群的主机分组:
# vim /etc/ansible/hosts[master]192.168.30.128 hostname=master[node]192.168.30.129 hostname=node1 192.168.30.130 hostname=node2 192.168.30.131 hostname=node3
- 创建管理目录:
mkdir -p k8s/roles/{docker_install,master_install,node_install,addons_install}/{files,handlers,meta,tasks,templates,vars}cd k8s/
说明:
files:存放需要同步到异地服务器的源码文件及配置文件; handlers:当资源发生变化时需要进行的操作,若没有此目录可以不建或为空; meta:存放说明信息、说明角色依赖等信息,可留空; tasks:K8S 安装过程中需要进行执行的任务; templates:用于执行 K8S 安装的模板文件,一般为脚本; vars:本次安装定义的变量
